The "DAC Playback volume" control is the only control in the path from the DAC1 data input to the speaker output, so the UCM profile for the speaker output will have its PlaybackMixerElem set to "DAC1". But userspace (pulseaudio) will set the "DAC1 Playback Volume" control to its softest setting (which is not fully muted) while still showing the speaker as being enabled at a low volume in the UI. If we were to set the SNDRV_CTL_ELEM_ACCESS_SPK_LED on the "DAC1 Playback Volume" control, this would mean then what pressing KEY_VOLUMEDOWN the speaker-mute LED (embedded in the volume-mute toggle key) would light while the UI is still showing the speaker as being enabled at a low volume, meaning that the UI and the LED are out of sync. Only after an _extra_ KEY_VOLUMEDOWN press would the UI show the speaker as being muted. The path from DAC1 data input to the speaker output does have a digital mixer with DAC1's data as one of its inputs direclty after the "DAC1 Playback Volume" control. This commit adds an emulated "DAC1 Playback Switch" control by: 1. Declaring the enable flag for that mixers DAC1 input as well as the "DAC1 Playback Switch" control both as SND_SOC_NOPM controls. 2. Storing the settings of both controls as driver-private data 3. Only clearing the mute flag for the DAC1 input of that mixer if the stored values indicate both controls are enabled. This is a preparation patch for adding "audio-mute" LED trigger support.

While doing this I accidentally also copied and kept the non-standard OVCD_TH_1500UA setting used on those models. This too low threshold is causing headsets to often be seen as headphones (without a headset-mic) and when correctly identified it is causing ghost play/pause button-presses to get detected.

This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald for finding this error in the first place.

On non-ACPI systems a warning, such as the following, is printed on boot. WARNING KERN tegra-audio-graph-card sound: ASoC: no DMI vendor name! The variable 'dmi_available' is not exported and so currently cannot be used by kernel modules without adding an accessor. However, it is possible to use the function is_acpi_device_node() to determine if the sound card is an ACPI device and hence indicate if we expect a DMI table to be present. Therefore, call is_acpi_device_node() to see if we are using ACPI and only parse the DMI table if we are booting with ACPI.

This audio Jack is a bit confusing to users since it can't report headphone/mic insertion events but it claims to support these events. And in addition, the driver already builds a headphone Jack and a mic Jack, and most of those buttons are used for headphone playback, so do some change to bind those buttons to the headphone Jack. After this change, the key events are generated from NID 0x55, and are reported to the input layer via headphone jack (NID 0x21). If there is no headphone Jack, then build an audio jack to support those buttons same as previously.

Before the start of the substream, the hardware buffer is sliced into I/O messages, the number of which is equal to the current number of periods. The size of each message is equal to the current size of one period. I/O messages are organized in an ordered queue. The completion of the I/O message indicates an elapsed period (the only exception is the end of the stream for the capture substream). Upon completion, the message is automatically re-added to the end of the queue.

Dell's laptops Inspiron 3500, Inspiron 3501, Inspiron 3505 are using Cirrus Logic CS8409 HDA bridge with CS42L42 companion codec. The CS8409 is a multichannel HD audio routing controller. CS8409 includes support for four channels of digital microphone data and two bidirectional ASPs for up to 32 channels of TDM data or 4 channels of I2S data. The CS8409 is intended to be used with a remote companion codec that implements high performance analog functions in close physical proximity to the end-equipment audio port or speaker driver. The CS42L42 is a low-power audio codec with integrated MIPI SoundWire interface or I2C/I2S/TDM interfaces designed for portable applications. It provides a high-dynamic range, stereo DAC for audio playback and a mono high-dynamic-range ADC for audio capture CS42L42 is connected to CS8409 HDA bridge via I2C and I2S.

In the case of CS8409 we do not have unsol events from NID's 0x24 and 0x34 where hs mic and hp are connected. Companion codec CS42L42 will generate interrupt via gpio 4 to notify jack events.

These receivers are compatible with one another, e.g. the Dinovo Edge keyboard can be paired with the MX5000 receiver. Like the MX5x00 receivers in HID proxy mode these receivers present themselves as a hub with multiple USB-HID devices, one for the keyboard and one for the mouse. Where they differ is that the mouse USB-device has 2 input reports for reporting mice events. It has the exact same INPUT(2) report as the MX5x00 receivers, but it also has a second INPUT(5) mouse report which is different; and when the Dinovo receivers are paired with the Dinovo keyboards the second INPUT(5) mouse report is actually used for events on the builtin touchpad. Add support for handling the Dinovo quad/bluetooth-2.0 combo receivers in HID proxy mode to logitech-dj, like we already do for the similar MX5000 and MX5500 receivers. This adds battery monitoring functionality (through logitech-hidpp) and fixes the Phone (Fn + F1) and "[A]" - "[D]" (Fn + F9 - F12) hotkeys not working on the Dinovo Edge. Note these receivers present themselves as a hub with 2 separate USB devices for the keyboard and mouse; and the logitech-dj code needs to bind to both devices (just as with the MX5x00 receivers).

This patch adds a quirk to hid-plantronics for this product ID, which will ignore the second volume key press if it happens within 5 ms from the last one that was handled. The patch was tested on the mentioned model only, it shouldn't affect other models, however, this quirk might be needed for them too. Auto-repeat (when a key is held pressed) is not affected, because the rate is about 3 times per second, which is far less frequent than once in 5 ms.

If we focus to format operation at (D), using mask (= D1) is understandable because it restricts unsupported format. But, enabling format when zero format case (= D2) is very strange, because it might enables unsupported format. This runtime->hw.formats is initialized by ULLONG_MAX at soc_pcm_hw_init(), thus becoming zero format means it can't use such format. And doing this strange format operation is only here. This patch removes strange format operation (= D2), and use standard soc_pcm_hw_update_format() for it.

And when a headset is used, then the headset-microphone does not work. According to RealTek the ALC3270 variant used in these devices does not support headsets only headphones. Since the ALC3270 is a budget version of the regular ALC5645 codec, I assume that it is using a package with less pins and the headset-mic pin is simply not connected.

WARNING KERN tegra-audio-graph-card sound: ASoC: no DMI vendor name! The initial solution suggested was to test if the card device is an ACPI one. This causes a regression visible to userspace on all Intel platforms, with UCM unable to load card profiles based on DMI information: the card devices are not necessarily ACPI ones, e.g. when the parent creates platform devices on Intel devices. To fix this problem, this patch exports the existing dmi_available variable and tests it in the ASoC core.

The RT5640_DAC2_DIG_VOL register controlled by this mixer-element has nothing to do with the Mono (Amplified) output which is only available on the ALC5640 chip and not on the ALC5642 chip. The RT5640_DAC2_DIG_VOL volume-control is the main volume control for audio coming from the I2S2 / AIF2 input of the chip and as such is also available on the ALC5642. This commit results in the following userspace visible changes: 1. On devices with an ACL5640 codec, the 'Mono DAC Playback Volume' control is renamed to 'DAC2 Playback Volume' allowing the alsa-lib mixer code to properly group it with the 'DAC2 Playback Switch' which is controlling the mute bits in the RT5640_DAC2_DIG_VOL register. Note the removal of the 'Mono DAC Playback Volume' is not an issue for userspace because the UCM profiles do not use it (the UCM profiles are shared betweent the 5640 and 5642 and only the 5640 had this control). 2. On devices with an ACL5642 codec, there now will be a new 'DAC2 Playback Volume', grouped with the 'DAC2 Playback Switch' Having a complete 'DAC2 Playback Volume' / 'DAC2 Playback Switch' pair on both variants will allow enabling hardware-volume control by setting the UCM PlaybackMasterElem to "DAC2" on devices where the I2S2/AIF2 interface of the codec is used.

ATM the UCM profiles solve this by just enabling paths to the outputs / from the input from both AIF1 and AIF2 and then relying on the DAPM framework to power-down the parts of the graph connected to the unused AIF. But in order to be able to use hardware-volumecontrol and to use the hardware mute controls, which are necessary for mute LED control, the UCM profiles need to know which AIF is actually being used. Add a new "aif:1" or "aif:2" part to the component string to provide info about the used AIF to userspace / to the UCM profiles. Note the size of byt_rt5640_components is not increased because the size of 32 chars already is big enough.

We have one problem with ACPI table, i.e. GIO0 (TLMM) block has one single memory resource to cover 3 tiles defined by SC8180X. To follow the hardware layout of 3 tiles which is already supported DT probe, it adds one function to replace the original single memory resource with 3 named ones for tiles. With that, We can map memory for ACPI in the same way as DT.

CS8409/CS42L42 Driver currently does most of the platform specific setup inside the main body of the code, however, this setup can be moved into fixup functions, to make the driver more generic. Making the driver more generic, allows the driver to use the cs_parse_auto_config function in the patch function. This function forces all of the ADCs to be permanently powered, which means the cap_sync_hook function is no longer needed to restart the stream, when the jack has been ejected. Since the codec is re-initialized on every init/resume, there is no need to add specific verbs to be run on init, and instead these can be combined with the initialization verbs, which are run on init. In addition, the extra fixup verbs are no longer required, since this is taken care of elsewhere.

The first - for I2C, and the second for UART. Each interface is independent, and the kernel detects it as a separate USB hidraw device. This commit adds I2C host adapter support.

sof_rt5682: Add ALC1015Q-VB speaker amp support This patch adds jsl_rt5682_rt1015p which supports the RT5682 headset codec and ALC1015Q-VB speaker amplifier combination on JasperLake platform. This driver also supports ALC1015Q-CG if running in auto-mode.

The reverted commit itself is a revert of c31427d0d21e ("ALSA: hda: No preallocation on x86 platforms"). It was needed because HDA allowed very big allocations, up to 1GB per stream. However as previous commit in this series changes maximum allowed allocation per stream to 4MB, we can safely revert it back. On systems where there are a lot of FrontEnds, when CONFIG_SND_HDA_PREALLOC_SIZE != 0 ALSA core allocates memory for each FE, which may cause out of memory problems due to per card limit. Force config to 0 on X86, so memory will be allocated on as needed basis.

The cause is the number of MIDI conformant data channels is passed to AM824 data block processing layer. This commit fixes the bug.

This fixes the selftests to work on systems without 0x400f0 as PM_LD_MISS_L1, and should change no behaviour for systems that the tests already worked on.

Separate pin Pull-Enable (PUEN) and pin Pull-Up/Down control (PUD) registers, for controlling both pin pull-up and pin pull-down, 2. A single pin Pull-Up control register (PUPR), for controlling pin pull-up. Add support for a variant of #2, where some bits in the single pin Pull-Up control register (PUPR) control pin pull-down instead of pin pull-up. This is the case for the "ASEBRK#/ACK" pin on R-Car M2-W, M2-N, and E2, and the "ACK" pin on RZ/G1M, RZ/G1N, RZ/G1E, and RZ/G1C. To describe such a register, SoC-specific drivers need to provide two instances of pinmux_bias_reg: a first one with the puen field filled in, listing pins with pull-up functionality, and a second one with the pud field filled in, listing pins with pull-down functionality.

or they can make them directly on their MFD parent-device. The arizona-extcon code was using runtime_pm_get/_put calls on its own child-device where as the codec drivers are using runtime_pm_get/_put calls on their parent. The arizona-extcon MFD cell/child-device has been removed and this commit is part of refactoring the arizona-extcon code into a library to be used directly from the codec drivers. Specifically this commit moves the code over to make runtime_pm_get/_put calls on the parent device (on arizona->dev) bringing the code inline with how the codec drivers do this. Note this also removes the pm_runtime_enable/_disable calls as pm_runtime support has already been enabled on the parent-device by the arizona MFD driver. This is part of a patch series converting the arizona extcon driver into a helper library for letting the arizona codec-drivers directly report jack state through the standard sound/soc/soc-jack.c functions.

Note the probe (and remove) sequence is split into 2 parts: 1. The arizona_jack_codec_dev_probe() function inits a bunch of jack-detect specific variables in struct arizona_priv and tries to get a number of resources where getting them may fail with -EPROBE_DEFER. 2. Then once the machine driver has create a snd_sock_jack through snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on the codec component, which will call the new arizona_jack_set_jack(), which sets up jack-detection and requests the IRQs. This split is necessary, because the IRQ handlers need access to the arizona->dapm pointer and the snd_sock_jack which are not available when the codec-driver's probe function runs. Note this requires that machine-drivers for codecs which are converted to use the new helper functions from arizona-jack.c are modified to create a snd_soc_jack through snd_soc_card_jack_new() and register this jack with the codec through snd_soc_component_set_jack().

The snd_soc_jack code will report the cable-type through both input_dev events and through ALSA controls and the button-presses through input_dev events. Note that this means that when the codec drivers are moved over to use the new arizona-jack.c library code instead of having a separate MFD extcon cell with the extcon-arizona.c driver, we will no longer report extcon events to userspace for cable-type changes. This should not be a problem since "standard" Linux distro userspace does not (and has never) used the extcon class interface for this. Android does have support for the extcon class interface, but that was introduced in the same release as support for input_dev cable-type events, so this should not be a problem for Android either. Note this also reduces ARIZONA_MAX_MICD_RANGE from 8 to 6, this is ok to do since this info is always provided through pdata (or defaults) and cannot be overridden from devicetree. All in-kernel users of the pdata (and the fallback defaults) define 6 or less buttons/ranges.

It will tell the Cortex-M core sound format/rate/channel, where is the data buffer, where is the period size, when to start, when to stop and when suspend or resume happen, each this behavior there is defined rpmsg command. Especially we designed the low power audio case, that is to allocate a large buffer and fill the data, then Cortex-A core can go to sleep mode, Cortex-M core continue to play the sound, when the buffer is consumed, Cortex-M core will trigger the Cortex-A core to wake up.

The mic starts to work again after running userspace app like "alsactl store". Following the lead, the evidence shows that as soon as connector status is queried, the mic can work again. So also check connector value on resume to "wake up" the USB audio to make it functional. This can be device specific, however I think this generic approach may benefit more than one device. Now the resume callback checks connector, and a new callback, reset_resume, to also restore switches and volumes.

This creativity, however, is nowadays pretty limited: 1. spin_unlock_wait() has been removed from the kernel in favor of a lock/unlock combo. Furthermore, queued spinlocks have now for a number of years no longer relied on _Q_LOCKED_VAL for the call, but any non-zero value to indicate a locked state. There were cases where the delayed locked store could lead to breaking mutual exclusion with crossed locking; such as with sysv ipc and netfilter being the most extreme. 2. The auditing Andrea did in verified that remaining spin_is_locked() no longer rely on such semantics. Most callers just use it to assert a lock is taken, in a debug nature. The only user that gets cute is NOLOCK qdisc, as of: 96009c7d500e (sched: replace __QDISC_STATE_RUNNING bit with a spin lock) ... which ironically went in the next day after c6f5d02b6a0f. This change replaces test_bit() with spin_is_locked() to know whether to take the busylock heuristic to reduce contention on the main qdisc lock. So any races against spin_is_locked() for archs that use LL/SC for spin_lock() will be benign and not break any mutual exclusion; furthermore, both the seqlock and busylock have the same scope.

Riedl" Date: Fri, 26 Feb 2021 19:12:52 -0600 Subject: [PATCH 0420/1426] powerpc/signal64: Remove non-inline calls from setup_sigcontext() The majority of setup_sigcontext() can be refactored to execute in an "unsafe" context assuming an open uaccess window except for some non-inline function calls. Move these out into a separate prepare_setup_sigcontext() function which must be called first and before opening up a uaccess window. Non-inline function calls should be avoided during a uaccess window for a few reasons: - KUAP should be enabled for as much kernel code as possible. Opening a uaccess window disables KUAP which means any code executed during this time contributes to a potential attack surface. - Non-inline functions default to traceable which means they are instrumented for ftrace. This adds more code which could run with KUAP disabled. - Powerpc does not currently support the objtool UACCESS checks. All code running with uaccess must be audited manually which means: less code -> less work -> fewer problems (in theory). A follow-up commit converts setup_sigcontext() to be "unsafe".

Use __get_user() directly in anticipation of future work to remove the trivial size optimizations from __copy_from_user(). The ppc32 implementation of get_sigset_t() previously called copy_from_user() which, unlike __copy_from_user(), calls access_ok().

So don't allow Uprobe on such prefixed instruction. There are two ways probed instruction is changed in mapped pages. First, when Uprobe is activated, it searches for all the relevant pages and replace instruction in them. In this case, if that probe is on the 64-byte unaligned prefixed instruction, error out directly. Second, when Uprobe is already active and user maps a relevant page via mmap(), instruction is replaced via mmap() code path. But because Uprobe is invalid, entire mmap() operation can not be stopped. In this case just print an error and continue. Signed-off-by: Ravi Bangoria Acked-by: Naveen N.

SPRN_SPRG_SCRATCH6 is already available. SPRN_PID is only 8 bits. We have r12 that contains CR. We only need to preserve CR0, so we have space available in r12 to save PID. Keep PID in r12 and free up SPRN_SPRG_SCRATCH5. Then In TLB miss handlers, instead of using SPRN_SPRG_SCRATCH0 and SPRN_SPRG_SCRATCH1, use SPRN_SPRG_SCRATCH5 and SPRN_SPRG_SCRATCH6 to avoid future conflicts with normal exception prologs.

From 7aa8dd67f15731f659390018b5c9fd95f5975b3d Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Fri, 12 Mar 2021 12:50:22 +0000 Subject: [PATCH 0442/1426] powerpc/32: Always enable data translation in exception prolog If the code can use a stack in vm area, it can also use a stack in linear space. Simplify code by removing old non VMAP stack code on PPC32. That means the data translation is now re-enabled early in exception prolog in all cases, not only when using VMAP stacks. While we are touching EXCEPTION_PROLOG macros, remove the unused for_rtas parameter in EXCEPTION_PROLOG_1.

Now that they are always saved, EXC_XFER_STD means to restore them and EXC_XFER_LITE means to not restore them. Most of the users of EXC_XFER_STD only need to retrieve the non volatile registers. For them there is no need to restore the non volatile registers as they have not been modified. Only very few exceptions require non volatile registers restore. Opencode the few places which require saving of non volatile registers.

This can be observed in a pseries QEMU guest that has hotplugged CPUs. If the user offlines all other CPUs of the guest, and a hotplugged CPU is now the last online CPU, trying to reclaim it will fail. The current error message in this situation returns rc with -EBUSY and a generic explanation, e.g.: pseries-hotplug-cpu: Failed to offline CPU PowerPC,POWER9, rc: -16 EBUSY can be caused by other conditions, such as cpu_hotplug_disable being true. Throwing a more specific error message for this case, instead of just "Failed to offline CPU", makes it clearer that the error is in fact a known error situation instead of other generic/unknown cause.

BCM6318 allows muxing most GPIOs to different functions. BCM6318 is similar to BCM6328 with the addition of a pad register, and the GPIO meaning of the mux register changes based on the GPIO number.

Therefore __exit must be present at runtime, at least for as long as __init code is. Additionally, for jump_label and static_call, the __exit sites must also identify as within_module_init(), such that the infrastructure is aware to never touch them after module init -- alternatives are only ran once at init and hence don't have this particular constraint. By making __exit identify as __init for MODULE_UNLOAD, the above is satisfied. So, when !CONFIG_MODULE_UNLOAD, the section ordering should look like the following, with the .exit sections moved to the init region of the module. Core section allocation order: .text .rodata __ksymtab_gpl __ksymtab_strings .note.* sections .bss .data .gnu.linkonce.this_module Init section allocation order: .init.text .exit.text .symtab .strtab [jeyu: thanks to Peter Zijlstra for most of changelog] Link: https://lore.kernel.org/lkml/YFiuphGw0RKehWsQ@gunter/ Link: https://lore.kernel.org/r/20210323142756.11443-1-jeyu@kernel.org Acked-by: Peter Zijlstra (Intel) Signed-off-by: Jessica Yu --- kernel/module.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/kernel/module.c b/kernel/module.c index 30479355ab85..173a09175511 100644 --- a/kernel/module.c +++ b/kernel/module.c @@ -2802,7 +2802,11 @@ void * __weak module_alloc(unsigned long size) bool __weak module_init_section(const char *name) { +#ifndef CONFIG_MODULE_UNLOAD + return strstarts(name, ".init") || module_exit_section(name); +#else return strstarts(name, ".init"); +#endif } bool __weak module_exit_section(const char *name) @@ -3116,11 +3120,6 @@ static int rewrite_section_headers(struct load_info *info, int flags) */ shdr->sh_addr = (size_t)info->hdr + shdr->sh_offset; -#ifndef CONFIG_MODULE_UNLOAD - /* Don't load .exit sections */ - if (module_exit_section(info->secstrings+shdr->sh_name)) - shdr->sh_flags &= ~(unsigned long)SHF_ALLOC; -#endif } /* Track but don't keep modinfo and version sections. */ From 0803a5cb5b7cf369c3e2af4108ee44d0b6e1c197 Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Mon, 29 Mar 2021 23:05:24 +0800 Subject: [PATCH 0522/1426] ASoC: dwc: Fix -Wmissing-prototypes warnings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit while CONFIG_SND_DESIGNWARE_PCM is not set, building with W=1 shows this: sound/soc/dwc/local.h:127:6: warning: no previous prototype for ‘dw_pcm_push_tx’ [-Wmissing-prototypes] void dw_pcm_push_tx(struct dw_i2s_dev *dev) { } ^~~~~~~~~~~~~~ sound/soc/dwc/local.h:128:6: warning: no previous prototype for ‘dw_pcm_pop_rx’ [-Wmissing-prototypes] void dw_pcm_pop_rx(struct dw_i2s_dev *dev) { } ^~~~~~~~~~~~~ sound/soc/dwc/local.h:129:5: warning: no previous prototype for ‘dw_pcm_register’ [-Wmissing-prototypes] int dw_pcm_register(struct platform_device *pdev) ^~~~~~~~~~~~~~~ Change these to inline functions to fix the warnings.

After enabling multiple DAI configs the current config can be sent in the callback. This patch changes the way SSP config ipc is sent to the dsp. Before it was only sent once in topology loading, but now it will be additionally sent always when stream is opened. Mechanism is similar as with HDA DAIs.

On Surface Laptops 1 and 2, this interface is used to connect the integrated keyboard. Note that this subsystem interface essentially provides a limited HID transport layer. In contrast to the generic HID interface (TC=0x15) used on newer Surface models, this interface only allows (as far as we know) for a single device to be connected and is otherwise severely limited in terms of support for feature- and output-reports. Specifically, only caps-lock-LED output-reports and a single read-only feature-report are supported.

This implementation adds a tiny layer on top of the control API which calculates the state for those LEDs using the driver callbacks. Two new access flags are introduced to describe the controls which affects the audio path settings (an easy code change for drivers). The LED resource can be shared with multiple sound cards with this code. The user space controls may be added to the state chain on demand, too. This code should replace the LED code in the HDA driver and add a possibility to easy extend the other drivers (ASoC codecs etc.).

Remove the custom implementation from the HDA driver. Move the LED initialization before snd_hda_gen_parse_auto_config() call in all drivers to create marked controls there.

There's no need or sense in creating the vio bus on bare metal systems. Which is why commit 4336b9337824 ("powerpc/pseries: Make vio and ibmebus initcalls pseries specific") made the initialisation of the vio bus only happen in LPARs. However as a result of that commit we now see errors at boot on bare metal systems: Driver 'hvc_console' was unable to register with bus_type 'vio' because the bus was not initialized. Driver 'tpm_ibmvtpm' was unable to register with bus_type 'vio' because the bus was not initialized. This happens because those drivers are built-in, and are calling vio_register_driver(). It in turn calls driver_register() with a reference to vio_bus_type, but we haven't registered vio_bus_type with the driver core. Fix it by also guarding vio_register_driver() with a check to see if we are on pseries.

Since commit 662bbcb2747c ("mm, sched: Allow uaccess in atomic with pagefault_disable()"), might_fault() doesn't fire when called from sections where pagefaults are disabled, which must be the case when using _inatomic variants of __get_user and __put_user. So the might_fault() in user_access_begin() is not a problem. There was a verification of user_mode() together with the access_ok(), but there is a second verification of user_mode() just after, that leads to immediate return. The access_ok() is now part of the user_access_begin which is called after that other user_mode() verification, so no need to check user_mode() again.

They were introduced by commit e68c825bb016 ("[POWERPC] Add inatomic versions of __get_user and __put_user"). Those variants expand to the _nosleep macros instead of expanding to the _nocheck macros. The only difference between the _nocheck and the _nosleep macros is the call to might_fault(). Since commit 662bbcb2747c ("mm, sched: Allow uaccess in atomic with pagefault_disable()"), __get/put_user() can be used in atomic parts of the code, therefore __get/put_user_inatomic() have become useless.

From: Christophe Leroy Date: Mon, 22 Mar 2021 16:37:52 +0000 Subject: [PATCH 0647/1426] powerpc/bpf: Implement extended BPF on PPC32 Implement Extended Berkeley Packet Filter on Powerpc 32 Test result with test_bpf module: test_bpf: Summary: 378 PASSED, 0 FAILED, [354/366 JIT'ed] Registers mapping: [BPF_REG_0] = r11-r12 /* function arguments */ [BPF_REG_1] = r3-r4 [BPF_REG_2] = r5-r6 [BPF_REG_3] = r7-r8 [BPF_REG_4] = r9-r10 [BPF_REG_5] = r21-r22 (Args 9 and 10 come in via the stack) /* non volatile registers */ [BPF_REG_6] = r23-r24 [BPF_REG_7] = r25-r26 [BPF_REG_8] = r27-r28 [BPF_REG_9] =

must always be set in order to host at least the tail count counter. The stack frame remains for tail calls, it is set by the first callee and freed by the last callee. r0 is used as temporary register as much as possible. It is referenced directly in the code in order to avoid misusing it, because some instructions interpret it as value 0 instead of register r0 (ex: addi, addis, stw, lwz, ...) The following operations are not implemented: case BPF_ALU64 | BPF_DIV | BPF_X: /* dst /= src */ case BPF_ALU64 | BPF_MOD | BPF_X: /* dst %= src */ case BPF_STX | BPF_XADD | BPF_DW: /* *(u64 *)(dst + off) += src */ The following operations are only implemented for power of two constants: case BPF_ALU64 | BPF_MOD | BPF_K: /* dst %= imm */ case BPF_ALU64 | BPF_DIV | BPF_K: /* dst /= imm */ Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/61d8b149176ddf99e7d5cef0b6dc1598583ca202.1616430991.git.christophe.leroy@csgroup.eu --- Documentation/admin-guide/sysctl/net.rst | 2 +- arch/powerpc/Kconfig | 2 +- arch/powerpc/net/Makefile | 2 +- arch/powerpc/net/bpf_jit.h | 4 + arch/powerpc/net/bpf_jit_comp32.c | 1069 ++++++++++++++++++++++ 5 files changed, 1076 insertions(+), 3 deletions(-) create mode 100644 arch/powerpc/net/bpf_jit_comp32.c diff --git a/Documentation/admin-guide/sysctl/net.rst b/Documentation/admin-guide/sysctl/net.rst index f2ab8a5b6a4b..685cc13f567b 100644 --- a/Documentation/admin-guide/sysctl/net.rst +++ b/Documentation/admin-guide/sysctl/net.rst @@ -64,6 +64,7 @@ two flavors of JITs, the newer eBPF JIT currently supported on: - arm64 - arm32 - ppc64 + - ppc32 - sparc64 - mips64 - s390x @@ -73,7 +74,6 @@ two flavors of JITs, the newer eBPF JIT currently supported on: And the older cBPF JIT supported on the following archs: - mips - - ppc - sparc eBPF JITs are a superset of cBPF JITs, meaning the kernel will diff --git a/arch/powerpc/Kconfig b/arch/powerpc/Kconfig index 29217437b8ac..316ab0bf8112 100644 --- a/arch/powerpc/Kconfig +++ b/arch/powerpc/Kconfig @@ -202,7 +202,7 @@ config PPC select HAVE_DEBUG_STACKOVERFLOW select HAVE_DYNAMIC_FTRACE select HAVE_DYNAMIC_FTRACE_WITH_REGS if MPROFILE_KERNEL - select HAVE_EBPF_JIT if PPC64 + select HAVE_EBPF_JIT select HAVE_EFFICIENT_UNALIGNED_ACCESS if !(CPU_LITTLE_ENDIAN && POWER7_CPU) select HAVE_FAST_GUP select HAVE_FTRACE_MCOUNT_RECORD diff --git a/arch/powerpc/net/Makefile b/arch/powerpc/net/Makefile index 969cde177880..8e60af32e51e 100644 --- a/arch/powerpc/net/Makefile +++ b/arch/powerpc/net/Makefile @@ -2,4 +2,4 @@ # # Arch-specific network modules # -obj-$(CONFIG_BPF_JIT) += bpf_jit_comp.o bpf_jit_comp64.o +obj-$(CONFIG_BPF_JIT) += bpf_jit_comp.o bpf_jit_comp$(BITS).o diff --git a/arch/powerpc/net/bpf_jit.h b/arch/powerpc/net/bpf_jit.h index fb4656986fb9..a45b8266355d 100644 --- a/arch/powerpc/net/bpf_jit.h +++ b/arch/powerpc/net/bpf_jit.h @@ -42,6 +42,10 @@ EMIT(PPC_RAW_ORI(d, d, IMM_L(i))); \ } } while(0) +#ifdef CONFIG_PPC32 +#define PPC_EX32(r, i) EMIT(PPC_RAW_LI((r), (i) < 0 ? -1 : 0)) +#endif + #define PPC_LI64(d, i) do { \ if ((long)(i) >= -2147483648 && \ (long)(i) < 2147483648) \ diff --git a/arch/powerpc/net/bpf_jit_comp32.c b/arch/powerpc/net/bpf_jit_comp32.c new file mode 100644 index 000000000000..29ce802d7534 --- /dev/null +++ b/arch/powerpc/net/bpf_jit_comp32.c @@ -0,0 +1,1069 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * eBPF JIT compiler for PPC32 + * + * Copyright 2020 Christophe Leroy + * CS GROUP France + * + * Based on PPC64 eBPF JIT compiler by Naveen N.

The number of generated __SYSCALL() macros is the same as __NR_syscalls (this is 442 as of v5.11). Hence, the array size, [__NR_syscalls] is unneeded. The designated initializer, '[nr] =', is also unneeded. This file does not need to know __NR_syscalls. Drop the unneeded include directive.

The PD controller for USB Type-C can be accessed over I2C. The client driver is part of the USB Type-C UCSI driver. Also, there exists a couple of notable IP limitations that are dealt as workarounds: - I2C transaction work on a polling mode as IP does not generate interrupt. - I2C read command sent twice to address the IP issues. - AMD NAVI GPU based products are already in the commercial market, hence some of the I2C parameters are statically programmed as they can not be part of the ACPI table.

For non-kernel memory this is not an issue as any faults of this kind are corrected by the page fault handler. For kernel memory these faults are not handled. The current solution is that there is a ptesync in flush_cache_vmap() which should be called when mapping from the vmalloc region. However, map_kernel_page() does not call flush_cache_vmap(). This is troublesome in particular for code patching with Strict RWX on radix. In do_patch_instruction() the page frame that contains the instruction to be patched is mapped and then immediately patched.

Mapping kernel memory is used when code patching with Strict RWX enabled. As suggested by Chris Riedl, turning ftrace on and off does a large amount of code patching so is a convenient way to see this kind of fault. Add a selftest to try and trigger this kind of a spurious fault. It tests for 30 seconds which is usually long enough for the issue to show up.

H_PROTECT), includes the key in bits 9-13, but currently we always set those bits to zero. In the past that hasn't been a problem because we always used key 0 for the kernel, and updateboltedpp() is only used for kernel mappings. However since commit d94b827e89dc ("powerpc/book3s64/kuap: Use Key 3 for kernel mapping with hash translation") we are now inadvertently changing the key (to zero) when we call plpar_pte_protect(). That hasn't broken anything because updateboltedpp() is only used for STRICT_KERNEL_RWX, which is currently disabled on 64s due to other bugs. But we want to fix that, so first we need to pass the key correctly to plpar_pte_protect(). We can't pass our newpp value directly in, we have to convert it into the form expected by the hcall. The hcall we're using here is H_PROTECT, which is specified in section 14.5.4.1.6 of LoPAPR v1.1. It takes a `flags` parameter, and the description for flags says: * flags: AVPN, pp0, pp1, pp2, key0-key4, n, and for the CMO option: CMO Option flags as defined in Table 189‚ If you then go to the start of the parent section, 14.5.4.1, on page 405, it says: Register Linkage (For hcall() tokens 0x04 - 0x18) * On Call * R3 function call token * R4 flags (see Table 178‚ “Page Frame Table Access flags field definition‚” on page 401) Then you have to go to section 14.5.3, and on page 394 there is a list of hcalls and their tokens (table 176), and there you can see that H_PROTECT == 0x18. Finally you can look at table 178, on page 401, where it specifies the layout of the bits for the key: Bit Function ----------------- 50-54 | key0-key4 Those are big-endian bit numbers, converting to normal bit numbers you get bits 9-13, or 0x3e00. In the kernel we have: #define HPTE_R_KEY_HI ASM_CONST(0x3000000000000000) #define HPTE_R_KEY_LO ASM_CONST(0x0000000000000e00) So the LO bits of newpp are already in the right place, and the HI bits need to be shifted down by 48.

The cause turns out to be the call to hash__mark_rodata_ro(), late in boot. Due to the way we layout text and rodata, that function actually changes the permissions for all of text and rodata to read-only plus execute. To do the permission change we use a hypervisor call, H_PROTECT. On phyp that appears to be implemented by briefly removing the mapping of the kernel text, before putting it back with the updated permissions. If any other CPU is executing during that window, it will see spurious faults on the kernel text and/or data, leading to crashes. To fix it we use stop machine to collect all other CPUs, and then have them drop into real mode (MMU off), while we change the mapping. That way they are unaffected by the mapping temporarily disappearing. We don't see this bug on KVM because KVM always use VPM=1, where faults are directed to the hypervisor, and the fault will be serialised vs the h_protect() by HPTE_V_HVLOCK.

This limit, however, is quite loose: each allocation of control set may have 1028 elements, and each element may have up to 512 bytes (ILP32) or 1024 bytes (LP64) of value data. Moreover, each control set may contain the enum strings and TLV data, which can be up to 64kB and 128kB, respectively. Totally, the whole memory consumption may go over 38MB -- it's quite large, and we'd rather like to reduce the size. OTOH, there have been other requests even to increase the max number of user elements; e.g. ALSA firewire stack require the more user controls, hence we want to raise the bar, too. For satisfying both requirements, this patch changes the management of user controls: instead of setting the upper limit of the number of user controls, we check the actual memory allocation size and set the upper limit of the total allocation in bytes. As long as the memory consumption stays below the limit, more user controls are allowed than the current limit 32. At the same time, we set the lower limit (8MB) as default than the current theoretical limit, in order to lower the risk of DoS. As a compromise for lowering the default limit, now the actual memory limit is defined as a module option, 'max_user_ctl_alloc_size', so that user can increase/decrease the limit if really needed, too.

For example Platform is not needed for DPCM BE case. Moreover, we can share snd-soc-dummy DAI for CPU-dummy / dummy-Codec in DPCM. This patch adds dummy DAI and share it when DPCM case, I beliave it can contribute to reduce memory. By this patch, CPU-dummy / dummy-CPU are set at asoc_simple_init_priv(), thus, its settings are no longer needed at DPCM detecting timing on simple-card / audio-graph. Moreover, we can remove triky Platform settings code for DPCM BE, because un-needed Platform is not created.

The host CTRL should always be 1 except in CPU idle code, so this can result in the host running with runlatch clear, and potentially switching to a different vCPU which then runs with runlatch clear as well. This has little effect on P9 machines, CTRL is only responsible for some PMU counter logic in the host and so other than corner cases of software relying on that, or explicitly reading the runlatch value (Linux does not appear to be affected but it's possible non-Linux guests could be), there should be no execution correctness problem, though it could be used as a covert channel between guests. There may be microcontrollers, firmware or monitoring tools that sample the runlatch value out-of-band, however since the register is writable by guests, these values would (should) not be relied upon for correct operation of the host, so suboptimal performance or incorrect reporting should be the worst problem.

The discourage part was described this way in the commit message: "To avoid the reported regression while still allowing the new features with single lower squashfs, do not allow decoding origin with lower null uuid unless user opted-in to one of the new features that require following the lower inode of non-dir upper (index, xino, metacopy)." The three mentioned features are disabled by default in Kconfig, so it was assumed that if they are enabled, the user opted-in for them. Apparently, distros started to configure CONFIG_OVERLAY_FS_XINO_AUTO=y some time ago, so users upgrading their kernels can still be affected by said regression even though they never opted-in for any new feature. To fix this, treat "xino=on" as "user opted-in", but not "xino=auto". Since we are changing the behavior of "xino=auto" to no longer follow to lower origin with null uuid, take this one step further and disable xino in that corner case. To be consistent, disable xino also in cases of lower fs without file handle support and upper fs without xattr support. Update documentation w.r.t the new "xino=auto" behavior and fix the out dated bits of documentation regarding "xino" and regarding offline modifications to lower layers.

In case the pin had more than one configuration, even if we set the slew rate as disabled in the device tree, the next pin configuration would set again the slew rate enabled by default, overwriting the slew rate disablement. Instead of enabling the slew rate by default for each pin configuration, enable the slew rate by default just once per pin, regardless of the number of configurations. This way the slew rate disablement will also work for cases where pins have multiple configurations.

This works for most devices but some seem having a problem. Partially this was covered for the devices with a single connector at the initialization phase (commit 086b957cc17f "ALSA: usb-audio: Skip the clock selector inquiry for single connections"), but also there are cases where the wrong clock set up is kept silently. The latter seems to be the cause of the noises on Behringer devices. In this patch, we explicitly set up the audio clock selector whenever the appropriate node is found.

As the end result, it got another type of quirk for tying both streams but starts playback always (commit 6234fdc1cede "ALSA: usb-audio: Quirk for BOSS GT-001"). Meanwhile, Mike Oliphant has tested the real implicit feedback mode for the playback again with the latest code, and found out that it actually works if the initial feedback sync is skipped; that is, on those BOSS devices, the playback stream has to be started at first without waiting for the capture URB completions. Otherwise it gets stuck. In the rest operations after the capture stream processed, we can take them as the implicit feedback source. This patch is an attempt to improve the support for BOSS devices with the implicit feedback mode in the way described above. It adds a new flag to snd_usb_audio, playback_first, indicating that the playback stream starts without sync with the initial capture completion. This flag is set in the quirk table with the new IMPLICIT_FB_BOTH type.

When applied to the XIVE interrupt controller of POWER9 and POWER10 systems, a significant drop of the interrupt rate can be observed when crossing the second node boundary. This is due to the fact that a single IPI interrupt is used for all CPUs of the system. The structure is shared and the cache line updates impact greatly the traffic between nodes and the overall IPI performance. As a workaround, the impact can be reduced by deactivating the IRQ lockup detector ("noirqdebug") which does a lot of accounting in the Linux IRQ descriptor structure and is responsible for most of the performance penalty. As a fix, this proposal allocates an IPI interrupt per node, to be shared by all CPUs of that node. It solves the scaling issue, the IRQ lockup detector still has an impact but the XIVE interrupt rate scales linearly. It also improves the "noirqdebug" case as showed in the tables below. * P9 DD2.2 - 2s * 64 threads "noirqdebug" Mint/s Mint/s chips cpus IPI/sys IPI/chip IPI/chip IPI/sys -------------------------------------------------------------- 1 0-15 4.984023 4.875405 4.996536 5.048892 0-31 10.879164 10.544040 10.757632 11.037859 0-47 15.345301 14.688764 14.926520 15.310053 0-63 17.064907 17.066812 17.613416 17.874511 2 0-79 11.768764 21.650749 22.689120 22.566508 0-95 10.616812 26.878789 28.434703 28.320324 0-111 10.151693 31.397803 31.771773 32.388122 0-127 9.948502 33.139336 34.875716 35.224548 * P10 DD1 - 4s (not homogeneous) 352 threads "noirqdebug" Mint/s Mint/s chips cpus IPI/sys IPI/chip IPI/chip IPI/sys -------------------------------------------------------------- 1 0-15 2.409402 2.364108 2.383303 2.395091 0-31 6.028325 6.046075 6.089999 6.073750 0-47 8.655178 8.644531 8.712830 8.724702 0-63 11.629652 11.735953 12.088203 12.055979 0-79 14.392321 14.729959 14.986701 14.973073 0-95 12.604158 13.004034 17.528748 17.568095 2 0-111 9.767753 13.719831 19.968606 20.024218 0-127 6.744566 16.418854 22.898066 22.995110 0-143 6.005699 19.174421 25.425622 25.417541 0-159 5.649719 21.938836 27.952662 28.059603 0-175 5.441410 24.109484 31.133915 31.127996 3 0-191 5.318341 24.405322 33.999221 33.775354 0-207 5.191382 26.449769 36.050161 35.867307 0-223 5.102790 29.356943 39.544135 39.508169 0-239 5.035295 31.933051 42.135075 42.071975 0-255 4.969209 34.477367 44.655395 44.757074 4 0-271 4.907652 35.887016 47.080545 47.318537 0-287 4.839581 38.076137 50.464307 50.636219 0-303 4.786031 40.881319 53.478684 53.310759 0-319 4.743750 43.448424 56.388102 55.973969 0-335 4.709936 45.623532 59.400930 58.926857 0-351 4.681413 45.646151 62.035804 61.830057 [*] https://github.com/antonblanchard/ipistorm Signed-off-by: Cédric Le Goater Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20210331144514.892250-9-clg@kaod.org --- arch/powerpc/sysdev/xive/common.c | 62 ++++++++++++++++++------ arch/powerpc/sysdev/xive/xive-internal.h | 2 - 2 files changed, 48 insertions(+), 16 deletions(-) diff --git a/arch/powerpc/sysdev/xive/common.c b/arch/powerpc/sysdev/xive/common.c index a9e9e57e8e73..edd000bcc9f6 100644 --- a/arch/powerpc/sysdev/xive/common.c +++ b/arch/powerpc/sysdev/xive/common.c @@ -63,8 +63,19 @@ static const struct xive_ops *xive_ops;

During the EEH MMIO error checking, the current implementation fails to map the (virtual) MMIO address back to the pci device on radix with hugepage mappings for I/O. This results into failure to dispatch EEH event with no recovery even when EEH capability has been enabled on the device. eeh_check_failure(token) # token = virtual MMIO address addr = eeh_token_to_phys(token); edev = eeh_addr_cache_get_dev(addr); if (!edev) return 0; eeh_dev_check_failure(edev); <= Dispatch the EEH event In case of hugepage mappings, eeh_token_to_phys() has a bug in virt -> phys translation that results in wrong physical address, which is then passed to eeh_addr_cache_get_dev() to match it against cached pci I/O address ranges to get to a PCI device. Hence, it fails to find a match and the EEH event never gets dispatched leaving the device in failed state. The commit 33439620680be ("powerpc/eeh: Handle hugepages in ioremap space") introduced following logic to translate virt to phys for hugepage mappings: eeh_token_to_phys(): + pa = pte_pfn(*ptep); + + /* On radix we can do hugepage mappings for io, so handle that */ + if (hugepage_shift) { + pa <<= hugepage_shift; <= This is wrong + pa |= token & ((1ul << hugepage_shift) - 1); + } This patch fixes the virt -> phys translation in eeh_token_to_phys() function. $ cat /sys/kernel/debug/powerpc/eeh_address_cache mem addr range [0x0000040080000000-0x00000400807fffff]: 0030:01:00.1 mem addr range [0x0000040080800000-0x0000040080ffffff]: 0030:01:00.1 mem addr range [0x0000040081000000-0x00000400817fffff]: 0030:01:00.0 mem addr range [0x0000040081800000-0x0000040081ffffff]: 0030:01:00.0 mem addr range [0x0000040082000000-0x000004008207ffff]: 0030:01:00.1 mem addr range [0x0000040082080000-0x00000400820fffff]: 0030:01:00.0 mem addr range [0x0000040082100000-0x000004008210ffff]: 0030:01:00.1 mem addr range [0x0000040082110000-0x000004008211ffff]: 0030:01:00.0 Above is the list of cached io address ranges of pci 0030:01:00..

Currently Linux will only try using 3 of the 8 available options: 4K, 64K and 16M. According to LoPAR, Hypervisor may also offer 32M, 64M, 128M, 256M and 16G. Enabling bigger pages would be interesting for direct mapping systems with a lot of RAM, while using less TCE entries.

That caller calls it when PageCompound() is true, so bugging on !PageCompound() is useless if we can trust the compiler a little. Remove the BUG_ON(!PageCompound()). The number of elements of a page won't change over time, but GCC doesn't know about it, so it gets the value at every iteration. To avoid that, call compound_nr() outside the loop and save it in a local variable. Whether the page is a HIGHMEM page or not doesn't change over time. But GCC doesn't know it so it does the test on every iteration. Do the test outside the loop. When the page is not a HIGHMEM page, page_address() will fallback on lowmem_page_address(), so call lowmem_page_address() directly and don't suffer the call to page_address() on every iteration.

It is only for HIGHMEM pages that BOOKE needs kmap() and BOOK3S needs flush_dcache_icache_phys(). So make flush_dcache_icache_phys() dependent on CONFIG_HIGHMEM and call it only when it is a HIGHMEM page. We could make flush_dcache_icache_phys() available at all time, but as it is declared NOKPROBE_SYMBOL(), GCC doesn't optimise it out when it is not used.

A few 64e interrupt trap numbers set bit 4. Although they tended to be trivial so it wasn't a real problem[1], it is not the right thing to do, and confusing. [*] E.g., 0x310 hypercall goes to unknown_exception, which prints regs->trap directly so 0x310 will appear fine, and only the syscall interrupt will test norestart, so it won't be confused by 0x310.

In result it breaks CRIU (Checkpoint Restore In Userspace) [1], where CRIU expects that "[vdso]" from /proc/../maps points at ELF/vdso image, rather than at VVAR data page. Laurent made a patch to keep CRIU working (by reading aux vector). But I think it still makes sence to separate two mappings into different VMAs. It will also make ppc64 less "special" for userspace and as a side-bonus will make VVAR page un-writable by debugger (which previously would COW page and can be unexpected). I opportunistically Cc stable on it: I understand that usually such stuff isn't a stable material, but that will allow us in CRIU have one workaround less that is needed just for one release (v5.11) on one platform (ppc64), which we otherwise have to maintain. I wouldn't go as far as to say that the commit 511157ab641e is ABI regression as no other userspace got broken, but I'd really appreciate if it gets backported to v5.11 after v5.12 is released, so as not to complicate already non-simple CRIU-vdso code.

It should be called as below from SSI point of view. P -> S -> E -> P -> S -> E -> ... But, if you used MIXer, below case might happen (2) 1: P -> S ---> E -> ... 2: P ----> S -> ... (1) (3) P(1) setups clock, but E(2) resets it. and starts playback (3). In such case, it will reports "SSI parent/child should use same rate". rsnd_ssi_master_clk_start() which is the main function at (P) was called from rsnd_ssi_init() (= S) before, but was moved by below patch to rsnd_soc_dai_prepare() (= P) to avoid using clk_get_rate() which shouldn't be used under atomic context. commit 4d230d1271064 ("ASoC: rsnd: fixup not to call clk_get/set under non-atomic") Because of above patch, rsnd_ssi_master_clk_start() is now called at (P) which is for non atomic context. But (P) is assuming that spin lock is *not* used. One issue now is rsnd_ssi_master_clk_start() is checking ssi->xxx which should be protected by spin lock. After above patch, adg.c had below patch for other reasons. commit 06e8f5c842f2d ("ASoC: rsnd: don't call clk_get_rate() under atomic context") clk_get_rate() is used at probe() timing by this patch. In other words, rsnd_ssi_master_clk_start() is no longer using clk_get_rate() any more. This means we can call it from rsnd_ssi_init() (= S) again which is protected by spin lock. This patch re-move it to under spin lock, and solves 1. checking ssi->xxx without spin lock issue. 2. clk setting / device start / device stop race condition. Reported-by: Linh Phung T. Y.

The HW parameters are changed based on the codec DAI of the stream. The earlier approach to get snd_soc_dpcm was using container_of() macro on snd_pcm_hw_params. The structures have been modified over time and snd_soc_dpcm does not have snd_pcm_hw_params as a reference but as a copy. This causes the current driver to crash when used. This patch changes the way snd_soc_dpcm is extracted. snd_soc_pcm_runtime holds 2 dpcm instances (one for playback and one for capture). 2 codecs on the SSP are dmic (capture) and speakers (playback). Based on the stream direction, snd_soc_dpcm is extracted from snd_soc_pcm_runtime. Tested for all use cases of the driver.

Make use of this interrupt to drive a state machine which allows the next part of a transfer to happen as soon as the interrupt is received. This is particularly helpful with SMBUS devices like the LM81 which will timeout if we take too long between bytes in a transfer.

The %llu will consume the "0" in "0x" of your input, and the hex value you think you're entering will always be 0. That is, a valid hex value can never be consumed. On the other hand, just entering a hex number without leading 0x will either be scanned as a string and not match, for instance FAB123, or the leading decimal portion is scanned as the %llu, for instance 123FAB will be scanned as 123, which is not correct. Thus remove the first %llu scan and leave only the %llx scan, removing the leading 0x since %llx can scan either. Addresses are usually always hex values, so this suffices.

The "bad_page_cnt_threshold" is a dynamically computed value. It depends on three things: the VRAM size; the size of the EEPROM (or the size allocated to the RAS table therein); and the "bad_page_threshold" module parameter. It is a dynamically computed value, when the amdgpu module is run, on which further parameters and logic depend, and as such it is helpful to see the dynamically computed value in debugfs.

There, the value modification itself was exclusive and protected via a write semaphore, hence it's at most concurrent reads and evaluations before the increment. Since it's only about the soft-limit to avoid the exhausting memory usage, one-off isn't a big problem at all. Meanwhile, the relevant code has been largely modified recently, and now card->user_ctl_count was replaced with card->user_ctl_alloc_size, and a few more places were added to access this field. And, in this new code, it turned out to be more serious: the modifications are scattered in various places, and a few of them are without protection. It implies that it may lead to an inconsistent value by racy accesses. For addressing it, this patch extends the range covered by the card->controls_rwsem write lock at snd_ctl_elem_add() so that the all code paths that modify and refer to card->user_ctl_alloc_size are protected by the rwsem properly. The patch adds also comments in a couple of functions to indicate that they are under the rwsem lock.

These codecs advertise a 4-level microphone input boost amplifier on pin 0x19, but the highest two boost settings do not work correctly, and produce only low analog noise that does not seem to contain any discernible signal. There is an existing fixup for this exact problem but for a different PCI subsystem ID, so we re-use that logic. Changing the boost level also triggers a DC spike in the input signal that bleeds off over about a second and overwhelms any input during that time. Thankfully, the existing fixup has the side effect of making the boost control show up in userspace as a mute/unmute switch, and this keeps (e.g.) PulseAudio from fiddling with it during normal input volume adjustments. Finally, the NUC hardware has built-in inverted stereo mics. This patch also enables the usual fixup for this so the two channels cancel noise instead of the actual signal.

Both FE / BE uses dummy-DAI. FE: CPU <-> dummy-DAI BE: dummy-DAI <-> Codec One note is that we can use .be_hw_params_fixup in DPCM case. This means BE settings might be fixuped/updated by FE. This feature is used for example on MIXer case. It can be happen not only for rate, but for channels/sample_bits too. Because of these reasons, below issue happen on Generation-1 / Generation-3, if... 1) Sound Card used DPCM 2) It exchanges rate to 48kHz by using .be_hw_params_fixup() 3) Codec had symmetric_rate = 1 I didn't confirm, but maybe same things happen if it exchanged channels/sample_bits at Generation-1/2/3 too. # aplay 44100.wav # aplay 44100.wav => [kernel] be.ak4613-hifi: ASoC: unmatched rate symmetry: snd-soc-dummy-dai:44100 - soc_pcm_params_symmetry:48000 [kernel] be.ak4613-hifi: ASoC: hw_params BE failed -22 [kernel] fe.rsnd-dai.0: ASoC: hw_params BE failed -22 aplay: set_params:1407: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 44100 PERIOD_TIME: (23219 23220) PERIOD_SIZE: 1024 PERIOD_BYTES: 4096 PERIODS: 4 BUFFER_TIME: (92879 92880) BUFFER_SIZE: 4096 BUFFER_BYTES: 16384 TICK_TIME: 0 soc_pcm_params_symmetry() checks by below if (symmetry) for_each_rtd_cpu_dais(rtd, i, cpu_dai) if (cpu_dai->xxx && cpu_dai->xxx != d.xxx) { dev_err(rtd->dev, "..."); return -EINVAL; } Because of above reason 3) (= Codec had symmetric_rate = 1) BE can't ignore "if (symmetric)". At 1st aplay, soc_pcm_params_symmetry() ignores it, because dummy-DAI->rate is 0. After this check, each DAI sets/keep settings. In above sample case, BE gets 48000 and FE gets 44100, and it happen BE -> FE order. Because DPCM is sharing *same* dummy-DAI, dummy-DAI sets as 48000 by BE, and is overwrote by 44100 by FE.

DP/HDMI receiver connected 3. system resumed 4. HDA controller resumed, but card->deferred_resume_work not complete 5. acomp eld_notify callback 6. eld_notify ignored as power state is not CTL_POWER_D0 7. HDA resume deferred work completed, power state set to CTL_POWER_D0 This results in losing the notification, and the jack state reported to user-space is not correct. The check on step 6 was added in commit 8ae743e82f0b ("ALSA: hda - Skip ELD notification during system suspend"). It would seem with the deferred resume logic in ASoC core, this check is not safe. Fix the issue by modifying the check to use "dev.power.power_state.event" instead of ALSA specific card power state variable.

For that, the XIVE driver queries the chip identifier from the "ibm,chip-id" property and compares it to a 'src_chip' field identifying the chip of a source. This information is only available on the PowerNV platform, 'src_chip' being assigned to XIVE_INVALID_CHIP_ID under pSeries. The "ibm,chip-id" property is also not available on all platforms. It was first introduced on PowerNV and later, under QEMU for pSeries/KVM. However, the property is not part of PAPR and does not exist under pSeries/PowerVM. Assign 'chip_id' to XIVE_INVALID_CHIP_ID by default and let the PowerNV platform override the value with the "ibm,chip-id" property.

The above commit helped to reduce boot time on Large Systems for example 4096 vCPU single socket QEMU instance. PAPR is silent on having more than one socket within a NUMA node. cpu_core_mask and cpu_cpu_mask for any CPU would be same unless the number of sockets is different from the number of NUMA nodes. One option is to reintroduce cpu_core_mask but use a slightly different method to arrive at the cpu_core_mask. Previously each CPU's chip-id would be compared with all other CPU's chip-id to verify if both the CPUs were related at the chip level. Now if a CPU 'A' is found related / (unrelated) to another CPU 'B', all the thread siblings of 'A' and thread siblings of 'B' are automatically marked as related / (unrelated). Also if a platform doesn't support ibm,chip-id property, i.e its cpu_to_chip_id returns -1, cpu_core_map holds a copy of cpu_cpu_mask().

Instead, a new LPCR[HAIL] bit is defined which behaves like AIL=3 for HV interrupts when set. Set HAIL on bare metal to give us mmu-on interrupts and improve performance. This also fixes an scv bug: we don't implement scv real mode (AIL=0) vectors because they are at an inconvenient location, so we just disable scv support when AIL can not be set. However powernv assumes that LPCR[AIL] will enable AIL mode so it enables scv support despite HV interrupts being AIL=0, which causes scv interrupts to go off into the weeds.

Recently, Geraldo discovered that the device actually works if you skip the generic matching of the sync EPs for the capture stream. That is, we should apply the implicit feedback setup for the playback like other similar devices, while we need to return 1 from audioformat_capture_quirk() so that no further matching will be done. And, later on, Olivia reported later that the fiddling with the capture quirk alone doesn't suffice for the test with speaker-test program. This seems to be a similar case like the recently fixed BOSS devices. Indeed, the problem could be addressed by setting playback_first flag, which indicates that the playback URBs have to be sent out at first even in the implicit feedback mode. This patch implements the application of the implicit feedback to Pioneer devices as described in the above. The former skip_pioneer_sync_ep() was dropped, and instead we provide is_pioneer_implicit_fb() to check the Pioneer devices that need the implicit feedback. In the audioformat_implicit_fb_quirk(), simply apply the implicit fb for playback and set chip->playback_first flag if matching, and in audioformat_capture_quirk()(), it returns 1 for skipping the generic EP sync handling.

This gives us an opportunity to use this behavior to signal the hypervisor layer when an error during device removal happens, allowing it to do a proper error handling, while not breaking QEMU/phyp implementations that don't have this support. This patch introduces this idea by unisolating all CPU DRCs that failed to be removed by dlpar_cpu_remove_by_index(), when handling the PSERIES_HP_ELOG_ID_DRC_INDEX event. This is being done for this event only because its the only CPU removal event QEMU uses, and there's no need at this moment to add this mechanism for phyp only code.

From af31fd0c9107e400a8eb89d0eafb40bb78802f79 Mon Sep 17 00:00:00 2001 From: Athira Rajeev Date: Mon, 22 Mar 2021 10:57:23 -0400 Subject: [PATCH 1084/1426] powerpc/perf: Expose processor pipeline stage cycles using PERF_SAMPLE_WEIGHT_STRUCT Performance Monitoring Unit (PMU) registers in powerpc provides information on cycles elapsed between different stages in the pipeline. This can be used for application tuning. On ISA v3.1 platform, this information is exposed by sampling registers. Patch adds kernel support to capture two of the cycle counters as part of perf sample using the sample type: PERF_SAMPLE_WEIGHT_STRUCT. The power PMU function 'get_mem_weight' currently uses 64 bit weight field of perf_sample_data to capture memory latency. But following the introduction of PERF_SAMPLE_WEIGHT_TYPE, weight field could contain 64-bit or 32-bit value depending on the architexture support for PERF_SAMPLE_WEIGHT_STRUCT. Patches uses WEIGHT_STRUCT to expose the pipeline stage cycles info. Hence update the ppmu functions to work for 64-bit and 32-bit weight values. If the sample type is PERF_SAMPLE_WEIGHT, use the 64-bit weight field. if the sample type is PERF_SAMPLE_WEIGHT_STRUCT, memory subsystem latency is stored in the low 32bits of perf_sample_weight structure. Also for CPU_FTR_ARCH_31, capture the two cycle counter information in two 16 bit fields of perf_sample_weight structure.

The root cause seems to be that KVM PR is creating kernel mappings that don't use the correct key, since we switched to using key 3. We have a helper for adding the right key value, however it's designed to take a pteflags variable, which the KVM code doesn't have.

It is used on 8xx to write to SPRN_NRI, SPRN_EID and SPRN_EIE. Writing any value to one of those will play with MSR EE and MSR RI regardless of that value. r0 is used many places in the generated code and using r0 for that creates an unnecessary dependency of this instruction with preceding ones using r0 in a few places in vmlinux. r2 is most likely the most stable register as it contains the pointer to 'current'. Using r2 instead of r0 avoids that unnecessary dependency.

If one day it is really needed, we can give it a new name more in line with today's naming, and implement it using get_user_inst() Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/5f6f82572242a59bfee1e19a71194d8f7ef5fca4.1618405715.git.christophe.leroy@csgroup.eu --- arch/powerpc/include/asm/inst.h | 3 --- arch/powerpc/lib/inst.c | 31 ------------------------------- 2 files changed, 34 deletions(-) diff --git a/arch/powerpc/include/asm/inst.h b/arch/powerpc/include/asm/inst.h index 9646c63f7420..b7709470e8e9 100644 --- a/arch/powerpc/include/asm/inst.h +++ b/arch/powerpc/include/asm/inst.h @@ -176,9 +176,6 @@ static inline char *__ppc_inst_as_str(char str[PPC_INST_STR_LEN], struct ppc_ins __str; \ }) -int probe_user_read_inst(struct ppc_inst *inst, - struct ppc_inst __user *nip); - int probe_kernel_read_inst(struct ppc_inst *inst, struct ppc_inst *src); diff --git a/arch/powerpc/lib/inst.c b/arch/powerpc/lib/inst.c index 9cc17eb62462..c57b3548de37 100644 --- a/arch/powerpc/lib/inst.c +++ b/arch/powerpc/lib/inst.c @@ -9,24 +9,6 @@ #include #ifdef CONFIG_PPC64 -int probe_user_read_inst(struct ppc_inst *inst, - struct ppc_inst __user *nip) -{ - unsigned int val, suffix; - int err; - - err = copy_from_user_nofault(&val, nip, sizeof(val)); - if (err) - return err; - if (get_op(val) == OP_PREFIX) { - err = copy_from_user_nofault(&suffix, (void __user *)nip + 4, 4); - *inst = ppc_inst_prefix(val, suffix); - } else { - *inst = ppc_inst(val); - } - return err; -} - int probe_kernel_read_inst(struct ppc_inst *inst, struct ppc_inst *src) { @@ -45,19 +27,6 @@ int probe_kernel_read_inst(struct ppc_inst *inst, return err; } #else /* !CONFIG_PPC64 */ -int probe_user_read_inst(struct ppc_inst *inst, - struct ppc_inst __user *nip) -{ - unsigned int val; - int err; - - err = copy_from_user_nofault(&val, nip, sizeof(val)); - if (!err) - *inst = ppc_inst(val); - - return err; -} - int probe_kernel_read_inst(struct ppc_inst *inst, struct ppc_inst *src) { From 6449078d50111c839bb7156c3b99b9def80eed42 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Wed, 14 Apr 2021 13:08:41 +0000 Subject: [PATCH 1145/1426] powerpc: Make probe_kernel_read_inst() common to PPC32 and PPC64 We have two independant versions of probe_kernel_read_inst(), one for PPC32 and one for PPC64.

Currently, in the mainline, no other devicetree out there is using the "lcd-18bit-tft" ABI, so we should be able to replace it safely. 2.In the JZ4725B part, adjust the location of the LCD pins related code to keep them consistent with the style of other parts. 3.In the JZ4760 part, add the missing comma and adjust element order in "jz4760_lcd_special_pins[]", keep them in the order of CLS/SPL/PS/REV like other "lcd_special_pins" arrays. And adjust the location of the "jz4760_lcd_generic" related code to keep them consistent with the style of other parts. 4.In the JZ4770 part, remove pointless "lcd-no-pins", add the missing "lcd-16bit", "lcd-18bit", "lcd-special", "lcd-generic". 5.In the X1000 part and the X1500 part, remove pointless "lcd-no-pins". 6.In the X1830 part, replace "lcd-rgb-18bit" with "lcd-tft-8bit" and "lcd-tft-24bit", because of the description of the TRANS_CONFIG.MODE register bits in the PM manual of the X1830, shows that the X1830 only supppots 24bit mode and 8bit mode for tft interface, only 18 pins in the GPIO table are because of the data[17:16], the data[9:8], and the data[1:0] has not been connected. And according to the description, the two interfaces supported by X1830 are respectively referred to as "TFT interface" and "SLCD interface", so the "lcd-rgb-xxx" is replaced with "lcd-tft-xxx" to avoid confusion.

This has always been a contiguous array allocated at either the boot time or when a passed through device is returned to the host OS. The it_map memory is allocated by alloc_pages() which allocates contiguous physical memory. Such allocation method occasionally creates a problem when there is no big chunk of memory available (no free memory or too fragmented). On powernv/ioda2 the default DMA window requires 16MB for it_map. This replaces alloc_pages_node() with vzalloc_node() which allocates contiguous block but in virtual memory. This should reduce changes of failure but should not cause other behavioral changes as it_map is only used by the kernel's DMA hooks/api when MMU is on.

However the powernv platform allocates it_map after a device is returned to the host OS after being passed through and this happens long after the host OS booted. It is quite possible to trigger the it_map allocation panic() and kill the host even though it is not necessary - the host OS can still use the DMA bypass mode (requires a tiny fraction of it_map's memory) and even if that fails, the host OS is runnnable as it was without the device for which allocating it_map causes the panic. Instead of immediately crashing in a powernv/ioda2 system, this prints an error and continues. All other platforms still call panic().

The recent commit d86f43b17ed4 ("ALSA: usb-audio: Add support for many Roland devices' implicit feedback quirks") tried to add such quirk entries manually in the lists, but this turned out to be too many and error-prone, hence it was reverted again. This patch is another attempt to cover those missing Roland/BOSS devices but in a more generic way. It matches the devices with the vendor ID 0x0582, and checks whether they are with both ASYNC sync types or ASYNC is only for capture device. In the former case, it's the device with the implicit feedback mode, and applies accordingly. In both cases, the capture stream requires always the full-duplex mode, and we apply the known capture quirk for that, too. Basically the already existing BOSS device quirk entries become redundant after this generic matching, so those are removed. Although the capture_implicit_fb_quirks[] table became empty and superfluous, I keep it for now, so that people can put a special device easily at any time later again.

When IOMMU_PAGE_SIZE < PAGE_SIZE, this behavior may cause unnecessary TCEs to be created for mapping the whole system page. Example: - PAGE_SIZE = 64k, IOMMU_PAGE_SIZE() = 4k - iommu_alloc_coherent() is called for 128 bytes - 1 system page (64k) is allocated - 16 IOMMU pages (16 x 4k) are allocated (16 TCEs used) It would be enough to use a single TCE for this, so 15 TCEs are wasted in the process. Update iommu_*_coherent() to make sure the size alignment happens only for IOMMU_PAGE_SIZE() before calling iommu_alloc() and iommu_free(). Also, on iommu_range_alloc(), replace ALIGN(n, 1 << tbl->it_page_shift) with IOMMU_PAGE_ALIGN(n, tbl), which is easier to read and does the same.

This turned out to cause a regression, however, when full-duplex streams were running and only a capture was stopped. Because of the above clearance of ep->sync_sink pointer, no more feedback is done, hence the playback will stall. This patch fixes the ep->sync_sink clearance to be done only after all endpoints are released, for addressing the regression.

This was previously silently ignored, but is now caught by the aforementioned commit. The culprit is ia64's node_possible_map which remains unchanged from its initialization value of NODE_MASK_ALL. In John's case, the machine doesn't have any SRAT nor SLIT table, but AIUI the possible map remains untouched regardless of what ACPI tables end up being parsed. Thus, !online && possible nodes remain with a bogus distance of 0 (distances \in [0, 9] are "reserved and have no meaning" as per the ACPI spec). Follow x86 / drivers/base/arch_numa's example and set the possible map to the parsed map, which in this case seems to be the online map.

All section headers are already freed after module is laoded successfully. To keep symbolizer working the change stores ".opd" address and size after module is relocated to a new place and before section headers are discarded. To make similar errors less obscure module_finalize() now zeroes out all variables relevant to module loading only.

The negative error code is first cast to u32 so it becomes a high positive and then cast to long where it's still a positive. We could fix this by declaring "ret" as a ssize_t but let's just get rid of the ternaries instead.

I dug deep into the softlockup watchdog history when time permitted this year. And reworked the patchset that fixed timestamps and cleaned up the code[2]. I split it into very small steps and did even more code clean up. The result looks quite strightforward and I am pretty confident with the changes. [1] v2: https://lore.kernel.org/r/20201210160038.31441-1-pmladek@suse.com [2] v1: https://lore.kernel.org/r/20191024114928.15377-1-pmladek@suse.com This patch (of 6): There are many touch_*watchdog() functions. They are called in situations where the watchdog could report false positives or create unnecessary noise. For example, when CPU is entering idle mode, a virtual machine is stopped, or a lot of messages are printed in the atomic context. These functions set SOFTLOCKUP_RESET instead of a real timestamp. It allows to call them even in a context where jiffies might be outdated. For example, in an atomic context. The real timestamp is set by __touch_watchdog() that is called from the watchdog timer callback. Rename this callback to update_touch_ts(). It better describes the effect and clearly distinguish is from the other touch_*watchdog() functions. Another motivation is that two timestamps are going to be used. One will be used for the total softlockup time. The other will be used to measure time since the last report. The new function name will help to distinguish which timestamp is being updated.

When it happens, the softlockup debug messages are printed in regular intervals defined by get_softlockup_thresh(). There is a mystery. The repeated message is printed after the full interval that is defined by get_softlockup_thresh(). But the timer callback is called more often as defined by sample_period. The code looks like the soflockup should get reported in every sample_period when it was once behind the thresh. It works only by chance. The watchdog is touched when printing the stall report, for example, in printk_stack_address(). Make the behavior clear and predictable by explicitly updating the timestamp in watchdog_timer_fn() when the report gets printed.

It was added by the commit 58687acba59266735ad ("lockup_detector: Combine nmi_watchdog and softlockup detector"). The purpose is not completely clear. There are the following clues. They describe the situation how it looked after the above mentioned commit: 1. The variable was checked with a comment "only warn once". 2. The variable was set when softlockup was reported. It was cleared only when the CPU was not longer in the softlockup state. 3. watchdog_touch_ts was not explicitly updated when the softlockup was reported. Without this variable, the report would normally be printed again during every following watchdog_timer_fn() invocation. The logic has got even more tangled up by the commit ed235875e2ca98 ("kernel/watchdog.c: print traces for all cpus on lockup detection"). After this commit, soft_watchdog_warn is set only when softlockup_all_cpu_backtrace is enabled. But multiple reports from all CPUs are prevented by a new variable soft_lockup_nmi_warn. Conclusion: The variable probably never worked as intended. In each case, it has not worked last many years because the softlockup was reported repeatedly after the full period defined by watchdog_thresh. The reason is that watchdog gets touched in many known slow paths, for example, in printk_stack_address(). This code is called also when printing the softlockup report. It means that the watchdog timestamp gets updated after each report. Solution: Simply remove the logic. People want the periodic report anyway.

It solved a problem when the watchdog was touched in an atomic context, the timer callback was proceed right after releasing interrupts, and the local clock has not been updated yet. In this case, sched_clock_tick() was called in watchdog_timer_fn() before updating the timer. So far so good. Later commit 5d1c0f4a80a6 ("watchdog: add check for suspended vm in softlockup detector") added two kvm_check_and_clear_guest_paused() calls. They touch the watchdog when the guest has been sleeping. The code makes my head spin around. Scenario 1: + guest did sleep: + PVCLOCK_GUEST_STOPPED is set + 1st watchdog_timer_fn() invocation: + the watchdog is not touched yet + is_softlockup() returns too big delay + kvm_check_and_clear_guest_paused(): + clear PVCLOCK_GUEST_STOPPED + call touch_softlockup_watchdog_sync() + set SOFTLOCKUP_DELAY_REPORT + set softlockup_touch_sync + return from the timer callback + 2nd watchdog_timer_fn() invocation: + call sched_clock_tick() even though it is not needed. The timer callback was invoked again only because the clock has already been updated in the meantime. + call kvm_check_and_clear_guest_paused() that does nothing because PVCLOCK_GUEST_STOPPED has been cleared already. + call update_report_ts() and return. This is fine. Except that sched_clock_tick() might allow to set it already during the 1st invocation. Scenario 2: + guest did sleep + 1st watchdog_timer_fn() invocation + same as in 1st scenario + guest did sleep again: + set PVCLOCK_GUEST_STOPPED again + 2nd watchdog_timer_fn() invocation + SOFTLOCKUP_DELAY_REPORT is set from 1st invocation + call sched_clock_tick() + call kvm_check_and_clear_guest_paused() + clear PVCLOCK_GUEST_STOPPED + call touch_softlockup_watchdog_sync() + set SOFTLOCKUP_DELAY_REPORT + set softlockup_touch_sync + call update_report_ts() (set real timestamp immediately) + return from the timer callback + 3rd watchdog_timer_fn() invocation + timestamp is set from 2nd invocation + softlockup_touch_sync is set but not checked because the real timestamp is already set Make the code more straightforward: 1. Always call kvm_check_and_clear_guest_paused() at the very beginning to handle PVCLOCK_GUEST_STOPPED. It touches the watchdog when the quest did sleep. 2. Handle the situation when the watchdog has been touched (SOFTLOCKUP_DELAY_REPORT is set). Call sched_clock_tick() when touch_*sync() variant was used. It makes sure that the timestamp will be up to date even when it has been touched in atomic context or quest did sleep. As a result, kvm_check_and_clear_guest_paused() is called on a single location. And the right timestamp is always set when returning from the timer callback.

The static key is enabled when slub_debug boot parameter is passed, or CONFIG_SLUB_DEBUG_ON enabled. However, some caches might be created with one or more debugging flags explicitly passed to kmem_cache_create(), and the commit missed this. Thus the debugging functionality would not be actually performed for these caches unless the static key gets enabled by boot param or config. This patch fixes it by checking for debugging flags passed to kmem_cache_create() and enabling the static key accordingly. Note such explicit debugging flags should not be used outside of debugging and testing as they will now enable the static key globally. btrfs_init_cachep() creates a cache with SLAB_RED_ZONE but that's a mistake that's being corrected [1]. rcu_torture_stats() creates a cache with SLAB_STORE_USER, but that is a testing module so it's OK and will start working as intended after this patch. Also note that in case of backports to kernels before v5.12 that don't have 59450bbc12be ("mm, slab, slub: stop taking cpu hotplug lock"), static_branch_enable_cpuslocked() should be used.

An internal workload complained because it was using too much CPU, and when I took a look, we had a lot of io_uring workers going to town. For an async buffered read like workload, I am normally expecting _zero_ offloads to a worker thread, but this one had tons of them. I'd drop caches and things would look good again, but then a minute later we'd regress back to using workers. Turns out that every minute something was reading parts of the device, which would add page cache for that inode. I put patches like these in for our kernel, and the problem was solved. Don't -EAGAIN IOCB_NOWAIT dio reads just because we have page cache entries for the given range. This causes unnecessary work from the callers side, when the IO could have been issued totally fine without blocking on writeback when there is none. This patch (of 3): For O_DIRECT reads/writes, we check if we need to issue a call to filemap_write_and_wait_range() to issue and/or wait for writeback for any page in the given range. The existing mechanism just checks for a page in the range, which is suboptimal for IOCB_NOWAIT as we'll fallback to the slow path (and needing retry) if there's just a clean page cache page in the range. Provide filemap_range_needs_writeback() which tries a little harder to check if we actually need to issue and/or wait for writeback in the range.

If the I/O completed with an error, this check would cause us to retry the I/O if the page were truncated before we woke up. There is no need to retry the I/O; the I/O to fill the page failed, so we can legitimately just return -EIO. This code was originally added by commit 56f0d5fe6851 ("[PATCH] readpage-vs-invalidate fix") in 2005 (this commit ID is from the linux-fullhistory tree; it is also commit ba1f08f14b52 in tglx-history). At the time, truncate_complete_page() called ClearPageUptodate(), and so this was fixing a real bug. In 2008, commit 84209e02de48 ("mm: dont clear PG_uptodate on truncate/invalidate") removed the call to ClearPageUptodate, and this check has been unnecessary ever since. It doesn't do any real harm, but there's no need to keep it.

Since commit 073861ed77b6 ("mm: fix VM_BUG_ON(PageTail) and BUG_ON(PageWriteback)") test_clear_page_writeback() is called with an explicit reference on the page, and this dance is no longer needed. Use unlock_page_memcg() and dec_lruvec_page_state() directly. This removes the last user of the lock_page_memcg() return value, change it to void. Touch up the comments in there as well. This also removes the last extern user of __unlock_page_memcg(), make it static. Further, it removes the last user of dec_lruvec_state(), delete it, along with a few other unused helpers.

This series improves page unpinning, with an eye on improving MR deregistration for big swaths of memory (which is bound by the page unpining), particularly: 1) Decrement the head page by @ntails and thus reducing a lot the number of atomic operations per compound page. This is done by comparing individual tail pages heads, and counting number of consecutive tails on which they match heads and based on that update head page refcount. Should have a visible improvement in all page (un)pinners which use compound pages 2) Introducing a new API for unpinning page ranges (to avoid the trick in the previous item and be based on math), and use that in RDMA ib_mem_release (used for mr deregistration). Performance improvements: unpin_user_pages() for hugetlbfs and THP improves ~3x (through gup_test) and RDMA MR dereg improves ~4.5x with the new API. See patches 2 and 4 for those. This patch (of 4): Add a helper that iterates over head pages in a list of pages. It essentially counts the tails until the next page to process has a different head that the current. This is going to be used by unpin_user_pages() family of functions, to batch the head page refcount updates once for all passed consecutive tail pages.

By doing that we have lost a certain precision because those pages might live in different NUMA nodes. In the end NR_KERNEL_STACK_KB exported to the userspace might be over estimated on some nodes while underestimated on others. But this is not a real world problem, just a problem found by reading the code. So there is no actual data to showing how much impact it has on users. This doesn't impose any real problem to correctnes of the kernel behavior as the counter is not used for any internal processing but it can cause some confusion to the userspace. Address the problem by accounting each vmalloc backing page to its own node.

The reason was that the __GFP_NOFAIL callers will not enter aync oom synchronization path and will keep the task marked as in memcg oom. At that time the tasks marked in memcg oom can bypass the memcg limits and the oom synchronization would have happened later in the later userspace triggered page fault. Thus letting the task marked as under memcg oom bypass the memcg limit for arbitrary time. With the synchronous memcg oom-killer (commit 29ef680ae7c21 ("memcg, oom: move out_of_memory back to the charge path")) and not letting the task marked under memcg oom to bypass the memcg limits (commit 1f14c1ac19aa4 ("mm: memcg: do not allow task about to OOM kill to bypass the limit")), we can again allow __GFP_NOFAIL allocations to trigger memcg oom-kill. This will make memcg oom behavior closer to page allocator oom behavior.

This series converts memcg stats tracking to the streamlined rstat infrastructure provided by the cgroup core code. rstat is already used by the CPU controller and the IO controller. This change is motivated by recent accuracy problems in memcg's custom stats code, as well as the benefits of sharing common infra with other controllers. The current memcg implementation does batched tree aggregation on the write side: local stat changes are cached in per-cpu counters, which are then propagated upward in batches when a threshold (32 pages) is exceeded. This is cheap, but the error introduced by the lazy upward propagation adds up: 32 pages times CPUs times cgroups in the subtree. We've had complaints from service owners that the stats do not reliably track and react to allocation behavior as expected, sometimes swallowing the results of entire test applications. The original memcg stat implementation used to do tree aggregation exclusively on the read side: local stats would only ever be tracked in per-cpu counters, and a memory.stat read would iterate the entire subtree and sum those counters up. This didn't keep up with the times: - Cgroup trees are much bigger now. We switched to lazily-freed cgroups, where deleted groups would hang around until their remaining page cache has been reclaimed. This can result in large subtrees that are expensive to walk, while most of the groups are idle and their statistics don't change much anymore. - Automated monitoring increased. With the proliferation of userspace oom killing, proactive reclaim, and higher-resolution logging of workload trends in general, top-level stat files are polled at least once a second in many deployments. - The lifetime of cgroups got shorter. Where most cgroup setups in the past would have a few large policy-oriented cgroups for everything running on the system, newer cgroup deployments tend to create one group per application - which gets deleted again as the processes exit. An aggregation scheme that doesn't retain child data inside the parents loses event history of the subtree. Rstat addresses all three of those concerns through intelligent, persistent read-side aggregation. As statistics change at the local level, rstat tracks - on a per-cpu basis - only those parts of a subtree that have changes pending and require aggregation. The actual aggregation occurs on the colder read side - which can now skip over (potentially large) numbers of recently idle cgroups. === The test_kmem cgroup selftest is currently failing due to excessive cumulative vmstat drift from 100 subgroups: ok 1 test_kmem_basic memory.current = 8810496 slab + anon + file + kernel_stack = 17074568 slab = 6101384 anon = 946176 file = 0 kernel_stack = 10027008 not ok 2 test_kmem_memcg_deletion ok 3 test_kmem_proc_kpagecgroup ok 4 test_kmem_kernel_stacks ok 5 test_kmem_dead_cgroups ok 6 test_percpu_basic As you can see, memory.stat items far exceed memory.current. The kernel stack alone is bigger than all of charged memory. That's because the memory of the test has been uncharged from memory.current, but the negative vmstat deltas are still sitting in the percpu caches. The test at this time isn't even counting percpu, pagetables etc. yet, which would further contribute to the error. The last patch in the series updates the test to include them - as well as reduces the vmstat tolerances in general to only expect page_counter batching. With all patches applied, the (now more stringent) test succeeds: ok 1 test_kmem_basic ok 2 test_kmem_memcg_deletion ok 3 test_kmem_proc_kpagecgroup ok 4 test_kmem_kernel_stacks ok 5 test_kmem_dead_cgroups ok 6 test_percpu_basic === A kernel build test confirms that overhead is comparable.

Flush the CPU that is actually going away. Also simplify the code a bit by using mod_memcg_state() and count_memcg_events() instead of open-coding the upward flush - this is comparable to how vmstat.c handles hotunplug flushing.

In order to replace memcg's private stats infrastructure - used in both cgroup1 and cgroup2 - with rstat, the latter needs to support cgroup1. The initialization and destruction callbacks for regular cgroups are already in place. Remove the cgroup_on_dfl() guards to handle cgroup1. The initialization of the root cgroup is currently hardcoded to only handle cgrp_dfl_root.cgrp. Move those callbacks to cgroup_setup_root() and cgroup_destroy_root() to handle the default root as well as the various cgroup1 roots we may set up during mounting. The linking of css to cgroups happens in code shared between cgroup1 and cgroup2 as well. Simply remove the cgroup_on_dfl() guard. Linkage of the root css to the root cgroup is a bit trickier: per default, the root css of a subsystem controller belongs to the default hierarchy (i.e. the cgroup2 root). When a controller is mounted in its cgroup1 version, the root css is stolen and moved to the cgroup1 root; on unmount, the css moves back to the default hierarchy. Annotate rebind_subsystems() to move the root css linkage along between roots.

This optimization is currently implemented inside the generic rstat code, which doesn't track the root cgroup and doesn't invoke the subsystem flush callbacks on it. However, the memory controller cannot do this optimization, because cgroup1 breaks out memory specifically for the local level, including at the root level. In preparation for the memory controller switching to rstat, move the optimization from rstat core to the controllers. Afterwards, rstat will always track the root cgroup for changes and invoke the subsystem callbacks on it; and it's up to the subsystem to special-case and skip aggregation of the root cgroup if it can source this information through other, cheaper means. This is the case for the io controller and the cgroup base stats. In their respective flush callbacks, check whether the parent is the root cgroup, and if so, skip the unnecessary upward propagation. The extra cost of tracking the root cgroup is negligible: on stat changes, we actually remove a branch that checks for the root. The queueing for a flush touches only per-cpu data, and only the first stat change since a flush requires a (per-cpu) lock.

The current implementation does batched upward propagation from the write side (i.e. as stats change). The per-cpu batches introduce an error, which is multiplied by the number of subgroups in a tree. In systems with many CPUs and sizable cgroup trees, the error can be large enough to confuse users (e.g. 32 batch pages * 32 CPUs * 32 subgroups results in an error of up to 128M per stat item). This can entirely swallow allocation bursts inside a workload that the user is expecting to see reflected in the statistics. In the past, we've done read-side aggregation, where a memory.stat read would have to walk the entire subtree and add up per-cpu counts. This became problematic with lazily-freed cgroups: we could have large subtrees where most cgroups were entirely idle. Hence the switch to change-driven upward propagation. Unfortunately, it needed to trade accuracy for speed due to the write side being so hot. Rstat combines the best of both worlds: from the write side, it cheaply maintains a queue of cgroups that have pending changes, so that the read side can do selective tree aggregation. This way the reported stats will always be precise and recent as can be, while the aggregation can skip over potentially large numbers of idle cgroups. The way rstat works is that it implements a tree for tracking cgroups with pending local changes, as well as a flush function that walks the tree upwards. The controller then drives this by 1) telling rstat when a local cgroup stat changes (e.g. mod_memcg_state) and 2) when a flush is required to get uptodate hierarchy stats for a given subtree (e.g. when memory.stat is read). The controller also provides a flush callback that is called during the rstat flush walk for each cgroup and aggregates its local per-cpu counters and propagates them upwards. This adds a second vmstats to struct mem_cgroup (MEMCG_NR_STAT + NR_VM_EVENT_ITEMS) to track pending subtree deltas during upward aggregation. It removes 3 words from the per-cpu data. It eliminates memcg_exact_page_state(), since memcg_page_state() is now exact.

This is fine but now we want a per-memcg swapcache stat which is essential for folks who wants to transparently migrate from cgroup v1's memsw to cgroup v2's memory and swap counters. In addition charging a page before exposing it to other parts of the kernel is a step in the right direction. To correctly maintain the per-memcg swapcache stat, this patch has adopted to charge the page before adding it to swapcache. One challenge in this option is the failure case of add_to_swap_cache() on which we need to undo the mem_cgroup_charge(). Specifically undoing mem_cgroup_uncharge_swap() is not simple. To resolve the issue, this patch decouples the charging for swapin pages from mem_cgroup_charge(). Two new functions are introduced, mem_cgroup_swapin_charge_page() for just charging the swapin page and mem_cgroup_swapin_uncharge_swap() for uncharging the swap slot once the page has been successfully added to the swapcache.

Since Roman's series "The new cgroup slab memory controller" applied. All slab objects are charged with the new APIs of obj_cgroup. The new APIs introduce a struct obj_cgroup to charge slab objects. It prevents long-living objects from pinning the original memory cgroup in the memory. But there are still some corner objects (e.g. allocations larger than order-1 page on SLUB) which are not charged with the new APIs. Those objects (include the pages which are allocated from buddy allocator directly) are charged as kmem pages which still hold a reference to the memory cgroup. E.g. We know that the kernel stack is charged as kmem pages because the size of the kernel stack can be greater than 2 pages (e.g. 16KB on x86_64 or arm64). If we create a thread (suppose the thread stack is charged to memory cgroup A) and then move it from memory cgroup A to memory cgroup B. Because the kernel stack of the thread hold a reference to the memory cgroup A. The thread can pin the memory cgroup A in the memory even if we remove the cgroup A. If we want to see this scenario by using the following script. We can see that the system has added 500 dying cgroups (This is not a real world issue, just a script to show that the large kmallocs are charged as kmem pages which can pin the memory cgroup in the memory). #!/bin/bash cat /proc/cgroups | grep memory cd /sys/fs/cgroup/memory echo 1 > memory.move_charge_at_immigrate for i in range{1..500} do mkdir kmem_test echo $$ > kmem_test/cgroup.procs sleep 3600 & echo $$ > cgroup.procs echo `cat kmem_test/cgroup.procs` > cgroup.procs rmdir kmem_test done cat /proc/cgroups | grep memory This patchset aims to make those kmem pages to drop the reference to memory cgroup by using the APIs of obj_cgroup. Finally, we can see that the number of the dying cgroups will not increase if we run the above test script. This patch (of 7): The rcu_read_lock/unlock only can guarantee that the memcg will not be freed, but it cannot guarantee the success of css_get (which is in the refill_stock when cached memcg changed) to memcg. rcu_read_lock() memcg = obj_cgroup_memcg(old) __memcg_kmem_uncharge(memcg) refill_stock(memcg) if (stock->cached != memcg) // css_get can change the ref counter from 0 back to 1. css_get(&memcg->css) rcu_read_unlock() This fix is very like the commit: eefbfa7fd678 ("mm: memcg/slab: fix use after free in obj_cgroup_charge") Fix this by holding a reference to the memcg which is passed to the __memcg_kmem_uncharge() before calling __memcg_kmem_uncharge().

All slab objects are charged via the new APIs of obj_cgroup. The new APIs introduce a struct obj_cgroup to charge slab objects. It prevents long-living objects from pinning the original memory cgroup in the memory. But there are still some corner objects (e.g. allocations larger than order-1 page on SLUB) which are not charged via the new APIs. Those objects (include the pages which are allocated from buddy allocator directly) are charged as kmem pages which still hold a reference to the memory cgroup. We want to reuse the obj_cgroup APIs to charge the kmem pages. If we do that, we should store an object cgroup pointer to page->memcg_data for the kmem pages. Finally, page->memcg_data will have 3 different meanings. 1) For the slab pages, page->memcg_data points to an object cgroups vector. 2) For the kmem pages (exclude the slab pages), page->memcg_data points to an object cgroup. 3) For the user pages (e.g. the LRU pages), page->memcg_data points to a memory cgroup. We do not change the behavior of page_memcg() and page_memcg_rcu(). They are also suitable for LRU pages and kmem pages. Why? Because memory allocations pinning memcgs for a long time - it exists at a larger scale and is causing recurring problems in the real world: page cache doesn't get reclaimed for a long time, or is used by the second, third, fourth, ... instance of the same job that was restarted into a new cgroup every time. Unreclaimable dying cgroups pile up, waste memory, and make page reclaim very inefficient. We can convert LRU pages and most other raw memcg pins to the objcg direction to fix this problem, and then the page->memcg will always point to an object cgroup pointer. At that time, LRU pages and kmem pages will be treated the same. The implementation of page_memcg() will remove the kmem page check. This patch aims to charge the kmem pages by using the new APIs of obj_cgroup. Finally, the page->memcg_data of the kmem page points to an object cgroup. We can use the __page_objcg() to get the object cgroup associated with a kmem page. Or we can use page_memcg() to get the memory cgroup associated with a kmem page, but caller must ensure that the returned memcg won't be released (e.g. acquire the rcu_read_lock or css_set_lock).

This series contains cleanups to remove dead code that handles unaligned cases for 4K and 1GB pages (patch#1 and patch#2) when removing the vemmmap range, and a fix (patch#3) to handle the case when two vmemmap ranges intersect the same PMD. This patch (of 4): remove_pte_table() is prepared to handle the case where either the start or the end of the range is not PAGE aligned. This cannot actually happen: __populate_section_memmap enforces the range to be PMD aligned, so as long as the size of the struct page remains multiple of 8, the vmemmap range will be aligned to PAGE_SIZE. Drop the dead code and place a VM_BUG_ON in vmemmap_{populate,free} to catch nasty cases. Note that the VM_BUG_ON is placed in there because vmemmap_{populate,free= } is the gate of all removing and freeing page tables logic.

In that case, let us keep track where the unused range of the previous memory range begins, so we can compare it with start of the range to be added. If they are equal, we know sections are added consecutively. For that purpose, let us introduce 'unused_pmd_start', which always holds the beginning of the unused memory range. In the case a section does not contiguously follow the previous one, we know we can memset [unused_pmd_start, PMD_BOUNDARY) with PAGE_UNUSE.

Add a function to the core VM to do just that rather than reinventing the functionality poorly in the driver. Note that the remap_io_sg path does get exercises when using Xorg on my Thinkpad X1, so this should be considered lightly tested, I've not managed to hit the remap_io_mapping path at all. This patch (of 4): Add a version of remap_pfn_range that does not call track_pfn_range. This will be used to fix horrible abuses of VM internals in the i915 driver.

During the migration, TLB will be shot down on all CPUs that the process has run on recently. Because in the hint page fault handler, the PTE will be made accessible before the migration is tried. The overhead of TLB shooting down can be high, so it's better to be avoided if possible. In fact, if we delay mapping the page until migration, that can be avoided. This is what this patch doing. For the multiple threads applications, it's possible that a page is accessed by multiple threads almost at the same time. In the original implementation, because the first thread will install the accessible PTE before migrating the page, the other threads may access the page directly before the page is made inaccessible again during migration. While with the patch, the second thread will go through the page fault handler too. And because of the PageLRU() checking in the following code path, migrate_misplaced_page() numamigrate_isolate_page() isolate_lru_page() the migrate_misplaced_page() will return 0, and the PTE will be made accessible in the second thread. This will introduce a little more overhead. But we think the possibility for a page to be accessed by the multiple threads at the same time is low, and the overhead difference isn't too large. If this becomes a problem in some workloads, we need to consider how to reduce the overhead. To test the patch, we run a test case as follows on a 2-socket Intel server (1 NUMA node per socket) with 128GB DRAM (64GB per socket). 1. Run a memory eater on NUMA node 1 to use 40GB memory before running pmbench. 2. Run pmbench (normal accessing pattern) with 8 processes, and 8 threads per process, so there are 64 threads in total. The working-set size of each process is 8960MB, so the total working-set size is 8 * 8960MB = 70GB. The CPU of all pmbench processes is bound to node 1. The pmbench processes will access some DRAM on node 0. 3. After the pmbench processes run for 10 seconds, kill the memory eater. Now, some pages will be migrated from node 0 to node 1 via NUMA balancing. Test results show that, with the patch, the pmbench throughput (page accesses/s) increases 5.5%. The number of the TLB shootdowns interrupts reduces 98% (from ~4.7e7 to ~9.7e5) with about 9.2e6 pages (35.8GB) migrated. From the perf profile, it can be found that the CPU cycles spent by try_to_unmap() and its callees reduces from 6.02% to 0.47%. That is, the CPU cycles spent by TLB shooting down decreases greatly.

This patch (of 3): Currently MREMAP_DONTUNMAP only accepts private anonymous mappings. This restriction was placed initially for simplicity and not because there exists a technical reason to do so. This change will widen the support to include any mappings which are not VM_DONTEXPAND or VM_PFNMAP. The primary use case is to support MREMAP_DONTUNMAP on mappings which may have been created from a memfd. This change will result in mremap(MREMAP_DONTUNMAP) returning -EINVAL if VM_DONTEXPAND or VM_PFNMAP mappings are specified. Lokesh Gidra who works on the Android JVM, provided an explanation of how such a feature will improve Android JVM garbage collection: "Android is developing a new garbage collector (GC), based on userfaultfd. The garbage collector will use userfaultfd (uffd) on the java heap during compaction. On accessing any uncompacted page, the application threads will find it missing, at which point the thread will create the compacted page and then use UFFDIO_COPY ioctl to get it mapped and then resume execution. Before starting this compaction, in a stop-the-world pause the heap will be mremap(MREMAP_DONTUNMAP) so that the java heap is ready to receive UFFD_EVENT_PAGEFAULT events after resuming execution. To speedup mremap operations, pagetable movement was optimized by moving PUD entries instead of PTE entries [1]. It was necessary as mremap of even modest sized memory ranges also took several milliseconds, and stopping the application for that long isn't acceptable in response-time sensitive cases. With UFFDIO_CONTINUE feature [2], it will be even more efficient to implement this GC, particularly the 'non-moveable' portions of the heap. It will also help in reducing the need to copy (UFFDIO_COPY) the pages. However, for this to work, the java heap has to be on a 'shared' vma. Currently MREMAP_DONTUNMAP only supports private anonymous mappings, this patch will enable using UFFDIO_CONTINUE for the new userfaultfd-based heap compaction."

The kernel virtual mapping layer grew support for mapping memory with > PAGE_SIZE ptes with commit 0ddab1d2ed66 ("lib/ioremap.c: add huge I/O map capability interfaces"), and implemented support for using those huge page mappings with ioremap. According to the submission, the use-case is mapping very large non-volatile memory devices, which could be GB or TB: https://lore.kernel.org/lkml/1425404664-19675-1-git-send-email-toshi.kani@hp.com/ The benefit is said to be in the overhead of maintaining the mapping, perhaps both in memory overhead and setup / teardown time. Memory overhead for the mapping with a 4kB page and 8 byte page table is 2GB per TB of mapping, down to 4MB / TB with 2MB pages. The same huge page vmap infrastructure can be quite easily adapted and used for mapping vmalloc memory pages without more complexity for arch or core vmap code. However unlike ioremap, vmalloc page table overhead is not a real problem, so the advantage to justify this is performance. Several of the most structures in the kernel (e.g., vfs and network hash tables) are allocated with vmalloc on NUMA machines, in order to distribute access bandwidth over the machine. Mapping these with larger pages can improve TLB usage significantly, for example this reduces TLB misses by nearly 30x on a `git diff` workload on a 2-node POWER9 (59,800 -> 2,100) and reduces CPU cycles by 0.54%, due to vfs hashes being allocated with 2MB pages. [ Other numbers? - The difference is even larger in a guest due to more costly TLB misses. - Eric Dumazet was keen on the network hash performance possibilities. - Other archs? Ding was doing x86 testing. ] The kernel module allocator also uses vmalloc to map module images even on non-NUMA, which can result in high iTLB pressure on highly modular distro type of kernels. This series does not implement huge mappings for modules yet, but it's a step along the way. Rick Edgecombe was looking at that IIRC. The per-cpu allocator similarly might be able to take advantage of this. Also on the todo list. The disadvantages of this I can see are: * Memory fragmentation can waste some physical memory because it will attempt to allocate larger pages to fit the required size, rounding up (once the requested size is >= 2MB). - I don't see it being a big problem in practice unless some user crops up that allocates thousands of 2.5MB ranges. We can tewak heuristics a bit there if needed to reduce peak waste. * Less granular mappings can make the NUMA distribution less balanced. - Similar to the above. - Could also allocate all major system hashes with one allocation up-front and spread them all across the one block, which should help overall NUMA distribution and reduce fragmentation waste. * Callers might expect something about the underlying allocated pages. - Tried to keep the apperance of base PAGE_SIZE pages throughout the APIs and exposed data structures. - Added a VM_NO_HUGE_VMAP flag to hammer troublesome cases with. - Finally, added a nohugevmalloc boot option to turn it off (independent of nohugeiomap). This patch (of 14): ARM uses its own PMD folding scheme which is missing pud_page which should just pass through to pmd_page. Move this from the 3-level page table to common header.

Whether or not a vmap is huge depends on the architecture details, alignments, boot options, etc., which the caller can not be expected to know. Therefore HUGE_VMAP is a regression for vmalloc_to_page. This change teaches vmalloc_to_page about larger pages, and returns the struct page that corresponds to the offset within the large page.

This removes code and indirection, and allows constant-folding of dead code for unsupported levels. This also adds a prot argument to the arch query. This is unused currently but could help with some architectures (e.g., some powerpc processors can't map uncacheable memory with large pages).

Config option HAVE_ARCH_HUGE_VMALLOC enables support on architectures that define HAVE_ARCH_HUGE_VMAP and supports PMD sized vmap mappings. vmalloc will attempt to allocate PMD-sized pages if allocating PMD size or larger, and fall back to small pages if that was unsuccessful. Architectures must ensure that any arch specific vmalloc allocations that require PAGE_SIZE mappings (e.g., module allocations vs strict module rwx) use the VM_NOHUGE flag to inhibit larger mappings. This can result in more internal fragmentation and memory overhead for a given allocation, an option nohugevmalloc is added to disable at boot.

Fix this by adding a check for vb->dirty before accessing vmap_area structure since vb->dirty will be set to VMAP_BBMAP_BITS in purge path checking for this will prevent the use after free.

Roughly 900 warnings of about 21.000 kernel-doc warnings in the kernel tree warn with 'cannot understand function prototype:', i.e., the kernel-doc parser cannot parse the function's signature. The majority, about 600 cases of those, are just struct definitions following the kernel-doc description. Further, spot-check investigations suggest that the authors of the specific kernel-doc descriptions simply were not aware that the general format for a kernel-doc description for a structure requires to prefix the struct name with the keyword 'struct', as in 'struct struct_name - Brief description.'. Details on kernel-doc are at the Link below. Without the struct keyword, kernel-doc does not check if the kernel-doc description fits to the actual struct definition in the source code. Fortunately, in roughly a quarter of these cases, the kernel-doc description is actually complete wrt. its corresponding struct definition. So, the trivial change adding the struct keyword will allow us to keep the kernel-doc descriptions more consistent for future changes, by checking for new kernel-doc warnings. Also, some of the files in ./include/ are not assigned to a specific MAINTAINERS section and hence have no dedicated maintainer. So, if needed, the files in ./include/ are also assigned to the fitting MAINTAINERS section, as I need to identify whom to send the clean-up patch anyway. Here is the change from this kernel-doc janitorial work in the ./include/ directory for MEMORY MANAGEMENT. This patch (of 2): Commit a520110e4a15 ("mm: split out a new pagewalk.h header from mm.h") adds a new file in ./include/linux, but misses to update MAINTAINERS accordingly. Hence, ./scripts/get_maintainers.pl include/linux/pagewalk.h points only to lkml as general fallback for all files, whereas the original include/linux/mm.h clearly marks this file part of MEMORY MANAGEMENT. Assign include/linux/pagewalk.h to MEMORY MANAGEMENT.

For example ksize() and krealloc() may end up calling it on KFENCE allocated memory. In this case the memory will be tagged with KASAN_SHADOW_INIT, which a subsequent patch ("kasan: initialize shadow to TAG_INVALID for SW_TAGS") will set to the same value as KASAN_TAG_INVALID, causing kasan_byte_accessible() to fail when called on non-slab memory. This highlighted the fact that the check in kasan_byte_accessible() was inconsistent with checks as implemented for loads and stores (kasan_check_range() in SW tags mode and hardware-implemented checks in HW tags mode). kasan_check_range() does not have a check for KASAN_TAG_INVALID, and instead has a comparison against KASAN_SHADOW_START. In HW tags mode, we do not have either, but we do set TCR_EL1.TCMA which corresponds with the comparison against KASAN_TAG_KERNEL. Therefore, update kasan_byte_accessible() for both SW and HW tags modes to correspond with the respective checks on loads and stores.

The underlying idea is that since that memory hasn't been allocated yet, it's only supposed to be dereferenced through a pointer with the native 0xFF tag. While this is a good idea in terms on consistency, practically it doesn't bring any benefit. Since the 0xFF pointer tag is a match-all tag, it doesn't matter what tag the accessed memory has. No accesses through 0xFF-tagged pointers are considered buggy by KASAN. This patch changes the default tag value for unallocated memory to 0xFE, which is the tag KASAN uses for inaccessible memory. This doesn't affect accesses through 0xFF-tagged pointer to this memory, but this allows KASAN to detect wild and large out-of-bounds invalid memory accesses through otherwise-tagged pointers. This is a prepatory patch for the next one, which changes the tag-based KASAN modes to not poison the boot memory.

This results in kasan_free_pages() being called, which poisons that memory. Poisoning all that memory lengthens boot time. The most noticeable effect is observed with the HW_TAGS mode. A boot-time impact may potentially also affect systems with large amount of RAM. This patch changes the tag-based modes to not poison the memory during the memblock->page_alloc transition. An exception is made for KASAN_GENERIC. Since it marks all new memory as accessible, not poisoning the memory released from memblock will lead to KASAN missing invalid boot-time accesses to that memory. With KASAN_SW_TAGS, as it uses the invalid 0xFE tag as the default tag for all memory, it won't miss bad boot-time accesses even if the poisoning of memblock memory is removed. With KASAN_HW_TAGS, the default memory tags values are unspecified. Therefore, if memblock poisoning is removed, this KASAN mode will miss the mentioned type of boot-time bugs with a 1/16 probability. This is taken as an acceptable trafe-off. Internally, the poisoning is removed as follows. __free_pages_core() is used when exposing fresh memory during system boot and when onlining memory during hotplug. This patch adds a new FPI_SKIP_KASAN_POISON flag and passes it to __free_pages_ok() through free_pages_prepare() from __free_pages_core(). If FPI_SKIP_KASAN_POISON is set, kasan_free_pages() is not called. All memory allocated normally when the boot is over keeps getting poisoned as usual.

This patch (of 5): This change adds an argument to mte_set_mem_tag_range() that allows to enable memory initialization when settinh the allocation tags. The implementation uses stzg instruction instead of stg when this argument indicates to initialize memory. Combining setting allocation tags with memory initialization will improve HW_TAGS KASAN performance when init_on_alloc/free is enabled. This change doesn't integrate memory initialization with KASAN, this is done is subsequent patches in this series.

With this change, kernel_init_free_pages() is no longer called when both HW_TAGS KASAN and init_on_alloc/free are enabled. Instead, memory is initialized in KASAN runtime. To avoid discrepancies with which memory gets initialized that can be caused by future changes, both KASAN and kernel_init_free_pages() hooks are put together and a warning comment is added. This patch changes the order in which memory initialization and page poisoning hooks are called. This doesn't lead to any side-effects, as whenever page poisoning is enabled, memory initialization gets disabled. Combining setting allocation tags with memory initialization improves HW_TAGS KASAN performance when init_on_alloc/free is enabled.

With this change, memory initialization memset() is no longer called when both HW_TAGS KASAN and init_on_alloc are enabled. Instead, memory is initialized in KASAN runtime. The memory initialization memset() is moved into slab_post_alloc_hook() that currently directly follows the initialization loop. A new argument is added to slab_post_alloc_hook() that indicates whether to initialize the memory or not. To avoid discrepancies with which memory gets initialized that can be caused by future changes, both KASAN hook and initialization memset() are put together and a warning comment is added. Combining setting allocation tags with memory initialization improves HW_TAGS KASAN performance when init_on_alloc is enabled.

This is certainly not worth a pr_info.*(). b) not really helpful for debugging: we don't have any details *why* these PFNs are busy, and that is what we usually care about. c) not complete: there are other cases where we fail alloc_contig_range() using different paths that are not getting recorded. For example, we reach this path once we succeeded in isolating pageblocks, but failed to migrate some pages - which can happen easily on ZONE_NORMAL (i.e., has_unmovable_pages() is racy) but also on ZONE_MOVABLE i.e., we would have to retry longer to migrate). For example via virtio-mem when unplugging memory, we can create quite some noise (especially with ZONE_NORMAL) that is not of interest to users - it's expected that some allocations may fail as memory is busy. Let's just drop that pr_info_ratelimit() and rather implement a dynamic debugging mechanism in the future that can give us a better reason why alloc_contig_range() failed on specific pages.

I was poking around the __alloc_pages variants trying to understand why they each exist, and couldn't really find a good justification for keeping __alloc_pages and __alloc_pages_nodemask as separate functions. That led to getting rid of alloc_pages_current() and then I noticed the documentation was bad, and then I noticed the mempolicy documentation wasn't included. Anyway, this is all cleanups & doc fixes. This patch (of 7): We have two masks involved -- the nodemask and the gfp mask, so alloc_mask is an unclear name.

The most common source of these failures seems to be page migration which doesn't provide any useful information on the reason of the failure by itself. alloc_contig_range can report those failures as it holds a list of migrate-failed pages. The information logged by dump_page() has already proven helpful for debugging allocation issues, like identifying long-term pinnings on ZONE_MOVABLE or MIGRATE_CMA. Let's use the dynamic debugging infrastructure, such that we avoid flooding the logs and creating a lot of noise on frequent alloc_contig_range() calls. This information is helpful for debugging only. There are two ifdefery conditions to support common dyndbg options: - CONFIG_DYNAMIC_DEBUG_CORE && DYNAMIC_DEBUG_MODULE It aims for supporting the feature with only specific file with adding ccflags. - CONFIG_DYNAMIC_DEBUG It aims for supporting the feature with system wide globally. A simple example to enable the feature: Admin could enable the dump like this(by default, disabled) echo "func alloc_contig_dump_pages +p" > control Admin could disable it. echo "func alloc_contig_dump_pages =_" > control Detail goes Documentation/admin-guide/dynamic-debug-howto.rst A concern is utility functions in dump_page use inconsistent loglevels. In the future, we might want to make the loglevels used inside dump_page() consistent and eventually rework the way we log the information here. See [1].

If no other semantic changes are needed, it can be made more efficient. Despite that, this is a performance-related for users that require multiple pages for an operation without multiple round-trips to the page allocator.

Other potential other users are batch allocations for page cache readahead, fault around and SLUB allocations when high-order pages are unavailable. It's unknown how much benefit would be seen by converting multiple page allocation calls to a single batch or what difference it may make to headline performance. Light testing of my own running dbench over NFS passed. Chuck and Jesper conducted their own tests and details are included in the changelogs. Patch 1 renames a variable name that is particularly unpopular Patch 2 adds a bulk page allocator Patch 3 adds an array-based version of the bulk allocator Patches 4-5 adds micro-optimisations to the implementation Patches 6-7 SUNRPC user Patches 8-9 Network page_pool user This patch (of 9): Review feedback of the bulk allocator twice found problems with "alloced" being a counter for pages allocated. The naming was based on the API name "alloc" and was based on the idea that verbal communication about malloc tends to use the fake word "malloced" instead of the fake word mallocated. To be consistent, this preparation patch renames alloced to allocated in rmqueue_bulk so the bulk allocator and per-cpu allocator use similar names when the bulk allocator is introduced.

A caller requests a number of pages to be allocated and added to a list. The API is not guaranteed to return the requested number of pages and may fail if the preferred allocation zone has limited free memory, the cpuset changes during the allocation or page debugging decides to fail an allocation. It's up to the caller to request more pages in batch if necessary. Note that this implementation is not very efficient and could be improved but it would require refactoring. The intent is to make it available early to determine what semantics are required by different callers. Once the full semantics are nailed down, it can be refactored.

The micro-benchmark results are promising. I ran a mixture of 256KB reads and writes over NFSv3. The server's kernel is built with KASAN enabled, so the comparison is exaggerated but I believe it is still valid. I instrumented svc_recv() to measure the latency of each call to svc_alloc_arg() and report it via a trace point. The following results are averages across the trace events. Single page: 25.007 us per call over 532,571 calls Bulk list: 6.258 us per call over 517,034 calls Bulk array: 4.590 us per call over 517,442 calls This patch (of 2) Refactor: I'm about to use the loop variable @i for something else. As far as the "i++" is concerned, that is a post-increment. The value of @i is not used subsequently, so the increment operator is unnecessary and can be removed. Also note that nfsd_read_actor() was renamed nfsd_splice_actor() by commit cf8208d0eabd ("sendfile: convert nfsd to splice_direct_to_actor()").
