James Clark	ba81399402	coresight: Fix TRCCONFIGR.QE sysfs interface ... commit ea75a342aed5ed72c87f38fbe0df2f5df7eae374 upstream. It's impossible to program a valid value for TRCCONFIGR.QE when TRCIDR0.QSUPP==0b10. In that case the following is true: Q element support is implemented, and only supports Q elements without instruction counts. TRCCONFIGR.QE can only take the values 0b00 or 0b11. Currently the low bit of QSUPP is checked to see if the low bit of QE can be written to, but as you can see when QSUPP==0b10 the low bit is cleared making it impossible to ever write the only valid value of 0b11 to QE. 0b10 would be written instead, which is a reserved QE value even for all values of QSUPP. The fix is to allow writing the low bit of QE for any non zero value of QSUPP. This change also ensures that the low bit is always set, even when the user attempts to only set the high bit.

This will be additional to other restrictions (e.g, the TRBE alignment for working around TRBE_WORKAROUND_OVERWRITE_IN_FILL_MODE, where there is a minimum of PAGE_SIZE.

Suzuki K Poulose	f0908accc4	UPSTREAM: coresight: trbe: Workaround TRBE errata overwrite in FILL mode ... ARM Neoverse-N2 (#2139208) and Cortex-A710(##2119858) suffers from an erratum, which when triggered, might cause the TRBE to overwrite the trace data already collected in FILL mode, in the event of a WRAP. i.e, the TRBE doesn't stop writing the data, instead wraps to the base and could write upto 3 cache line size worth trace. Thus, this could corrupt the trace at the "BASE" pointer. The workaround is to program the write pointer 256bytes from the base, such that if the erratum is triggered, it doesn't overwrite the trace data that was captured. This skipped region could be padded with ignore packets at the end of the session, so that the decoder sees a continuous buffer with some padding at the beginning. The trace data written at the base is considered lost as the limit could have been in the middle of the perf ring buffer, and jumping to the "base" is not acceptable. We set the flags already to indicate that some amount of trace was lost during the FILL event IRQ. So this is fine. One important change with the work around is, we program the TRBBASER_EL1 to current page where we are allowed to write. Otherwise, it could overwrite a region that may be consumed by the perf. Towards this, we always make sure that the "handle->head" and thus the trbe_write is PAGE_SIZE aligned, so that we can set the BASE to the PAGE base and move the TRBPTR to the 256bytes offset.

Suzuki K Poulose	84271cf9f0	UPSTREAM: coresight: trbe: Add infrastructure for Errata handling ... Add a minimal infrastructure to keep track of the errata affecting the given TRBE instance. Given that we have heterogeneous CPUs, we have to manage the list per-TRBE instance to be able to apply the work around as needed. Thus we will need to check if individual CPUs are affected by the erratum. We rely on the arm64 errata framework for the actual description and the discovery of a given erratum, to keep the Erratum work around at a central place and benefit from the code and the advertisement from the kernel. Though we could reuse the "this_cpu_has_cap()" to apply an erratum work around, it is a bit of a heavy operation, as it must go through the "erratum" detection check on the CPU every time it is called (e.g, scanning through a table of affected MIDRs). Since we need to do this check for every session, may be multiple times (depending on the wrok around), we could save the cycles by caching the affected errata per-CPU instance in the per-CPU struct trbe_cpudata. Since we are only interested in the errata affecting the TRBE driver, we only need to track a very few of them per-CPU. Thus we use a local mapping of the CPUCAP for the erratum to avoid bloating up a bitmap for trbe_cpudata. i.e, each arm64 TRBE erratum bit is assigned a "index" within the driver to track. Each trbe instance updates the list of affected erratum at probe time on the CPU. This makes sure that we can easily access the list of errata on a given TRBE instance without much overhead.

Suzuki K Poulose	0b46078ddc	UPSTREAM: coresight: trbe: Prohibit trace before disabling TRBE ... When the TRBE generates an IRQ, we stop the TRBE, collect the trace and then reprogram the TRBE with the updated buffer pointers, whenever possible. We might also leave the TRBE disabled, if there is not enough space left in the buffer. However, we do not touch the ETE at all during all of this. This means the ETE is only disabled when the event is disabled later (via irq_work). This is incorrect, as the ETE trace is still ON without actually being captured and may be routed to the ATB (even if it is for a short duration). So, we move the CPU into trace prohibited state always before disabling the TRBE, upon entering the IRQ handler. The state is restored if the TRBE is enabled back. Otherwise the trace remains prohibited. Since, the ETM/ETE driver now controls the TRFCR_EL1 per session, the tracing can be restored/enabled back when the event is rescheduled in.

Suzuki K Poulose	eafd22e7f7	UPSTREAM: coresight: etm4x: Use Trace Filtering controls dynamically ... The Trace Filtering support (FEAT_TRF) ensures that the ETM can be prohibited from generating any trace for a given EL. This is much stricter knob, than the TRCVICTLR exception level masks, which doesn't prevent the ETM from generating Context packets for an "excluded" EL. At the moment, we do a onetime enable trace at user and kernel and leave it untouched for the kernel life time. This implies that the ETM could potentially generate trace packets containing the kernel addresses, and thus leaking the kernel virtual address in the trace. This patch makes the switch dynamic, by honoring the filters set by the user and enforcing them in the TRFCR controls. We also rename the cpu_enable_tracing() appropriately to cpu_detect_trace_filtering() and the drvdata member trfc => trfcr to indicate the "value" of the TRFCR_EL1.

James Clark	5f4d516d89	UPSTREAM: coresight: Don't immediately close events that are run on invalid CPU/sink combos ... When a traced process runs on a CPU that can't reach the selected sink, the event will be stopped with PERF_HES_STOPPED. This means that even if the process migrates to a valid CPU, tracing will not resume. This can be reproduced (on N1SDP) by using taskset to start the process on CPU 0, and then switching it to CPU 2 (ETF 1 is only reachable from CPU 2): taskset --cpu-list 0 ./perf record -e cs_etm/@tmc_etf1/ --per-thread -- taskset --cpu-list 2 ls This produces a single 0 length AUX record, and then no more trace: 0x3c8 [0x30]: PERF_RECORD_AUX offset: 0 size: 0 flags: 0x1 [T] After the fix, the same command produces normal AUX records. The perf self test "89: Check Arm CoreSight trace data recording and synthesized samples" no longer fails intermittently. This was because the taskset in the test is after the fork, so there is a period where the task is scheduled on a random CPU rather than forced to a valid one. Specifically selecting an invalid CPU will still result in a failure to open the event because it will never produce trace: ./perf record -C 2 -e cs_etm/@tmc_etf0/ failed to mmap with 12 (Cannot allocate memory) The only scenario that has changed is if the CPU mask has a valid CPU sink combo in it. Testing ======= * Coresight self test passes consistently: ./perf test Coresight * CPU wide mode still produces trace: ./perf record -e cs_etm// -a * Invalid -C options still fail to open: ./perf record -C 2,3 -e cs_etm/@tmc_etf0/ failed to mmap with 12 (Cannot allocate memory) * Migrating a task to a valid sink/CPU now produces trace: taskset --cpu-list 0 ./perf record -e cs_etm/@tmc_etf1/ --per-thread -- taskset --cpu-list 2 ls * If the task remains on an invalid CPU, no trace is emitted: taskset --cpu-list 0 ./perf record -e cs_etm/@tmc_etf1/ --per-thread -- ls Bug: 213931796 Reviewed-by: Suzuki K Poulose <suzuki.poulose@arm.com> Signed-off-by: James Clark <james.clark@arm.com> Link: https://lore.kernel.org/r/20210922125144.133872-2-james.clark@arm.com Signed-off-by: Suzuki K Poulose <suzuki.poulose@arm.com> Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> (cherry picked from commit 8c60acbcb982bfff14d1e85094474671c4f3d006) Signed-off-by: Qais Yousef <qais.yousef@arm.com> Change-Id: If0d5639287630bb4ceb6defcebed15d139a1a8b2	2022-01-24 12:14:57 -08:00
Leo Yan	c63411d4b7	UPSTREAM: coresight: tmc-etr: Speed up for bounce buffer in flat mode ... The AUX bounce buffer is allocated with API dma_alloc_coherent(), in the low level's architecture code, e.g. for Arm64, it maps the memory with the attribution "Normal non-cacheable"; this can be concluded from the definition for pgprot_dmacoherent() in arch/arm64/include/asm/pgtable.h. Later when access the AUX bounce buffer, since the memory mapping is non-cacheable, it's low efficiency due to every load instruction must reach out DRAM. This patch changes to allocate pages with dma_alloc_noncoherent(), the driver can access the memory via cacheable mapping; therefore, load instructions can fetch data from cache lines rather than always read data from DRAM, the driver can boost memory performance. After using the cacheable mapping, the driver uses dma_sync_single_for_cpu() to invalidate cacheline prior to read bounce buffer so can avoid read stale trace data.

Uwe Kleine-König	fc7a6209d5	bus: Make remove callback return void ... The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.
