Qais Yousef	d2c741290f	sched/uclamp: Fix iowait boost escaping uclamp restriction ... [ Upstream commit d37aee9018e68b0d356195caefbb651910e0bbfa ] iowait_boost signal is applied independently of util and doesn't take into account uclamp settings of the rq. An io heavy task that is capped by uclamp_max could still request higher frequency because sugov_iowait_apply() doesn't clamp the boost via uclamp_rq_util_with() like effective_cpu_util() does. Make sure that iowait_boost honours uclamp requests by calling uclamp_rq_util_with() when applying the boost.

Lukasz Luba	8f1b971b47	sched/cpufreq: Consider reduced CPU capacity in energy calculation ... Energy Aware Scheduling (EAS) needs to predict the decisions made by SchedUtil. The map_util_freq() exists to do that. There are corner cases where the max allowed frequency might be reduced (due to thermal). SchedUtil as a CPUFreq governor, is aware of that but EAS is not. This patch aims to address it. SchedUtil stores the maximum allowed frequency in 'sugov_policy::next_freq' field. EAS has to predict that value, which is the real used frequency. That value is made after a call to cpufreq_driver_resolve_freq() which clamps to the CPUFreq policy limits. In the existing code EAS is not able to predict that real frequency. This leads to energy estimation errors. To avoid wrong energy estimation in EAS (due to frequency miss prediction) make sure that the step which calculates Performance Domain frequency, is also aware of the allowed CPU capacity. Furthermore, modify map_util_freq() to not extend the frequency value. Instead, use map_util_perf() to extend the util value in both places: SchedUtil and EAS, but for EAS clamp it to max allowed CPU capacity. In the end, we achieve the same desirable behavior for both subsystems and alignment in regards to the real CPU frequency.

Note that sugov_update_next_freq() may return false, that means the caller sugov_fast_switch() will do nothing except fast switch check. Similarly, sugov_deferred_update() also has unnecessary operations of raw_spin_{lock,unlock} in sugov_update_single_freq() for that case. So, let's call sugov_update_next_freq() before the fast switch check to avoid unnecessary behaviors above.

First off, some cpufreq drivers (eg. intel_pstate) can pass hints beyond the current target frequency to the hardware and there are no provisions for doing that in the cpufreq framework. In particular, today the driver has to assume that it should not allow the frequency to fall below the one requested by the governor (or the required capacity may not be provided) which may not be the case and which may lead to excessive energy usage in some scenarios. Second, the hints passed by these drivers to the hardware need not be in terms of the frequency, so representing the utilization numbers coming from the scheduler as frequency before passing them to those drivers is not really useful. Address the two points above by adding a special-purpose replacement for the ->fast_switch callback, called ->adjust_perf, allowing the governor to pass abstract performance level (rather than frequency) values for the minimum (required) and target (desired) performance along with the CPU capacity to compare them to. Also update the schedutil governor to use the new callback instead of ->fast_switch if present and if the utilization mertics are frequency-invariant (that is requisite for the direct mapping between the utilization and the CPU performance levels to be a reasonable approximation).

Viresh Kumar	23a881852f	cpufreq: schedutil: Don't skip freq update if need_freq_update is set ... The cpufreq policy's frequency limits (min/max) can get changed at any point of time, while schedutil is trying to update the next frequency. Though the schedutil governor has necessary locking and support in place to make sure we don't miss any of those updates, there is a corner case where the governor will find that the CPU is already running at the desired frequency and so may skip an update. For example, consider that the CPU can run at 1 GHz, 1.2 GHz and 1.4 GHz and is running at 1 GHz currently. Schedutil tries to update the frequency to 1.2 GHz, during this time the policy limits get changed as policy->min = 1.4 GHz. As schedutil (and cpufreq core) does clamp the frequency at various instances, we will eventually set the frequency to 1.4 GHz, while we will save 1.2 GHz in sg_policy->next_freq. Now lets say the policy limits get changed back at this time with policy->min as 1 GHz. The next time schedutil is invoked by the scheduler, we will reevaluate the next frequency (because need_freq_update will get set due to limits change event) and lets say we want to set the frequency to 1.2 GHz again. At this point sugov_update_next_freq() will find the next_freq == current_freq and will abort the update, while the CPU actually runs at 1.4 GHz. Until now need_freq_update was used as a flag to indicate that the policy's frequency limits have changed, and that we should consider the new limits while reevaluating the next frequency. This patch fixes the above mentioned issue by extending the purpose of the need_freq_update flag. If this flag is set now, the schedutil governor will not try to abort a frequency change even if next_freq == current_freq. As similar behavior is required in the case of CPUFREQ_NEED_UPDATE_LIMITS flag as well, need_freq_update will never be set to false if that flag is set for the driver. We also don't need to consider the need_freq_update flag in sugov_update_single() anymore to handle the special case of busy CPU, as we won't abort a frequency update anymore.

Rafael J. Wysocki	d1e7c2996e	cpufreq: schedutil: Always call driver if CPUFREQ_NEED_UPDATE_LIMITS is set ... Because sugov_update_next_freq() may skip a frequency update even if the need_freq_update flag has been set for the policy at hand, policy limits updates may not take effect as expected. For example, if the intel_pstate driver operates in the passive mode with HWP enabled, it needs to update the HWP min and max limits when the policy min and max limits change, respectively, but that may not happen if the target frequency does not change along with the limit at hand. In particular, if the policy min is changed first, causing the target frequency to be adjusted to it, and the policy max limit is changed later to the same value, the HWP max limit will not be updated to follow it as expected, because the target frequency is still equal to the policy min limit and it will not change until that limit is updated. To address this issue, modify get_next_freq() to let the driver callback run if the CPUFREQ_NEED_UPDATE_LIMITS cpufreq driver flag is set regardless of whether or not the new frequency to set is equal to the previous one.

Qais Yousef	46609ce227	sched/uclamp: Protect uclamp fast path code with static key ... There is a report that when uclamp is enabled, a netperf UDP test regresses compared to a kernel compiled without uclamp. https://lore.kernel.org/lkml/20200529100806.GA3070@suse.de/ While investigating the root cause, there were no sign that the uclamp code is doing anything particularly expensive but could suffer from bad cache behavior under certain circumstances that are yet to be understood. https://lore.kernel.org/lkml/20200616110824.dgkkbyapn3io6wik@e107158-lin/ To reduce the pressure on the fast path anyway, add a static key that is by default will skip executing uclamp logic in the enqueue/dequeue_task() fast path until it's needed. As soon as the user start using util clamp by: 1. Changing uclamp value of a task with sched_setattr() 2. Modifying the default sysctl_sched_util_clamp_{min, max} 3. Modifying the default cpu.uclamp.{min, max} value in cgroup We flip the static key now that the user has opted to use util clamp. Effectively re-introducing uclamp logic in the enqueue/dequeue_task() fast path. It stays on from that point forward until the next reboot. This should help minimize the effect of util clamp on workloads that don't need it but still allow distros to ship their kernels with uclamp compiled in by default. SCHED_WARN_ON() in uclamp_rq_dec_id() was removed since now we can end up with unbalanced call to uclamp_rq_dec_id() if we flip the key while a task is running in the rq. Since we know it is harmless we just quietly return if we attempt a uclamp_rq_dec_id() when rq->uclamp[].bucket[].tasks is 0. In schedutil, we introduce a new uclamp_is_enabled() helper which takes the static key into account to ensure RT boosting behavior is retained. The following results demonstrates how this helps on 2 Sockets Xeon E5 2x10-Cores system. nouclamp uclamp uclamp-static-key Hmean send-64 162.43 ( 0.00%) 157.84 * -2.82%* 163.39 * 0.59%* Hmean send-128 324.71 ( 0.00%) 314.78 * -3.06%* 326.18 * 0.45%* Hmean send-256 641.55 ( 0.00%) 628.67 * -2.01%* 648.12 * 1.02%* Hmean send-1024 2525.28 ( 0.00%) 2448.26 * -3.05%* 2543.73 * 0.73%* Hmean send-2048 4836.14 ( 0.00%) 4712.08 * -2.57%* 4867.69 * 0.65%* Hmean send-3312 7540.83 ( 0.00%) 7425.45 * -1.53%* 7621.06 * 1.06%* Hmean send-4096 9124.53 ( 0.00%) 8948.82 * -1.93%* 9276.25 * 1.66%* Hmean send-8192 15589.67 ( 0.00%) 15486.35 * -0.66%* 15819.98 * 1.48%* Hmean send-16384 26386.47 ( 0.00%) 25752.25 * -2.40%* 26773.74 * 1.47%* The perf diff between nouclamp and uclamp-static-key when uclamp is disabled in the fast path: 8.73% -1.55% [kernel.kallsyms] [k] try_to_wake_up 0.07% +0.04% [kernel.kallsyms] [k] deactivate_task 0.13% -0.02% [kernel.kallsyms] [k] activate_task The diff between nouclamp and uclamp-static-key when uclamp is enabled in the fast path: 8.73% -0.72% [kernel.kallsyms] [k] try_to_wake_up 0.13% +0.39% [kernel.kallsyms] [k] activate_task 0.07% +0.38% [kernel.kallsyms] [k] deactivate_task Fixes: 69842cba9a ("sched/uclamp: Add CPU's clamp buckets refcounting") Reported-by: Mel Gorman <mgorman@suse.de> Signed-off-by: Qais Yousef <qais.yousef@arm.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Tested-by: Lukasz Luba <lukasz.luba@arm.com> Link: https://lkml.kernel.org/r/20200630112123.12076-3-qais.yousef@arm.com	2020-07-08 11:39:01 +02:00
Quentin Perret	10dd8573b0	cpufreq: Register governors at core_initcall ... Currently, most CPUFreq governors are registered at the core_initcall time when the given governor is the default one, and the module_init time otherwise. In preparation for letting users specify the default governor on the kernel command line, change all of them to be registered at the core_initcall unconditionally, as it is already the case for the schedutil and performance governors. This will allow us to assume that builtin governors have been registered before the built-in CPUFreq drivers probe. And since all governors have similar init/exit patterns now, introduce two new macros, cpufreq_governor_{init,exit}(), to factorize the code.

Quentin Perret	bdfa61448f	ANDROID: sched: Allow EAS without schedutil ... This effectively reverts 531b5c9f5c ("sched/topology: Make Energy Aware Scheduling depend on schedutil"), and updates the documentation accordingly. In the context of GKI 2.0, some partners need to use a custom cpufreq govenor, but would like to keep EAS enabled. Remove the hard dependency between them.

Valentin Schneider	d2b58a286e	sched/uclamp: Rename uclamp_util_with() into uclamp_rq_util_with() ... The current helper returns (CPU) rq utilization with uclamp restrictions taken into account. A uclamp task utilization helper would be quite helpful, but this requires some renaming. Prepare the code for the introduction of a uclamp_task_util() by renaming the existing uclamp_util_with() to uclamp_rq_util_with().

Rafael J. Wysocki	85572c2c4a	cpufreq: Avoid leaving stale IRQ work items during CPU offline ... The scheduler code calling cpufreq_update_util() may run during CPU offline on the target CPU after the IRQ work lists have been flushed for it, so the target CPU should be prevented from running code that may queue up an IRQ work item on it at that point. Unfortunately, that may not be the case if dvfs_possible_from_any_cpu is set for at least one cpufreq policy in the system, because that allows the CPU going offline to run the utilization update callback of the cpufreq governor on behalf of another (online) CPU in some cases. If that happens, the cpufreq governor callback may queue up an IRQ work on the CPU running it, which is going offline, and the IRQ work may not be flushed after that point. Moreover, that IRQ work cannot be flushed until the "offlining" CPU goes back online, so if any other CPU calls irq_work_sync() to wait for the completion of that IRQ work, it will have to wait until the "offlining" CPU is back online and that may not happen forever. In particular, a system-wide deadlock may occur during CPU online as a result of that. The failing scenario is as follows. CPU0 is the boot CPU, so it creates a cpufreq policy and becomes the "leader" of it (policy->cpu). It cannot go offline, because it is the boot CPU. Next, other CPUs join the cpufreq policy as they go online and they leave it when they go offline. The last CPU to go offline, say CPU3, may queue up an IRQ work while running the governor callback on behalf of CPU0 after leaving the cpufreq policy because of the dvfs_possible_from_any_cpu effect described above. Then, CPU0 is the only online CPU in the system and the stale IRQ work is still queued on CPU3. When, say, CPU1 goes back online, it will run irq_work_sync() to wait for that IRQ work to complete and so it will wait for CPU3 to go back online (which may never happen even in principle), but (worse yet) CPU0 is waiting for CPU1 at that point too and a system-wide deadlock occurs. To address this problem notice that CPUs which cannot run cpufreq utilization update code for themselves (for example, because they have left the cpufreq policies that they belonged to), should also be prevented from running that code on behalf of the other CPUs that belong to a cpufreq policy with dvfs_possible_from_any_cpu set and so in that case the cpufreq_update_util_data pointer of the CPU running the code must not be NULL as well as for the CPU which is the target of the cpufreq utilization update in progress. Accordingly, change cpufreq_this_cpu_can_update() into a regular function in kernel/sched/cpufreq.c (instead of a static inline in a header file) and make it check the cpufreq_update_util_data pointer of the local CPU if dvfs_possible_from_any_cpu is set for the target cpufreq policy. Also update the schedutil governor to do the cpufreq_this_cpu_can_update() check in the non-fast-switch case too to avoid the stale IRQ work issues.
