[RFC 0/9] cpufreq: schedutil: Allow remote wakeups

by Viresh Kumar

Hi, This is based of the work done by Steve Muckle [1] before he left Linaro and most of the patches are still under his authorship. I have done couple of improvements (detailed in individual patches) and removed the late callback support [2] as I wasn't sure of the value it adds. We can include it separately if others feel it is required. This series is based on pm/linux-next with patches [3] and [4] applied on top of it. With Android UI and benchmarks the latency of cpufreq response to certain scheduling events can become very critical. Currently, callbacks into schedutil are only made from the scheduler if the target CPU of the event is the same as the current CPU. This means there are certain situations where a target CPU may not run schedutil for some time. One testcase to show this behavior is where a task starts running on CPU0, then a new task is also spawned on CPU0 by a task on CPU1. If the system is configured such that new tasks should receive maximum demand initially, this should result in CPU0 increasing frequency immediately. Because of the above mentioned limitation though this does not occur. This is verified using ftrace with the sample [5] application. This patchset updates the scheduler to call cpufreq callbacks for remote CPUs as well and updates schedutil governor to deal with it. An additional flag is added to cpufreq policies to avoid sending IPIs to remote CPUs to update the frequency, if CPUs on the platform can change frequency of any other CPU. This series is tested with couple of usecases (Android: hackbench, recentfling, galleryfling, vellamo, Ubuntu: hackbench) on ARM hikey board (64 bit octa-core, single policy). Only galleryfling showed minor improvements, while others didn't had much deviation. The reason being that this patchset only targets a corner case, where following are required to be true to improve performance and that doesn't happen too often with these tests: - Task is migrated to another CPU. - The task has maximum demand initially, and should take the CPU to higher OPPs. - And the target CPU doesn't call into schedutil until the next tick, without this patchset. -- viresh [1] https://git.linaro.org/people/steve.muckle/kernel.git/log/?h=pmwg-integrati… [2] https://git.linaro.org/people/steve.muckle/kernel.git/commit/?h=pmwg-integr… [3] https://marc.info/?l=linux-kernel&m=148766093718487&w=2 [4] https://marc.info/?l=linux-kernel&m=148903231720432&w=2 [5] http://pastebin.com/7LkMSRxE Steve Muckle (8): sched: cpufreq: add cpu to update_util_data irq_work: add irq_work_queue_on for !CONFIG_SMP sched: cpufreq: extend irq work to support fast switches sched: cpufreq: remove smp_processor_id() in remote paths sched: cpufreq: detect, process remote callbacks cpufreq: governor: support scheduler cpufreq callbacks on remote CPUs intel_pstate: ignore scheduler cpufreq callbacks on remote CPUs sched: cpufreq: enable remote sched cpufreq callbacks Viresh Kumar (1): cpufreq: Add dvfs_possible_from_any_cpu policy flag drivers/cpufreq/cpufreq-dt.c | 1 + drivers/cpufreq/cpufreq_governor.c | 2 +- drivers/cpufreq/intel_pstate.c | 3 ++ include/linux/cpufreq.h | 9 +++++ include/linux/irq_work.h | 7 ++++ include/linux/sched/cpufreq.h | 1 + kernel/sched/cpufreq.c | 1 + kernel/sched/cpufreq_schedutil.c | 80 +++++++++++++++++++++++++++++--------- kernel/sched/fair.c | 6 ++- kernel/sched/sched.h | 3 +- 10 files changed, 90 insertions(+), 23 deletions(-) -- 2.7.1.410.g6faf27b

[PATCH 00/17] thermal: cpu_cooling: improve interaction with cpufreq core

by Viresh Kumar

Hi Guys, The cpu_cooling driver is designed to use CPU frequency scaling to avoid high thermal states for a platform. But it wasn't glued really well with cpufreq core. This series tries to improve interactions between cpufreq core and cpu_cooling driver and does some fixes/cleanups to the cpu_cooling driver. I am a bit confused about which tree this series should go through, PM or thermal. This series has dependency on few other patches which are already merged in the PM [1] tree and thermal [2] tree. As this is 4.12 material, all of this should go through only one tree to avoid conflicts. I assume that one of Rafael and Rui have to drop the existing patch(es) from their trees and let the other one apply all of these. I would let you guys decide on that. Sorry for the trouble. I have tested it on ARM 32 (exynos) and 64 bit (hikey) boards and have pushed them for 0-day build bot and kernel CI testing as well. We should know if something is broken with these. @Javi: It would be good if you can give them a test, specially because of your work on the "power" specific bits in the driver. Pushed here as well: git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git thermal/cooling -- viresh [1] https://marc.info/?l=linux-kernel&m=148946890403271&w=2 [2] https://marc.info/?l=linux-kernel&m=148644060126593&w=2 Viresh Kumar (17): thermal: cpu_cooling: Avoid accessing potentially freed structures thermal: cpu_cooling: rearrange globals thermal: cpu_cooling: Replace cpufreq_device with cpufreq_dev thermal: cpu_cooling: replace cool_dev with cdev thermal: cpu_cooling: remove cpufreq_cooling_get_level() thermal: cpu_cooling: get rid of a variable in cpufreq_set_cur_state() thermal: cpu_cooling: use cpufreq_policy to register cooling device cpufreq: create cpufreq_table_count_valid_entries() thermal: cpu_cooling: store cpufreq policy thermal: cpu_cooling: OPPs are registered for all CPUs thermal: cpu_cooling: get rid of 'allowed_cpus' thermal: cpu_cooling: merge frequency and power tables thermal: cpu_cooling: create structure for idle time stats thermal: cpu_cooling: get_level() can't fail thermal: cpu_cooling: don't store cpu_dev in cpufreq_dev thermal: cpu_cooling: 'freq' can't be zero in cpufreq_state2power() thermal: cpu_cooling: Rearrange struct cpufreq_cooling_device drivers/cpufreq/arm_big_little.c | 2 +- drivers/cpufreq/cpufreq-dt.c | 2 +- drivers/cpufreq/cpufreq_stats.c | 13 +- drivers/cpufreq/dbx500-cpufreq.c | 2 +- drivers/cpufreq/mt8173-cpufreq.c | 4 +- drivers/cpufreq/qoriq-cpufreq.c | 3 +- drivers/thermal/cpu_cooling.c | 530 ++++++++------------- drivers/thermal/imx_thermal.c | 22 +- drivers/thermal/ti-soc-thermal/ti-thermal-common.c | 22 +- include/linux/cpu_cooling.h | 32 +- include/linux/cpufreq.h | 14 + 11 files changed, 272 insertions(+), 374 deletions(-) -- 2.7.1.410.g6faf27b
