[RFC] sched: fair: Don't update CPU frequency too frequently

by Viresh Kumar

update_load_avg() is the heaviest caller of the cpufreq utilization callbacks right now and it runs too frequently from various parts of the fair scheduler. It may not be optimal to update the CPU frequency that frequently though. We are more concerned about the events when the CPU utilization changes sharply and that mostly happens when a task gets attached/detached to/from a runqueue. Perhaps we aren't that concerned about the case when the utilization changes gradually (small delta) due the time a task gets to run and updating the CPU frequency at the tick rate should be good enough in that case. Sometimes update_load_avg() gets called right before migrating a task to a new CPU and that can steal the chance of updating the frequency when we actually needed it (i.e. after util_avg is updated with the contributions of the migrated task). This can happen because the cpufreq governors change the frequency only once in a fixed period of time (i.e. rate_limit_us for the schedutil governor). The fair scheduler already calls the utilization hooks from attach/detach paths and that takes care of the most important case we are concerned about. This patch relocates the call to utilization hook from update_cfs_rq_load_avg() to task_tick_fair(). Testing: Platform: Skylake, Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz. Quad core (8 threads). Distribution: Ubutnu 16.04 with cmdline intel_pstate=passive. Based over 4.12-rc3. All the below tests were run 3 times with and without this change over 4.12-rc3 and the average of all the runs is shown here (RESULT). The number of times the schedutil hook is called during the tests is also present in the table (UPDATE-COUNT). Bench: - pipe-test Command: perf bench sched pipe 4.12-rc3 4.12-rc3 + this patch Change -------- --------------------- ---------- RESULT 4.21 3.68 - 12.53 % UPDATE-COUNT 5405 886 - 83 % - Hackbench Command: sync; sleep 1; for i in {1..20}; do sleep 2; \ hackbench -P -g 1 | grep Time; done 4.12-rc3 4.12-rc3 + this patch Change -------- --------------------- ---------- RESULT 0.00925 0.00853 - 7.75 % UPDATE-COUNT 10342 1925 - 81 % - ebizzy Command: ebizzy -t N -S 20 4.12-rc3 4.12-rc3 + this patch Change -------- --------------------- ---------- RESULT (N=8) 270221 247841 - 8 % RESULT (N=16) 252692 249839 - 1.1 % RESULT (N=24) 251151 254114 + 1.1 % RESULT (N=32) 249274 250115 + 0.3 % UPDATE-COUNT 41964 40279 - 4 % - cyclictest (with latency) Command: cyclictest -q -t N -i 10000 --latency=1000000 -D 20 4.12-rc3 4.12-rc3 + this patch Change -------- --------------------- ---------- RESULT (N=8) 326 332 + 1.75 % RESULT (N=16) 297 328 + 10 % RESULT (N=24) 288 317 + 9.9 % RESULT (N=32) 268 313 + 17 % UPDATE-COUNT 28949 313 - 98.6 % Some more investigation (with ftrace) was done to check the cause of regression in this case (as the below test doesn't have the same results without latency). o The number of time we went into a cpuidle state and came out of it is almost same with both the images. o The average time between sched_waking and sched_switch traces for the cyclictest threads is 19.8 us with rc3 and 13.5 us with this patch. And so the response to the threads is actually better with this patch. o Need more suggestions to verify why the regression is there. - cyclictest (without latency) Command: cyclictest -q -t N -i 10000 --latency=0 -D 20 4.12-rc3 4.12-rc3 + this patch Change -------- --------------------- ---------- RESULT (N=8) 16.34 8.87 - 45.78 % RESULT (N=16) 13.91 6.41 - 54 % RESULT (N=24) 12.42 9.1 - 26.77 % RESULT (N=32) 13 3.34 - 74 % UPDATE-COUNT 26000 350 - 98.6 % Note: Most of the MAX values with rc3 were between 10-30 and that with this patch were between 2-20. There were few random high values (100-400) though with both the images and are discarded to get the averages. Summary: o The number of times cpufreq utilization callbacks were called (UPDATE-COUNT) during the tests has come down heavily (81-96 %), except for ebizzy. And that's a lot of code removed from scheduler's hot path. o pipe-test and hackbench have shown a clear improvement with the patch. o ebizzy has shown a regression (specially at N=8). Though during some individual tests, rc3 also reported low numbers as compared to the kernel with this patch. o cyclictest with 0 latency (i.e. no deeper idle states) shows clear improvement, while with latency=1000000 there is considerable regression.
