Hi Rafael, This series tries to cleanup the code around transition-latency and its users. Some of the old legacy code, which may not make much sense now, is dropped as well. And some code consolidation is also done across governors. Based of: v4.13-rc1 Tested on: ARM64 Hikey board. I have pushed it here as well (which gets tested by kbuild test bot): git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/transition-latency V2->V3: - Rearranged patches to keep related stuff together - Introduce CPUFREQ_NO_AUTO_DYNAMIC_SWITCHING flag (Rafael) - Minor optimization in cpufreq_policy_transition_delay_us() and moved it to cpufreq.c (Rafael) - Allow dynamic switching for drivers which don't know their transition latency. V1->V2: - While we still get rid of the limitation of 10ms for using ondemand/conservative, but we preserve the earlier behavior where the transition latency set to CPUFREQ_ETERNAL would not allow use of ondemand/conservative governors. Thanks to Dominik for his feedback on that. -- viresh Viresh Kumar (9): cpufreq: governor: Drop min_sampling_rate cpufreq: Use transition_delay_us for legacy governors as well cpufreq: Cap the default transition delay value to 10 ms cpufreq: Don't set transition_latency for setpolicy drivers cpufreq: arm_big_little: Make ->get_transition_latency() mandatory cpufreq: Replace "max_transition_latency" with "dynamic_switching" cpufreq: schedutil: Set dynamic_switching to true cpufreq: Add CPUFREQ_NO_AUTO_DYNAMIC_SWITCHING cpufreq driver flag cpufreq: Allow dynamic switching with CPUFREQ_ETERNAL latency Documentation/admin-guide/pm/cpufreq.rst | 8 -------- drivers/cpufreq/arm_big_little.c | 10 ++++------ drivers/cpufreq/cpufreq-nforce2.c | 2 +- drivers/cpufreq/cpufreq.c | 34 ++++++++++++++++++++++++++++---- drivers/cpufreq/cpufreq_conservative.c | 6 ------ drivers/cpufreq/cpufreq_governor.c | 17 ++-------------- drivers/cpufreq/cpufreq_governor.h | 3 +-- drivers/cpufreq/cpufreq_ondemand.c | 12 ----------- drivers/cpufreq/elanfreq.c | 4 +--- drivers/cpufreq/gx-suspmod.c | 2 +- drivers/cpufreq/intel_pstate.c | 1 - drivers/cpufreq/longrun.c | 1 - drivers/cpufreq/pmac32-cpufreq.c | 7 +++++-- drivers/cpufreq/sa1100-cpufreq.c | 5 +++-- drivers/cpufreq/sa1110-cpufreq.c | 5 +++-- drivers/cpufreq/sh-cpufreq.c | 3 +-- drivers/cpufreq/speedstep-smi.c | 2 +- drivers/cpufreq/unicore2-cpufreq.c | 3 +-- include/linux/cpufreq.h | 18 ++++++++--------- kernel/sched/cpufreq_schedutil.c | 12 ++--------- 20 files changed, 65 insertions(+), 90 deletions(-) -- 2.13.0.71.gd7076ec9c9cb -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
