[PATCH V2 0/3] PM / OPP: Parse opp-supported-hw/opp-<prop>-<name> bindings

by Viresh Kumar

Hi Rafael/Stephen, The bindings are reviewed now and here is the code to parse them. The first patch is a minor cleanup and other two contain the real stuff. Rebased over: v4.4-rc1 + OPP debugfs support patch. Tested-on: Exynos 5250, dual core A15. V1->V2: - Fixed locking - NUL terminate strings instead of sprintf - Remove NULL checkers for the routines - constify 'versions' - s/EINVAL/EBUSY - updated comments over routines - Use of_property_read_u32_index() instead of allocating arrays - remove dev_opp for failures Viresh Kumar (3): PM / OPP: Add missing doc comments PM / OPP: Parse 'opp-supported-hw' binding PM / OPP: Parse 'opp-<prop>-<name>' bindings drivers/base/power/opp/core.c | 301 +++++++++++++++++++++++++++++++++++++++--- drivers/base/power/opp/opp.h | 11 +- include/linux/pm_opp.h | 22 +++ 3 files changed, 318 insertions(+), 16 deletions(-) -- 2.6.2.198.g614a2ac

[PATCH V2 00/10] cpufreq: governor: Avoid invalid state-transitions

by Viresh Kumar

Hi Rafael/Preeti, This is another attempt to fix the crashes reported by Preeti. They work quite well for me now, and I hope they would work well for Preeti as well :) So, patches [1-7,9] are already Reviewed by Preeti. The first 5 patches are minor cleanups, 6th & 7th try to optimize few things to make code less complex. Patches 8-10 actually solve (or try to solve :)) the synchronization problems, or the crashes I was getting. V1->V2: - 7/11 is dropped and only 8/11 is updated, which is 8/10 now. - Avoid taking the same mutex in both cpufreq_governor_dbs() and work-handler as that has given us some locdeps, classic ABBA stuff. - And so timer_mutex, responsible for synchronizing governor work-handlers is kept as is. - Later patches are almost same with minor updates. - Invalid state-transitions are sensed better now with improved checks. - I have run enough tests on my exynos dual core board and failed to crash at all. Not that I wanted to crash :) Rebased over pm/bleeeding-edge. Viresh Kumar (10): cpufreq: governor: Name delayed-work as dwork cpufreq: governor: Drop unused field 'cpu' cpufreq: governor: Rename 'cpu_dbs_common_info' to 'cpu_dbs_info' cpufreq: governor: name pointer to cpu_dbs_info as 'cdbs' cpufreq: governor: rename cur_policy as policy cpufreq: governor: Keep single copy of information common to policy->cpus cpufreq: governor: split out common part of {cs|od}_dbs_timer() cpufreq: governor: Avoid invalid states with additional checks cpufreq: governor: Don't WARN on invalid states cpufreq: propagate errors returned from __cpufreq_governor() drivers/cpufreq/cpufreq.c | 22 ++-- drivers/cpufreq/cpufreq_conservative.c | 25 ++--- drivers/cpufreq/cpufreq_governor.c | 196 ++++++++++++++++++++++++--------- drivers/cpufreq/cpufreq_governor.h | 40 ++++--- drivers/cpufreq/cpufreq_ondemand.c | 67 ++++++----- 5 files changed, 220 insertions(+), 130 deletions(-) -- 2.4.0

[PATCH 0/6] cpufreq: governor: replace per-cpu delayed work with timers

by Viresh Kumar

Hi Rafael, As suggested by you yesterday, I have updated the governor core to keep per-cpu timers and a shared work for the entire policy. More details are present in the changelogs, hope they are somewhat better this time. I have tested it with the test-suite, that I created sometime back while fixing locking issues in governors.. Tried all kind of stuff in parallel that could have broken it (those are the testcases that separate people reported over time, around governors). It works fine. The first one is a bug fix really, which I noticed today only :), next three are minor cleanups to prepare for the big change. Fourth one is the main patch that does the conversion and the final one is cherry-picked from the last series as that was still relevant. This is rebased over: pm/bleeding-edge + "[PATCH V4] cpufreq: governor: Quit work-handlers early if governor is stopped", which I sent separately this morning with the changelog you suggested. Please see if this meets your expectations or not :) Viresh Kumar (6): cpufreq: ondemand: Update sampling rate only for concerned policies cpufreq: ondemand: Work is guaranteed to be pending cpufreq: governor: Pass policy as argument to ->gov_dbs_timer() cpufreq: governor: initialize/destroy timer_mutex with 'shared' cpufreq: governor: replace per-cpu delayed work with timers cpufreq: ondemand: update update_sampling_rate() to make it more efficient drivers/cpufreq/cpufreq_conservative.c | 6 +- drivers/cpufreq/cpufreq_governor.c | 145 +++++++++++++++++++-------------- drivers/cpufreq/cpufreq_governor.h | 23 ++++-- drivers/cpufreq/cpufreq_ondemand.c | 66 ++++++++++----- 4 files changed, 147 insertions(+), 93 deletions(-) -- 2.6.2.198.g614a2ac
