Hello Rafael,
this patchset is a new version of the cpufreq SW coordinated CPU bug fix.
That's basically the v4 rebased on linux-pm's linux-next tree, split in 5
patches for readability and with the bug fixed also in the "conservative"
governor.
Regards,
Fabio
Changes:
v5
- rebased/reimplemented on linux-next
- split hotplug code on a separate patch
- split ondemand/conservative specific fixes on separate patches
v4
- moved update_sampling rate code on separate patch
- simplified dbs_sw_coordinated_cpus
- reworked timer handling for code readability, now:
* do_dbs_timer() [-> dbs_timer_coordinated()] -> dbs_timer_update()
- simplified cpu_callback cases
v3
- original submission
Fabio Baltieri (4):
cpufreq: star/stop cpufreq timers on cpu hotplug
cpufreq: ondemand: call dbs_check_cpu only when necessary
cpufreq: conservative: call dbs_check_cpu only when necessary
cpufreq: ondemand: use all CPUs in update_sampling_rate
