Maulik Shah 11cfbcfeac pmdomain: governor: Consider CPU latency tolerance from pm_domain_cpu_gov ... [ Upstream commit 500ba33284416255b9a5b50ace24470b6fe77ea5 ] pm_domain_cpu_gov is selecting a cluster idle state but does not consider latency tolerance of child CPUs. This results in deeper cluster idle state whose latency does not meet latency tolerance requirement. Select deeper idle state only if global and device latency tolerance of all child CPUs meet. Test results on SM8750 with 300 usec PM-QoS on CPU0 which is less than domain idle state entry (2150) + exit (1983) usec latency mentioned in devicetree, demonstrate the issue. # echo 300 > /sys/devices/system/cpu/cpu0/power/pm_qos_resume_latency_us Before: (Usage is incrementing) ====== # cat /sys/kernel/debug/pm_genpd/power-domain-cluster0/idle_states State Time Spent(ms) Usage Rejected Above Below S0 29817 537 8 270 0 # cat /sys/kernel/debug/pm_genpd/power-domain-cluster0/idle_states State Time Spent(ms) Usage Rejected Above Below S0 30348 542 8 271 0 After: (Usage is not incrementing due to latency tolerance) ====== # cat /sys/kernel/debug/pm_genpd/power-domain-cluster0/idle_states State Time Spent(ms) Usage Rejected Above Below S0 39319 626 14 307 0 # cat /sys/kernel/debug/pm_genpd/power-domain-cluster0/idle_states State Time Spent(ms) Usage Rejected Above Below S0 39319 626 14 307 0 Signed-off-by: Maulik Shah <maulik.shah@oss.qualcomm.com> Fixes: e94999688e ("PM / Domains: Add genpd governor for CPUs") Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20250709-pmdomain_qos-v2-1-976b12257899@oss.qualcomm.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> [ replaced cpu_latency_qos_limit() with pm_qos_request(PM_QOS_CPU_DMA_LATENCY) ] Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2025-08-28 16:21:34 +02:00
