I figured the easiest thing I could do right now was adding some printk() to the code to have an overview of what is happening in dmesg -H | grep radeonpm. After booting up with no X I see this: [ +0,000016] radeonpm: runtime_idle [ +4,000483] radeonpm: runtime_suspend After starting X this is added: [Jan31 19:04] radeonpm: runtime_resume [ +1,126688] radeonpm: runtime_idle [ +0,000203] radeonpm: runtime_idle [ +0,000400] radeonpm: runtime_idle [ +0,000232] radeonpm: runtime_idle But then it never does anything again. After this, I did the usual xrandr --setprovideroffloadsink radeon Intel and started and exited DRI_PRIME=1 glxgears and stuff, but nothing with radeonpm was printed to the log again. After a while I tried exiting X and sure enough, another line: [ +2,368895] radeonpm: runtime_suspend And after starting X for the second time: [ +19,119650] radeonpm: runtime_resume [ +1,131037] radeonpm: runtime_idle And then... nothing with radeonpm again. I have read a bit in the Documentation/power/runtime_pm.txt and maybe I did not catch it but I haven't really seen when you call pm_runtime_put_autosuspend whether it is supposed to eventually call back radeon_pmops_runtime_suspend but I would think that's what it does, right? So that just never happens until X is quit. After boot with no X running I see this with for i in /sys/class/drm/card0/device/power/*; do echo "$i: $(cat $i)"; done /sys/class/drm/card0/device/power/async: enabled /sys/class/drm/card0/device/power/autosuspend_delay_ms: 5000 /sys/class/drm/card0/device/power/control: auto /sys/class/drm/card0/device/power/runtime_active_kids: 0 /sys/class/drm/card0/device/power/runtime_active_time: 13260 /sys/class/drm/card0/device/power/runtime_enabled: enabled /sys/class/drm/card0/device/power/runtime_status: suspended /sys/class/drm/card0/device/power/runtime_suspended_time: 218426 /sys/class/drm/card0/device/power/runtime_usage: 0 [snipped some wakeup* stuff] The GPU is off, fan is not running, etc. After starting X I see this: /sys/class/drm/card0/device/power/async: enabled /sys/class/drm/card0/device/power/autosuspend_delay_ms: 5000 /sys/class/drm/card0/device/power/control: auto /sys/class/drm/card0/device/power/runtime_active_kids: 0 /sys/class/drm/card0/device/power/runtime_active_time: 185230 /sys/class/drm/card0/device/power/runtime_enabled: enabled /sys/class/drm/card0/device/power/runtime_status: active /sys/class/drm/card0/device/power/runtime_suspended_time: 226856 /sys/class/drm/card0/device/power/runtime_usage: 0 runtime_status is always active in X... -- You are receiving this mail because: You are watching the assignee of the bug.
