K J Petrie (kernel.b...@kjpetrie.co.uk) changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |CODE_FIX --- Comment #11 from K J Petrie (kernel.b...@kjpetrie.co.uk) --- I decided to compile 5.6.6 with CONFIG_PM_ADVANCED_DEBUG. To my amazement, this gave me: # uname -r 5.6.6 # cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:01:00.0 2:DIS-Audio: :DynOff:0000:01:00.1 (!!!!!!) (GPU) # cat /sys/bus/pci/devices/0000\:01\:00.0/power/control auto # cat /sys/bus/pci/devices/0000\:01\:00.0/power/runtime_status suspended cat /sys/bus/pci/devices/0000\:01\:00.0/power/runtime_usage 0 # cat /sys/bus/pci/devices/0000\:01\:00.0/power/runtime_active_kids 0 (HDA) # cat /sys/bus/pci/devices/0000\:01\:00.1/power/control auto # cat /sys/bus/pci/devices/0000\:01\:00.1/power/runtime_status suspended # cat /sys/bus/pci/devices/0000\:01\:00.1/power/runtime_usage 0 # cat /sys/bus/pci/devices/0000\:01\:00.1/power/runtime_active_kids 0 So, either enabling CONFIG_PM_ADVANCED_DEBUG affects this or it's fixed in the latest kernels. As a quick check I installed the distribution's latest kernel: # uname -r 5.5.19-pclos1 [root@master2 ken]# cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:01:00.0 2:DIS-Audio: :DynOff:0000:01:00.1 So it looks as if it was fixed in the 5.5 kernels. However, both the 5.5 (distro) and 5.6 (mainline) kernels emit a terrible clattering sound during services start up. I'm unsure whether that's coming from the speakers, HDD or optical drive. If the former, it's just a nuisance, if one of the latter it's not good news. I hope that's not related to the fix! -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
