With: root@darkstar:~# cat /sys/kernel/debug/vgaswitcheroo/switch 0:DIS: :DynOff:0000:01:00.0 1:IGD:+:Pwr:0000:00:02.0 I still get: root@darkstar:~# cat /sys/kernel/debug/dri/64/radeon_pm_info default engine clock: 575000 kHz current engine clock: 210280 kHz default memory clock: 900000 kHz current memory clock: 00 kHz voltage: 825 mV PCIE lanes: 16 Looking at the patch, I think I should get 'Chip powered off'.
