Kernels >= 7.2 keep the firmware's S4/S5 wake bit on GPIO pin 18, so the Steam Machine starts again right after powering off. Steam Machine support now builds a DKMS module (patches/steamify-fremont-poweroff.c) that clears it before power-off, for every kernel. The kernel pin is no longer ticked by default. Module sources and patches move to patches/, embedded by the single-file build.

Steam Machine CEC: find amdgpu's HDMI port with a single CEC port.
|
|
|
|
amdgpu registers its HDMI notifier without a port name, which only matches
|
|
the driver's named lookup ("Port C") if the CEC driver loaded first; amdgpu
|
|
loads from the initramfs, so it never does and /dev/cec0 stays at f.f.f.f.
|
|
With a single CEC port, look the notifier up by device alone.
|

Applies to Valve's drivers/media/cec/platform/cros-ec/cros-ec-cec.c

(evlaV/linux-integration 10c8c880, see CEC_DRIVER_URL in lib/cec.sh).
