[PATCH 0/4] drm/xe: Implement device shutdown to make kexec work.

[Maarten Lankhorst]

Testcase:
kexec --reuse-cmdline --initrd=initrd.img -f vmlinuz

Because we don't shut down xe correctly, we cannot reload xe afterwards.
Implement device shutdown by performing a FLR, then we can load the device
cleanly again afterwards.

Some cleanups come first, those can be merged without the rest.

Maarten Lankhorst (4):
  drm/xe: Fix missing conversion to xe_display_pm_runtime_resume
  drm/xe: Remove runtime argument from display s/r functions
  drm/xe: Wire up device shutdown handler
  CI-only: Test if FLR is disabled?
