drm/xe/display: Add missing HPD interrupt enabling during non-d3cold RPM resume

2024-10-29T14:12:56Z

Atm the display HPD interrupts that got disabled during runtime suspend, are re-enabled only if d3cold is enabled. Fix things by also re-enabling the interrupts if d3cold is disabled.

drm/xe/display: Separate the d3cold and non-d3cold runtime PM handling

2024-10-29T14:12:56Z

For clarity separate the d3cold and non-d3cold runtime PM handling. The only change in behavior is disabling polling later during runtime resume. This shouldn't make a difference, since the poll disabling is handled from a work, which could run at any point wrt. the runtime resume handler. The work will also require a runtime PM reference, syncing it with the resume handler.

drm/xe: Remove runtime argument from display s/r functions

2024-10-29T14:12:55Z

The previous change ensures that pm_suspend is only called when suspending or resuming. This ensures no further bugs like those in the previous commit.

The commit 'b1d90a86 ("drm/xe: Use the encoder suspend helper also used by the i915 driver")' didn't do anything wrong. It actually fixed a critical bug, because the encoder_suspend was never getting actually called because it was returning if (has_display(xe)) instead of if (!has_display(xe)). However, this ended up introducing the encoder suspend calls in the runtime routines as well, causing the circular locking dependency.
