PXP (Protected Xe Path) is an i915 component, available on GEN12+, that helps to establish the hardware protected session and manage the status of the alive software session, as well as its life cycle.
Changes from v6:
- reworked object invalidation to be based on PXP instance instead of lists, so we can drop the locking (Daniel).
- just keep a wakeref while a protected context is around (Daniel).
- don't add a new flag to RESET_STATS, just increase the guilty count as if we had a hang (Daniel).
- add kerneldoc (Daniel). Added it all in one go at the end so it is easier to review.
- change location for the display blackscreen check (Juston).
- fix an issue with pxp component removal.
