A customer issue was recently discovered and in the process a
gap in i915's PXP interaction with HW+FW architecure was also
realized. This series adds those missing pieces.
The patches explain the details.
Changes from prior revs:
v1: - Dont need to teardown non arbitration sessions (Juston).
- Fix builds when PXP is enabled in config (Alan/CI-build)
- Fix the broken pm-suspend-resume symmetry when we do this
pxp-session-teardown during i915s pm_suspend_prepare by
ensuring the init is done during i915s pm_resume_complete.
Alan Previn (3):
drm/i915/pxp: Invalidate all PXP fw sessions during teardown
drm/i915/pxp: Trigger the global teardown for before suspending
drm/i915/pxp: Pxp hw init should be in resume_complete
