[PATCH v8 00/17] drm/i915: Introduce Intel PXP

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.

The main change from v7 is that we no longer increase the guilty count
when a context is banned due to PXP invalidation
