PXP (Protected Xe Path) is an i915 component, available on GEN12i and newer platforms, 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 v8: - comments/docs improvements - remove rpm put race (pxp_inval vs context_close) - don't call pxp_invalidate on rpm suspend because it's redundant
