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 Tested with: https://patchwork.freedesktop.org/series/87570/ Cc: Gaurav Kumar
