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. Several major functional changes compared to v1: - Termination is issued on runtime resume as well. - Protected objects and contexts are marked as invalid on termination. Invalid contexts are reported to userspace via RESET_STATS. - Trying to flip an invalid objects results in a black frame. I've done more testing compared to v1 (initial IGTs from Alan will be hitting the ML soon), but I still haven't stress-tested with userspace applications, so there might be bugs. I'll make sure to run more testing and fix everything before merge, but in the meantime I wanted to get forward with the reviews given that the current tests give me enough confidence that this isn't completely broken.
