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 changes in v5 are:

- Rebased to new proto_ctx implementation.

- Squashed all uapi changes in a single patch and slightly updated docs.

- Now handling mei_pxp loading after i915
