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 minor changes and fixes, but the main changes in v4 are: - Rebased to new create_ext ioctl implementation - Default kconfig option is now N. - The default session is now only started when protected objects are submitted via execbuf.
