PXP is an i915 componment, that helps to establish the hardware protected session and manage the status of the alive software session, as well as its life cycle.
This patch series is to allow the kernel space to create and manage a single hardware session (a.k.a default session or arbitrary session). So Mesa can allocate the protected buffer, which is encrypted with the leverage of the arbitrary hardware session.
