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.
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 user can allocate the protected buffer,
which is encrypted with the leverage of the arbitrary hardware
session.
rev23:
#09, #12
- Require user space to explicitly set recoverable flag to
false for protected context creation.
#13
- Add Cc of reviewers in commit message.
