[Intel-gfx] [RFC-v5 00/21] Introduce Intel PXP component - Mesa single session

[Huang, Sean Z]

PXP (Protected Xe Path) is an i915 componment, 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.

[commit #1 - #13]
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.

[commit #14 - #21]
This patch series exposes ioctl so allow userspace to create,
set, and destroy one or multiple sessions. It will also provide
the communication chanel to TEE (Trusted Execution Environment)
for the protected hardware session creation.

v2:
    - modification based on code reivew feedbacks received
    - passing pxp instead of i915 as funciton argument
    - remove dead code only for multi-session
    - move the pxp init call from i915_drv.c to intel_gt.c
    - reove the tautology naming

v3:
    - rebase to latest drm-tip

v4:
    - Append the split non-mesa patch sereis (commit #14 - #21) into
      this patch series

v5:
    - include "intel_pxp.h" in intel_pxp_sm.h at commit #14 to fix
      the build problem.
