Subject: [Intel-gfx] [RFC-v8 00/23] Introduce Intel PXP component - Mesa single session
Date: Fri, 11 Dec 2020 01:04:34 -0800 [thread overview]
Message-ID: <20201211090457.32674-1-sean.z.huang@intel.com> (raw)
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 user can allocate the protected buffer,
which is encrypted with the leverage of the arbitrary hardware
session.
[commit #14 - #23]
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.
v6:
- Fix the null pointer arb_session access bug in intel_pxp_arb.c in
"04 [RFC-v5] drm/i915/pxp: Create the arbitrary session after boot"
v7:
- Use list_for_each_entry_safe instead of list_for_each_entry
v8:
- Add MEI vtag support for PXP multi-session usage
