Subject: [Intel-gfx] [RFC-v3 21/26] drm/i915/pxp: Expose session state for display protection flip
Date: Tue, 1 Dec 2020 15:34:06 -0800 [thread overview]
Message-ID: <20201201233411.21858-22-sean.z.huang@intel.com> (raw)
In-Reply-To: <20201201233411.21858-1-sean.z.huang@intel.com>
Implement the intel_pxp_gem_object_status() to allow i915 display
querying the current PXP session state. In the design, display
should not perform protection flip on the protected buffers if
there is no PXP session alive.
