Subject: [Intel-gfx] [PXP CLEAN PATCH v06 22/27] drm/i915/pxp: Expose session state for display protection flip
Date: Fri, 13 Nov 2020 16:37:11 -0800	[thread overview]
Message-ID: <20201114003716.4875-22-sean.z.huang@intel.com> (raw)
In-Reply-To: <20201114003716.4875-1-sean.z.huang@intel.com>

From: "Huang, Sean Z" <sean.z.huang@intel.com>

Implement the intel_pxp_gem_object_status() to allow ring0 i915
display querying the current PXP session state. In the design,
ring0 display should not perform protection flip on the protected
buffers if there is no PXP session alive.
