Subject: [Intel-gfx] [PATCH 4/4] drm/i915/mtl: Skip pcode qgv restrictions for MTL
Date: Fri, 17 Mar 2023 17:58:52 -0700	[thread overview]
Message-ID: <20230318005852.2303937-5-radhakrishna.sripada@intel.com> (raw)
In-Reply-To: <20230318005852.2303937-1-radhakrishna.sripada@intel.com>

Communicating QGV points restriction to PUnit happens via PM Demand
instead of the Pcode mailbox in the previous platforms. GV point
restriction is handled by the PM demand code.
