Subject: [PATCH 1/9] drm/i915: Accept alloc_size == blocks
Date: Tue, 12 Mar 2019 22:58:36 +0200 [thread overview]
Message-ID: <20190312205844.6339-2-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20190312205844.6339-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
If the minimum required ddb space for all the planes equals the
total ddb space available we are allowed to use the relevant
watermark level.
