Subject: [Intel-gfx] [PATCH v4 11/23] drm/i915/adl_p: Add ddb allocation support
Date: Fri, 14 May 2021 20:10:23 -0700 [thread overview]
Message-ID: <20210515031035.2561658-12-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210515031035.2561658-1-matthew.d.roper@intel.com>
From: Vandita Kulkarni <vandita.kulkarni@intel.com>
On adlp the two mbuses have two display pipes and
two DBUFS, Pipe A and D on Mbus1 and Pipe B and C on
Mbus2. The Mbus can be joined and all the DBUFS can be
used on Pipe A or B.
