Subject: [Intel-gfx] [CI 2/2] drm/i915/dsc: configure hardware using specified rc_model_size
Date: Mon, 20 Apr 2020 17:20:20 +0300 [thread overview]
Message-ID: <20200420142020.27340-2-jani.nikula@intel.com> (raw)
In-Reply-To: <20200420142020.27340-1-jani.nikula@intel.com>
The rc_model_size is specified in the DSC config, and the hardware
programming should respect that instead of hard coding a value of 8192.
Regardless, the rc_model_size in DSC config is currently hard coded to
the same value, so this should have no impact, other than allowing the
use of other sizes as needed.
