Subject: [Intel-gfx] [CI 1/2] drm/dsc: use rc_model_size from DSC config for PPS
Date: Mon, 20 Apr 2020 17:20:19 +0300 [thread overview]
Message-ID: <20200420142020.27340-1-jani.nikula@intel.com> (raw)
The PPS is supposed to reflect the DSC config instead of hard coding the
rc_model_size. Make it so.
Currently all users of drm_dsc_pps_payload_pack() hard code the size to
8192 also in the DSC config, so this change should have no impact, other
than allowing the drivers to use other sizes as needed.
