Subject: [PATCH 01/24] HAX to make DSC work on the icelake test system
Date: Fri,  4 Oct 2019 13:34:51 +0200	[thread overview]
Message-ID: <20191004113514.17064-2-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20191004113514.17064-1-maarten.lankhorst@linux.intel.com>

DSC is available on the display emulator, but not set in DPCD.
Override the entries to allow bigjoiner testing.
