Subject: [PATCH 03/13] drm/i915/guc: Update CTB response status definition
Date: Wed,  9 Jun 2021 21:36:39 -0700	[thread overview]
Message-ID: <20210610043649.144416-4-matthew.brost@intel.com> (raw)
In-Reply-To: <20210610043649.144416-1-matthew.brost@intel.com>

From: Michal Wajdeczko <michal.wajdeczko@intel.com>

Format of the STATUS dword in CTB response message now follows
definition of the HXG header. Update our code and remove any
obsolete legacy definitions.

GuC: 55.0.0
