Subject: [Intel-gfx] [PATCH v2 8/8] drm/i915: Rename QGV request/response bits
Date: Wed,  9 Mar 2022 18:49:48 +0200	[thread overview]
Message-ID: <20220309164948.10671-9-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20220309164948.10671-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Name all the ICL_PCODE_SAGV_DE_MEM_SS_CONFIG request/response
bits in a manner that we can actually understand what they're
doing.
