Subject: [PATCH 19/20] drm/i915/guc: Early initialization of GuC send registers
Date: Wed,  2 Jun 2021 22:16:29 -0700	[thread overview]
Message-ID: <20210603051630.2635-20-matthew.brost@intel.com> (raw)
In-Reply-To: <20210603051630.2635-1-matthew.brost@intel.com>

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

Base offset and count of the GuC scratch registers, used for
sending MMIO messages to GuC, can be initialized earlier with
other GuC members that also depends on platform.
