Subject: [Intel-gfx] [PATCH 2/4] drm/i915/guc: Improved reporting when GuC fails to load
Date: Fri, 25 Sep 2020 16:26:35 -0700	[thread overview]
Message-ID: <20200925232637.1968039-3-John.C.Harrison@Intel.com> (raw)
In-Reply-To: <20200925232637.1968039-1-John.C.Harrison@Intel.com>

From: John Harrison <John.C.Harrison@Intel.com>

Rather than just saying 'GuC failed to load: -110', actually print out
the GuC status register and break it down into the individual fields.

Signed-off-by: John Harrison <John.C.Harrison@Intel.com>
