Subject: [PATCH] drm/i915/guc: Print CTL params passed to Guc
Date: Fri, 15 Jun 2018 14:10:56 +0000	[thread overview]
Message-ID: <20180615141056.42108-1-michal.wajdeczko@intel.com> (raw)

While debugging we may want to examine params passed to GuC.
Print them all if config I915_DEBUG_GUC is enabled.
