Subject: [PATCH 4/4] drm/i915: Drop WaIncreaseLatencyIPCEnabled/1140 for cnl
Date: Thu, 31 Jan 2019 09:42:16 +0200 [thread overview]
Message-ID: <20190131074216.3994-4-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20190131074216.3994-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Drop WaIncreaseLatencyIPCEnabled/Display w/a #1140 for
early cnl steppings. Also switch the kbl/cfl case to check
for IS_GEN9_BC() for brevity. It ends up being the same thing
because IPC is disabled on SKL due to w/a #0477.
