Subject: [PATCH AUTOSEL 5.2 23/23] drm/i915/icl: whitelist PS_(DEPTH|INVOCATION)_COUNT
Date: Tue,  3 Sep 2019 12:24:24 -0400	[thread overview]
Message-ID: <20190903162424.6877-23-sashal@kernel.org> (raw)
In-Reply-To: <20190903162424.6877-1-sashal@kernel.org>

From: Lionel Landwerlin <lionel.g.landwerlin@intel.com>

[ Upstream commit cf8f9aa1eda7d916bd23f6b8c226404deb11690c ]

The same tests failing on CFL+ platforms are also failing on ICL.
Documentation doesn't list the
WaAllowPMDepthAndInvocationCountAccessFromUMD workaround for ICL but
applying it fixes the same tests as CFL.

v2: Use only one whitelist entry (Lionel)
