Subject: [Intel-gfx] [PATCH 07/37] drm/i915/rkl: Add initial workarounds
Date: Wed, 20 May 2020 17:37:33 -0700 [thread overview]
Message-ID: <20200521003803.18936-8-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20200521003803.18936-1-lucas.demarchi@intel.com>
From: Matt Roper <matthew.d.roper@intel.com>
RKL and TGL share some general gen12 workarounds, but each platform also
has its own platform-specific workarounds.
