Subject: [Intel-gfx] [PATCH v2 06/22] drm/i915/rkl: Update memory bandwidth parameters
Date: Mon, 4 May 2020 15:52:11 -0700 [thread overview]
Message-ID: <20200504225227.464666-7-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20200504225227.464666-1-matthew.d.roper@intel.com>
The RKL platform has different memory characteristics from past
platforms. Update the values used by our memory bandwidth calculations
accordingly.
