+Subject: [PATCH 0221/2940] drm/amdgpu/gmc9: don't keep stolen memory on Raven
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Raven does not appear to be affected by the same issue
+as vega10. Enable the full stolen memory handling on
+Raven. Reserve the appropriate size at init time to avoid
+display artifacts and then free it at the end of init once
+the new FB is up and running.
