From 6abc0c8f8cf3e0c47707b01f027f9f9b9aa75646 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 30 Aug 2018 09:46:27 -0500 Subject: [PATCH] drm/amdgpu/gmc9: don't keep stolen memory on vega20 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Vega20 does not appear to be affected by the same issue as vega10. Enable the full stolen memory handling on vega20. 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.
