From 95010ba79baae078c2bcabda49cf564261d0b796 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 30 Aug 2018 09:44:31 -0500 Subject: [PATCH] drm/amdgpu/gmc9: don't keep stolen memory on vega12 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit vega12 does not appear to be affected by the same issue as vega10. Enable the full stolen memory handling on vega12. 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.
