From aa2b2e2822831d78a283edb12cf8b7da21bdd0ed Mon Sep 17 00:00:00 2001 From: Chunming Zhou Date: Tue, 17 Apr 2018 11:52:53 +0800 Subject: [PATCH] drm/amdgpu: set preferred_domain independent of fallback handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When GEM needs to fallback to GTT for VRAM BOs we still want the preferred domain to be untouched so that the BO has a cance to move back to VRAM in the future.
