From 0808210478c76606c12bb475b3272b7780240812 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Tue, 10 Apr 2018 13:42:38 +0200 Subject: [PATCH] drm/amdgpu: revert "Don't change preferred domian when fallback GTT v6" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This reverts commit 7d1ca1325260a9e9329b10a21e3692e6f188936f. Makes fallback handling to complicated. This is just a feature for the GEM interface and shouldn't leak into the core BO create function. The intended change to preserve the preferred domains is implemented in a follow up patch.
