From 7fdf165a52505392eb059902b0df55e79a45c25f Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Wed, 29 Nov 2017 17:26:56 +0100 Subject: [PATCH] drm/radeon: remove init of CIK VMIDs 8-16 for amdkfd MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit VMIDs 8-16 in Kaveri were reserved for use by the amdkfd driver. Because we removed amdkfd support from radeon, those VMIDs are now used by radeon and are initialized by radeon. This patch removes the function that initialized those VMIDs for amdkfd use. This initialization overridden the radeon initialization and caused GPU faults and GUI crashed.
