From 2cf6dd9cc5191ef9aec4f22cd64df8dc67e31c6d Mon Sep 17 00:00:00 2001 From: Trigger Huang Date: Wed, 7 Nov 2018 11:30:57 +0800 Subject: [PATCH] drm/amdgpu: disable page queue on Vega10 SR-IOV VF MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, SDMA page queue is not used under SR-IOV VF, and this queue will cause ring test failure in amdgpu module reload case. So just disable it.
