From 8bda1013ddb1dffdee7f9a1912f9845b9cf529cb Mon Sep 17 00:00:00 2001 From: Emily Deng Date: Fri, 12 Oct 2018 18:14:32 +0800 Subject: [PATCH] drm/amdgpu: Set the default value about gds vmid0 size For sriov, when first run windows guest, then run linux guest, the gds vmid0 size will be reset to 0 by windows guest. So if the value has been reset to 0, then set the value to the default value in linux guest. v2: Fixed value instead of reading mmGDS_VMID0_SIZE. v3: Set the default value of the switch.
