| H A D | amdgpu.h | fa7c7939 Wed Nov 22 08:55:21 CST 2017 Michel Dänzer <michel.daenzer@amd.com> drm/amdgpu: Use unsigned ring indices in amdgpu_queue_mgr_map
This matches the corresponding UAPI fields. Treating the ring index as
signed could result in accessing random unrelated memory if the MSB was
set.

ids v6")
