Subject: [PATCH 10/10] amdgpu: sync amdgpu_drm.h with the kernel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
v1:
* User might want to query the maximum number of UVD
instances supported by firmware. In addition to that,
if there are multiple applications using UVD handles
at the same time, he might also want to query the
currently used number of handles.
For this we add a new query AMDGPU_INFO_NUM_HANDLES
and a new struct drm_amdgpu_info_num_handles to
get these values.
v2:
* Generated using make headers_install.
* Generated from linux-stable/master commit
