H A D | vce_v3_0.c | 5bbc553a Wed May 06 14:20:41 CDT 2015 Leo Liu <leo.liu@amd.com> drm/amdgpu: implement VCE two instances support
VCE 3.0 has two indentical instances in the engine, they share the same registers name in differrent memory block distinguished by the grbm_gfx_index, we set to master instance after init, it will dispatch task to slave instance. These two instances will share the same firmware, but have their own stacks and heaps.
v2: add mutex for using grbm_gfx_index
