Does this depend on some other patch? I'm getting a build failure: drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c: In function ‘gmc_v7_0_init_compute_vmid’: drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c:2038:19: error: ‘MTYPE_NONCACHED’ undeclared (first use in this function) sh_mem_config |= MTYPE_NONCACHED << SH_MEM_CONFIG__DEFAULT_MTYPE__SHIFT; ^ drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c:2038:19: note: each undeclared identifier is reported only once for each function it appears in
