I.e., at some point in the future if we support pre-emption in general, would we set this flag even when SR-IOV is not enabled? I.e., is userspace using this as a check for pre-emption or sr-iov? If it's the latter, I'd suggest changing the name of the flag to something with SR-IOV. If it's the former, then the patch is: Reviewed-by: Alex Deucher <alexander.deucher at amd.com> > dev_info.virtual_address_offset = > AMDGPU_VA_RESERVED_SIZE; > dev_info.virtual_address_max = (uint64_t)adev- > >vm_manager.max_pfn * AMDGPU_GPU_PAGE_SIZE; > dev_info.virtual_address_alignment = max((int)PAGE_SIZE, > AMDGPU_GPU_PAGE_SIZE); > diff --git a/include/uapi/drm/amdgpu_drm.h > b/include/uapi/drm/amdgpu_drm.h > index 667e9bc..49d2404 100644 > --- a/include/uapi/drm/amdgpu_drm.h > +++ b/include/uapi/drm/amdgpu_drm.h > @@ -440,6 +440,7 @@ struct drm_amdgpu_cs_chunk_data { > * > */ > #define AMDGPU_IDS_FLAGS_FUSION 0x1 > +#define AMDGPU_IDS_FLAGS_PREEMPTION 0x2 > > /* indicate if acceleration can be working */ > #define AMDGPU_INFO_ACCEL_WORKING 0x00 > -- > 1.9.1 > > _______________________________________________ > amd-gfx mailing list > amd-gfx at lists.freedesktop.org > https://lists.freedesktop.org/mailman/listinfo/amd-gfx
