drm/amdkfd: Get unique_id dynamically v2
Instead of caching the value during amdgpu_device_init, just call the function directly. This avoids issues where the unique_id hasn't been saved by the time that KFD's topology snapshot is done (e.g. Arcturus). KFD's topology information from the amdgpu_device was initially cached at KFD initialization due to amdkfd and amdgpu being separate modules. Now that they are combined together, we can directly call the functions that we need and avoid this unnecessary duplication and complexity. As a side-effect of this change, we also remove unique_id=0 for CPUs, which is obviously not unique. v2: Drop previous patch printing unique_id in hex Signed-off-by: Kent Russell <kent.russell@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
