David Francis db0ec806d1 plugin/amdgpu: Add handling for amdgpu drm buffer objects ... Buffer objects held by the amdgpu drm driver are checkpointed with the new BO_INFO and MAPPING_INFO ioctls/ioctl options. Handling is in amdgpu_plugin_drm.h Handling of imported buffer objects may require dmabuf fds to be transferred between processes. These occur over fdstore, with the handle-fstore id relationships kept in shread memory. There is a new plugin callback: RESTORE_INIT to create the shared memory. During checkpoint, track shared buffer objects, so that buffer objects that are shared across processes can be identified. During restore, track which buffer objects have been restored. Retry restore of a drm file if a buffer object is imported and the original has not been exported yet. Skip buffer objects that have already been completed or cannot be completed in the current restore. So drm code can use sdma_copy_bo, that function no longer requires kfd bo structs Update the protobuf messages with new amdgpu drm information.
