> Add DRM ioctl flags and a userptr address field so userspace can > request a blob backed by an existing process mapping. > > UAPI changes: > - Add guest-only VIRTGPU_BLOB_FLAG_USE_USERPTR and > VIRTGPU_BLOB_FLAG_USERPTR_RDONLY flags > - Add a userptr field to drm_virtgpu_resource_create_blob > > These flags select guest pin behavior in the ioctl. They are not > part of the virtio CREATE_BLOB wire ABI, so mask them out in > virtio_gpu_cmd_resource_create_blob(). > > Signed-off-by: Honglei Huang <[email protected]>
