[PATCH 00/11] Add support for Blob resources feature |
Date: |
Tue, 30 Mar 2021 20:09:50 -0700 |
Enabling this feature would eliminate data copies from the resource
object in the Guest to the shadow resource in Qemu. This patch series
however adds support only for Blobs of type
VIRTIO_GPU_BLOB_MEM_GUEST with property VIRTIO_GPU_BLOB_FLAG_USE_SHAREABLE.
Most of the patches in this series are a rebased, refactored and bugfixed
versions of Gerd Hoffmann's patches located here:

TODO:
- Enable the combination virgl + blob resources
- Add support for VIRTGPU_BLOB_MEM_HOST3D blobs
