Subject: [PATCH v4 00/13] virtio-gpu: Add support for Blob resources feature (v4)
Date: Tue, 11 May 2021 15:47:06 -0700 [thread overview]
Message-ID: <20210511224719.387443-1-vivek.kasireddy@intel.com> (raw)
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:
https://gitlab.freedesktop.org/virgl/qemu/-/commits/virtio-gpu-next
v2:
- Moved dpy_gl_update from set_scanout to resource_flush
- Dropped the modifier
- Rebase and other minor refactoring
v3:
- Rebased on top of Gerd's virgl device split series
- Split the udmabuf helpers patch from the previous
version into two (Gerd)
- Added explicit flush feature (last 7 patches)
v4 (Gerd):
- Dropped explicit flush feature patches from the series
- Slightly refactored udmabuf helpers patch (#3) to introduce
and use blob and blob_size fields
- Fixed indentation issues and made other small changes in
set_scanout_blob patch (#12)
