[Qemu-devel] [PATCH v7 0/8] Add vhost-user-gpu

Posted by Marc-André Lureau 10 weeks ago
Hi,

vhost-user allows to drive a virtio device in a seperate
process. After vhost-user-net, we have seen
vhost-user-{scsi,blk,crypto,input} added more recently.

This series, initially proposed ~3 years ago, time flies
(https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg01905.html)
contributes with vhost-user-gpu.

You may start a vhost-user-gpu with virgl rendering in a separate
process like this:

$ ./vhost-user-gpu --virgl -s vgpu.sock &
$ qemu...
  -chardev socket,id=chr,path=vgpu.sock
  -device vhost-user-vga,chardev=chr

Based-on: <20190513183325.8596-1-marcandre.lureau@redhat.com>

v7:
 - add "framed" replies to the vhost-user-gpu protocol
 - use GBM library instead of drm-vendor APIs
 - added "virtio-gpu: add a pixman helper header"

v6:
 - do not install vhost-user-input
 - install vhost-user-gpu and json file following the spec
 - fix the build when drm-intel-devel missing
 - rebase (& resend without already applied patches)

v5:
 - remove user-creatable version of vhost-user-backend
 - remove optinal management of sub-process in vhost-user-backend
 - removed daemonize/pid code
 - drop introduction of new input & gpu messages for PCI config space
   handling, instead use VHOST_USER_PROTOCOL_F_CONFIG
 - plain mem & udmabuf fallback for 2d rendering
 - rebased, kconfig-ify, rst-ify

Marc-André Lureau (8):
  vhost-user: add vhost_user_gpu_set_socket()
  virtio-gpu: add bswap helpers header
  virtio-gpu: add a pixman helper header
  util: compile drm.o on Linux
  contrib: add vhost-user-gpu
  virtio-gpu: split virtio-gpu, introduce virtio-gpu-base
  virtio-gpu: split virtio-gpu-pci & virtio-vga
  hw/display: add vhost-user-vga & gpu-pci
