[Qemu-devel] [PATCH v5 00/12] vhost-user-backend & vhost-user-input

[Marc-André Lureau]

Hi,

This series is based on previously discussed "[PATCH v4 00/29]
vhost-user for input & GPU" and "vhost-user: define conventions for
vhost-user backends" work. The GPU part is left off for now.

This series introduces a "vhost-user-backend": an helper object to be
used by vhost-user devices to ease with backend initialization and
handling. As a simple showcase, a "vhost-user-input-pci" device is
introduced, which can be used with the "contrib: add vhost-user-input"
example. vhost-user-input isn't meant to be installed, discovered or
used by libvirt: no installation is done (no vhost-user JSON file is
provided either).

thanks

v5:
- rebased
- removed useless "child" struct field leftover
- add Gerd r-b tags

v4:
- drop "RFC: add explicit can_migrate to vhost_user_backend_dev_init()"
- remove useless "cmd" struct field leftover

v3:
- add previously sent patch "libvhost-user: fix clang enum-conversion
  warning" to fix clang build
- "define conventions for vhost-user backends" updates after Eric review
- Drop user-creatable from vhost-user-backend
- Make vhost-user-input-pci take a chardev= (instead of vhost-user=)

v2:
- rebased (VhostUserInputPCI got most of the changes, due to split)
- added "RFC: add explicit can_migrate to
  vhost_user_backend_dev_init()" to attempt to address Michael
  concerns about migration.
