[PATCH v2 0/4] virtio: Refactor vhost input stub

Posted by Leo Yan 1 year ago

This series is to refactor vhost stub vhost-user-input.

Since vhost input stub requires set_config() callback for communication
event configurations between the backend and the guest, patch 01 is a
preparison for support set_config() callback in vhost-user-base.

The patch 02 is to add documentation for vhost-user-input.

The patch 03 is to move virtio input stub from the input folder to the
virtio folder.

The patch 04 derives vhost-user-input from vhost-user-base.  We reuse
the common code from vhhost-user-base as possible and the input stub is
simplized significantly.

This patch set has been tested with the backend daemon:

  # ./build/contrib/vhost-user-input/vhost-user-input \
		     -p /dev/input/event20 -s /tmp/input.sock

The series is based on "[PATCH v8 0/7] virtio: cleanup
vhost-user-generic and reduce c&p" which introduces vhost-user-base.
Based-on: <20231107180752.3458672-1-alex.bennee@linaro.org>

Changes from v1:
- Fixed typo in vhost-user-input.rst.
- Updated MAINTAINERS for new added input document and
  changing folder for vhost-user-input.c.
