# dcce1625	21-Oct-2021	Viresh Kumar <[email protected]>	i2c: virtio: Add support for zero-length requests The virtio specification received a new mandatory feature (VIRTIO_I2C_F_ZERO_LENGTH_REQUEST) for zero length requests. Fail if the feature isn't off i2c: virtio: Add support for zero-length requests The virtio specification received a new mandatory feature (VIRTIO_I2C_F_ZERO_LENGTH_REQUEST) for zero length requests. Fail if the feature isn't offered by the device. For each read-request, set the VIRTIO_I2C_FLAGS_M_RD flag, as required by the VIRTIO_I2C_F_ZERO_LENGTH_REQUEST feature. This allows us to support zero length requests, like SMBUS Quick, where the buffer need not be sent anymore.

The controller can be emulated by the backend driver in any device model software by following the virtio protocol. The device specification can be found on https://lists.oasis-open.org/archives/virtio-comment/202101/msg00008.html. By following the specification, people may implement different backend drivers to emulate different controllers according to their needs.
