virtio: allow extra context per descriptor

2017-05-02T20:41:43Z

Allow extra context per descriptor. To avoid slow down for data path, this disables use of indirect descriptors for this vq. Signed-off-by: Michael S. Tsirkin

virtio: allow drivers to validate features

2017-04-07T13:38:59Z

Some drivers can't support all features in all configurations. At the moment we blindly set FEATURES_OK and later FAILED. Support this better by adding a callback drivers can use to do some early checks. Signed-off-by: Michael S. Tsirkin

virtio_net: refactor freeze/restore logic into virtnet reset logic

2017-02-07T15:05:12Z

For XDP we will need to reset the queues to allow for buffer headroom to be configured. In order to do this we need to essentially run the freeze()/restore() code path. Unfortunately the locking requirements between the freeze/restore and reset paths are different however so we can not simply reuse the code. This patch refactors the code path and adds a reset helper routine. Signed-off-by: John Fastabend Acked-by: Jason Wang Signed-off-by: David S. Miller

virtio: Add improved queue allocation API

2016-03-02T15:01:57Z

This leaves vring_new_virtqueue alone for compatbility, but it adds two new improved APIs: vring_create_virtqueue: Creates a virtqueue backed by automatically allocated coherent memory. (Some day it this could be extended to support non-coherent memory, too, if there ends up being a platform on which it's worthwhile.) __vring_new_virtqueue: Creates a virtqueue with a manually-specified layout. This should allow mic_virtio to work much more cleanly. Signed-off-by: Andy Lutomirski Signed-off-by: Michael S. Tsirkin

virtio: drop virtio_device_is_legacy_only

virtio: drop legacy_only driver flag

virtio: add API to detect legacy devices

2014-12-09T10:06:33Z

transports need to be able to detect legacy-only devices (ATM balloon only) to use legacy path to drive them. Add a core API to do just that. The implementation just blacklists balloon: not too pretty, but let's not over-engineer. Signed-off-by: Michael S. Tsirkin Acked-by: Cornelia Huck

virtio_balloon: add legacy_only flag

2014-12-09T10:06:32Z

We have no plans to support virtio 1.0 in balloon driver. Add an explicit flag to mark it legacy only. This will be used by follow-up patches. Signed-off-by: Michael S. Tsirkin
