2021-09-05vdpa/mlx5: Add multiqueue supportEli Cohen3-31/+169
Multiqueue support requires additional virtio_net_q objects to be added or removed per the configured number of queue pairs. In addition the RQ tables needs to be modified to match the number of configured receive queues so the packets are dispatched to the right virtqueue according to the hash result. Note: qemu v6.0.0 is broken when the device requests more than two data queues; no net device will be created for the vdpa device. To avoid this, one should specify mq=off to qemu. In this case it will end up with a single queue. Signed-off-by: Eli Cohen <elic@nvidia.com> Link: https://lore.kernel.org/r/20210823052123.14909-7-elic@nvidia.com Signed-off-by: Michael S.

2021-09-05vdpa/mlx5: Add support for control VQ and MAC settingEli Cohen5-32/+329
Add support to handle control virtqueue configurations per virtio specification. The control virtqueue is implemented in software and no hardware offloading is involved. Control VQ configuration need task context, therefore all configurations are handled in a workqueue created for the purpose. Modifications are made to the memory registration code to allow for saving a copy of itolb to be used by the control VQ to access the vring. The max number of data virtqueus supported by the driver has been updated to 2 since multiqueue is not supported at this stage and we need to ensure consistency of VQ indices mapping to either data or control VQ.

virtio_mem_set_fake_offline() might sleep now, and we call it under rcu_read_lock(). To fix it, simply move the rcu_read_unlock() further up, as we're done with the device.

2021-08-27cryptoloop: add a deprecation warningChristoph Hellwig2-2/+4
Support for cryptoloop has been officially marked broken and deprecated in favor of dm-crypt (which supports the same broken algorithms if needed) in Linux 2.6.4 (released in March 2004), and support for it has been entirely removed from losetup in util-linux 2.23 (released in April 2013). Add a warning and a deprecation schedule. Signed-off-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/20210827163250.255325-1-hch@lst.de Signed-off-by: Jens Axboe <axboe@kernel.dk>
