v3: - set cpu affinity when data queues are not equal to the number of online cpus. [Michael] - add TODO comments for cpu hotplug (changing the relationship of binding virtqueue and cpu) - use __u32/64 in the config space since the virtio->get() doesn't support byte-swap yet. [Michael] - drop the whole patch 1 of v2 because the above reason. - add VERSION_1 check at the beginning of

v6: - add patch 1/2 to make sparc architecture happy. [Sam] - close created sessions previousely when rekeying. - convert the priority of virtio crypto algs from 4001 to 501 which is enough. v5: - add comments for algs_lock and table_lock. [Stefan] - use kzfree instead of kfree for key material security. [Stefan] - drop unnecessary spin_lock for struct virtio_crypto_ablkcipher_ctx. -

The virtio crypto device is a virtual cryptography device as well as a kind of virtual hardware accelerator for virtual machines. The encryption anddecryption requests are placed in the data queue and are ultimately handled by thebackend crypto accelerators. The second queue is the control queue used to create or destroy sessions for symmetric algorithms and will control some advanced features in
