4 Virtio Crypto Poll Mode Driver
5 ==============================
7 The virtio crypto PMD provides poll mode driver support for the virtio crypto
13 The virtio crypto PMD has support for:
17 * ``RTE_CRYPTO_CIPHER_AES_CBC``
21 * ``RTE_CRYPTO_AUTH_SHA1_HMAC``
26 * Only supports the session-oriented API implementation (session-less APIs are
28 * Only supports modern mode since virtio crypto conforms to virtio-1.0.
29 * Only has two types of queues: data queue and control queue. These two queues
30 only support indirect buffers to communication with the virtio backend.
31 * Only supports AES_CBC cipher only algorithm and AES_CBC with HMAC_SHA1
32 chaining algorithm since the vhost crypto backend only these algorithms
34 * Does not support Link State interrupt.
35 * Does not support runtime configuration.
37 Virtio crypto PMD Rx/Tx Callbacks
38 ---------------------------------
42 * ``virtio_crypto_pkt_rx_burst``
46 * ``virtio_crypto_pkt_tx_burst``
51 Quick instructions are as follows:
53 Firstly run DPDK vhost crypto sample as a server side and build QEMU with
55 QEMU can then be started using the following parameters:
57 .. code-block:: console
61 -chardev socket,id=charcrypto0,path=/path/to/your/socket \
62 -object cryptodev-vhost-user,id=cryptodev0,chardev=charcrypto0 \
63 -device virtio-crypto-pci,id=crypto0,cryptodev=cryptodev0
66 Secondly bind the uio_pci_generic driver for the virtio-crypto device.
67 For example, 0000:00:04.0 is the domain, bus, device and function
68 number of the virtio-crypto device:
70 .. code-block:: console
72 modprobe uio_pci_generic
73 echo -n 0000:00:04.0 > /sys/bus/pci/drivers/virtio-pci/unbind
74 echo "1af4 1054" > /sys/bus/pci/drivers/uio_pci_generic/new_id
76 Finally the front-end virtio crypto PMD driver can be installed.
81 The unit test cases can be tested as below:
83 .. code-block:: console
85 reserve enough huge pages
87 meson test cryptodev_virtio_autotest
89 The performance can be tested as below:
91 .. code-block:: console
93 reserve enough huge pages
96 ./app/dpdk-test-crypto-perf -l 0,1 -- --devtype crypto_virtio \
97 --ptest throughput --optype cipher-then-auth --cipher-algo aes-cbc \
