[PATCH v3 0/7] crypto: add virtio poll mode driver

[Jay Zhou <jianjay.zhou@huawei.com>]

This patch series introduce virtio crypto poll mode driver.

Since it is limited by the vhost crypto backend of the virtio-crypto,
this patch series only supports a limited subset of crypto services.
Only the following algorithms are tested:

Cipher algorithms:
  - RTE_CRYPTO_CIPHER_AES_CBC (128-bit, 192-bit and 256-bit keys)

Cipher then hash algorithms:
  - RTE_CRYPTO_CIPHER_AES_CBC with RTE_CRYPTO_AUTH_SHA1_HMAC

The qemu side has supported vhost crypto and the vhost user crypto server
side patches had been sent to DPDK community, pls see

[PATCH v2 00/10] lib/librte_vhost: introduce new vhost	user crypto backend
support
https://dpdk.org/ml/archives/dev/2018-February/091594.html

Firstly run DPDK vhost crypto sample as a server side and build QEMU with
vhost crypto enabled. 
QEMU can then be started using the following parameters:

qemu-system-x86_64 \
    [...] \
        -chardev socket,id=charcrypto0,path=/path/to/your/socket \
        -object cryptodev-vhost-user,id=cryptodev0,chardev=charcrypto0 \
        -device virtio-crypto-pci,id=crypto0,cryptodev=cryptodev0
    [...]

Bind the uio_generic driver for the virtio-crypto device.
For example, 0000:00:04.0 is the domain, bus, device and function
number of the virtio-crypto device:
    modprobe uio_pci_generic
    echo -n 0000:00:04.0 > /sys/bus/pci/drivers/virtio-pci/unbind
    echo "1af4 1054" > /sys/bus/pci/drivers/uio_pci_generic/new_id

The front-end virtio crypto PMD driver can be installed:
    cd to the top-level DPDK directory
    sed -i 's,\(CONFIG_RTE_LIBRTE_PMD_VIRTIO_CRYPTO\)=n,\1=y,' config/common_base
    make config T=x86_64-native-linuxapp-gcc
    make install T=x86_64-native-linuxapp-gcc

The unit test cases can be compiled as below:
    cd to the top-level DPDK directory
    export RTE_TARGET=x86_64-native-linuxapp-gcc
    export RTE_SDK=`pwd`
    cd to test/test
    make
    ./test (MUST reserve enough huge pages memory)
    type the command "cryptodev_virtio_autotest" to test

The result should be like this:
RTE>>cryptodev_virtio_autotest

The performance can be tested as below:

    reserve enough huge pages
    cd to the top-level DPDK directory
    export RTE_TARGET=x86_64-native-linuxapp-gcc
    export RTE_SDK=`pwd`
    cd to app/test-crypto-perf
    type the command "make" to compile
    run the tests with the following command:

    ./dpdk-test-crypto-perf -l 0,1 -- --devtype crypto_virtio \
        --ptest throughput --optype cipher-then-auth --cipher-algo aes-cbc \
        --cipher-op encrypt --cipher-key-sz 16 --auth-algo sha1-hmac \
        --auth-op generate --auth-key-sz 64 --digest-sz 12 \
        --total-ops 100000000 --burst-sz 64 --buffer-sz 2048

Please help to review, thanks!

Changes in v3:
 - set up capabilities for virtio crypto PMD [Fan]
 - delete AES-CTR unit test cases since vhost_user crypto backend does not
   support [Fan]
 - fix a variable uninitialized in virtio_crypto_queue_setup() [Xin, Fan]
 - fix a bug in virtqueue_dequeue_burst_rx()

Changes in v2:
 - using pre-allocated mempool instead of rte_malloc to improve performance [Fan]
 - split the patch into a patchset [Fan]
 - using linux/virtio_crypto.h instead of creating a copy of the file [Fan]
 - update doc/guides/cryptodevs for describing virtio crypto PMD [Fan]
 - update copyright
 - delete virtio legacy mode code since virtio-crypto conforms to virtio-1.0
 - refine the function and variable names
 - fix errors and warnings reported by checkpatch
