This patch series introduce virtio crypto poll mode driver.
Since it is limited by the 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)
- RTE_CRYPTO_CIPHER_AES_CTR (128-bit, 192-bit and 256-bit keys)
Firstly build QEMU with libgcrypt cryptography support.
QEMU can then be started using the following parameters:
qemu-system-x86_64 \
[...] \
-object cryptodev-backend-builtin,id=cryptodev0 \
-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 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

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
