The OCTEON TX2 crypto poll mode driver provides support for offloading cryptographic operations to cryptographic accelerator units on the OCTEON TX2 ® family of processors (CN9XXX).
More information about OCTEON TX2 SoCs may be obtained from https://www.marvell.com
The OCTEON TX2 crypto PMD has support for:
Cipher algorithms:
Hash algorithms:
AEAD algorithms:
The OCTEON TX2 crypto PMD may be compiled natively on an OCTEON TX2 platform or cross-compiled on an x86 platform.
Enable OCTEON TX2 crypto PMD in your config file:
Refer to Marvell OCTEON TX2 Platform Guide for instructions to build your DPDK application.
Note
The OCTEON TX2 crypto PMD uses services from the kernel mode OCTEON TX2 crypto PF driver in linux. This driver is included in the OCTEON TX SDK.
List the CPT PF devices available on your OCTEON TX2 platform:
lspci -d:a0fd
a0fd is the CPT PF device id. You should see output similar to:
0002:10:00.0 Class 1080: Device 177d:a0fd
Set sriov_numvfs on the CPT PF device, to create a VF:
echo 1 > /sys/bus/pci/drivers/octeontx2-cpt/0002:10:00.0/sriov_numvfs
Bind the CPT VF device to the vfio_pci driver:
echo '177d a0fe' > /sys/bus/pci/drivers/vfio-pci/new_id
echo 0002:10:00.1 > /sys/bus/pci/devices/0002:10:00.1/driver/unbind
echo 0002:10:00.1 > /sys/bus/pci/drivers/vfio-pci/bind
Another way to bind the VF would be to use the dpdk-devbind.py script:
cd <dpdk directory>
./usertools/dpdk-devbind.py -u 0002:10:00.1
./usertools/dpdk-devbind.py -b vfio-pci 0002:10.00.1
Note
Ensure that sufficient huge pages are available for your application:
echo 8 > /sys/kernel/mm/hugepages/hugepages-524288kB/nr_hugepages
Refer to Use of Hugepages in the Linux Environment for more details.
