These are steps for using the QA API, i.e. cpaCyXXX APIs.
Also the ICP_WITHOUT_IOMMU condition is only needed if intending to access the QAT HW from the Host. If you intend to access the crypto services on QAT via the VF on a VM, then you can use the standard out of the box install for a HOST. Once the VF device is passed through to the VM, on the VM it can be passed straight through to the user-space DPDK QAT PMD without a QAT kernel driver. i.e. follow the bind commands on http://dpdk.org/doc/guides/cryptodevs/qat.html to bind the VF to either igb_uio or vfio-pci Then build your application to use the cryptodev APIs, see http://dpdk.org/doc/guides/sample_app_ug/ipsec_secgw.html for an example of how to do this. If you just want to get it up and running without a traffic generator, you can use the test app to run a sanity check against any of the crypto poll mode drivers, e.g. to run some basic functional tests against the QAT PMD, e.g. use dpdk/usertools/dpdk-setup.sh to allocate huge pages start test app, e.g. test -n1 -l1 (The test app has moved in a recent release, you should find it at either dpdk/build/app/ or dpdk/build/build/test/test ) Run the qat test suite with >cryptodev_qat_autotest > Please help here. > > Regards, > > Pankaj Joshi
