1.4. Pre-Installation Configuration
1.4.1. Config File Options
The following options can be modified in the config
file.
Please note that enabling debugging options may affect system performance.
CONFIG_RTE_MBUF_DEFAULT_MEMPOOL_OPS
( set toocteontx_fpavf
)Set default mempool ops to octeontx_fpavf.
CONFIG_RTE_LIBRTE_OCTEONTX_MEMPOOL
(defaulty

1.4.2. Driver Compilation
To compile the OCTEONTX FPAVF MEMPOOL PMD for Linux arm64 gcc target, run the
following make
command:
cd <DPDK-source-directory>
make config T=arm64-thunderx-linuxapp-gcc test-build
1.5. Initialization
The octeontx fpavf mempool initialization similar to other mempool drivers like ring. However user need to pass –base-virtaddr as command line input to application example test_mempool.c application.
Example:
./build/app/test -c 0xf --base-virtaddr=0x100000000000 \
--mbuf-pool-ops-name="octeontx_fpavf"
