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

following make
command:
cd <DPDK-source-directory>
make config T=arm64-thunderx-linux-gcc
1.5. Initialization¶
The OCTEON TX 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"
