Hello.
Thanks a lot in advance for your help and nice support.
We use tap PMD to send exception packet to kernel by DPDK primary block.
If the secondary block is driven in this state, vdev probe is
performed inside rte_eal_init
func
and memory is allocated using the rte_zmalloc_socket function if it is
a secondary block in the rte_pmd_tap_probe
(dpdk-20.11/drivers/net/tap/rte_eth_tap.c) function.
The secondary block mentioned is used to debug the primary
block and is terminated immediately after executing the command so
the memory allocated above is not free and is lost.
The secondary block does not access the tap interface,
is there any way to prevent memory allocation for tap vdev?
I am inquiring this because rte_eth_tap.c file copyrighted
