Hi everyone, I'm working with DPDK and could use some advice about memory management of the DPDK heap.
I need to prevent DPDK from freeing the rte_mbuf buffers once the corresponding packets have been sent with rte_eth_tx_burst(). My application has local readers as well, and so I want to keep that data around for them to read via shared memory. I would prefer to rely on explicit calls to free any of these buffers. I can find plenty of sources about rte_eth_tx_burst() freeing messages once they are sent, but cannot find a way to override this behavior, or any mention of an alternate call to send without freeing. This would let me avoid copying the data into a separate buffer just for local readers and to let them read from the same buffers that DPDK already requires., leading to a significant performance gain (less memcpy). This seems like something that should be possible *without* modifying DPDK, but I haven't figured out how yet. I know that I would need to take care that the buffers are not freed prior to sending. Thanks for any advice, -Alan
