Hi, guys
Can dpdk support allocate mempool and create ring in kernel level? I know
dpdk is user space driver, but many application need a channel to transmit
data from kernel to user space without any hardware dependency(just like pf
ring)? Anyone has a sample like this?
Best Regards
John Gong

Have you looked at the KNI kernel module and library, it might provide what you need? It is documented in the programmers guide, if you want to read up about it.

Thanks, Bruce, it's a good sample.
