Hi Damjan and vPPers, I got a question about the physical mem management in vPP.
As I understand, we specify socket-mem in startup.conf for DPDK to allocate mem for itself, but we are using vPP phymem allocator for mbuf and crypto PMDs if vdev is specified. The latter consist of crypto op , session, and driver pools, and they are quite small in general. However, at least one hugepage will be allocated for each pool, which could be 1GB. Big waste in a way. DPDK instead handles it in a better way using a mem segment based mechanism. Question: why use a customzied dpdk_pool_create instea of asking DPDK to manage mempool just like rte_pktbuf_create_by_ops?

No guest userspace needed, no disk image, guest kernel just runs bash script which starts testpmd.... https://gist.github.com/dmarion/161d83165d27af7c39ab807beae4746c -- Damjan
