Hi Damjan, There is a comment that says "preallocate at least 16MB of hugepages per socket, if more is needed it is up to consumer to preallocate more". What does a consumer need to do in order to preallocate more?
I've recently had problems using AES-GCM with IPsec on a test system. Mempool allocation for the DPDK aesni_gcm crypto vdev fails during initialization. An error message like this is logged: vnet[4765]: crypto_create_session_drv_pool: failed to create session drv mempool I found that the DPDK memory allocation set with socket-mem is 64 MB by default and this is being exhausted by the various mempool allocations. This behavior seems to have started with change https://gerrit.fd.io/r/#/c/16287/ ("dpdk-ipsec-mempool: allocate from dpdk mem specified by socket-mem in startup.conf"). When I increase socket-mem in startup.conf to 128 MB, the configured crypto devices successfully initialize. When support for socket-mem goes away, what will need to be done to ensure that enough memory is available for crypto devices?
