Dear list, I'm experiencing problems allocating big chunks of memory with rte_malloc_socket. Basically, it successfully allocates 6GB but returns NULL when I try to allocate 8GB. I tried dpdk-1.5.1 and 1.7.1 and got similar behavior. First machine I was trying this on had 29*1GB hugepages on single NUMA node, preallocated using grub. Another one had 14000*2Mb hugepages split between two sockets.
Are there any restrictions on maximum size of the block to be allocated with rte_malloc_socket? $ mount |grep hug nodev on /mnt/huge type hugetlbfs (rw,pagesize=1Gb) $ cat /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages 29 $ lsb_release -a No LSB modules are available.
