Hi All,
First of all, I am using DPDK 20.11, and RHEL7.2
I have encountered the `couldnt find suitable memseg_list` error in my
program
From what I could gather I should be able to solve this issue by modifying
the following values in rte_config.h:
#define RTE_MAX_HEAPS 32
#define RTE_MAX_MEMSEG_LISTS 128
#define RTE_MAX_MEMSEG_PER_LIST 8192
#define RTE_MAX_MEM_MB_PER_LIST 32768
#define RTE_MAX_MEMSEG_PER_TYPE 32768
#define RTE_MAX_MEM_MB_PER_TYPE 65536
#define RTE_MAX_MEMZONE 2560 My questions are:
1. can I get information about memseg usage in runtime?
2. given my architecture (x86), RAM capacity (200G of 1GB hugepages), NUMA
setup (2 NUMAs), how do I calculate appropriate values?
