Dear Team, We are using 6Wind fastpath(fp-rte) which is using DPDK version 18.11.1. We are seeing 65.5G(preallocated during startup) of virtual memory for fp-rte on a 32GB machine, 10G of that was huge pages (5000 mappings of 2M.)
We found 4 strange anon (4K size) segments totaling 54.5G (16+16+16+6.5). Note: we changed / customized memory CONFIG_RTE_MAX_MEMSEG_PER_LIST=24576 and default value of CONFIG_RTE_MAX_MEMSEG_LISTS=64 used. Kindly let us know 1. Why are allocating 54.5 GB anonymous mapping 2. When will we use it ? Appreciate your quick response. Regards, Shanmugasundaram M
