Hello,
While looking at Seastar, I see it uses this patch on top of DPDK:
build: add meson options of max_memseg_lists
RTE_MAX_MEMSEG_LISTS = 128 is not enough for high-memory machines,
in our case, we need to increase it to 8192.
so add an option so user can override it.
https://github.com/scylladb/dpdk/commit/cafaa3cf457584de
I think we could allow to configure this at runtime,
as we did already for RTE_MAX_MEMZONE:
we've added rte_memzone_max_set() / rte_memzone_max_get().
Opinions, comments, volunteers?
