On x86 platforms, max lcores are limited to 128 by default.
On AMD EPYC processors, this limit was adjusted for native
builds in the previous patch.
https://patches.dpdk.org/project/dpdk/patch/
20230925151027.558546-1-sivaprasad.tumm...@amd.com/
As agreed earlier in mailing list, this patch adjusts the limit
for specific AMD EPYC target/cross builds.
