Just for clarification, in this case the DPDK application will work but will only use RTE_MAX_LCORE cores, right? You need to compile to use all available cores. Are cores more than RTE_MAX_LCORE usable after this patch? > > The --lcores does not need to care about the underlying cores, remove > this limitation. > +1 to remove limit in --lcores, but I didn't make it work with this patchset, I may be missing something, I tried by setting the "RTE_MAX_LCORE=32", in this case should '--lcores "(30-40)@(10-20)"' work?
