OK, this is the DPDK initialization. The original code, the dpdkd initialized info: EAL: Detected CPU lcores: 128 EAL: Detected NUMA nodes: 10 EAL: Static memory layout is selected, amount of reserved memory can be adjusted with -m or --socket-mem EAL: Detected static linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'VA' EAL: VFIO support initialized Revised code, the dpdkd initialized info: EAL: Detected CPU lcores: 128 EAL: Detected NUMA nodes: 16 EAL: Static memory layout is selected, amount of reserved memory can be adjusted with -m or --socket-mem EAL: Detected static linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'VA' EAL: VFIO support initialized > > > On 2022-08-31 10:47:24 +0200, Nole Zhang wrote: > > > > > > > > > > > > > -----Original Message----- > > > > From: Thomas Monjalon <tho...@monjalon.net> > > > > Sent: 2022年8月29日 21:15 > > > > To: Nole Zhang <peng.zh...@corigine.com>; Chaoyong He > > > > <chaoyong...@corigine.com> > > > > Subject: Re: [PATCH v1] buildtools: ensure the NUMA nodes are > > > > counted correct > > > > > > > > 29/08/2022 13:17, Nole Zhang: > > > > > From: Thomas Monjalon <tho...@monjalon.net> > > > > > > 02/08/2022 09:54, Chaoyong He: > > > > > > > From: Peng Zhang <peng.zh...@corigine.com> > > > > > > > > > > > > > > Sorting a list of strings with the format "node[0-9]+" in > > > > > > > order to find the largest integer by looking at the last > > > > > > > item after the sort breaks.
