Hi,

We have 2 NUMAs in our system, and we try to allocate a single DPDK memory pool on each NUMA.
However, we see no difference when enabling/disabling "CONFIG_RTE_EAL_NUMA_AWARE_HUGEPAGES" configuration.
We expected that disabling it will allocate pools only on one NUMA (probably NUMA0), but it actually allocates pools on both NUMAs, according to "socket_id" parameter passed to "rte_mempool_create" API.
We have 192GB memory, so NUMA1 memory starts from address: 0x1800000000.
As you can see below, "undDpdkPoolNameSocket_1" was indeed allocated on NUMA1, as we wanted, although "CONFIG_RTE_EAL_NUMA_AWARE_HUGEPAGES" is disabled:

CONFIG_RTE_LIBRTE_VHOST_NUMA=n
CONFIG_RTE_EAL_NUMA_AWARE_HUGEPAGES=n

created poolName=undDpdkPoolNameSocket_0, nbufs=887808, bufferSize=2432, total=2059MB
(memZone: name=MP_undDpdkPoolNameSocket_0, socket_id=0, vaddr=0x1f2c0427d00-0x1f2c05abe00, paddr=0x178e627d00-0x178e7abe00, len=1589504, hugepage_sz=2MB)
created poolName=undDpdkPoolNameSocket_1, nbufs=887808, bufferSize=2432, total=2059MB
(memZone: name=MP_undDpdkPoolNameSocket_1, socket_id=1, vaddr=0x1f57fa7be40-0x1f57fbfff40, paddr=0x2f8247be40-0x2f825fff40, len=1589504, hugepage_sz=2MB)

Does anyone know what is "CONFIG_RTE_EAL_NUMA_AWARE_HUGEPAGES" configuration used for?

Thanks,
Asaf
