<div class="bz_comment_block">
<pre class="bz_comment_text">1. in rte_pmd_af_xdp_probe() function, can't assign device.numa_node with
current socket id. Since the CPU core socket to start app can be different to
virtual xdp/device socket to attach.
===========code in rte_eth_af_xdp.c===========================
if (dev->device.numa_node == SOCKET_ID_ANY)
dev->device.numa_node = rte_socket_id();
===========code in rte_eth_af_xdp.c===========================
Same issue for rte_pmd_af_xdp_remove() and eth_dev_close().
2. For xdp_umem_configure() in xsk_configure(), also can't allocate umem at CPU
core socket which get from during eth_rx_queue_setup() phase. Because it will
probably be different to socket which "umem" wants to attach port device
belongs to.
===========code in rte_eth_af_xdp.c===========================
umem = rte_zmalloc_socket("umem", sizeof(*umem), 0, rte_socket_id());
if (umem == NULL) {
AF_XDP_LOG(ERR, "Failed to allocate umem info\n");
return NULL;
}
snprintf(ring_name, sizeof(ring_name), "af_xdp_ring_%s_%u",
internals->if_name, rxq->xsk_queue_idx);
umem->buf_ring = rte_ring_create(ring_name,
ETH_AF_XDP_NUM_BUFFERS,
rte_socket_id(),
0x0);
===========code in rte_eth_af_xdp.c===========================
