https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230465 Bug ID: 230465 Summary: ixl: not working in netmap mode Product: Base System Version: 11.2-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: halfling@halfling.com.br Hello! I have a ixl NIC (chip=0x15728086 'Ethernet Controller X710 for 10GbE SFP+) and I'm trying to work with netmap. When I was compiling kernel with ixl support I have errors with missing reference of: "'ixl_rx_miss', 'ixl_rx_miss_bufs and 'ixl_crcstrip'" so then I modify ixl_txrx.c and added this references like this: #ifdef DEV_NETMAP #include <dev/netmap/if_ixl_netmap.h> int ixl_rx_miss = 0, ixl_rx_miss_bufs = 0, ixl_crcstrip = 1; #endif /* DEV_NETMAP */ When I did this my kernel was compiled with sucess and now I see ixl interfaces in "ifconfig" command. Then now I'm trying netmap on then, but seems not working. In my application on top of netmap I see "dmesg" like this: Aug 8 14:46:56 rt1 kernel: 415.918289 [1637] nm_txsync_prologue ixl0 TX3: fail 'kring->nr_hwcur >= n || kring->rhead >= n || kring->rtail >= n || kring->nr_hwtail >= n' h 2 c 2 t 1387166207 rh 1 rc 1 rt 1387166207 hc 1 ht 1387166207 Aug 8 14:46:56 rt1 kernel: 415.973692 [1758] netmap_ring_reinit called for ixl0 TX3 Aug 8 14:46:56 rt1 kernel: 415.990602 [1783] netmap_ring_reinit total 1 errors Aug 8 14:46:56 rt1 kernel: 416.006198 [1787] netmap_ring_reinit ixl0 TX3 reinit, cur 2 -> 1 tail 1387166207 -> 1387166207 Aug 8 14:46:56 rt1 kernel: 416.032990 [1637] nm_txsync_prologue ixl0 TX3: fail 'kring->nr_hwcur >= n || kring->rhead >= n || kring->rtail >= n || kring->nr_hwtail >= n' h 2 c 2 t 1387166207 rh 1 rc 1 rt 1387166207 hc 1 ht 1387166207 Aug 8 14:46:56 rt1 kernel: 416.088614 [1758] netmap_ring_reinit called for ixl0 TX3 Aug 8 14:46:56 rt1 kernel: 416.105520 [1783] netmap_ring_reinit total 1 errors Aug 8 14:46:56 rt1 kernel: 416.121113 [1787] netmap_ring_reinit ixl0 TX3 reinit, cur 2 -> 1 tail 1387166207 -> 1387166207 Aug 8 14:46:57 rt1 kernel: 417.089185 [1637] nm_txsync_prologue ixl0 TX3: fail 'kring->nr_hwcur >= n || kring->rhead >= n || kring->rtail >= n || kring->nr_hwtail >= n' h 2 c 2 t 1387166207 rh 1 rc 1 rt 1387166207 hc 1 ht 1387166207 Aug 8 14:46:57 rt1 kernel: 417.144605 [1758] netmap_ring_reinit called for ixl0 TX3 Aug 8 14:46:57 rt1 kernel: 417.161510 [1783] netmap_ring_reinit total 1 errors Aug 8 14:46:57 rt1 kernel: 417.177110 [1787] netmap_ring_reinit ixl0 TX3 reinit, cur 2 -> 1 tail 1387166207 -> 1387166207 Aug 8 14:46:58 rt1 kernel: 418.138193 [1637] nm_txsync_prologue ixl0 TX3: fail 'kring->nr_hwcur >= n || kring->rhead >= n || kring->rtail >= n || kring->nr_hwtail >= n' h 2 c 2 t 1387166207 rh 1 rc 1 rt 1387166207 hc 1 ht 1387166207 Aug 8 14:46:58 rt1 kernel: 418.193599 [1758] netmap_ring_reinit called for ixl0 TX3 Aug 8 14:46:58 rt1 kernel: 418.210507 [1783] netmap_ring_reinit total 1 errors Aug 8 14:46:58 rt1 kernel: 418.226096 [1787] netmap_ring_reinit ixl0 TX3 reinit, cur 2 -> 1 tail 1387166207 -> 1387166207 Using pkt-get from netmap github I'm able to receive packets but not able to transmit then like this: comand: pkt-gen -i ixl0 -f tx 637.872347 main [2593] interface is ixl0 637.872394 main [2727] running on 1 cpus (have 8) 637.872601 extract_ip_range [468] range is 10.0.0.1:1234 to 10.0.0.1:1234 637.872618 extract_ip_range [468] range is 10.1.0.1:1234 to 10.1.0.1:1234 638.046374 main [2822] mapped 294020KB at 0x801600000 Sending on netmap:ixl0: 8 queues, 1 threads and 1 cpus. 10.0.0.1 -> 10.1.0.1 (00:00:00:00:00:00 -> ff:ff:ff:ff:ff:ff) 638.046466 main [2919] Sending 512 packets every 0.000000000 s 638.046507 start_threads [2274] Wait 2 secs for phy reset 640.145075 start_threads [2276] Ready... 640.145254 sender_body [1464] start, fd 3 main_fd 3 640.863306 sender_body [1538] poll error on 3 ring 0-7 641.198102 main_thread [2364] 7.780 Kpps (8.191 Kpkts 3.932 Mbps in 1052845 usec) 511.94 avg_batch 0 min_space 641.372908 main_thread [2391] ouch, thread 0 exited with error Sent 8191 packets 491460 bytes 16 events 60 bytes each in -1533750640.15 seconds.
