Hello, I'm hoping someone can help me increase the number of RX queues that are in use on my machine.
It's an 8 core machine that is running the latest NProbe - 6.12.130420 PF_RING ixgbe-DNA - 3.10.16-DNA OS - 2.6.38-12-generic-pae #51-Ubuntu SMP Wed Sep 28 16:11:32 UTC 2011 i686 i686 i386 GNU/Linux The ixgbe driver is loaded with the following command insmod ./ixgbe.ko MQ=1,1,1,1 RSS=8,8,8,8 >From the documentation it says that it will start the number of RX queues up >to the maximum specified above (8) or the number of cores, but it appears like >it is only starting 2. The last line in the following blurp confirms that. $:/proc/net/pf_ring/dev/dna0# cat info Name: dna0 Index: 16 Address: 00:25:90:13:8C:F2 Polling Mode: DNA Type: Ethernet Family: Intel ixgbe 82599 Max # TX Queues: 8 # Used RX Queues: 2 The following 2 commands work, starting on dna0@0 and 1 /root/nprobe/nprobe -i dna0@0 -w 1048576 -q <IP>:1111 -n <IP>:2055 --cpu-affinity 1 -t 30 -l 10 -u 1 -Q 2 -V 5 -S 10 -b 1 & /root/nprobe/nprobe -i dna0@1 -w 1048576 -q <IP>:1112 -n <IP>:2055 --cpu-affinity 2 -t 30 -l 10 -u 1 -Q 2 -V 5 -S 10 -b 1 & But using dna0@3 and above fail to start, see last 3 lines below. root@CenturyLink-nprobe1:~/nprobe# /root/nprobe/nprobe -i dna0@3 -w 1048576 -q 66.112.11.90:1112 -n 192.168.10.1:2055 -n 66.112.11.90:20555 -a --cpu-affinity 2 -t 30 -l 10 -u 1 -Q 2 -V 5 -S 10 -b 1 26/Apr/2013 12:01:21 [nprobe.c:2981] WARNING: Unable to parse sampling option: discarded 26/Apr/2013 12:01:21 [nprobe.c:3413] Welcome to nprobe v.6.12.130420 ($Revision: 3268 $) for i686-pc-linux-gnu with native PF_RING acceleration 26/Apr/2013 12:01:21 [nprobe.c:3441] Tracing enabled 26/Apr/2013 12:01:21 [util.c:2320] This computer has 8 processor(s) 26/Apr/2013 12:01:21 [util.c:2332] Adding CPU 2 to the CPU affinity set 26/Apr/2013 12:01:21 [util.c:2347] CPU affinity successfully set to 2 26/Apr/2013 12:01:21 [plugin.c:143] Loading plugins... 26/Apr/2013 12:01:21 [plugin.c:159] Loading plugins [.so] from ./plugins 26/Apr/2013 12:01:21 [plugin.c:507] Loaded './plugins/bgpPlugin.so' 26/Apr/2013 12:01:21 [plugin.c:507] Loaded './plugins/dbPlugin.so' 26/Apr/2013 12:01:21 [bgpPlugin.c:375] BGP plugin is disabled (--bgp-port has not been specified) 26/Apr/2013 12:01:21 [dbPlugin.c:161] WARNING: DB support is not enabled (disabled at compile time) 26/Apr/2013 12:01:21 [plugin.c:210] 2 plugin(s) loaded [2 delete][1 packet]. 26/Apr/2013 12:01:21 [nprobe.c:5178] Welcome to nprobe v.6.12.130420 for i686-pc-linux-gnu 26/Apr/2013 12:01:21 [nprobe.c:4494] Compiling flow templates... 26/Apr/2013 12:01:21 [plugin.c:716] Scanning plugin BGP Update Listener 26/Apr/2013 12:01:21 [plugin.c:716] Scanning plugin MySQL DB 26/Apr/2013 12:01:21 [plugin.c:828] 0 plugin(s) enabled 26/Apr/2013 12:01:21 [nprobe.c:3898] Using packet capture length 128 26/Apr/2013 12:01:21 [nprobe.c:3963] ERROR: Unable to open interface dna0@3. 26/Apr/2013 12:01:21 [nprobe.c:5270] ERROR: Unable to open interface dna0@3 (dna0@3: No such device exists (SIOCGIFHWADDR: No such device)) 26/Apr/2013 12:01:21 [nprobe.c:5272] ERROR: Try using -i none if you do not want capture from a NIC Any help is much appreciated!
