Hello All, I want to know the smp_affinity of mine Ethernet interface so i did
[root@server1 124]# cat /sys/class/net/eth7/device/irq 29 [root@server1 124]# cat /sys/class/net/eth5/device/irq 34 then i did [root@server1 124]#cd /proc/irq [root@server1 irq]# ls 0 103 107 110 114 118 121 125 129 132 136 141 17 21 4 64 68 71 75 79 82 86 9 93 97 1 104 108 111 115 119 122 126 13 133 137 142 18 22 5 65 69 72 76 8 83 87 90 94 98 10 105 109 112 116 12 123 127 130 134 138 15 19 23 59 66 7 73 77 80 84 88 91 95 99 100 106 11 113 117 120 124 128 131 135 14 16 2 3 6 67 70 74 78 81 85 89 92 96 default_smp_affinity I didn't found the 29 and 34 here..... Then i did cat /proc/interrupts see the attached file. There are many eth7-0,eth7-1...eth7-15...what are these? Thanks
