Hi,
Stay tuned as I intend to put on the web an expanded document,
including documentations about kernel internals (besides networking).
Regards,

Thanks a lot for this document Rami! I'm starting to study the kernel and it
will greatly help me to figure out how to dig into the source code. Looking
forward for the expanded version as well!
Best regards,
Paulo

Thank you so much for sharing this.
Hi All,
I was reading some stuff on interrupts and irq lines today and I thought I'll
expermient with the network rx path. To start with, I've a Virtual Machine
running 3.8 linux kernel. My machine has 4 CPU cores, network (eth) interface
is driven by pcnet_32 AMD driver and is tied to IRQ line

Hi, Kumar,
1) Regarding rx queues: what does
ls /sys/class/net/eth0/queues
show ?
2) can you try setting affinity for working only with CPU3
and see what happens after some traffic is sent by
cat /proc/interrupts?

I don't know for sure what linux does, but the NICs I've seen with
multiple queues tend to select queues by hashing incoming packets
based on source IP, sourse port, destination IP, destination port and
(if TCP) protocol.

2) Does the irqbalance service, which is common in some distros, is
running ?
