pin a subsystem to a CPU

[Bin Ren]

Hi,

I'm thinking about whether it's possible and how to pin
a subsystem of kernel, from a particular driver (such as
software RAID) to TCP network stack, to a particular
CPU. In other words, I have dual processors and how
can I make one of the CPU JUST runs TCP stack so
as to increase network throughput?

Shall I turn the piece of codes into a kernel thread? Then
how hard is it?

Thanks a lot!
