How to pin an interrupt thread to a specific CPU core?

[Michio Honda]

Hi,

Does anyone know how to do this? I want to ensure both my kqueue-based TCP
server app thread and the interrupt thread for the NIC to run at the same
CPU core.

Cheers,

cpuset -l $corenumber -x $irqnumber
cpuset -l 0 -x 259

This is documented in the cpuset(1) manual page.
