It seems strange that interrupts would be somehow linked to a ucontext? interrupts are highly limited, you can DOS the entire system if someone abuses this. Generally I expect a properly functioning driver to use one interrupt per CPU core. You should tie the CQ to a shared EQ belong to the core that the CQ wants to have affinity to. Jason
