Hello, I'm an telecommunication student who is investigating about how make faster new NICs.

Do you know anything about the Linux NAPI system, Interrupt Livelock, Polling, ...?

Hello again.

My project is about new gigabit ethernet cards
Those NICs suffer interrupt livelock because they make lot of interrupts.
This is caused becaused when only 1 packet arrives it to the NIC makes an interrupt and at high rates they managed lot of interrupts.
There are some strategies like interrupt mitigation and polling,some of them are implemented on Linux NAPI subsystem.
Does anybody know something about it??

Thank you

Hello
Has anybody information about NAPI Subsystem works in Linux kernel??

I'm looking for it, but i don't find anymore than what it says on the HOW_TO's
