The latency of ef_eventq_poll() is large

[Roser-ZY]

The latency periodically reaches to 2000ns ~ 3000ns, and when there is no event the latency is less than 100ns. I put it into a dead loop to poll and I have no idea if I accomplish the function in a wrong way?

Thanks for help.

I have improve my codes and the latency is stable in most cases, but about 60s(sometimes less than 20s) there is a large latency in ef_vi_eventq_poll. Is the ef_vi has some mechanism?
