Hi,
If I have an application using poll() to wait for an event, and that
event it triggered by an interrupt handling routine in the kernel. E.g.
DMA transaction completed. Is there any way for me to measure the
latency between the kernel interrupt, and my application returning from
the poll() call?
James
