Ok, so period should be the interval at which an IRQ is expected. ie, if i set a buffer size for 40mS, the period should be 40, I guess.
That said, what should be a recommended value for period ? If hardware needs to generate an IRQ at the end of each period ?
It's good to allow the lowledevel driver to pass all possible period sizes to the user space. The application does decision how many wakeups expects.
