I have a USB driver that is currently receiving data on a USB interrupt endpoint. A lot of time will be required to process data received. Is there a way that I can differ or schedule a “tasklet” to be executed outside of “interrupt context” to do this processing? I want to avoid having to spend too much time in my interrupt handler.
Thanks,
dd
Schedule a work item (WDFWORKITEM), or if it takes a really long time or essentially endless processing, create your own thread (no KMDF abstraction, see PsCreateThread) and defer the work
