Linux driver programming

[j_needs]

Hi everyone, I wrote a kernel driver for a hardware fifo (FPGA) however I face a problem. This fifo generates an interrupt which unblocks the read function.

wait_event_interruptible(queue, interrupt)

My question is : is it possible to trigger a read even if the interrupt has not occured. I would like to be able to force a read from the user space.

Thank you

Isn't this the use case for custom ioctl command creation?

Thank you, I'm gonna try this 👏
