Interrupt from PRU to ARM

Hello Everybody,

I’ve got a problem which I can not solve through tutorials and other stuff. Therefore I am asking you all:

Has anybody an example on how to run an Interrupt from PRU to ARM by using remoteproc and the 4.14 kernel?

The problem I face is the whole Init sequence for interrupt checking on the ARM, as it is completely new to me, and I only found examples using polling, but I need a “actual” interrupt.

I’m looking forward to get answers.

Regards
Chris

AFAIK there’s no interrupt support in remoteproc at all.

Find example code at (uio_pruss driver)
