Hi. I use zynqMP and DMA in PL.
I wrote an app for xdma for transfer data from PL to PS. my app is based on polling idle bit in status register of dma.
I need to change it for use interrupt.
i know with /proc, I can send signal and event from kernel to user; but xdma driver doesnt have /proc file (or I cant find it!).
Is there a solution for sending signal without /proc? or can i make a file in driver for using send signal?
driver of xdma is in linux git path: .../drivers/dma/xilinx/xilinx_dma.c
