Not receiving interrupts from FPGA to HPS
I have upgraded kernel from linux-socfpga 3.10.31 to 4.14.73 and I am having some troubles with getting the interrupts from the FPGA.
I can see, when I do "cat /proc/interrupts" my kernel modules are not getting the interrupts from GIC as they used to from the older kernel but is now receiving from gpio-dwapb.
In case of 3.10.31, IRQ number is set to expeced value and refer to the following please.
#cat /proc/interrupts
…
72 ... GIC-0 84 Level my_uio_driver
In case of 4.14.73 I got
…
r72 ... gpio-dwapb 25 Edge my_uio_drive
I would be grateful if someone have already look something similar and could tell me where the mistake is.
Thanks a lot in advance,
Simone

Hi Simone,
Please refer to the below link for FPGA interrupts using a newer version of the kernel.
