Interrupt handling problem using linux with DE1_SoC cyclone V

Hi We are using cyclon V on DE1_SoC board to write a interrupt handling module. We used the demo from Cornell's web site (http://people.ece.cornell.edu/land/courses/ece5760/de1_soc/hps_perip...

Hello,

I'm having the same issue with 4.14 kernel.

I'm using an IP block on FPGA registered on interrupt n°73 and a Userspace driver as interface.

If I type "cat /proc/interrupts" it returns

.. ... ... ..... .... .....

73: xxx 0 gpio-dwapb 3 Edge "my_uio_driver "

.. ... ... ..... .... .....

with xxx different from 0, but blocked.

I also try to make an IP which rise an interrupt (on 73) periodically but the number of interrupt is still blocked to initial value different from 0.

Have you find a solution?

Thanks in advance,

Simone
