All software interrupts need to be acknowledged in the interrupt service
routine. There should be documentation to this effect if you look for it. I
assume that the corresponding GPIO Interrupt Flag Register 2 should be read
within your interrupt service routine, and if you do that then you will get a
steady stream of interrupts - not just the first one.

i configure all the interrupt in DSP/BIOS, i use timer to generate a sync signal
output at gpio 11, so it works and the gpio output a sync signal which is 10 ms
1 and 990 ms 0 until i stop it. i set gpio 10 as a input pin and let it
trigerred a interrupt when it encount a rising edge. inside the interrupt
routine i let variant count increas 1 when gpio is triggered.however, the gpio
only trigger once then the gpio 11 stop to send any sync signal.
