[linux-dvb] Re: AV7110 stable protocol proposal

[Emil Naepflein <Emil.Naepflein@philosys.de>]

Hi Ralph,

here we are. I now call the interrupt functions directly.

The first column identifies the trace point:
00: av7110_irq()
2nd column: av7110 pointer
3rd column: isr
            0x00080000 debi interrupt
            0x00000008 gpio interrupt

01: gpioirq()
2nd column: av7110 pointer
3rd column: debitype read from hardware

02: debiirq()
2nd column: av7110 pointer
3rd column: debitype in av7110->debitype

It looks like the interrupt is issued twice. 
I have also moved the clear of the irq register in saa7146_irq() behind
the call to the extensions. This improved the situation a bit.
