Hi David / Thomas.
I'm trying to understand how we deal with floppy irq on sparc64.
In arch/sparc/include/asm/floppy_64.h we have:
error = request_irq(FLOPPY_IRQ, sparc_floppy_irq,
IRQF_DISABLED, "floppy", NULL);
FLOPPY_IRQ is set equal op->archdata.irqs[0] in sun_floppy_init().
So FLOPPY_IRQ is the platform irq - and not a virtual irq.
But as I understand request_irq(...) takes a virtual irq as parameter.
But I see no-where in the code where we allocate the virtual irq
that is equal to op->archdata.irqs[0].
I am looking into this because on sparc32 I need to come
up with something to deal with the floppy interrupt.
I was about to write something that allocated a virtual irq for
the floppy irq - but wanted to check how other archs deal with the same.
And now I am confused as I do not see how it is done...
Can you help sched some light on this?
If there is some other arch I could look at to be inspired then please
let me know.
PS. sun4m boots with my latest genirq patchset :-)
But build fails if I eable FDC which I am looking at now.
