HI !
I'm porting the kernel and writing a bios for a custom design we are
doing, based on a SA110/285. I'm currently having some trouble with
handling of the 82C59A interrupt controller in the winbond. (The kernel
hangs as soon as it detects the chip, overflowed with interrupts from the
isa controller, it works fine but without IDE if i set isa_irq to -1).
Is the initialisation done in the kernel when isa_irq is not -1 somewhat
specific to a given hardware (Netwinder ?) like setting up level/edge
things ? Am I expected to initialize this beast from my bios ?
I'm just discovering this controller and... humm... no comment.
Is there any piece of well written explanation on how to setup this thing
? I've seen various docs but most of them suppose you already have some
knowledge about how the x86 interrupt mecanism works apparently.
Thanks for any tips...
