Hi all,
Perhaps , is there something I didn't understand,
But I can't handle PCI IRQs !
For the ISA Irqs, no pb ! all my drivers work well (ISA NE2000 for
exemple).
But when I trie to handle PCI Irq, no response !
( And I couldn't try the NE2000 PCI driver I've done, but it must be
idem ... :(
I tried the Irq show at boot by the Bios ... but no response.
I tried the Irq remapped via the IO_APIC (9->17) but no response too.
I'm sure I forget something !
exemple of my handler is ( I can't do more compressed ;)
void handler(void)
{
// do something ...
rt_pend_linux_irq(dev->irq) ;
}
int init_module()
{
// find the PCI card with pci_find_device ...
rt_request_global_irq(dev->irq,handler) ;
...
}
when the irq passed in argument is the ISA irq, I don't care of
IO_APIC remapping of the IRQ and it works.
Hardware:
ASUS-P2B dual-PentiumIII 450MHz
256MB RAM
Testing device : EtherPowerII Ethernet card ( everything is done ...
just the handling of rx ring with irq do not work... same for tx
transmit_ok ).
