Hello.
void smp_boot_cpus(unsigned int max_cpus)
{
if (!max_cpus) {
smpboot_clear_io_apic_irqs();
// sets io_apic_irqs = 0;
return;
}
setup_IO_APIC();
}
void pcibios_fixup_irqs(void)
{
while (dev = pci_find_device())
if (io_apic_assign_pci_irqs)
dev->irq = IO_APIC_get_PCI_irq_vector();
}
It seems to me that this dev->irq assignment is wrong in case
when setup_IO_APIC() was not called, and this is the case for
'nosmp' parameter.
With this change:
- if (io_apic_assign_pci_irqs)
+ if (io_apic_assign_pci_irqs && io_apic_irqs)
my netwok card works with nosmp, but i never looked in
arch/i386/pci/ before, so i am probably wrong.
Or nosmp does not make sense without noapic?
Oleg.
