btw, include/linux/acpi.h: 120 121 #ifdef CONFIG_X86_IO_APIC 122 extern int acpi_get_override_irq(u32 gsi, int *trigger, int *polarity); 123 #else 124 #define acpi_get_override_irq(gsi, trigger, polarity) (-1) 125 #endif
this shouldn't be needed anymore, as acpi_get_override_irq is now independent of CONFIG_X86_IO_APIC (because of ioapic_get_irq having a placeholder in the !CONFIG_X86_IO_APIC case)
But on the other hand, the code flow for the !CONFIG_X86_IO_APIC would be kind of silly... what's the rationale for mp_find_ioapic returning 0 in the !CONFIG_X86_IO_APIC case? And how do I check compilation of !CONFIG_X86_IO_APIC? It looks like it already has problems, as mp_find_ioapic_pin is not stubbed out, or am I overlooking something?
Regards, Flo
