It is common on every modern even uniprocessor system to have apic support compiled in, so i propose to add: IUSE="apic" inherits flag-o-matic and use apic && append-flags -DHI_INTS to src_compile I haven't alpha system, and can't test on it, but in README had said that it is usefull flag on it too.
I have apic enabled on my system but would get no benefict from -DHI_INTS, as that flag enables wmsysmon to monitor more interrupts, present in alpha and true smp boxes. On my machine it would just needlessly clutter wmsysmon interface... So I think that this ebuild could benefict from 'alpha' use flag, and a local 'smp' one...
Do you enable ACPI? Besides, i have some settings about APIC support in BIOS setup. dmesg ... ACPI: Using IOAPIC for interrupt routing number of IO-APIC #2 registers: 24...
Ah, my processor does not support IO-APIC, that's where the extra INTs come from... thus we should honour alpha USE flag, and create a local hi_ints one...
New revision with added requested features is now in Portage...
