APIC support on uniprocs

h/w · 09-01-2003, 04:46 PM

hello.
im tryin to upgrade my kernel to 2.4.22, and theres an option which gets highlighted when i unselect SMP support; called "LOCAL APIC support on uniprocessors", and a following option called "IO_APIC supp for uni procs"

how do i know if this support is builtin or not?

do i need to select these 2 options if i dont opt for SMP support?

thnx.

Here's what i have in my config that I compiled last night:

Code:

[02:13 AM Tue Sep 02: stephen @ ~]
>$ grep APIC /usr/src/config-2.4.22.030901
CONFIG_X86_GOOD_APIC=y
# CONFIG_X86_UP_APIC is not set

It works fine with these settings note: if you want your machine to power down when you shut it off make sure that the ACPI is not selected. The ACPI was overiding the APM used in the shutdown.

Code:

[02:14 AM Tue Sep 02: stephen @ ~]
>$ grep ACPI /usr/src/config-2.4.22.030901
CONFIG_HOTPLUG_PCI_ACPI=m
# ACPI Support
# CONFIG_ACPI is not set

It's a different thing from APIC it is APCI it is power management for laptops I believe and it was that over-riding the APM.
