CONFIG_APIC_TIMER_IRQ

Local APIC timer IRQ

Type: int

Help

This option specifies the IRQ used by the local APIC timer.
Note: this MUST be set to the index immediately after the
last IO-APIC IRQ (the timer is the first entry in the APIC
local vector table).  This footgun is not intended to be
user-configurable and almost certainly should be managed via
a different mechanism.

(Includes any dependencies from ifs and menus.)
