CONFIG_APIC_TIMER
¶
New local APIC timer
Type: bool
Help¶
Use the x86 local APIC in one-shot mode as the system time
source. NOTE: this probably isn't what you want except on
older or idiosyncratic hardware (or environments like qemu
without complete APIC emulation). Modern hardware will work
better with CONFIG_APIC_TSC_DEADLINE_TIMER.
Defaults¶
No defaults. Implicitly defaults to n
.
