CONFIG_XUK_APIC_TSC_SHIFT¶
Power-of-two divisor between TSC and APIC timer
Type: int
Help¶
Configures the precision of the APIC timer as a bit shift of the TSC frequency. High values “slow down” the tick rate of the APIC timer and allow for longer timeouts at the expense of precision.
Defaults¶
- 6
