12 bool "Tickless System (Dynamic Ticks)"
13 depends on !ARCH_USES_GETTIMEOFFSET && GENERIC_CLOCKEVENTS
16 This option enables a tickless system: timer interrupts will
17 only trigger on an as-needed basis both when the system is
18 busy and when the system is idle.
20 config HIGH_RES_TIMERS
21 bool "High Resolution Timer Support"
22 depends on !ARCH_USES_GETTIMEOFFSET && GENERIC_CLOCKEVENTS
25 This option enables high resolution timer support. If your
26 hardware is not capable then this option only increases
27 the size of the kernel image.
29 config GENERIC_CLOCKEVENTS_BUILD
32 depends on GENERIC_CLOCKEVENTS
