CONFIG_CLOCKSOURCE_WATCHDOG_MAX_SKEW_US: Clocksource watchdog maximum allowable skew (in microseconds)

General informations

The Linux kernel configuration item CONFIG_CLOCKSOURCE_WATCHDOG_MAX_SKEW_US has multiple definitions:

Clocksource watchdog maximum allowable skew (in microseconds) found in kernel/time/Kconfig

The configuration item CONFIG_CLOCKSOURCE_WATCHDOG_MAX_SKEW_US:

• prompt: Clocksource watchdog maximum allowable skew (in microseconds)
• type: int
• depends on: CONFIG_CLOCKSOURCE_WATCHDOG
• defined in kernel/time/Kconfig
• found in Linux kernels: 6.10–6.15, 6.16-rc+HEAD

Help text

Specify the maximum amount of allowable watchdog skew in microseconds before reporting the clocksource to be unstable. The default is based on a half-second clocksource watchdog interval and NTP's maximum frequency drift of 500 parts per million. If the clocksource is good enough for NTP, it is good enough for the clocksource watchdog!
