Yes. cat /sys/devices/system/clocksource/clocksource0/available_clocksource prints the available clocksources, for example: "tsc acpi_pm jiffies". cat /sys/devices/system/clocksource/clocksource0/current_clocksource shows which source is used, and echo acpi_pm > /sys/devices/system/clocksource/clocksource0/current_clocksource makes it to use acpi_pm. Of course, ntpd must recalibrate the frequency drift then. After that the drift value seems to be correct after reboots! The time source can be selected at boot time by adding "clocksource=acpi_pm" to the kernel command line. _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
