I know how to force the kernel to use a specific clocksource for driving the scheduler and verify that this clocksource is used. However, I don't know how to found out what clocksource Linux has assigned for other activities apart from the one mentioned (e.g. for timekeeping) and how to change it, if possible. For example, I want to find out which clocksource getnstimeofday() is using. It could be also useful if there is a way to see all the registered clocksources in the system. Thanks in advance. P.S. please cc me. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
