2020-04-03Improve logic for setting trace clockSeungha Son2-8/+36
Set the clock to the best available option while tracing. Use 'boot' if it's available; otherwise, use 'mono'. If neither are available use 'global'. Any write to the trace_clock sysfs file will reset the buffer, so only update it if the requested value is not the current value. Reference : https://www.kernel.org/doc/Documentation/trace/ftrace.txt trace_clock: Whenever an event is recorded into the ring buffer, a "timestamp" is added. This stamp comes from a specified clock. By default, ftrace uses the "local" clock. This clock is very fast and strictly per cpu, but on some systems it may not be monotonic with respect to other CPUs. In other words, the local clocks may not be in sync with local clocks on other CPUs. Usual clocks for tracing: # cat trace_clock [local] global counter x86-tsc The clock with the square brackets around it is the one in effect. local: Default clock, but may not be in sync across CPUs global: This clock is in sync with all CPUs but may be a bit slower than the local clock. mono: This uses the fast monotonic clock (CLOCK_MONOTONIC) which is monotonic and is subject to NTP rate adjustments. boot: This is the boot clock (CLOCK_BOOTTIME) and is based on the fast monotonic clock, but also accounts for time spent in suspend. Since the clock access is designed for use in tracing in the suspend path, some side effects are possible if clock is accessed after the suspend time is accounted before the fast mono clock is updated. In this case, the clock update appears to happen slightly sooner than it normally would have. Also on 32-bit systems, it's possible that the 64-bit boot offset sees a partial update. These effects are rare and post processing should be able to handle them. See comments in the ktime_get_boot_fast_ns() function for more information.
