[PATCH 0/3] tracing: Introduce trace clock tai

[Kurt Kanzenbach <kurt@linutronix.de>]

Hi,

the Linux kernel tracing infrastructure has support for using different clocks
to generate timestamps for trace events. Especially in TSN networks it's useful
to have TAI as trace clock, because the application scheduling is done in
accordance to the network time, which is based on TAI. With a tai trace_clock in
place, it becomes very convenient to correlate network activity with Linux
kernel application traces.

However, there's no fast accessor for CLOCK_TAI yet. Therefore, patch #1 is
adding one. Patch #2 introduces the clock and the last one adds documentation
for it.

Thanks,
Kurt
