As discussed at Plumbers, here are my patches to add a TSC clock to ftrace.
Also noticeable is that the formatting patch improves the output of the
"counter" clock.
David Sharp (3):
tracing,x86: add a TSC trace_clock; reset buffer on clock change
tracing: reset ring buffer when changing trace_clocks
tracing: format non-nanosec times from tsc clock without a decimal
point.
