I am certainly interested in ideas on how to improve the output.
That version was derived from a local patch; in our case I wanted a
simple format for the output. Essentially, the timehist output is a
'text' version of the samples, with timestamps and address conversions
where possible.
Arnaldo has started a new version of it wherein the wall clock is a new
event that can be sampled (e.g., perf top) or generated at given rate. I
spent time looking at the changes to perf command, but have been
sidetracked with other priorities.
