Is this something that distributions are likely to be happy enabling by default? I gather that that was not the case for latencytop, and it would really be a shame if timechart wasn't used as widely as it might be.

Yes, since it's an extension/usage of performance counters, it should be present in distributions that have perfcounters enabled.

In fact since it's a new sub-command of tools/perf/ it will get into those distributions automatically, once they update to a kernel that includes these bits.

So "perf timechart" should show up in a distro near you.

the distros I use (moblin and fedora) both have latencytop on
I'm not aware of any distro that doesn't have it on...

Debian does not ship with a latencytop-enabled kernel:

The reason appears to be that this option introduces too many debug options, which debian does not like to enable by default.
