OK, I'll bite. Where is the link to the program source?

it was posted to lkml a few days ago; it's unfortunately not yet just "download a bit of userspace program", it includes some kernel infrastructure patches as well.

Thank you for the info. Gosh it is nice to have LWN around. :)

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.

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...

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