Auke,
2 Questions:
- i have an system that boots very slow, how i can change the
loggingtime from bootchart (eg. from 20sec to 40sec)?
- i have no output in the IO utilization Lines, is this normal or must i
enable anything in the kernel config?
thank you for the great and simple program!
Stephan

Thank you Auke, now it works :-)
is it possible to add code to inform user that CONFIG_SCHED_DEBUG is not
enabled if /proc/x/sched is not found? also that CONFIG_SCHEDSTATS is
not enabled if /proc/schedstat is not found?
it'll be in the README. In general, I don't want to add too much
debugging code to the program in order to keep it minimal in size etc.
btw. is there an git repo and an downloadlocation for bootchart (i dont
have found any, i have extracted the source from the srpm?
I'm working on getting it up on git.moblin.org.
thank you
Stephan

Hi Auke,
because this is an embedded system i can only give yo the follow
informations:
Starting program: /sbin/bootchartd
warning: Unable to find libthread_db matching inferior's thread
library,
thread debugging will not be available.

ok, I see now, it's failing to open /proc/<N>/sched
looks like you do miss a kernel config option to enable these files to
appear.
try enabling CONFIG_SCHED_DEBUG and let me know if that fixes, and
I'll adjust the README to reflect that requirement.
