yes I know about this option. I tried with "profile=2" but readprofile
gave me only very little information. Will try again with "profile=4".
I suspect you won't get a greatly different result with profile=4.
The 100Hz clock doesn't give you fantastic granularity, and ofcourse
you have to be busy in the kernel to get reasonable percentages for
functions.
A few years back I coded an extra timer setup for some ColdFire
parts that gave even better resolution, look for the config option
CONFIG_HIGHPROFILE. Not sure if it works (or even compiles :-) in
the 2.6.19-uc1 version though.
I saw this option but it doesn't compile in 2.6.19-uc1. If I remember
correctly there was a patch in december which fixed this problem.[1] I
guess it should be already mainline.
Yes, should be.
BTW...any schedule for a next stable uClinux-dist with a recent kernel?
I am pretty happy with the current test release, so I suspect it will
be in the next 2 or 3 weeks.
There is 2 outstanding issues that I would like to see resolved, but
realistically they probably won't get fixed.
1. Samba doesn't build for non-MMU targets. (It is a primarily a
libc link problem).
2. iproute2 doesn't compile/link for non-MMU targets (the newer version
relies on ldopen and friends).
Regards
Greg
