[ltt-dev] Fwd: Re: Lttng and Tiny Core?

[Medved, Michael]

Per Mathieu's email, I'm moving my question to this mailing list.

In response to his question - I've already built the tiny core 2.6.33.3 kernel and installed it and it seems to work just fine.  So when I drop the patch into this build is when things start going awry.  

The 2.6.33 (already patched for TC) can be had here:  

http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux/3.x/release/src/kernel/

Usually these questions go through the mailing list,
ltt-dev at lists.casi.polymtl.ca.

You should probably try booting your kernel without the lttng patches applied to
make sure it's not just a matter of a missing driver (e.g. proprietary nvidia
?) from your kernel per se.

The problem may not even be related to lttng, so it would be good to check that
first. So you should try a 2.6.33.3 kernel without lttng applied.

Mathieu

OK, can you try disabling all the lttng-specific options and rebuild ?

Also try compiling them as modules, loading one by one, see which one
fails.

Also having the console output you get when it crashes would be helpful.
A serial console usually does the trick.

Thanks,

Mathieu

[ltt-dev] Fwd: Re: Lttng and Tiny Core?

[Medved, Michael]

I tried dropping in the lttng patch but not actually activating any of 
the options in menuconfig.  That seems to work (at least on a 
virtualbox, I can try it on HW on Monday), so now I'm compiling with 
Markers and Immediate Value, but no Lttng.  We'll see if that works and 
I'll drop a reply.

[Medved, Michael]

Interestingly enough, when I just compile in Activate Markers and 
Immediate Value optimization, I get problems.  No lttng stuff.  Attached 
is the serial dump... after "Done" shows up on the console it just 
sits.  You can type, but it has no effect.
