LTTng 0.89 for Linux 2.6.29-rc3

LTTng 0.89 for Linux 2.6.29-rc3

[Mathieu Desnoyers]

Hi,

I just ported LTTng to the 2.6.29-rc3 kernel. It includes the following
changes :

- Tree RCU instrumentation
- Updated ext4 and jbd2 instrumentation

Please feel free to try it and report any success/problem you may have.
Note that cross-build has been slightly less tested this time because
I'll have to upgrade many of my compilers to a version compatible with
kernel 2.6.29-rc.

It also includes the recently added kprobes support through a simple

echo symbol_name > /mnt/debugfs/ltt/kprobes/enable

It's available at the new LTTng website :

http://www.lttng.org/

Thanks,

Mathieu

Hello, Matheiu,

When I try to apply this to v2.6.29-rc3, I get the following:

	can't find file to patch at input line 61
	Perhaps you used the wrong -p or --strip option?
	The text leading up to this was:

Hi Paul,

I must admit I'm a bit puzzled. I've tried to quilt push -a both 
LTTng 0.89 and LTTng 0.92 taken from the website and they both apply
correctly on 2.6.29-rc3. When I quilt pop -a, neither of those 3 files
(include/linux/ltt-core.h, ltt/ltt-core.c, ltt/ltt-relay.c) are stucked
in my tree.

I've used files from :

http://www.lttng.org/files/lttng/patch-2.6.29-rc3-lttng-0.92.tar.bz2

Which tarballs are you using exactly ?

I guess you need to apply them to your existing tree, so pointing you to
git.kernel.org lttng tree won't help much here.

Mathieu

That is indeed the one that I am using.

I am attempting to apply to v2.6.29-rc3, which is commit
18e352e4a73465349711a9324767e1b2453383e2 in the linux-2.6 git tree.

Later on, I might well want to apply on top of some other stuff, but
figured I should try it straight first.  ;-)

Are you using quilt to apply the patchset series file in the right order ?

Ummm...  No.  I never have used quilt.

Ah, there is a series file.  I guess it would not be too hard to make
an appropriate "sh" command:

cat /tmp/patch-2.6.29-rc3-lttng-0.92/series | grep -v '^#' | sed -e 's/^/patch
-p1 < \/tmp\/patch-2.6.29-rc3-lttng-0.92\//' | sh

But this complains about directories.  OK, "sudo apt-get install quilt"
followed by "man quilt".  Than "quilt import" seems to do some of the
work, but doesn't seem to apply all the patches.  Thank goodness for
"git reset --hard"!!!

Help?

Is the appropriate incantation as follows?

	cd <top of git tree>
	mkdir patches
	cp /tmp/patch-2.6.29-rc3-lttng-0.92/* patches
	quilt push -a

Yes, exactly.

And from there you can follow the LTTng manual here :

Whew!  ;-)

I get some fuzz and the following:

	patching file kernel/trace/trace-clock-32-to-64.c
	Patch attempted to create file kernel/trace/trace-clock-32-to-64.c,
	which already exists.
	Hunk #1 FAILED at 1.
	1 out of 1 hunk FAILED -- rejects in file
	kernel/trace/trace-clock-32-to-64.c

Should I be starting from somewhere other than v2.6.29-rc3?

Let's see it step by step, that should get us there.

With patches :

mkdir ~/lttng
cd ~/lttng
wget http://www.kernel.org/pub/linux/kernel/v2.6/testing/linux-2.6.29-rc3.tar.bz2
wget http://lttng.org/files/lttng/patch-2.6.29-rc3-lttng-0.92.tar.bz2
bzip2 -cd linux-2.6.29-rc3.tar.bz2 |tar xvof -
bzip2 -cd patch-2.6.29-rc3-lttng-0.92.tar.bz2  |tar xvof -
cd linux-2.6.29-rc3
mkdir patches
ln -s ../patch-2.6.29-rc3-lttng-0.92 patches
quilt push -a

Does this work ?

Leaving out the "mkdir", yes.  My apologies -- I was forgetting that
"git reset --hard" doesn't get rid of untracked files.  I do see fuzz
in a few places, but hopefully this is non-fatal.  And in any case, I
can now make the patch required to actually try this out.  ;-)

Fails to build on Power, so trying x86...  (Stock 2.6.29-rc3 does
build and boot, FWIW.)

Looks like misplaced file.

Fails to build on Power, so trying x86...  (Stock 2.6.29-rc3 does
build and boot, FWIW.)

Looks like misplaced file.

Hrm, does the file

arch/powerpc/include/asm/immediate.h exist in your tree ?

Here, with the setup done following the commands I gave you (minus the
mkdir patch), I get :


compudj@ok:~$ head testpaulmck/linux-2.6.29-rc3/arch/powerpc/include/asm/immediate.h 
#ifndef _ASM_POWERPC_IMMEDIATE_H
#define _ASM_POWERPC_IMMEDIATE_H

/*
 * Immediate values. PowerPC architecture optimizations.
 *
 * (C) Copyright 2006 Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>

 * This file is released under the GPLv2.

....

Which defines struct __imv. So hrm, normally the header should be there.
(/me still confused) :)

One thing that helps on 32-bit x86 is removing the "select HAVE_IMMEDIATE"
that you added to arch/x86/Kconfig.  I then get assembly errors:

	  AS      arch/x86/kernel/entry_32.o
	arch/x86/kernel/entry_32.S: Assembler messages:
	arch/x86/kernel/entry_32.S:272: Error: invalid character '_' in
	mnemonic
	make[1]: *** [arch/x86/kernel/entry_32.o] Error 1
	make: *** [arch/x86/kernel] Error 2

This seems to point to the following new line:

	INTERRUPT_RETURN_NMI_SAFE

Replacing this with the NATIVE_INTERRUPT_RETURN_NMI_SAFE that appears
elsewhere did not help.

Over to you!
