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:

How about trying?

#quilt push -a

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.

Whew!  ;-)

And from there you can follow the LTTng manual here :

http://ltt.polymtl.ca/svn/trunk/lttv/LTTngManual.html

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.

Ah, yes, my mistake.

quoted

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.  ;-)

Great !

Don't hesitate to ask if you have any question.

Mathieu

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

 *
 * (C) Copyright 2006 Mathieu Desnoyers [off-list ref]

....

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

It does indeed, see the patch I generated against 2.6.29-rc3:

	http://www.rdrop.com/users/paulmck/patches/2.6.29-rc3-ltt-1.patch

I get a similar failure on x86 -- perhaps my tools or build environment
does not match yours?

Maybe. If you want a quick and dirty solution, try :

CONFIG_IMMEDIATE=n

Immediate values are just an optimization, not necessary anyway.

K -- kicking it off.
