Hi, tranquilcool. Look at the first post of the following thread. There is a "QUICK GIT HOWTO" section for zen-sources.

I also found how to switch to master-devel by scanning through zen-sources thread

Code: Select all

git branch master-devel origin/master-devel 
git checkout master-devel

<-- was that the info you were looking for ?

what is the difference between master-devel and master-dev-rt, btw?

additional realtime-support ?

Removing static from line 36 in main.c allows compilation...don't blame me if it breaks something else though as I really haven't looked at the code >_>

A program to measure latency just got released by the Intel crowd. Needs a couple of kernel patches, see http://www.latencytop.org/download.php

Do not use master-dev-rt!
It is a broken branch for testing only.
It is likely to screw up your system.
At the moment it does not even contain much of the rest of zen-sources.
If it is ever ready for testing or even normal use, someone will announce here.
For more information ask b33fc0d3, he's the one who made it.

Waninkoko: Maybe you could add a note that people should stick to master or master-devel for now.

latencytop.h is missing in kernel src, its not just a wrong path..

edit: what about this http://lkml.org/lkml/2008/1/18/358 ?

Well, this means that something is wrong here, what is the last version of that driver? Is newer than the version on portage? Because my driver is the newest on portage, and you can see the result

That was the problem. I created an ebuild on my local overlay for the newest version of the driver, and it works.
Thank you

And what about svgalib?
Why you don't use gspca module included in zen-sources?

Porque no usas el driver gspca que ya viene con el kernel? Asi te ahorras el tener que recompilarlo cada vez que cambias de kernel ni tener que preocuparte por nuevas versiones.

Because I didn't know it was included

---
No sabía que estaba incluído, además, con los drivers, "normalmente" la versión de portage es más reciente que la del kernel

It's only included in zen and I always put the latest version

El driver solo esta en zen y ademas siempre intento meter la ultima version disponible.

Latencytop works OK. Icrease kernel size by 100kb. So tune your system and disable that (as other debuging info).

Thank you very much, I've added kernel driver and unmerge it from portage. Still no luck with svgalib?

Muchas gracias, ya he hecho el cambio de uno por otro. Sobre svgalib sabes algo?

hirakendu · Post by **hirakendu** » Sun Jan 20, 2008 9:58 pm

I guess I already suggested that if you don't use svgalib, especially the svgalib_helper.ko module in the kernel, then you can emerge svgalib with USE=no-helper. (In fact, there is no need to re-emerge svgalib then after compiling a new kernel.)

Is it possible to update the gspca driver? The driver in zen-sources is version 1.00.18, and this on http://mxhaard.free.fr/download.html is 1.00.20. It will be nice. I have a problem with my Logitech QuickCam Messenger web camera when using skype. When I start a video call, the cpu load jumps to 100%. I hope this is resolved in the new gspca driver.

Thank you!

This is not a gspca problem, as far as I can tell. (spcaview takes very little CPU) Skype does use a lot of CPU, though, for video encoding. Updating gspca won't help Skype's encoding.
(Note: I'm pretty sure about this, but I might be wrong.)

I think you are right, because I have high cpu load only when using webcamera + Skype. Exactly the skype process is this which eats all the cpu. With mplayer (mplayer tv:// ...) there is no such problem. Thank you for pointing in. I have found on the internet that this is a common problem and obviously a Skype related.

However, it will be nice if the version of the driver is updated (if is reasonable of course).

Thank you.

I'm pretty sure I updated gspca some days ago :S

'gspca' updated to 01.00.20

Maybe I pull from another branch. My EXTRAVERSION is still -rc7-zen2 and the Makefile under /usr/src/zen-sources/drivers/media/video/gspca says:
VERSION = 01.00.18

# git-branch -l
* master
#

Anyway, thanks for merging the new driver into git. I will wait just few more days for the official 2.6.24 and the official 2.6.24-zen1. The zen sources will be distributed as stand-alone patch file, right? Thanks!

Why are you using gspca driver? There is a specific driver for logitech quickcam messenger, quickcam_messenger. It works better? Just curious

I see the same. Ohh the agony of not being able to compile a new kernel.

Thanks for all the work put in zen-sources.

I'm not quite sure if I'm too stupid to use git or if there's a real problem with iwl3945 in current master-devel.

[*removed*]

Edit: It was the first option, somehow I screwed my local git repository

. Just did a clean "clone" and switched to master-devel as told on http://www.zen-sources.org/wiki/GIT_FAQ

Realtime Linux Kernel Development Tree

There is now a new branch called 'master-dev-rt' which contains the new realtime scheduler. Most of the clean patches that only add features have been added. Please test it.

Code: Select all

git pull 
git branch master-dev-rt origin/master-dev-rt
git checkout master-dev-rt
make clean

Regards,

kernelOfTruth · Post by **kernelOfTruth** » Mon Jan 21, 2008 6:25 pm

could you guys with a rig please say if something similar like in this post has occured to you

I dunno if it's related to newest kernel-changes but it hasn't happend with earlier versions (currently running master-devel with rc8-zen0) and it's also not reproducible with windows xp

many thanks in advance

RobertDavid · Post by **RobertDavid** » Mon Jan 21, 2008 6:40 pm

Is there some way to compile 32bit kernel with distccd on 64bit?? I just did that few times without problem, but now, I think till rc6-zen0, it gets some errors.

Code: Select all

  CC      scripts/mod/empty.o
scripts/mod/empty.c:1: error: CPU you selected does not support x86-64 instruction set
scripts/mod/empty.c:1: error: CPU you selected does not support x86-64 instruction set
scripts/mod/empty.c:1: error: -mpreferred-stack-boundary=2 is not between 4 and 12
distcc[6778] ERROR: compile scripts/mod/empty.c on 192.168.1.33 failed

the first error become with unselecting march=native (distcc worked before with it on same conditions!!!!)

the second error just appear when I change from rc6-zen0 to latest git

I have one older subnotebook with P3 600MHz and compiling kernel takes forever and looks like it will burn the notebook...

I have read somewhere that compiling programs between 32 and 64 bit did CFLAG -m32. So I have tryed to place the flag somewhere in the makefile but didnt work

I have same gcc compilers, same version (4.2.2), only x86 vs x86_64

compilation localy work nice.
