Thanks, it does.
But even with that and similar kernel options, I get a
difference of 50% cpu usage between 2.6.9 and 2.4.29
in playing xine-ui.

Also if you change line 44392 of the referenced diff
file then you have pc speaker pich back and EVERYBODY
was waiting for that wonderful feature with avid
breath ;-)

hi all,
I compiled the kernel 2.6.7 with bruby patch. Everything is fine, I can
get multiple X .I successfully started 4 terminals on an Intel board,.
with some probels on X. My problem is that when i give the command
modprobe, an message come like "QM_MODULES function not defined". Why

Candidate multi-console friendly 2.6 scheduling?

Now have a working FC3.
Thanks for your work on ruby!

http://kerneltrap.org/node/4493
I saw this and couldn't help but wonder how it might perform,
particularly with the "unusual" load of multiple local consoles.
Towards that end I have applied the zaphod scheduler and gene algorythm
to my 2.6.9 ruby kernel. I have noticed a real change in CPU usage
behaviour. I've observed an adaptec hardware RAID array increase
throughput and other little improvements in behaviour. Reduced idle
load...

http://www.members.westnet.com.au/vanzeeland/Linux/kernel/patch-2.6.9-ruby.vz9x1.diff.gz
Here 'tis. Includes a lot of driver updates and other functionals too.
patch against kernel.org 2.6.9

I am wondering if this scheduler configuration might improve response
for multi console gaming and multi-console loads in general? The task
and anticipatory I/O scheduler tuneable variables will converge towards
the optimum settings for whatever load happens to be running. When the
load changes the schedulers converge towards a new optimum.

I am very curious to hear others thoughts. I've had a couple of days
uptime with it now; doesn't seem to have effected stability at all, and
seeing modest performance improvements. Notably quake3 was very playable
while recompiling a kernel; even on this dual Athlon playability would
previously suffer much more doing this.

Trying two heads of Unreal Tournament 2004 demo, one head in spectator
more chasing the other head around; bear in mind this is a dual 2800+
athlon with 2GbDDR, it took much longer to load the second instance, I
got good agp performance at 1024x768 and PCI at 640x480. The PCI
performance seemed OK, but nothing to write home about, bit choppy.

Quake3 showed improvements with two consoles at 1024x768. Good
performance on both. Previously both had worked ok but there was
noticable moments of lag but playable. Now both are smooth with no laggy
moments and I think I have a higher framerate, at least on the AGP
console.

James

P.S Trying to take it further, I would like to try this gene algorythm
kernel on some single CPU FC3 workstations; I tried to patch the ruby
inlining fixes to 2.6.9, however the following hunk failed, and I know
not how to fix it:
***************
*** 1372,1378 ****
        console_conditional_schedule();
        release_console_sem();

- out:
        return n;
  #undef FLUSH
  }
--- 1372,1377 ----
        console_conditional_schedule();
        release_console_sem();

        return n;
  #undef FLUSH
  }

is there a simple fix?

Four Heads on Intel Motherboard

[Vineesh <vi...@hc...>]

Hi all,
  Now i am able to get 4 heads on an Intel Motherboard(it has 6 PCI
slots). I tried with Nvidia, Ati Rage LT pro and Sis VGA cards. But this
setup only working with nvidia cards. But still there is some problem on
this setup too. Like garbled displays and like.

PS2 mouse entry does not show up?!

[drbista <dr...@ep...>]

Dear friends:

I traced out that the previous problems were because of the dependency 
problems and particularly related with the desktop distribution of the 
debian-based SimplyMEPIS-2004.06.

I have installed the patched ruby-kernel-2.6.7 from the c3sl site and it gets 
booted fine. But the problem is when I execute "cat /proc/bus/input/devices", 
it shows of 5 entries like below in vanilla 2.6.7 kernel, but with the 
patched ruby-kernel, the PS/2  mouse entry (the first one in the below) does 
not show up. And obviously, the PS/2 mouse stops functioning under the 
ruby-kernel. Any idea? For your perusal, I am including the output of the 
normal kernel:

nvidia 6629 under linux 2.4.XX

[Aivils S. <ai...@la...>]

Hi All!

	This is off topic a litle.
Under 2.4.29-rc1, 2.4.27 current Nvidia 6629 works for me. But i must
disable GLX extension .

GLX will work only after patching installation:
Remove under 2.4.XX undesired symbolic link
# rm /usr/lib/tls/libnvidia-tls.so.1
Create working one
# ln -s /usr/lib/libnvidia-tls.so.1.0.6629 /usr/lib/tls/libnvidia-tls.so.1

6629 provide two files libnvidia-tls.so.1.0.6629. Seems only one works
under 2.4.XX
This simple hack turn on GeForce MX 440, TNT2M64. GeForce FX 5200
(PCI) will not work.

Apply this patch after you applied ruby-2.6.10-nofb-20050108
on linux-2.6.10. I solved it the ame way when I made my 2.6.10-rc3-ruby
patch. (Unfortunately that never made it to the list, the attachments
made my mail too large. It's still in the moderator's queue.)
I am also on FC3. This patch also contains two warning fixes, one in

Re: ruby 2.6.10

2.6.10-ruby is still subject to the inlining compile failure under fc3 /
gcc3.4.2

Perhaps some of the kernel hackers and experienced coders here might be
able to explain what needs to be changed so this can compile under fc3
and others using gcc3.4.2 or therabouts?

I noted previously that the 269 ruby patch applies and compiles against
the FC3 kernel source tree. It does not compile under FC3 against the
stock 269 kernel tree. Although the ruby patched FC3 kernel compiles, it
has not behaved stable for me.

Is there a compiler flag that can be changed to prevent this compile
problem?

Or should we consider ruby incompatible with FC3 and/or this gcc version
in the meantime?

2.4.29-rc1 is out... so is bruby (with more PCspeaker)

[Jean-Daniel P. <jd...@di...>]

    As kernel 2.4.29-rc1 is out with some security bugfixes,
    I added the PCspeaker pitch corrections suggested by Hugo, and also
    I modified the bounding of speaker to VTs :
=09in the original bruby, the speaker is bound only to the first console;
=09in this last patch, the available speaker is bound to any existing VT.

    please test and comment :

Right. It tells you exactly what is wrong. At the risk
of repeating what you perhaps already know, Debian
kernels ship with what is called a cramfs file with
modules that avoids them filling up the kernel and
support the world and then some. This is invoked via
what is called "initrd". Use of this necesitates a
package:

http://packages.debian.org/testing/utils/initrd-tools

and what the messages told you is that you do not have
that package installed.

Install it and at least you won't get that error
anymore...

You are attempting to install an initrd kernel image (version 2.6.7-ruby)
This will not work unless you have configured your boot loader to use
initrd. (An initrd image is a kernel image that expects to use an INITial
Ram Disk to mount a minimal root file system into RAM and use that for
booting).

   As a reminder, in order to configure LILO, you need
   to add an 'initrd=/initrd.img' to the image=/vmlinuz
   stanza of your /etc/lilo.conf

I repeat, You need to configure your boot loader -- please read your
bootloader documentation for details on how to add initrd images.

If you have already done so, and you wish to get rid of this message,
please put
  "do_initrd = Yes"
in /etc/kernel-img.conf. Note that this is optional, but if you do not,
you will continue to see this message whenever you install a kernel
image using initrd.
Do you want to stop now? [Y/n]n

(I tried to continue with the n option and got the following)

And when trying to boot in the ruby image, it gave me kernel panic error 
saying the kernel could not find the place to mount....

Any idea? Thanking you in anticipation,

If /lib/modules now has /2.6.7 then after installing
what you cite with dpkg -i would probably install
2.6.7-ruby. But you can tell beforehand by examining
the .deb see man deb.

In any case I had better results with 2.6.9 Ruby, but
that was with a regular 32 bit kernel of course.

In Debian compiling a kernel is trivial with the
kernel-package package. Perhaps you know. "make-kpkg
--revision 1 kernel_image" gets you the deb in the
/usr/src dir. Get the .config file from /boot and
adjust with make menuconfig in a vc.

With 2.6.9 I was able to use the Debian source of the
kernel and use Ruby (i.e the 2.6.9 vanilla kernel and
the Debian patches added) but it will depend on the
kernel and if it does not fit you will have to use the
vanilla kernel. Sorry if this has been said already
and I am duplicating information. Aivils seems to
think that the main problem is the video cards. If I
were to do it over again I would first experiment with
many of those. As it is I only have 2 nVidia cards, so
funny looking garbage remains a questionmark...

A peculiar question, does the patched kernel 
( http://www.c3sl.ufpr.br/multiterminal/kernel-image-2.6.7-ruby.tar.bz2) at 
http://www.c3sl.ufpr.br/fourhead/howto-en.php when installed with dpkg -i 
command would install in parallel with the existing 2.6.7 kernel or replace 
the existing one? Any idea?

I wrote to the c3sl but yet to get any response for the last 48 hours! :-(

Thanks for help.

dpkg -l shows these two entries under xserver:

xserver-common 4.3.0.dfsg.1-6 files and utilities common to all X servers
xserver-xfree8 4.3.0.dfsg.1-6 the XFree86 X server

Does the above contain the isolatedevice feature built-in?

you can make a backup copy of /etc/kde3/kdm/Xservers and make a symbolic link

Probably no problem - just install both.  Problems happen only if
both programs wants to use the same hardware, I believe that
doesn't happen in this case.

When using debian, make sure you get your X from the testing
distribution. It makes sense to use the "testing" distro anyway,
as "stable" is so old.  The xserver from "testing" have
isolatedevice compiled in so you don't need to patch at all.
You can use stuff like
        Option          "IsolateDevice" "PCI:1:0:0"
in XF86Config-4 - it just works.

The screen section may need a
        Option          "InitPrimary" "on"
for xservers running on secondary graphichs cards (i.e. those cards
not initialized by the bios.)

You make changes to gdm.conf if you use gdm.
When you use kdm, you make changes to the kdm config file instead.
(Or xdm config files, for those who use xdm like I do.)

Not me.  I use a Matrox G550 AGP and a Radeon sapphire 9200 SE PCI.
One problem here - the radeon xserver is unstable and hang itself
(and sometimes the entire pc) occationally.  Bad hardware or bad driver,
I don't know.  I got a radeon because they were supposed to work well
in multihead configurations, even with 3D.  Unfortunately, it is older
radeons that work well. . .

I'm trying to get 64-bit going (amd64) but I'm going slowly.  There is
so many other things to do. :-/   I am currently stuck with 2.6.8.1
because later kernels simply hang when X tries to initialize the
PCI radeon.  [Not a ruby problem, it happens with plain 2.6.9 too. :-(  ]

Thanks. Have you ever tried with both (ltsp+multihead) on the same machine? 
BTW which distro you are using for multihead?

But I didn't see any mention of patched X server at c3sl site. And even Mr. 
Aivils Stoss specifically stated at  http://www.ltn.lv/~aivils/eng-xf.html 
that  "Since 15-MAY-2003 kernel patch You need not to recompile XFree86"

In any case, does anyone know where can I find the precompiled X-server for 
debian?

Anyone has any idea what are the changes to be made in kdmrc or other kdm 
related files? I checked 
http://www.tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/examples_dm.html but 
there is no mention of kdm-related stuffs besides gdm and xdm.
