Hi everyone...

I finally manged to install Gentoo on my Pegasos using a stage3 tarball , but I've got a few questions...

1- With apparently no reason, after I returned from holidays, I encountered a problem during boot: it can't swith to hardware clock. Strange!

2- I wanted to use Bootsplash or some kind of graphical boot loader and I would like to know what are you using and how...

3- I'm not sure I've configured my Radeon very well, for I have a bit slow video playback (dvd playback forces sound to be crappy, I think it's caused by a lack of harware acceleration), so I wanted to know what kernel options did you set (I have a Radeon 9200) and if you followed the instructions in the ATI Howto found on the Gentoo website, which suggest to emerge the drivers like this:
# VIDEO_CARDS="radeon" emerge x11-drm
I didn't do it and wanted to know if you did, before I mess up more...
I was able to activate DRI, but found it very slow. Is it normal? I have a G4, with 512 Mb and my Radeon 9200 has 128 Mb... I think it should go faster!

4- Related to the latter, when I try to emerge the alsa driver it says I already compiled into the kernel, but I'm sure I have it loaded as module... Is that becuase I had to emerge the drivers before the kernel sources?

I would still like to try again with a stage1 installation, so if somebody did it with 2004.3 I would be glad to know what "arcane tricks" did he have to use! :wink:

Thanks!
:wink:

Hi RockmanX,

http://www.ppczone.org/forums/viewtopic.php?t=74 helped me solve the hwclock problem: boot morphos, start a shell and enter "Softclock reset".

That's it - voila.

Hope it works for you as well,
regards,
holger

We have a separate Gentoo Forum on this site. Please use this one in future for Gentoo-related questions.

I also had that problem. With hwclock I can set the hardware clock to my local time. Now it's better after a boot.

Currently there is no boot loader for the Pegasos. Probably a future version of grub will work. There is currently some work on it.

On the other hand, you see a boot-loader only for a few seconds, why do you want something graphical?

I use the boot menu described in http://www.freescale.com/files/32bit/do ... AN2736.pdf

DRI is really slow on the Pegasos. I use the top-recent X.Org-ebuild in Gentoo (it's a 8.2.0 release candidate) which fixes a lot of troubles with the radeon card. You can find my config at http://dev.gentoo.org/~pylon/config/XOr ... -PegasosII

x11-drm isn't used any more for X.Org.

Nope. If you have a 2.6-kernel everything is fine. You don't need alsa-driver as the kernel already fulfills the virtual dependency. And you should make it as a module. Read further on http://www.gentoo.org/doc/en/alsa-guide.xml

Many thanks!

Is DRI that slow because of the lack of ATI closed source drivers? Or lack of altivec optimizations? Or is it just too heavy for our systems? :roll:

Basically, we run only in PCI-compatibility mode, so this poses some inherent
restrictions to huge texture copies and such. Also, the powerpc doesn't seem
to have any kind of block write capacity. Altivec enhancement will probably
bring a certain boost here, but it still will be hindered by the missing agp
stuff.

Pegasos 3 will solve this issues.

So there's gonna be a Pegasos 3... And what changes will be required to solve this problem?

Well, i cannot comment about future hardware, obviously, and my comment was
meant that real DRI performance change can only be expected in a next gen
product, as the current hardware can't do more than pci-compatibility mode.

This is ok still, and later dri development certainly improves DRI
performance, and most free 3D games remain playable.

I wonder about cube though, did you really get this one to build on pegasos ?

Sven Luther

Another question...

@Pylon:

You're using the "ati" driver, but I knew it was for the closed source driver, unavailable for PPC... What's the difference if I use the "radeon" one?

@Everyone:

I'm trying the new enlightenment17 software (mainly the Entrance display manager) and couldn't get the Evas GL engine to work...
Did somebody tried it?

Wrong. The "ati" driver is just a wrapper driver, which detects the pci ids of
the graphic card and chooses the mach64, rage128 or radeon driver. There is a
problem with the radeon 9200SE though, since X is mapping the second pci-id,
the one from the second head, and not finding it in his database, and thus
chosing mach64, which obviously fails.

It has been age since i tried E, and debian still has 0.16 only, can't help
you there.

But is your DRI setup working ? What about running glxinfo and glxgears ?

So, is this correct, or shall I put "ati" for driver? Anything else?

Section "Device"
Option "BusType" "PCI"
Identifier "RADEON"
Driver "radeon"
VideoRam 131072
# Insert Clocks lines here if appropriate
EndSection

About DRI, it works, but transaparency and shadows slow down the system too much for me... I prefer responsiveness, so I have them turned off.
GLX works fine, and glxgears makes something like 395 fps... I use the -vo gl2 option for video playback with mplayer and have good performance, but not with DVD... (unwatchable)
If I don't specify the driver to play DVDs, I get average (acceptable) video performance, but flickering sound, so it's not good... Do you have the same problems with mplayer?

This is correct, you could use "ati", but it would only be usefull if you
where to put a rage or mach64 card in the box, which i believe you won't.

I don't use mplayer, so i have no idea about this, but i have no trouble
playing DVDs with xine and the Xv method. With peg1 it was problematic, but
the peg2/G4 is more than able to do it.

You should also add the following to your xorg.conf:
Code:
Section "Extensions"
Option "RENDER" "Enable"
EndSection
Try using mplayer with '-vo xv'.

Is the radeon driver RENDER-accelerated ? I think not.

Hey, does this mean that DRI finally works now with X.org? Should I
switch to Gentoo, since my system will still eventually chrash should I
enable DRI with X (I'm a Debian user).

You have a pegasos 2 ? DRI should work out of the box with the debian X
package, and also with the sid dri-trunk packages from michael daenzer, at
least with AGP cards. No idea about X.org though.
