Hello all,
I, as a opensuse and NC20 user, am very interested in this forum.

Not beeing able to get the via drm driver to compile with kernel 2.6.32 R5
any advice would be helpful.
Can anyone explain to me the diffrence in performance
between the 32-bit and the 64-bit driver version in glxgears,
if there is some?
My glxgears with the 32-bit version and kernel 2.6.27 are ~ 420.
Regards
Uli

Hey, man, just forget this. It wont compile fine against 2.6.31 and I guess you will have the same stuff up there.
You will probably have to wait for Karmic driver to show up. All of us will probably have to.

By the way, an update turned up.

The driver I've introduced a week ago or something is now available at the Via, inc. website
Therefore the driver posted in n260 is not something special anymore, I guess it is reasonable to leave the manual there.

Glxgears will not run in 64-bit mode, this is because there are no 3d-drivers out yet. Until there will be some, you will have to stick to 2d only driver called openchrome. And even this driver only runs on kernel < 2.6.30.

If only there were fine 64-bit drivers.

When I started to use the nc20 (2.6.29.2), there were almost none drivers for 64-bit mode. And I had to do a lot of patching, but now I think most of them have been merged in the kernel. Anyway I will attach them including my kernel config.

Everything works, except the viafb framebuffer driver and the via 3d driver. If you compile your kernel you will have to select padlock-aes, padlock-sha, e_powersaver (safe on the nc20) and the via-rng module.

sha1 64bit-support:

I could not include these drivers, because they are to big, you will have to google for them:

Alsa-driver-1.0.20
openchrome

Cmon man, I am already using a custom kernel with Via HW RNG and Padlock incorporated. It is okay. Not sure about amd64 though.

Hello all,

I've ported the drm kernel module to kernels 2.6.31 and above (didn't check with 2.6.32rc though). The archive contains the chrome9 module sources modified with some patches I found in this thread and on the dri-devel mailing list. It works on my NC20 (tested with: kernel 2.6.31.4, X.org 7.4, xorg-server 1.6.4, 32bit only) in combination with the new binary drivers for Ubuntu 9.04. Feel free to test it.

Is there a way to include this patch in the ubuntu iso? Or more generally asked, what options do I have to apply your patch?

Does anyone here know whether the new 9.10 will be installable "out of the box" or whether the methods described earlier in the thread will still be required?

Also, is anyone aware whether any of the fixes we've had to use have been included in the new release?

Moldy.

Thank for your help.
I got it compiled with 2.6.32 R5.
Glxgears works, but googleearth freezes my system.
Anyone having the same experience ?

Googleearth works here, slow but usable. Did you try some other OpenGL apps (tuxracer, foobillard,...) beside glxgears?
What does dmesg say? Anything with [drm] in it may provide some clue...

Got it working. Compiled the via_chrome9 drm modul.
Recompiled the GFX-betadriver from August 2009 for the via_drv.so, took the libGL.so.1.2.chrome9 and the via_via_chrome9_dri.so libraries from the new Oktober driver package.
All works with kernel 2.6.32 R5 and 420 fps in glxgears.
