Testing radeon KMS on Ubuntu

[tormod]

We have set up a package repository at https://launchpad.net/~xorg-edgers/+archive/radeon-kms which has kernel, libdrm, mesa and -ati packages for testing kernel mode-setting (and GEM/TTM/DRI2) on Ubuntu Karmic. The packages might install on Jaunty as well.

The above page also links to a Karmic-based live CD image (URL might change) which has all bits installed and simply boots up to the wonderful world of KMS...

Warning: This is experimental code so do not install it on your production system or anywhere where you have valuable data.

Be sure to have radeon.agpmode=-1 set in the kernel command line if you want to read anything. It would be rather annoying if I stated why.

Hello,
first of all I want to ask you if there is KMS support for an Ati Radeon x500 video card. (because this card is kinda old)
Secondly, I added the 2 entries in sources.list
But when I run apt-get update and the upgrade I don't see the kernel being upgraded and so this whole thing does not work. I am on Ubuntu 9.04
Thanks

I am not sure there is an X500 model but there is the rv370-based X550. I have tested this on X700 which is not much newer.

True, the kernel in the PPA does not replace the Jaunty kernel but installs side by side (which is good). Therefore you have to run:

apt-get install linux-image-2.6.30-8-generic

I would not be terribly annoyed if you used a sentence on saying why instead of saying that you won't. I reckon AGP mode is broken on KMS and agpmode=-1 forces PCI mode?

Just upgraded to karmic and installed all your packages from ppa regarding kms.
But I have issues when resuming from suspend. And where do I add radeon.agpmode=-1? When booting the kernel? Should I append that line in the grub menu? Because I already did that and it says unknown option or something like that.
I did notice the VT's having my monitor's native resolution. That is great But the suspend problem is really an issue

My suspend is broken with the non-kms 2.6.30 kernel as well, so it is not necessarily the fault of KMS in my case. Did you test plain Karmic before installing the KMS crack?

You can add radeon.agpmode=-1 to the "kernel" line in the grub menu, or for a more permanent setting:

echo "options radeon agpmode=-1" | tee sudo /etc/modprobe.d/radeon-kms.conf

Then just delete /etc/modprobe.d/radeon-kms.conf once the AGP issues have been fixed.

I tried the liveCD with an ATI Technologies Inc M56GL [Mobility FireGL V5250] which worked.
Then I tried to install the karmic packages on my jaunty installation. This did not work.
It loads VESA as default and if I force radeon via xorg.conf, it gives me:

xorg.log:

CS failure ...corruption... -22

while it still draws something, it is unbearable slow. It takes several seconds to just refresh the screen.

is perhaps something misconfigured missing? Id like to use DRI2, but I want to stick with jaunty.

edit:
just tried to wake up from suspend from the liveCD. It basically worked, but the radeon driver failed with the same message as when booting jaunty.

Thanks for the quick replies.
I did not tested Karmic before installing the KMS kernel. My bad
I created the radeon-kms.conf file but I see no change. So I don't know what this should fix
And another thing ... do you guys have plymouth packages for karmic in ppa?

[samentu]

Resuming from suspend I get: [drm:radeon_bo_move] *ERROR* CP is not ready use memcpy.
If I switch back and forth with CTRL_ALT+F1 and CTRL+ALT+F7 I manage to get the password prompt but on enter nothing happens. So I go back to VT1 and then back to X and I am loggen in but still can't see nothing but window borders and a lot of white and grey. And going back and forth again displays a new program if you managed to start one blindly from a terminal and so on.
And at about this time I get a lot of "*ERROR* Failed to schedule IB !"

All this only on resume.
