R600/r700 kms + 3d dri1/dri2

[Aostrich]

Thanks everybody for the information!

BTW, what is the best place now to take latest drm updates?
Should I take a git snapshot of the stable linux kernel branch and then merge Dave Airlie's drm-next branch into it? Or should I follow the mainline Linus' git tree instead?

I want to have the latest drm bits, but I don't like current linux-2.6.31-gits as they brake VirtualBox modules compilation...

When is 3D acceleration coming back to Karmic ...?

Just a day or two more than week ago after utilizing all from radeon PPA I've got 3D acceleration on my ASUS 3650 HD (a.k.a. ATI HD650) for the first time for the quite awhile. But that did not last for long. A day or two. Now it is gone again. When can I expect it back? My machine is fully upgraded according to xorg-edgers PPA and radeon PPA. Yes the numbers in gtkperf are lower that ever but I would like to try compiz, again, just for fun of it. I do not use it permanently ...

Maybe you upgraded to a newer kernel and did not rebuild the drm modules?

[zika]

No, I did rebuild and it happens in both kernels I use 2.6.31-999-generic and 2.6.31-11-generic, it also happened in 2.6.31.10-generic. DRM shows fine in dmesg and 2D acceleration is great.

You are not loading the modules from the radeon PPA, because they are patched to show another date, see the PPA page please.

Yes, I've noticed that but I'm doing just what the PPA states:

sudo module-assistant -t auto-install drm-modules

What am I doing wrong?
The important thing is that it worked and now it doesn't.
Any help would be greatly appreciated.

P.S. I've just checked and I have drm-modules source installed.
Now I see that there is only a file for 32-bit and my machine is 64-bit.
I'm not sure if I installed 64-bit several weeks ago or it was 32-bit also then ... I, simply, do not see how it worked then ... and it doesn't work now.
I'll reinstall both kernels and uninstall drm-... and wait for further instructions how to install it properly. (I thought I did ...)
My machine is AMD Phenom X3 with ATI HD 3650 (512M).
Now, after cleaning everything, reinstalling both kernels after I uninstalled drm-sorce and drm... generated with the command given above from PPA, with 2.6.31-999 I get

~$ dmesg|grep radeon
[    8.128965] [drm] radeon default to kernel modesetting.

[    8.131534] radeon: probe of 0000:01:00.0 failed with error -22

and with 2.6.31-11-36 I get

~$ dmesg|grep radeon
[   14.736302] [drm] radeon default to kernel modesetting DISABLED.
[   14.736982] [drm] Initialized radeon 1.31.0 20080528 for 0000:01:00.0 on minor 0

Thank You, again, for any kind of help. It is not so important, but it is intriguing ...

KMS+DRI2+3D works just great!

A small update after the weekend of dancing around my r700 KMS+DRI2+3D setup with shaman tambourine...

The biggest issue I've observed is Xv... It is not tear-free with KMS. There are visible artifacts (some color lines) appear on the video in both, windowed and full-screen modes. Switching Mplayer from full-screen to windowed mode and back removes them, but in a second or two these lines appear again...

After the sunday's update of ati ddx from Git, Xv became much better. I can't observe tearing anymore!

Regarding the color lines issue, it is still there, but I've found a workaround for it. I think this issue is related to colorspace conversions. I came to this conclusion as I observed the artifacts only in Mplayer, and not in tvtime. Tvtime uses YUY2 format, and Mplayer seems to use YV12, however I'm not sure. Adding "-vf yuy2" to mplayer parameters wiped the color lines away!

3D for me is quite OK (checked with ioqake3), except some artifacts in the bottom and rightmost 1-pixel lines. Probably this is already fixed in mesa.

1-pixel lines corruptions in 3D with KMS gone away since friday's Mesa Git update.
BTW, ioquake3 runs ~1.5 times faster with KMS and DRI2 than with DRI1!

So right now KMS+DRI2+3D on RHD4870 works almost perfectly for me.

HUGE THANKS TO EVERYBODY WHO HAS CONTRIBUTED INTO THIS GREAT JOB!

[Aostrich]

One more question, should PM Suspend to RAM work with HD4870 and KMS? For me it doesn't... However, neither it does without KMS...
After resume I have screen corruptions which go away only after rebooting the whole system.

[zika]

Now that 2.6.32-rc1 is out is there a point for me to pursue further trying to get 3D acceleration to work from xog-edgers (including radeon) PPA or should I just wait for tomorrow and try the new kernel ...?

[pingufunkybeat]

I've just tried KMS on a R710 here.

It works fine (1920x1080 fb console) until X starts, at which point it hangs with the mother of all hangs (even cold reset doesn't work).

I'll look around for potential solutions (it looks like pvtcupcakes' problem). I'm using 2.6.32-rc1 from www.kernel.org and all libdrm, mesa and ddx from today.


EDIT: Is there any kernel that is downloadable at the moment that works with KMS? I cannot clone the git repository of that size, it chokes at 10% and it's not resumable.
