Kernel 2.6.35 and ati video card problem?

Wintervenom · 2010-08-13 04:50:27

If you do not want vertical sync, but you still want to use KMS, you need a patch for xf86-video-ati because it is hard-coded into the driver.

Hummm... using driconf I've disabled vsync without patching the driver. at least glxgears tells me that (1500fps aka more than 59.8fps vsync).

airstep · 2010-08-19 09:08:23

I have the same problem (only ~60 fps). Driconf didn't help -- when I restart program values become default.

I also have related problems, and using xf86-video-ati-git doesn't solve.

I reported here:

Edit.: Disable dynpm seems to solve.

I noted an error that might me causing this:
cat /var/log/everything.log | grep mesa
Aug 11 18:13:48 zapp kernel: You have old & broken userspace please consider updating mesa
Maybe mesa needs to be compiled against kernel 2.6.35, I'll try that later.

I got this too. I'm using an ATI Radeon and the problem seemed to start today after I upgraded my kernel to 2.6.35 on an (Athlon(tm) 64).

I get this message on dmesg:

You have old & broken userspace please consider updating mesa

This also keeps logging me out of my session and back to the login prompt.

I'll try to see whether some sort of mesa bug has been created upstream.

Cheers,

Chris.

Lol, i just have more.. I'm using kernel 2.6.35.3 from repo.
If, i boot my kernel with radeon.dynpm=1 - kms don't start because of "radeon: Unknown parameter `dynpm'".
If, i remove this option kms works, but SUDDENLY occures error, memory corruption, and my hard disks cannot be find by kernel, so i can't do anything
I can't say why this is happening.. but still problems.

I think i read yesterday that dynpm=1 is disabled in this kernel if using KMS.
See if i find that info.

EDIT: It was quick to find this, it was a link in phoronix forums: http://www.overclock.net/linux-unix/731 … river.html

Since kernel 2.6.35, dynclks is the correct parameter.

Maybe, but it's only a part of problem - i think memory corruptions more important

I think that is cause by vertical synchronize.
glxgear's fps will approximately the same as the monitor refresh rate.
But I don't know how to disable it though...

I don't think so. After I downgrade my kernel to 2.6.34, the fps grows to 500ps using vertical synchronize. I'm using hd3450.

Zapp! · 2010-08-24 12:42:27

I don't get the broken userspace error anymore (maybe because libgl got updated today?).

But the problem still exists. Passing radeon.dynclks=0 to the kernel doesn't change anything here...

Nibble · 2010-08-24 15:15:40

Same here, I also suffer from artifacts.

waylls · 2010-08-25 08:11:22

Lucky guys, i just want to start my system

Check out the wiki, there are several workarounds there: http://wiki.archlinux.org/index.php/ATI_Catalyst (for propietary drivers) and http://wiki.archlinux.org/index.php/Ati (open source alternative).

Yea there is a known bug AFAIK in fglrx when VSync is enabled to put the refresh rate at 30 Hz, which locks 3d apps at 30 FPS. I get that on my desktop with a 4870x2 when running glxgears. In order to disable forcing vsync with fglrx:

sudo amdcccle

This will launch catalyst control center. Go to 3d>Other options and move the slider to the left. You should be able to run glxgears and get a high FPS.

This can also be done using:

sudo aticonfig --vs=off

There is a separate option for video vsync, which I would keep on. It's enabled by default.

The problem still exists with kernel 2.6.36rc3. But, as previously stated, building the entire libgl/mesa/dri/ati stuff from git solves the issue. This seems to be the only way of fixing this until mesa 7.9 arrives.

Leonid.I · 2010-09-14 20:37:50

I can't say that we are in the same boat, since I use xfce, but after enabling KMS even "top" refresh became slow.

The card is Radeon xpress 200M, shared video memory; I don't use xfce compositing.

What seemed to help was

Option         "EnablePageFlip" "on"
Option         "EXAPixmaps" "on"

in xorg.conf.

On the bright side, KMS fixed my MTRR issues and also my glxgears finally started to make sense: ~59 FPS.

BTW, I have this in dmesg.log:

[drm:rs400_gart_adjust_size] *ERROR* Forcing to 32M GART size (because of ASIC bug ?)

which is a known issue. Does anyone know a fix for this?

I did rebuild everything (libgl/mesa/dri/xf86-video-ati) but still my 3D accelerarion was 10 times slower using 2.6.35 than 2.6.34 in my HD 4200. So I'm back with 2.6.34 and waiting any news here about improvements.

msx · 2010-09-20 01:29:36

I did try xf86-video-ati and can't make it work with latest x86_64 .35-4 kernel, however Vi0L0's Catalyst 10.9 module works quite well here, even faster than 10.7 (I jumped 10.8 because so much bugs and slowness...)
Hope this help you'll

Is there any mirror of git.freedesktop.org? My download speed is about 2k per sec.

This problem reoccured after xorg-server updates to 1.9 with or without the git version of tool chain. All of the windows are flickering, some parts of the plasma would turn black for a while then become normal.
any ideas?
