I think this is i915 cards issue, sorry. You might get better kernel performance with kernel 2.6.30-rc4 which solves many other bugs: http://aur.archlinux.org/packages.php?ID=25304

Thanks I will try to compile tonight.

Re: Kernel26 2.6.29.1-3 decreases intel performance

It is the same crappy performance and bugs that were found in 2.6.29 with 2.6.3 xf86-video-intel except for the tiling issue. I've downloaded 2.6.30-rc4 from www.kernel.org and compiled it myself, installed xf86-vide-intel-newest from aur and no improvements what so ever... sad I'm begining to think that the situation with intel drivers will never get better. Lower resolutions are not switching in full screen (u get native resolution with framed window the size of the resolution you selected in game), redrawing message popups is still slow, glxgears 480fps, urban terror 20-22fps... sad

I have intel X3100 FYI...

I'm afraid I'll have to agree--I've been mixing and matching and tweaking since January, and the best performance I've gotten so far would've been with xf86-video-intel-2.7 + kernel-2.6.30rc3, which yielded about 65% of Q2 2008 package performance.

Re: Kernel26 2.6.29.1-3 decreases intel performance

I have similar problems.

Does anyone have this problem with the newest intel drivers? >>> http://bugs.archlinux.org/task/14594

hmm Endless story these intel drivers.

Re: Kernel26 2.6.29.1-3 decreases intel performance

No, don't have any freezes. But I was checking out similar threads and there seems to be a big performance drop if u have dual channel memory enabled (my case too). I had 1GB hynix DDR and since I couldn't find another hynix memory with the same chips I bought 2x1GB Kingston and thus have dual channel enabled. Performance suckZ ! This is what is on their TODO list:

UXA/DRI2:
* Virtual screen size limited to 2048x2048 for pre-965 platforms: bug#21190.
* front-buffer rendering broken: bug#19174.
* XvMC disabled: bug#20790.
* VT switch broken on some machines: bug#19578.
- KMS:
* This kernel patch is required to fix tiling issue on 965+ with KMS enabled: bug#21246.
* only native resolution supported: bug#20801.
* video overlay not supported: bug#20901.
* no user-level control for backlight: bug#20963.
- glReadPixels fail with tiling on some platforms with specific memory configurations: bug#18420,bug#18586,bug#19317.
- GEM kernel not working with PAE (CONFIG_HIGHMEM64G), so now GEM is disabled with PAE in 2.6.28+ kernel as a temporary workaround: bug#17993.
- 3D broken with tiling enabled on 8xx platform: bug#18878,bug#20473.
- G41 DRM support: bug#21095, with patch available.
- No support for DRI if screen wider/higher than 2048 px on pre-i965: bug#10479, to be fixed by shatter.

They already fixed the tiling issue, the rest needs to be patched... As u can see only native resolution is supported using kms...

Re: Kernel26 2.6.29.1-3 decreases intel performance

As suspected this bug remains in 2.6.29.3

Here's the compiled version of newest kernel 2.6.29.3-1 for i915 cards - download

Re: Kernel26 2.6.29.1-3 decreases intel performance

I do not have Intel as I have Via instead.  I got a real slowdown when I installed xorg and also the new kernel.  I thought the problem was xorg but maybe it is the new kernel.  For me the keyboard and mouse are not recognized very quickly and you can hit a key or move the mouse and it takes a long time for it to be recognized.  I am glad that others are working on other issues as maybe this will help me.  I guess I will have to make sure that testing is enabled so that I can get the latest kernel.  I will be upgrading my mother board soon and I believe that it might have an intel video on it so it is nice to see others working on the same problem.  I love these boards as I have learned more off of them then I have ever learned using Linux.

Re: Kernel26 2.6.29.1-3 decreases intel performance

Hey Guys,
I am sure happy to have found this thread. It seems to deal exactly with the problem I am having. But I have tried to follow your instructions but
things do not get better. I have a intel 945GM card.

The fact is I followed karabaja4's links to download the patched kernels. I downloaded the latest two (the .3-1 and the .4-1) and tried installing them. I am not an expert so I suppose I should do:

pacman -U <filename>

I actually did it and the manager seems to have installed something. I have actually no way of understanding if it actually has now patched my kernel (any tips would be great). I am having all these doubts because the xorg log file continues to display stuff about the tiling being broken... Maybe I will now try to find the even older kernels. However, can someone please tell me in they are also still experiencing this problem. And why does my system keep giving my the tiling error. All those people that had their problems solved by this patch: did the tiling error go away? And those who still have the problem: are they still recieving the tiling errro.

EDIT: I actually tried the 2.6.29.1-2 kernel and even that one gives me the tiling error!!!!! Is it possible. People are saying their problems began after the upgrade from version 2.6.29.1-2!!!   What is happening here?

Here is some output:

glxgears gives similar output with all 4 kernel versions i tried:

1074 frames in 5.0 seconds = 214.759 FPS
1126 frames in 5.0 seconds = 225.097 FPS
1049 frames in 5.0 seconds = 209.717 FPS

lscpi gives:

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

and my X log file (Xorg.0.log) contains the infamous lines:

(II) intel(0): [drm] installed DRM signal handler
(**) intel(0): Framebuffer compression enabled
(**) intel(0): Tiling enabled
(==) intel(0): VideoRam: 262144 KB

(II)         Solid
(II)         Copy
(II)         Composite (RENDER acceleration)

I am having difficulty understanding the output of pacman. Did it actually patch the kernel?:

Well, the kernels I compiled fix the problems with i915 cards. I am not sure if it will work with any other card, so you are probably better off with offical packages.

Yes, you upgraded the kernel package correcly. And yes, tiling error does goes away for me when I apply the custom kernel (reboot is required!). Try compiling 2.6.30-rc7, it's told that it fixes many problems.

P.S. For i915 owners - I'll put patched kernels on this website as they come along, latest version is 2.6.29.4-1: http://archlinux.pondi.hr

Re: Kernel26 2.6.29.1-3 decreases intel performance

I was having major performance issues.. Updated to [testing] and it's all good smile
Thanks for the hint on 2.26.30.x!

p.s: I've got an i810 - so perhaps this problem was affecting more than just i915 people?
