Testing latest -intel in Ubuntu

[bridgman]

EXA vs UXA shouldn't directly affect 3D performance since it only handles 2D operations... but maybe picking UXA is also enabling GEM and you're seeing not-yet-optimized code in 3D-over-GEM ? Just a guess though...

[sezal]

Some compiz plugins (like Blur and Reflection) requires Pixel Shaders and as I understand Intel X3100 has support for this on hardware level. Can someone drop a light on status of Pixel Shaders support in intel driver? Is this somehow related to acceleration method EXA/UXA?

Sorry if it's not the right place to ask such questions, but I was waiting for Pixel Shaders support for last 2 years and every time I have upgraded to the new Ubuntu version I expected to get higher performance and better support and every time was upset with result.

So main question is - what we should expect with 9.04/9.10 (in addition to UXA/GEM support)?

According to some posts on the launchpad, 2.6.2 driver has some major bugfixes, maybe solving the majority of intel problems. Since it is purely minor bugfix releas, there is no point of not including it into jaunty. Are there any plans about it?

[tormod]

help is welcome

Intel has now released 2.6.3 with a couple of important fixes vs 2.6.2. These fixes are also on the master branch, so I thought I would update the master branch snapshot (2.6.99) for Jaunty xorg-edgers. It seems it also needs libdrm 2.4.5, so I uploaded this as well. However both my libdrm and -intel uploads are broken, but I don't have time to look more into it. If anyone can help out, there are two issues that I am aware of:

1. The libdrm build fails because of some libdrm-nouveau stuff that has been introduced. This is purely a packaging issue, which can be fixed by tweaking some files in the debian/ directory. Would be nice to have the nouveau support in the libdrm package, but this is of course not necessary for -intel.

2. The Jaunty kernel lacks support for "exec-fencing" and therefore the commit http://cgit.freedesktop.org/xorg/dri...20adb32141a358 needs to be reverted. This was straight forward last time, but now the surrounding code has changed so the patch can not be simply reverted. Either some git revert/rebase trickery can be done, or just unpatch the stuff by hand - this is an easy task that just takes some time. Unless more stuff needs to be reverted.

If someone figures this out, please send a patch, or preferably a debdiff against my uploaded source. Thanks for any contribution.

Tormod, I pulled libdrm-2.4.5 on March 1, and it built fine. It was actually my first attempt at using auto-xorg-git. It built perfectly, on my first attempt. I uploaded it to my ppa, https://launchpad.net/~kachristmas/+archive/ppa

I've had no problems building the latest intel drivers either. I have no idea how to do it with launchpad though. The newest drivers reference new constants in libdrm-2.4.5, but libdrm-dev will not over-write the header files packaged with kernel.

It's easy to work around using environment variables in debian/rules, but you can't do that kind of thing on launchpad.

I'm a little concerned that I'm not seeing the same issues that you are. What's worse, I know just enough about this stuff to be dangerous.

Hi kxmas,
The reason you don't get the same errors is that you are building from the libdrm package and not the drm-snapshot package. They will both provide the libdrm2 binaries, but drm-snapshot will also produce the drm-module-source package which is handy for compiling your own kernel drm kernel modules - built from the linux-core directory in the libdrm source tree. The intel modules are not maintained in linux-core any longer (only in the kernel) but for other cards this can still be useful (like nouveau). That is why I would prefer to get drm-snapshot working.

For building -intel, which kernel (headers) did you have installed? Did you get DRI or DRI2 enabled?

I should also mention to anyone interested that there are unofficial Ubuntu packages for the 2.6.29 kernels at https://wiki.ubuntu.com/KernelMainlineBuilds . I would recommend using those when trying out the latest -intel drivers.

Ahh, I didn't notice a difference between libdrm and drm-snapshot. I guess I lucked out and it worked anyway. Thanks.

I compiled with linux-headers-2.6.28-8-generic version 2.6.28-8.26 and drm-2.4.5. UXA, DRI, DRI2 are all working, and seem fairly stable.

Ok, I found some time to look at it and it was not so difficult. There were some upstream changes that needed an adjustment in the Debian packaging - libdrm_nouveau1 is considered experimental and is not built by default any longer. Enabled it again, and now drm-snapshot is fine.

And -intel turned out to build without problems this time, some compatibility fixes must have been added, or the Jaunty kernel has got the needed patches.

Happy testing 2.6.99.1+git20090303 those who dare!

It is also possible to test the latest kernel, also RC for *Ubuntu in deb.

[beecher]

apparently the tearing problem has been solved (see here: http://bugs.freedesktop.org/show_bug.cgi?id=19635)

but how can I apply the fix on Ubuntu Intrepid ?
