i810: libGL warning: 3D driver claims to not support visual

We are totally drifting away from the topic, please some admin move that away

I totally agree with the last post from BRPXQZME.
At work, I needed to fit a Linux Kernel into a 4MB ARM board.
I just grabbed the latest version of the Linux Kernel from scratch and trimmed and customized to include my drivers.
But on an x86 station, I reckon that Gentoo is the best distro I've used so far, even if a little high maintenance

My conclusion is you can use CVS with any distro as long as you know what you're doing. So just use the best one and stick to Gentoo.

moving back to the Xorg topic, and specifically the error mentioned on the subject line.

aren't we (the i810/i915 video chipset owners) using drm & i915 modules from the freedesktop.org for opengl acceleration?

i'm rather confused.... my understanding is as follows, correct me if i'm wrong.

1. we use kernel built-in agp support for the main-board
2. i810 drivers from xf86-video-i810 (modular X) to support the video chipset
3. drm & i915 modules (from freedesktop.org) to attain hardware (3D) acceleration

isn't mesa for software acceleration? where does mesa fit into this picture?

thanks,
shane

Not precisely.

According to the Mesa FAQ:

1.2 Does Mesa support/use graphics hardware?

Yes. Specifically, Mesa serves as the OpenGL core for the open-source DRI drivers for XFree86/X.org. See the DRI website for more information.

There have been other hardware drivers for Mesa over the years (such as the 3Dfx Glide/Voodoo driver, an old S3 driver, etc) but the DRI drivers are the modern ones.

Indeed, Mesa is for dri/opengl support.
If you look at the Mesa source you'll see drivers for dri on various video chipsets, including the i810/i915 driver.
The issue is that the driver for our video chipset included in the mesa source from portage is still incomplete and does not support some visual modes (23... etc).
This makes some applications and games slow or buggy and has been corrected in the CVS version of Mesa (according to Alan Hourihane, official developper for the i810/i915 driver).
This is why we are all waiting for the inclusion of ebuilds with these updated sources into portage (when they will be stable of course

)

ok, i have my machine configured according to the http://www.gentoo.org/doc/en/dri-howto.xml
and if you check, it mentions little of "mesa".

am i correct in saying that "the x11-drm package in portage supports hardware acceleration for our cards, and the mesa package is a rendering library that makes use of this hardware acceleration" ??

I feel like you guys are saying that mesa itself has hardware acceleration support for our video chipsets... which puts the x11-drm modules, and the mentioned guide at a questionable position.

BRPXQZME · Post by **BRPXQZME** » Wed Jun 28, 2006 12:08 am

Oh, x11-drm is kernel space, mesa is user space, and never the twain shall meet,
Till NVIDIA and ATI stand presently underneath Bill's feet!

*ahem* (the BRPXQZME does not make any claims to factual accuracy for this probably oversimplified and ill-conceived half-baked post, but only hopes to offer an explanation that simplifies it as best he understands)

Basically, DRI/DRM and OpenGL are very related but not the same. DRM talks straight to the hardware (because it's in the kernel). DRI is how X talks to that (as in "hey, uh, kernel, you handle this cause for some crazy reason they don' want me to take care of graphics from here ;_;"). OpenGL (provided by the Mesa project for most of us Linux users) is how programs talk in 3D, hopefully to hardware, expecting to be able to ignore nearly everything about how the hardware actually works... and if there is no hardware, then EMULATE IT IN SOFTWARE YOU !$@# $%$%#$ (which Mesa obviously does nicely). Mesa happens to also give you 3D OpenGL acceleration by talking to DRM through the DRI (to summarize it all in one sentence). I dunno, maybe I'll just link you to Wikipedia; it's kind of complicated to paraphrase.

The components in portage named x11-drm, libdrm, and mesa all contribute towards getting you better support for accelerated 3D graphics cards if you're using all open-source drivers. Of course, the binary nvidia and ati drivers replace (maybe only some) equivalent parts in x11-drm and mesa and (at the moment

) do a better job than the open-source drivers because they have all the hardware specs and pros whose job is to work on the code.

That sounds correct! Thanks for the nice insight

i915 dri module users should also track this thread

http://forums.gentoo.org/viewtopic-t-462307.html

for their performance drop. the thread applies to i915 dri module users only

HTS · Post by **HTS** » Mon Jul 03, 2006 10:59 pm

Still no fix? Did anyone submit this to Bugzilla? Let me check
Edit: Tried the new mesa, i915 driver is broken

juniper · Post by **juniper** » Tue Jul 11, 2006 10:44 pm

any solution yet?

dev-urandom · Post by **dev-urandom** » Fri Jul 14, 2006 12:09 pm

None as of now, from what i see. Damn, I am missing google earth

HTS · Post by **HTS** » Fri Jul 14, 2006 7:19 pm

Yes, finally some progress here!
The driver is NOT broken in:
media-libs/mesa-6.5.1_pre20060714

And I only get one of these warnings now:
libGL warning: 3D driver claims to not support visual 0x4b

and Warcraft3 looks much much better!

I think the next stable release of mesa will finally fix everything (well I hope so)

Where's that version from?

HTS · Post by **HTS** » Sat Aug 12, 2006 12:58 pm

Now using:
media-libs/mesa-6.5.1_pre20060810
Which now supports all visuals

It is from the portage-xgl overlay (aka xgl-coffee overlay).
But I think you can safely use the overlay just for Mesa if you don't use XGL. (And u can still roll back if not happy).

Yep. Works fine. I combine the Intel 1.6.5 driver with the Mesa and Xorg-server from the overlay and X runs just fine.

oh goodie. i am glad these are being ironed out. can't wait to get it running, but i think i will wait until it gets into normal portage. kudos to those solving this!

GoogleEarth still doesnt run for me after the mesa upgrade to pre20060810. I get an error:

do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try running with LIBGL_THROTTLE_REFRESH and LIBL_SYNC_REFRESH unset.

any tips?

You may also want to check for updated versions of libdrm and/or x11-drm .. i know I had to play with those when I was having issues with a i915 system

HTS · Post by **HTS** » Sun Aug 13, 2006 10:17 am

Okey, didn't try Google earth for a while. I will test it for you. brb

Unfortunately, installing x11-drm and libdrm didnt solve the problem. It gives the same error. I did a modprobe i915 and restarted X.

#emerge -pv x11-drm libdrm

Wow it is incredibly smooth, as never before.
I'm not sure which package you miss...

Wild Guess: probably your xorg-server or your i810 driver?
I am using:

How did you unmask the xorg-server?

My installation is as follows:

hi,

I've got the same problems...
I updated to:

but googleearth won't work.
glxinfo prints the following message:

and the slowly googleearth?
what I have to install to solve it?
My current kernelversion is gentoo-sources-2.6.17-r4...

i hope you can help me, too.

HTS · Post by **HTS** » Tue Aug 15, 2006 3:49 pm

Well since you have exactly the same packages as me, I don't see what's missing...
Do you run googleearth as a user? (don't run it as root).
