ATI 3D Rage LT Pro AGP-133 (Mach64) Xorg DRI

This is where I'll be posting my crazy adventures in getting this AGP card working with DRI (Direct Rendering) in Xorg.

I've done it in Debian Lenny, so, surely it must be possible in Archlinux!

This card is integrated into my PII 400Mhz Micron Trek II Laptop from 1999 era.  Supposedly, this is the very first integrated AGP video card used in laptops.  Ever.  Although, I have my doubts as to Wikipedia's accuracy in this regards because I believe the Trident Cyber 9397 AGP came out sooner.  It's one of those questions we may never know the answer to.

I'm new to Arch (coming from debian), so I'd like to take a paragraph and comment on it.  What drew me to it is the i686 optimized packages.  The first thing I noticed is that I like it's fast boot time.  I haven't run bootchart yet, but I can tell it's significantly faster than debian out of the box.  Hopefully there's headroom for additional speed tweaks, but that's for later.   The second thing I noticed is that it's about 200 megs larger than debian's comparably minimal install.  I found that odd, but, oh well. 

Anyways, back to Xorg... one of the final hurdles in setting up a linux box.  Getting a display working is simple enough, and maybe 12 years ago having any kind of GUI would have been good enough, but not anymore.  On older hardware you need DRI in order to play video properly... not to mention run an snes emulator at a decent fps big_smile 

Note: for mplayer I can actually use -vo xv, since Xorg supports 2D accelleration by default.

I noticed that Arch has a package named xf86-video-mach64 6.8.1-1.  I thought to myself, "Can this be?  Will I get dri working out of the box with Arch?!"  The answer is no.  How stupid of me to think that may be true.  So, I'll be adding to this post as developments arise in my little quest.  Feel free to chime in with helpful knowledge, pats on the head, threats, and/or flames.

So, here's what I have so far... luckily, I have a pretty decent xorg.conf already setup and ready to go for this card... all I need are mach64 drivers, DRI, DRM, and all the other module goodies.

I can get into X, by typing startx... I get some nice default windows... First thing I notice is that ctrl-alt-backspace does not shutdown X!  I have to type exit into a console?!  That's a PITA, so I change that by inserting: Option    "DontZap" "false"   AND  Option  "XkbOptions" "terminate:ctrl_alt_bksp" AND editing /etc/X11/xinit/xinitrc to add in some lines...

As per the instructions at: http://wiki.archlinux.org/index.php/Xorg (thank you)

[gripe]Whoever was hitting ctrl-alt-backspace by accident... well... I won't say anything bad about anyone... but come on, people.  It sure as hell shouldn't  be neccessary to have to add multiple lines of code in multiple configuration files to re-enable the feature...  Which will probably break anyways once I add a window manager.[/gripe]

So, anyways, here's the errors so far:

Relevant Errors to console:

FATAL: Module mach64 not found.
(EE) [drm] drmOpen failed.
(EE) MACH64(0): [dri] DRIScreenInit Failed.

Relevant Errors in /var/log/Xorg.0.log:

Short story: the fatal error above is due to a failure in loading the mach64 kernel module, which caused the failure of the drm module, which caused
dri to not load, either.  So I learned I need to get/find a mach64 kernel module!  Using the locate command, I see I don't have a mach64.ko file.

So I found this old thread relating to the subject: http://bbs.archlinux.org/viewtopic.php?id=53071
^^^ which refers to packages that haven't been maintained since january...

PKGBUILD?!  What's that?  haha... So I learned about it here: http://wiki.archlinux.org/index.php/ABS … ild_System

I found the tarball on AUR for an unnsupported package (the one from february), and looked at the readme.txt

Preinstall:

You need your own kernel with the following options or the kernel from aur: kernel26-nodrm
Please make sure your kernel has been compiled without built in DRM:
        Device Drivers --->
            Graphics Support --->
                < > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)  --->  (CONFIG_DRM=n) Must be disabled.

While you are at it, if your mach64 card is agp: (These agp options are optional but recommended)
    Device Drivers --->
        Graphics Support --->        
            <M or *> /dev/agpgart (AGP Support)  --->   (CONFIG_AGP=m or CONFIG_AGP=y)
                <M or *> YOUR CHIPSET (CONFIG_AGP_**CHIPSET**=m or CONFIG_AGP_**CHIPSET**=y)

                For example, my motherboard is via-based:
                <*> VIA chipset support (CONFIG_AGP_VIA=y)

The standard arch kernel has DRM, so it will *not* work

If you need pacman -Uf to install, chances are that your drm.ko still is in your kernel directory, meaning that

... meaning what?  The text just ends, like a the directions to some lost, sunken treasure...  Sounds like I'd have to recompile my kernel.  Not a big deal (only a matter of time before I'd do it for fun), but I want to verify that I actually have to.  So, I checked the config for the Archlinux kernel and CONFIG_DRM=m... so it's modular... isn't that I want?  It's going to have to load drm.ko right?! 

I'm going to try building mach64.ko and drm.ko against the kernel headers for the arch kernel and see how it goes...

Update 1:

Ok, it looks like I do, in fact, need to recompile the kernel... or atleast, that's the next thing I'm going to try....

I can currently get glxinfo to report everything's fine... DRI enabled and such... however, glxgears has an abortion.   

Update 2:

After recompiling the kernel, I've learned that I didn't have to.  The information in the Arch Wiki must be outdated, because there's no reason to recompile to disable the modular support of DRM from the kernel.  Anyways, it still doesn't work (of course, I didn't have to recompile)... so the problem is with either the mesa, drm, or dri packages.

SOOOO... I'm going to downgrade until I find a version that works... stay tuned...

More to come!

glxgears (here's where it just crashes, though X continues to function just fine...)
Note1: I get roughly the same problem using any applications that use GL
Note2: The error for the drirc isn't a fatal error, so isn't a big deal in my experience.
Note3: No seg fault reported in dmesg.

So there it is.  I'm using the latest and greatest archlinux has to offer.  I've followed every wiki, and every forum post since 2004 that relates to DRI on the Mach64 on linux.  I've spent a solid 5 days on this, and can't resolve it.

I believe the problem to solve is this error:
*** glibc detected *** glxgears: free(): invalid next size (fast): 0x097031d8 ***

I also believe it's related to this reported bug:
http://bugs.archlinux.org/task/15354

Although, he was able to solve the problem by using newer drivers for his video card... I believe that the ones available in extra for the mach64 card actually are the latest.

I'm not a C guru (I'm more of a java guy), so memory management isn't my thing.  I don't believe that I could hack the source to solve any memory allocation errors (even if I could find the specific source file to modify). 

Perhaps I should try recompiling the mach64 drivers using the new mesa?  I don't actually know enough about that to know where to start, but it's the best idea I have.

The more I look into the problem, the more it appears to be a mach64 driver problem related to memory mismanagement.

Note:  I can get this to work in Debian Lenny, so it is possible.

UPDATE: I can't figure out how to compile xf86-video-mach64... I can get the latest with git, but it doesn't seem to include a Makefile... so I'm stumped. 

UPDATE2: Ok, I got them to compile (had to use autogen.sh), but it didn't solve my problem... So I'm onto recompiling mesa from git...  I'm currently stuck on:

makedepend: command not found



Ideas welcome.

Re: ATI 3D Rage LT Pro AGP-133 (Mach64) Xorg DRI

Solved!

I managed to recompile mesa from git source, and now DRI is working!  http://bbs.archlinux.org/viewtopic.php? … 57#p580357

then I 'copied' over the ne GL* libs to my /usr/libs folder, along with my  mach64_dri.so (heh, I had to make a symlink to it from /opt/gfx-test/lib/ due to my lack of understanding when I configured the mesa makefile using autogen), and the xglgears and xglinfo to their rightful places.

Sure... it's only 188 fps in glxgears (about 20 less than I got in debian) but oh well!  Better than the 27 fps I was gettnig using software raster!  At this point, now that I know roughly what the problem is (mesa) I can experiment with different versions of drivers, mesa, DRM, etc, and get back up to 206 FPS... perhaps higher!  Maybe throw in some compiler optimizations... who knows, the sky's the limit.

I'm sure it's buggy as hell, too, since I used the latest from git... I bet I'd get better stability/performance if I reverted some of the "improvements" big_smile
