3DLabs Releases Linux Drivers
wilfie writes "3DLabs have released linux drivers for their for Wildcat III and Wildcat 4 Graphics accelerators. Being closed source they'll taint your kernel, but what the heck. Press release with penguin-friendly quotes available too." DataSquid has a note about ATI's Linux support: "While on the job hunt, I came across this posting at ATI seeking a project team lead. Last on the list of key responsibilities is "Act as a leader to improve the overall quality of Linux support at ATI." Good news? Certainly better news than what was suggested before."
What happened to it, were they fired, or move to some other department?
This is the kind of statement that taints the integrity of the ope source community, and is a prime example of why few commercial companies support Linux.
You will never "find" time for anything. You must "make" it.
Indeed. ...but what the heck.
If a cop came to your door and demanded to search it (sans warrant), would you say "what the heck"? Linux is about freedom.
Press release with penguin-friendly quotes available too.
Kidnappers lure children with candy. "Penguin-friendly quotes" do nothing to ensure my freedom to modify the source. This is just candy-coated oppression.
Looking at the plethora of video cards with differing amounts of VRAM, performance specs, drivers for Linux, stability problems with Windows (especially newer OS versions and Service Packs which often make video drivers unstable), I've got a suggestion.
Why not make a commodity video card with about 8MB video RAM (a Mattrox 8MB card out-performed a 32MB S3 hands down), and a stable open-source Linux driver? Will this lead to commoditisation of the video card and drive all other mfrs to imitate?
Just wondering...
If you keep throwing chairs, one day you'll break windows....
Are the card companies afraid more of revealing technology to their competitors, or of revealing their benchmarking cheats...er optimizations?
I am just taken aback that these drivers are not Open Source. The Open Source developer community would have a lot to contribute to these drivers; they could enhance the performance, add new functionality, and make them more robust. Their dedication and insightful would allow the chip makers to reach new markets.
It bothers me that corporations cannot see the long-term benefits that the Open Source developer community has to offer. It's a vast market and when it comes to high-quality graphics it's making inroads in an area dominated by SGI and the Amiga.
Only when we unleash the power of Open Source can we convince Matrox to decrease the retail price of the Parphelia.
Wearing pants should always be optional.
I has to be closed source, so application specific cheats^H^H^H^H^H features wouldn't be so blatant. I wouldn't expect any graphics card driver from a manufactorer to be Open Source.
(This sig intentionally left blank)
this may be slightly off-topic, but how do these "workstation-class" video cards perform on the tasks average computer users would do... gaming, etc. are they a better card for something like quake 3 than something i might get in a high-end gaming machine, or are they specifically designed to do big number-crunching tasks like rendering?
... people were paying $300 for a piece of irreproduceable hardware, and *support* to come with it. I guess they are afraid of the drivers that come bundled 'free' with XP as well.
If they help Linux, they should be open source, but this is a start.
Yeah, it is probably illegal or something like
that (DMCA violation or the like I am sure) but
OTOH, when you shell out between $300 and $1500
for a 3dlabs I would think you "own" it enough
to make it work on your system.
Its really good to see that ATI are sorting out the linux debacle withe their drivers, hell even BSD has better support than Linux and that isn't even a graphics intensive system.
Hopefully what they'll do is make it a completely open source effort so that their drivers can be tweaked to suit each individual kernel and so that directx support can be added. Given that ATI are making the fastest graphics cards on the planet at the moment this has to be one of the best bits of news I've heard all week.
All that glitters has a high refractive index.
3DLabs have released linux drivers for their for Wildcat III and Wildcat 4 Graphics accelerators. Being closed source they'll taint your kernel, but what the heck.
The heck is that we can't port them to other systems and platforms
I don't see why hardware drivers are not made open source. Considering these companies don't make any money off of the drivers, and instead only make money off the hardware, how do they benefit from keeping the drivers closed source. This only means that there's a smaller number of people who are able to use their hardware. It also means that they are loosing out on improvements that could be made by others, making the hardware more valuable. There is no reason to keep these things closed source
Anthropic principle: We see the universe the way it is because if it were different we would not be here to see it.
These are not Linux drivers. These are Red Hat 7.3 drivers. I'll stick with NVidia for now, thankyouverymuch.
I see you don't know much about video cards.
is will their best card with their driver burn
smoking rings around my nvidia card with nvidia's
drivers the way that nvidia cards with nvidia
drivers burn smoking rings around ATI cards with
ati drivers under linux? I tell you this... If
ID does a 180 and doesn't release a Linux version
of Doom3 at the same time, or a reasonably short
time after the windows version, I'm getting
whatever card is fastest under XP and giving up
on Linux gaming altogether. It's really nice
having a quake3 link in my blackbox menu, but
I'm already sick of having to reboot to play
counterstrike, NOLF2, and other games.
For every annoying gentoo user, are three even more annoying anti-gentoo crybabies. Take Yosh from #Gimp for example.
Well, since they've only released rpms for specific kernels that are shipped with redhat 7.3, I don't know that you can say they're supporting linux, so much as supporting a very small subset of linux.
Too bad if you need to step outside the box, but then, if you're using high-end workstation graphics software, that's probably something you don't want to do, since the software's probably targeted at the same place. You tend to lose support from vendors quickly, even tho 99% of the time, the differences mean jack, unless the vendor's got crappy software to begin with. (you hearing me oracle?! your installer is a PITA)
Still, redhat 7.3 is miles out of date, and that you're SOL if you need to say... use your own kernel for some reason, or hell, NOT use redhat at all.
I really hate companies that do that. Redhat's always been far more annoying to configure and use than I'm even remotely interested in dealing with, and they keep making it more useless every time they make a release. Hell. I'd happily tell people to use windows than deal with the annoyances that come with trying to use redhat to get stuff done.
[end generic rant]
If course, since I just ragged on the HOLY REDHAT, I'm probably going to be on the receiving end of a massive moderation smackdown. oh well.

from ati support
Please note - ATI Customer Care has NO INFORMATION regarding:
* which ATI chips or products are supported in a particular version of Linux or XFree86
* how to configure Linux for a given ATI chip or product
* when or if drivers are being developed to support ATI chips in a given version of Linux or XFree86
* what features these drivers might have
In short: we dont care about this.
In other words: if more people decide the buying on the quality of the linux drivers we would improve it.
This is a sad offering. They only support specific, official RedHat 7.3 kernel patchlevels -- i.e., there's no compilable kernel module like NVIDIA uses. This somewhat limits the audience for these drivers -- certainly makes them useless for me. I'll stick with my Quadro.
Cantankerous old coot since 1957.
Taint may well be a technical term but the common usage of the word evokes very negative images, and its usage here is clumsy at best.
Tell someone who doesn't know this technical term that their system is tainted and they'll probably panic, imagining that their PC has been hit by a virus, trojan horse or other undesirable event, where the reality couldn't be further from the truth. (We'll leave the debate about the pros and cons of closed source drivers to another discussion.)
There's got to be a better way of describing a kernel that contains closed source software that isn't so dramatic or apocalyptic. How about "ajar"? At least "ajar" is a better, less ambiguous, description - to me it says "not 100 percent open, and not 100 pecent closed", which is what we're talking about.

I hate to burn karma on something so silly, but really folks, you sound uneducated when you fail to observe simple grammar rules.
3DLabs is a single entity, and therefore the sentence should read "3DLabs has released"
That grates on me as much as "boxen" and "virii".

My problem was DVD playback. I got RTCW etc working with my 9700 and it was nice.
But try a DVD and only the left side of the movie was shown. I couldn't resize or swap to full screen to show the whole picture, it would always only show part of the picture. None of the rest of the desktop showed similar problems so it (hopefully) wasn't thinking there were two monitors plugged in. I never got it fixed and the ATI site hasn't updated the drivers yet either.
Back to the old matrox G400max now. No RTCW but I can watch DVDs.
[Off Topic]: "Here, here" should be "Hear, hear" as in heralding or verbally broadcasting support for something that another has said. Like saying "Listen to what this person has to say!" [On Topic]: Must graphics drivers necessarily be 'linked to the kernel' and result in setting the 'taint flag' as others have discussed here? Why can't the driver simply be a part of a dynamic library or similar (I probably showing my Linux ignorance here, so be gentle)?
. . . nope. That's not working right.

Best comment in this whole article. The chest-beating freedom brigade is, in my experience, a tiny minority that would be better off putting their out of control zeal into, say, Christianity, for all the good their tired preaching does anyone.
I know and work with dozens of people and several local companies that all use Linux, some a little bit (router, etc.) some as a core feature of what they do (file servers, mail/web serving, etc). And they all do so because it's cheap. No other reason.
Get over yourselves.
We have this issue about 'optimization' or some people like to say 'cheats'. But can't we make a driver that is optimazed for many things?
The driver would see, oh you running game X, will load these parameters now.
Or perhaps a different Video driver modual that loads depending on the application?
The Kruger Dunning explains most post on
Although I'd really like to see a driver that installs on something other than RedHat (how about a plain tar.gz maybe?). It shouldn't be that hard to repackage.
The driver works with kernel 2.4.18, so I don't know why so many people are complaining about only supporting old kernels. It should work with any system with that kernel (it might work with any 2.4 kernel), even newer and other distros.
I assume they recognized that there are tons of 3D movie, animation studios, and medical research labs that are all moving to Linux. 3DLabs provides some of the higher-end workstation-class graphics cards used for 3D work.
The ratio of people to cake is too big
It's too late for ATI to win me back. I've had so many problems with their products and/or the companys tech/customer support that I'll never switch back. NVidia ALL THE WAY!! The only way I'd use ANYTHING from ATI is because as far as I can tell, they have the best setup for the CableTV input card. I have one of those, but I'm using it with a Dell GeForce2 GTS card. Digital-VCR is pretty cool on the computer. I only wish I had a TiVo or at least a TV-out to use with it. Oh well :) Oh, anyways. As I was saying... I'll never use a ATI GPU ever again.
That's the point.
By using closed code in your kernel you are putting an unknown in it.
This is bad, the kernel developers can't help you, you can't fix it yourself, you're just stuck with broken software.
I think removing the ability to fix a problem is a dramatic change, particularly when that is a major benefit of free software.
Thanks for the (OT) correction. it is late here. There are some companies out there that do in fact do this. Sigma Designs drivers for the EM84xx chips have a GPL'd kernel driver and a closed source shared library.
The only issue with this is that even though the kernel driver is open source, it exists purely as a "RING 0 gateway" for the shared library. So if bugs exist, they cannot be fixed by the open source community.
it is only after a long journey that you know the strength of the horse.
Develop and test a user space driver for X Windows, 2D rendering and other non-3D related functionality.
Well here of course.
When all is said and done, nothing changes...
They fixed their Windows drivers, so let's hope they can do the same for their Linux drivers. ATi's cards are fairly nice; certainly a little better than the dim-looking GeForce FX line, and I say that as someone who is completely neutral when it comes to corporations. (No reason to make generalizations about anything except their products. Unless they're Rambus, in which case they're evil.)
Amusingly enough, the only nVidia card I'd recommend buying right now is their Titanium 4200, the very card that taught them a valuable lesson about market segmentation. In case you missed the whole thing, the Ti4200, Ti4400, and Ti4600 were spaced about $50 apart, except they had a performance difference of maybe 2-4% between each of them. The Ti4400 cannabalized the Ti4600's sales, then the Ti4200 cannabalized the Ti4400's sales. (ATi learned this too with their Radeon 9500 Pro, a fast card selling for less than the Radeon 9700 despite the small speed difference. They were quicker to react than nVidia, though, and stopped the 9500 Pro's production run short. Now they make the Radeon 9600 Pro, which is considerably slower than the old 9500 Pro.)
Up until now, 3D Labs has maintained a link to Xi Graphics for Linux drivers for the Wildcat cards. (www.xig.com)
So my question is this... are these drivers just a free re-release of the drivers originally built by Xi? Are they totally new drivers written by folks at 3D Labs? Are they from a combination of the two?
I'm curious (for both political and practical/technical reasons).
I've been trying to get mine to work for ages. The version of XFree86 that comes with unstable is 4.2.1, the 'ati' drivers that come with XFree don't seem to work, and unstable comes with glibc2.3, and the binary ATI drivers are compiled against 2.2 only, so they don't work either.

Also they only supply the drivers in rpm form, not even a
Does anyone have any ideas how I can get my 9800pro working in Debian unstable please? Changing distro is not an option! Ever!!
The problem with slashdot is that most of its users were bullied and stuffed into lockers as kids!
Now if there were just some nice 3D CAD programs for linux. I tried all the free options and they stink. This move by 3Dlabs suprises me because I wasn't aware there was even a single available high end (read: expensive) 3DCAD program for linux.
Anyone know of a good midrange option? I wouldn't mind paying a couple hundred bucks even.
then you'd know about the Open Source Bios along with CPUs, Motherboards and other support stuff

Oh and a FEA tool would be sweet too!
In a related note, S3 graphics has released open source drivers for the S3 Savage graphics family. See eg. here.
I have been observing that most of the notebooks dont use Nvidia graphic cards. Instead they prefer using mobility Radeon or some cheaper on-board cards. This is problem for me, because I am looking to buy a notebook on which I will install linux. Nvidia has fantastic linux drivers, so I wont have to worry about hardware 3D acceleration, if I buy a notebook with Nvidia graphic card. But I just dont see any notebooks in the market with Nvidia graphic cards.
How does Radeon behave under linux in notebooks? . How is the 3D acceleration in mobile Radeon 8500+ ? Are the opensource drivers good for full screen DVD playbacks? (I usually test hardware acceleration by playing TuxRacer)
If you have the time/initiative look into gentoo.
Heck, during the install you have to even setup a syslog to run, or you won't even get that. Even after I emerge a new app (say samba) it doesn't default to it running at boot.
Even slackware doesn't compare to that. As slackware usaully has ssh, sendmail, and a couple others running. The sendmail thing really bugs me though, since sendmail definitely needs a little bit of configuration before it is run to do anything useful.

Fact: We deserve leaders who can kick your ass and field dress your carcass.
RedHat 7.3 is older yes but it's been around the corprate world and is about the current level of support. I work with a lot of comercial linux software and for most redhat 7.3 is the latest supported version. As for rehat in general lets face it support bugets are only so big so you pick one release of Linux and go with it why redhat? Well for starters thats the version thats officialy supported on IBM Big iron. They have the RHCE program so you can at least get a person with some paperwork behind them. And finialy they have there server version with a slowed down release cycle. One of Linux's major program with big corprate acceptance is it's quick release cycle remember in a big corp envirnement it may be 3 months of testing before a new release is certified as production. Thats a lot of man hours that they only want to expend every now and again not every 6 months on the upgrade tredmill.
Now it would be nice if they took Nvidia's approach a chell script that does all the heavy lifting including a custom compile.
No sir I dont like it.
Well, maybe if you use Linux.
All I can say is, I run an All-in-Wonder 9700 Pro under WinXP, and ATi has been really nice about support.

I thought the drivers for ATI are great. Clearly, much better and more OSS friendly than Nvidia. I don't understand your reasoning as to why the ATI GPU's are bad. ANd btw, you are talking about a Geforce2 GTS card? :)
:)
Almost everyone knows that the story about ATI discontinuning the drivers was a fake rumour, that was spread while ATI was updating their site. Heck, it even said discontinued for the MAC and XP drivers for 3 hours before they fixed it all (within 6 hours).
I use an ATI Radeon 9700 and it's simply great for 3D work (Maya under Linux) and games (UT2k3) and Wolfenstein.
Well, from the lack of examples as to why ATI is bad, I think you are trolling
"How about "ajar"? At least "ajar" is a better, less ambiguous, description - to me it says "not 100 percent open, and not 100 pecent closed", which is what we're talking about."
Or better yet, how about "ajar-jar"? That way we can hook the Joe Sixpack crowd with the sheer cuteness of the term, along with the 3-6 year old user group.
Why do users with IDs under 100,000 or over 700,000 usually have the most worthwhile comments?
I suggest a new term: It'll give you "kernel herpes."
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
Congratulations to 3Dlabs!
It's very important that people who use cards of this sort (or who plan to make the jump) email them and encourage them.
On reading this, I immediately sent them an email, congratulating them on their move to support linux.
I am an (otherwise happy) owner of an ATI FireGL 8800, but next card I'll be buying won't be an ATI, unless they change their linux policy. I'm not impressed by that they just list it (at the bottom of the list) as a priority, either. ATI, beware!
The only "affordable" workstation cards I know that have linux support are nVidia-based. (PNY Quadro FX series at www.schneider-digital.de)
3DLabs has a _very_ interesting VP range. I wish they 'bless' that series with linux drivers as well. Up till now they were out of the question *just because* of their (lack of) linux support.

That is not a good sign, unless they are planning to release specs to the community for 3D driver development.

I want 2D games back.
Great, now everyone and their dog will be applying to ATI now that they have received free advertising on Slashdot. They are one of the few places that are hiring. I'll never get a job there now. Bastards.
Recently Creative have done a fair bit of interest/benefit to the open source community, including:
Open sourcing their first stage OpenGL 2 compiler. (To drive adoption, this is good for us because OpenGL2 will work with Linux, DirectX doesnt.)
Providing information to develop open source drivers for Creative soundcards, including the info needed to develop the Audigy drivers and other associated kit - and hosting the development on their servers.
Releasing Linux drivers for their high end kit, showing their support publicly for the platform.
Sure, all this stuff benefits them too, but that's the point of Open Source stuff - scratch your own itch, and then let other people use it.
I know these latest drivers aren't open source, but that might change with time if they see a benefit from their other investments in the area.

A monkey is doing the real work for me.
Anyone else out there have any experience with this combination? I recently upgraded from RH 8 to 9, and found that I would be lacking 3D acceleration. Anybody have any word on whether my 9700 Pro will ever run accelerated with RH 9 and XFree86 4.3?
Simply say "No" to any closed source driver dependent products. Message the hardware community that if they want the open source community's business they must be, well, open source. If ATI supports Linux with open code, then buy ATI. The ONLY weapon we have in this war is our checkbook.

Who ever gave you Troll is an Asshat.
This move by 3Dlabs suprises me because I wasn't aware there was even a single available high end (read: expensive) 3DCAD program for linux.
There's more to high end graphics than just CAD.
Someone in my office just set up a machine with a Wildcat card for 3D visualization of oil and gas reservoirs. This fits in with the press release: 3Dlabs' Wildcat4 and Wildcat III customers in oil and gas research, life sciences and high-end Digital Content Creation (DCC) markets will now experience increased productivity, cutting-edge performance, and superb graphics quality on Red Hat® Linux® version 7.3.
He is new to Linux, so naturally went for the 'latest and greatest' Red Hat (9), which gave him all sorts of trouble (with the graphics.)
I gave him some help, and he dropped back to RH8. Last time I talked to him he said he had it working. Don't know if he got it going on RH8 or went back to RH7.3.
Ignorance killed the cat. Curiosity was framed.
There's more to high end graphics than just CAD.
Sure, and hopefully this will open up more of the high end graphics market to Linux including CAD.
One stress as a Linux user is the lack of 'real' programs. By real I mean professional stuff like Photoshop, Solidworks, etc. Stuff that really seems best suited to a robust system like Linux.
There needs to be at least one online resource where I can find any and all videocard drivers in existance for Linux, including the ancient Diamond Monster Doodoo card I gots in my old box. It's depressing all these dead links and abandoned webpages that promise near-impossible-to-find drivers and then don't fullfill.

3Labs have been bragging about being top-notch amongst the cream of the crop of 3D hardware since the begining of time. And while their Wildcat series often shure kicked FireGL and others up and down the street performance wise, it was *allways* "Windows only". And nothing *but* Windows only. In fact 3DLabs and their Wildcats are among the very *last* to join the *nix crowd in terms of driver support for professional 3D. The FireGLs have had drivers form ages (in the 3D world that is) and just plain *everybody* and his freakin* brother has ported their 3D apps to *nix years ago.
Gees, 3DLabs, we might even get to actually be able to see your oh so superb performance. But believe me, Nvidia and their Quadro and other pro series have major credit with the *nix folk. They will have to prove their serious before people will actually take the time to check out their stuff.
Personally I think this is a very good sign for Linux. 3Labs are one of the most conservative 3D hardware vendors and even them adding Linux to their list means really good news.

This makes them useless for *everyone*. Anyone who uses RH as a workstation is using 8.0 or 9. Does 7.3 even support the new KDE/Gnome/XF86?
I still use 7.3 on headless servers because it's stable as hell. What does Dell offer on their servers? RH 8.0 or 9. Doh!
I'm ecstatic that they're supporting Linux at all, but, seriously, a lot of these companies need to be hit with a clue stick.
"I assumed blithely that there were no elves out there in the darkness"
Who cares if they get drivers out or not. Isn't the whole goal of being a Linux geek to code everyhting yourself? Do you not drool to the thought of compiling your own Catalyst Drivers for Linux? Am i missing something here? I'm not trying to get people upset or anything, i'm just very very confused.
If there's something i've learned, it's that there's always someone to code for you before you even think about doing it. For example, 3DFX's Voodoo 3000 drivers are still available for XP by a 3rd party. Wonderful geeks i kiss you.

I believe that 3DLabs is committing contributory copyright infringement (in the United States) by distributing lib/modules/2.4.18-3/kernel/drivers/char/drm/wildc at.o without providing freely redistributable source code to this file, because the only substantial use for some of the contents of this file is to produce a kernel in memory that is not permitted by the copyright permissions under which some parts of the Linux kernel included in that image are are distributed--i.e., the GNU General Public License.
I am aware of the additional permission that Linus Torvalds has given for linking proprietary modules, but he is only able to give such permission with respect to code for which he owns the copyright. I, for one, never granted such additional permissions.
To my knowledge, the proprietary XFree86 drivers are legal. I believe that 3DLabs only needs to release source code (under GPL-compatible terms) for their wildcat.o kernel module.
Certainly you have shown me that the word taint can have more malignant implications than I have given it in the past. I visited some quotation search engines to add to your entries above and found that it does in fact show up most often in a context of moral corruption, though in those cases it is often used in concert with a stronger pejorative and it does register in less grave circumstances (like wine spoiled by a bad cork). I stand corrected.
For the record I never claimed that "taint" means "to dye". I only pointed out its etymological undertone. Knowing such things can flesh out the more specific meaning of a word. I find that more usefull than thesaursus.com's suggested alternates such as dingy, slimy, or icky, though of course corrupted and impure come pretty close. "To dye" harmonizes a bit with the "something good gone bad 'cause something else got added to it" aspect of the word. Think "tainted meat". Hey, the meat started out good. It's the E. coli that ruined it for everyone.
I think the authors of the kernel and its support utilities chose taint because it indicates a fatal contamination. A drop of bleach in my Kettle Soda makes it undrinkable even though it's still mostly vodka and bubbly water. Dude, it's been tainted.
If you go here you'll find out why such indications are necessary. To the kernel maintainers, anything less than a fully open source kernel is just as bad as one that is mostly closed because they can't use a tainted kernel to fix bugs. Grep around in the source to modutils and you'll find you can taint your kernel with `insmod -f' too even if the module is GPL. The issue isn't OSS vs. Proprietary. It's "fixable" versus "useless kernel oops".
Even if this weren't the case I would still find "ajar" really awkward. Did you ever see The Simpson's episode where Bart cons his way into genius class? The teacher puts a math problem on the board and expects her students to "be pleasantly surprised". When everyone but Bart chuckles at the result (something like "R D R R") the teacher laughs and says, "Don't you get it Bart? 'R D R R'... Har Dee Har Har?!" Of course, what is funny about that scene is that the characters would find that funny, let alone "get it". I can't help but think ajar would strike people in an analogous way. Imagine it:
"Whoa, your kernel's ajar."
"What do you mean?"
"You know, ajar... half open, half closed?"
"Are you saying my kernel has a door in it... like a backdoor?"
"No. You know, partly open source, partly closed source..."
