Free Software Friendly Graphics Card?
An anonymous reader writes "There's an interesting discussion on KernelTrap with a hardware company that is talking about developing a 'free software friendly' graphics card. The idea is to fully disclose and document all register interfaces including the BIOS, providing Linux and BSD users with a fully supported video card. The hardware engineer proposing the idea summarizes his viewpoint saying, 'the whole issue comes down to this: This is technically feasible. Should we do it?'"
Does your company have to divulge any proprietary secrets in order to leave everything open for this card? If so, is that okay or does that do them harm?

Can it be cool and still be royalty-free? Or are you going to get shut down by the big boys for stepping in their patents?
What? Create a functional and supportable video card that is platform agnostic and will just work? The problem is, it is too logical. Unfortunately, it won't work in todays economic environment. Unless you are screwing over your competitors, your customers, or your employees, you can't make a buck.
It's serving a small market(right now), requires thousands of man hours of design and testing, requires expensive fabrication equipment(too expensive for this company probably), and is unnecessary because current video cards work fine under Linux. At least well enough that spending $500 to buy a mediocre card by a small company is out of the question. And yes, it would most likely cost that much. With little demand, high development costs and high fabrication costs, it will be that expensive.

Until now, open source software has proven to be able to scare M$. Why can't open source hardware scare competitors of it's field? Obviously it's not the same but hopefully, if they all planned it well, and by the article it shows that they got a nice idea, I'm sure a project such as this would get sufficent support to progress.
"You and your third dimension."
Seriously. nVidia already has kick-ass hardware and the best drivers available under Linux, plus one of the best, if not the best, installer for Linux that I've ever used. It would probably take less effort to convince them to open up completely than to create a new card.
Do you have ESP?
So please do it. I know some Linux users take pride in their amazing ability to get some piece of not-really-supported hardware to function, and in fact there are whole companies which provide installation of Linux on unsupported laptops as their business, but this is not fun and is a waste of time.
When can I buy it?
Seems that most people here didn't bother to read the article. (Big surprise.)
This is a 2D only card. He would not try to compete with BigBadVideoCardVendor. He knows that development of a competitive 3D card is out of the question for now. But you have to start somewhere.
Unlike an opensource software project, an "opensource" hardware project can't "show me the code" in order to gain legitimacy and gather developer attention. He's looking to see if there is real interest so that he can make a case to his boss. He seems to understand the risks involved, and I hope he can make it work.

A nice useful mid range card at a competitive price. I'll take 2, To start with and more later. We are starting to sell dual boot systems at the white box store where I'm a tech and sales type. We have sold a few in the last 2 months, some Fedora, some Suse, and one Mandrake. A nice mid-range card supported on Linux and Win XP would be perfect. Just make it a bit cheaper than the Radeon 9600, with similar performance and I'll be able to sell the hell out of them. One of the biggest complaints amongst Linux users is support for video and audio.
Professional Politicians are not the solution, they ARE the problem.
It may be technically feasible, but what about financially? The interesting thing about open-source consumers is that they're mostly talk, but when it comes down to actually buying all of they stuff that they claim to want for Linux, they don't vote with their dollars. Just look at the failure of Lokigames to make a profit, not to mention id's big profile attempt to push Linux by doing a simultaneous Linux/Mac/Windows release of Quake III - sales of Linux Quake III were abysmal.
Expecting geeks to pony up a few hundred bucks for an open-source video card that has little if any chance of competing with ATI/Nvidia on speed seems pretty unlikely.
I currently own a couple of nvidia cards. I enjoy that NVIDIA is providing 3d accelleration for my installed software. What this Free Software Friendly board is capable of is minimal. It's essentially an ancient 2d acceleration. 3d support is off the table. I can find that elsewhere; I think there's a few OSS drivers that do that with proprietary cards. Perhaps they can't work on obscure platforms. I don't work with obscure platforms regularly, thats why they're obscure!
From a ROI perspective, you have to convince me there's some improvement over the status quo. I couldn't care less about the source. I know that 3d graphics are among the most alien software topics to developers. Its difficult, especially when you're mixing it with low level programming in a performance sensative environment. Not providing 3d means I'll look for a second card. More likely, I'll be looking at a different card that offers more functionality, even on Linux, at 50 dollars, than this can offer at 100.
Simply put, an free-software friendly board lacks a community to push it forward, and I don't see it treading water among the highly competitive graphics card market. If you want this to sell, you need to identify and explicitly cater to your niche market. Promote it as a learning tool, and grease the community wheels. Just putting it out there and expecting the world to recognize its value won't net you much.

Damn, there isn't a single good comment in this whole discussion... Does anyone here realize what a huge difference a fully-open videocard would make?
Yes, you'd have working drivers, which is valuable, but barely worth noting. The big deal will be the more advanced features.
HDTV is developing pretty well, and even if you can't get HDTV broadcasts, there's plenty of HD material on the internet. Unfortunately, most computers aren't fast enough to play 1080 material in any format, and I'd bet there's a few that can't handle 720 video encoded with MPEG-4, WMV, etc. The real answer is to have hardware decoding... MPEG-1/2 are all that we see now, and even that is pretty rare under Linux. I happen to be lucky on that front, but xvmc doesn't allow you to deinterlace before it's displayed, so it's fairly useless at this point.
When you have all the specs for the FPGA, you can just download the latest upgrade, and have full-fledged MPEG4/Theora/WMV decoding on the same videocard, meaning a 100MHz PC could playback HD-DVDs perfectly. No doubt Tivo would be equally as interested in the features of this card.
Even if you don't have a videocard powerful enough to decode your favorite codec, you'll still get serious gains from it being open. If you check-out mplayer's vidix drivers, you'll see that you can get serious performance improvements if the developers have the docs for the card. It's hard to explain what a HUGE performance boost you would get from having a fully-open card.
Plus, FPGA programming is getting a bit of attention lately. It wouldn't be hard to imagine companies setting up clusters of computers, and filling every available PCI slot with this graphics card, and using the cards to do most of the calculations. Remember the PS2 cluster? Imagine the processing power of that, but on steroids.
In addition, think of all the groups trying to setup display-walls, with multiple monitors. Being able to do that much easier with this card could make it a big seller, if nothing else...
As someone who has setup several Unix machines for multimedia, I think there would be a big market for this, even if it costs, say, $60, and has no 3D support. If you think you need 3D support everywhere, you're probably mistaken. If you're running anything other than x86 (or maybe MacOS on PPC) you've got practically no options for hardware-accelerated 3D anyhow. So, putting a 2D card in there, instead of wasting money on a new Radeon, makes everything work better, and you loose nothing.
Personally, I have only 2 suggestions.
1. Make it as cheap as possible, while still being fully functional. If it sells for $30 (maybe after a few months) I'll buy dozens of them myself!
2. Include as many output options as you can. I use S-Video a lot, but very few have interlaced TV-output support. DVI is important for those with LCDs. Composite looks like the next standard for HDTV output, and that could turn into lots of sales (especially if your card costs less than ATI's Radeon/HDTV adapter!). I've heard lots of cards don't work with HDTV well because they can't output an interlaced signal at HDTV resolutions.
Dual-head support would be very nice, at least if you can include dual overlay support with it. Then you only need 2 cards for a 4-head Linux system.

A path that could be very fruitful is to design a video card to be used in a TiVo-like device. In particular, in addition to the good suggestions involving the Render and Damage extensions, a 2D-only card should do some hardware accelerating of IDCT and motion compensation, so that i.e. DVD's and MPEG-4 files can be played with a very minimal CPU. Work with systems integrators that are willing to put MythTV on a silent fanless system with a pcHDTV card and your video card/chip. This could be a good way to go for smaller but demonstrated market, where the part is easier to design than a 3D-nvidia-ati competing beast. Actually doing the video and TV on the same part is a good idea, if it can be done, since these machines are usually space and PCI-slot constrained.
I do not think, out of the gate on a small budget is reasonable or feasable to get a 3D part. It would be better to start small, and plan some features for the second generation. For funding, take pre-orders. Oh and hype the shit out of it, on slashdot.
Secondly, how feasable is it to put a cheap off-the-shelf CPU on the part to handle the 3D workload. Certainly that's faster and cheaper than a FPGA. CPU's with MMX or Altivec instructions can be had in the 1-2 GHz range for < $50.

It might be more worthwhile to work on better relationships between Linux developers and Via. Via sells a large fraction of the motherboard chipsets (if it's not Intel, it's probably Via) and, as a commodity part manufacturer, doesn't have a strong business interest in a proprietary interface.
If Via can be brought on board (assuming it isn't already) that provides more leverage for dealing with other vendors, like nVidia.
Make an X.org accelerator - There are a lot of people who dont care much for pushing polygons, but would love to have a fast, high quality grahics card that intergrates with X.org or XFree86 and works without hassle.
Support multi-head operation with robust Xinerama support, good colour calibration etc. and provide hardware acceleration for compositing, video4linux overlays, SDL hardware blitting, X primitives, Freetype font renderers, DirectFB acceleration - this card could form the heart of every low-cost or embedded linux system sold in existing or emerging markets round the world, and provide significantly better 2D desktop acceleration than ATI or NVidia, who seem to put 100% of their efforts into appeasing the Doom3 players.
Even if its not a match 3D-wise to a Geforce FX6800, it wouldn't be hard to do a better job of supporting Linux APIs than 90% of the manufacturers out there.
