How can one write software that uses such a "good graphics card" if one does not have such hardware? I honestly don't understand comments like this. Should I stop writing drivers for these cards because we don't have any software available that uses all of their features? Next, people who would like to write software that uses GPU features will not bother because no drivers are available for the graphics cards. This results in a deadlock situation in which nothing ever gets done.

Interesting questions, I understand your doubts

If they don´t release the vblank data in the documentation, ask for it. Looking at how open they seem to be turning, I think they will inform you.

Regarding r7xx on pci...

Good to hear from someone at Mostoles (el mas allá ), I have family and even been there many times :)

But guess better. Examples:

- Not running out of graphic memory
- Renders and scrolls of OWB faster (modern graphic cards not only accelerate 3d, but 2D too, and VIDEO, and a lot)
- Realsoft 3D with better previews in realtime
- Allegro ports running at decent speeds
- Help Amidog complete his port of pcsx2 allowing him to watch it at decent speeds
- Mplayer and DVplayer playing HD content
- Hollywood handling it...
- Ports of games that need new shaders (and yes, there are a lot of them open sourced)
- Scene demos with new effects
- Doom 3 is going to release Source code just now
...

Do you need that I continue the list?

It is not an obsession for hard or being a graphic whore, but actually almost a needing, as very soon we will run out of available cards for the system. This situation is rather pathetic, and in this moment, hans' work is being a KEY piece for the future of the platform.

Sometimes I get kind of shocked when some people cannot see it

I already have asked and they told me that they would release that information along with other documentation. The one thing that they did confirm, was that it's quite different from the R5xx series. I am patiently waiting.

I'm not expecting these on PCI, but you never know.

And I vote for going 6xx series first, this world is moving faaaaaaaast...

True, however, the R5xx is easier to deal with so I'd probably make faster progress with the R5xx. What I do will probably depend on when I finally have my A1 again, and when the R6xx documents are released.

Please note that the released source contains the DRM part only, and a demo that interacts with the DRM. There is no DRI, so no 3D. However, they do have working 2D acceleration.

Do I get an extra week now?

Maybe I should give Canada Post a week, do deliver my machine. I'm still waiting for it to arrive.

Remember the future belongs to the GPU, not the CPU.

New material taken from Slashdot today...

Quote:

"To many observers, the success of the GPGPU landscape has really been pushed by NVIDIA and its line of Tesla and Quadro GPUs. While ATI was the first to offer support for consumer applications like Folding@Home, NVIDIA has since taken command of the market with its CUDA architecture and programs like Badaboom and others for the HPC world. PC Perspective has speculation that points to ATI addressing the shortcomings of its lineup with a revised GPU known as RV790 that would both dramatically increase gaming performance as well as more than triple the compute power on double precision floating point operations — one of the keys to HPC acceptance."

the story is great!

>>>> Make no mistake, 960 stream units provide a lot of raw power. I believe that AMD will also work to improve the double precision float performance of this product. The current RV770 provides 1.2 TFLOPs of single precision float performance and 200 GFLOPs of double precision float. If AMD could change around their stream units to give 1.7 TFLOPs of single precision along with 680 GFLOPs of double precision, they will raise more than a few eyebrows with this part. That 680 GFLOPs would be assuming AMD converts 2/5 of the stream units to double precision. Now, if AMD were to convert 3/5 of those units to double precision, a single card could do slightly over 1 TFLOP. One single video card could replace the floating point power of an 8P rack of high end Xeons, with extra performance to spare. Then consider that this card would pull around 180 to 190 watts at full load. Pretty impressive math, from nearly every angle. >>>>>

Impressive....most Impressive!

AMD has released a 392-page documentation on R700. Maybe it will be helpful in a future...

@Hans

how is delvopment going on

Hans hasn't spoken on this thread since December, so hopefully it's full speed ahead.

All the best.

-New Hardware
-New Software
-New Drivers

All of these are good news, as and when they come.

@Hans

Even if we had (full) drivers for (insert some insane GFX-card here), and if everyone would have them in their system ..... what SW would make use of it ? SDL-GL-games ? YAQP (YetAnotherQuakePort) ?

Those should run pretty well under currently supported cards, and everything else would probraly require a much faster CPU too (and more/better resources in $$ and developers).

So what should we do then? Not bother to support later hardware because we have no software that uses it, because there are no drivers, because....?

Where did you hear about this? It's not even listed on AMD's own open-GPU documentation page. This documentation is nice, but I'm still missing the documentation describing how to use the R600 series command processor. Likewise, this document is missing that information, which is something that is needed before it can be used.

I'm still waiting for documentation about the R600 command processor.

EDIT: It's good news though, and I downloaded the documentation. However, I haven't seen a PCI version, so I can't plug one into my A1-XE. I'm going to stick to R500 and R600 support for now.

@rigo

I didn't write that ...... I've just pointed out that lack of demanding apps/games is not really related to missing drivers for higher specced GFX-cards.

There will be demand for drivers at a time when the currently supported Radeons are out of stock, but honestly getting a Voodoo3 for a PCI-busboard is no big deal even today (and these cards are reaaaaaaly old), so we should have a while to concentrate on other things. Like fully supporting all features availbale in currently supported HW.

@Kronos

If we had (full) drivers for the latest graphics cards, then I'd be using the extra features that they have. Not being able to use shaders is preventing any developer from using them. Anyone who is too short-sighted to see the potential use of such drivers is welcome to stick to Radeon 9000 series cards.

Just to be clear, I'm not an OS4 developer, and I don't work on the drivers for older cards. The RadeonHD driver is a personal project of mine. Whilst I would like to see support for existing cards improve, that's not my job. Moreover, waiting until older cards are unavailable before starting to support newer ones is a really stupid strategy.
