AMD Releases Open-Source R600/700 3D Code

[TechMage89]

I bet you think the moon landing was a hoax, too...

Honestly I'm a bit tired of this, it borders on trolling.

You'll likely never see those registers. The powers that control AMD have already decided to stonewall the opensource movement.. probably led by a dominant faction controlling microsoft.

linux will never see 3d opensourced.. just ain't gonna happen.

Both r600_demo and radeonhd include a header file containing all of the register names, offsets, field names, shift and mask info from the register spec document. If you're having trouble sleeping you can take a look at :

http://cgit.freedesktop.org/mesa/r60...eg_auto_r6xx.h

Register info and sample code using the registers is already out. The only additional information in the register spec document is comment information with tips & guidelines for the fields. I didn't feel we had enough review coverage on that part of the package so pulled it out for now to avoid holding up the rest of the information.

> There hasn't been much interest in XvMC so far

Perhaps you missed Phoronix's "2008 Linux Graphics Survey"?

The #1 activity was video playback, listed by 37.90%

"the second area with the most interest is seeing video improvements to X.Org"
Chart says 21.26%

Video playback/acceleration was listed by 15.09%

"When it comes to video playback improvements, the leading open-source solution
right now is through XvMC"

A related feature, TV-out was listed by 19.6%

Does the date 2009-02-17 mean anything to you? Do you actually think that
not many people watch TV?

So there is need/interest. When will FLOSS drivers accelerate mpeg decoding
on AMD/ATI GPUs?

Bridgman is probably talking about developer interest, not general interest. We may not like it, but unless someone with the technical knowhow becomes motivated, neither XvMC not tv-out will see the light of day. That's the way the open-source world works.

What's so signifcant about 2009-02-17?

I started a new thread to get the XvMC discussion out of the r6xx/7xx thread :

BlackStar, Feb 17/09 is the cutover date from analog to digital broadcasting in the U.S., ie the date your analog TV stops working unless you have a set-top box to convert digital broadcasts to analog. Other countries have different cutover dates.

Indeed...
Bravo to AMD and Intel.

Thanks AMD/ATI. And especially thanks to bridgman for your documentation work and involvement on the Phoronix forums.

As I will most likely be auto compiling radeonhd daily where should I send my driver experiences (bug reports) to or who will be working on the R600 (HD 3850) driver?

I was wondering, if it would be possible to make GPU load monitor for Gnome/KDE just like there is for the CPU?

Or can such a thing not be made for a GPU?

[EmbraceUnity]

Great Work! I have already started spreading the good word about your cards. My next card will definitely be from AMD again.

I am so excited now with this documentation drop and the recent Gallium3D developments. We're almost there!

Would all this allow open source GPGPU? Your recent cards are such beasts it seems a shame to let them go to waste for even a second.

In the past we have talked about CAT, KGrids, and TCore, which are all internal ATI/AMD software projects used by their driver developers, but these are no longer being open-sourced.

now i finally understand what does "imminent" mean in phoronix-slang ;-)

aside from that - more great news for ati+linux users.
