AMD R600g Is Making Progress With Tessellation, Running Heaven

[PuckPoltergeist]

It doesn't work like that. Mesa/Radeon is a developing framework trying to catch up with existing applications and mimicing what proprietary code has been doing for years. Programs using Opengl already exist and the requirements are already written. What Mesa can do is fulfilling them, or fooling the program to believe in this. Or stay behind. Programs won't be patched.

This can change in the future, when developers accept it and officially support it. This is very rarely the case in the present and won't change in the near future.

You HAVE TO give a talk on next XDC, so Dave (and the other developers) can learn from you...

I was expecting success soon so this wasn't an to big surprise since i followed davids git and seen the changes in mesa to prepare for tesselation on r600.
Thanks David for your work on bringing tesselation to EG/NI it feels good knowing it's a bit closer.

When entering "HD 6870" in http://mesamatrix.net/drivers.php, I get "Your GPU family is: Northern Islands", so it means I'll have OpenGL 4.1 sooner than later, right? (If not, could you explain why so that I can fix a bug in this feature if there is one).

Anyway, thanks a lot David for this awesome work, I'm eager to see this tiny red box disappear in Mesamatrix

This has been gone over a lot of times before.

You don't want to fall back to CPU emulation for fp64 support, when the GPUs can do it themselves. (Not natively, but the GPU can use f32 instructions to emulate f64 instructions - that's much faster than doing it on the CPU, and dragging everything else related to that shader also to be on the CPU just because it had a 64bit instruction in it at one place)

Oh, I get it now. Hopefully this will happen sooner than later

Thanks people for being patient and replying, and thank you very much David and the rest of the Radeon/Mesa team for your hard work!

Some cards need to emulate f64 instructions because they don't support it natively. (or something like that) Someone has to write this code. And AFAI understand its not high priority. I trully hope someone writes it. *crosses fingers

Let's hope someone codes the fp64 instructions emulation, especially now that catalyst won't be getting any updates for these cards.

Really hope this can be done. My 6670 (Turks) is plenty powerful to play games such as Dirt Showdown, but without GL 4.1, its not possible w/o catalyst. I'd like to get off of catalyst (especially now, since AMD has depreciated all Radeon 5000/6000 cards) and only the OpenGL 4+ issue is holding me back.

Dirt Showdown is playable on r600g, even developers say that: http://steamcommunity.com/app/201700...25103631806230

You just need this in your start options:
MESA_GL_VERSION_OVERRIDE=4.2 MESA_GLSL_VERSION_OVERRIDE=420 %command%

Great card isn't it? I have the very same one. I keep trying to find a reason to upgrade but can't since the things I do work very well with the 6670. =)

Since so many wonder what hardware will be supported it's a good thing David included this in the patches.
Currently tested hw: working: CAYMAN, REDWOOD, BARTS, TURKS
hangs on any tessellation: CAICOS
hangs differently at least with heaven: SUMO

Currently known broken are SUMO/CAICOS
working are CAYMAN/REDWOOD/BARTS/TURKS.
