Re: [Mesa-dev] GL 3.1 on Radeon HD 4670?

There isn't one, but it's something that we talked about doing. I guess nobody got the motivation to do it. That may partially be because we weren't sure how we wanted it to operate. glxinfo already dumps quite a pile of info. Should we make it dump information for both core and compatibility? What about ES? etc. Thanks for making all of this open source and possible too; I probably have one of the only ia64 systems with GL = 3.0 in the world!

DOH. I'm sorry, I read that Mesa supported GL 3.1 and somehow I generalized that to all drivers. Thanks for that TODO list. I guess I need to start reading about the R700 architecture...

The open source r600g driver only supports GL 3.0 at the moment.

The missing features for GL 3.1 are just UBOs and TBOs. Dave Airlie has been working on TBOs. Nobody is working on UBOs as far as I know. Both features need changes in the driver and in the common code (st/mesa). Marek On Wed, Oct 31, 2012 at 7:34 PM, Patrick Baggett baggett.patr...@gmail.com wrote: DOH.

I should probably push the state tracker tbo bits, they were fairly trivial, and I don't think the ubo bits are insanely hard either, also we need to check is there any reason we can't advertise GLSL 1.40.
