How to enable opengl 3.3 on r9 270?

[peppercats]

Question in the title. Using Ubuntu 14.04 with 3.14 kernel and oibaf PPA(mesa 10.2)

Reading around I should have openGL 3.3, but it's only 3.0? I can't run a lot of benchmarks/games that require later GL versions.

OpenGL 3.1 and higher are only available with the core profile. If you run "glxinfo | grep core" it should give you the highest version available with a core profile.

OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.2.0-devel (git-857f3a6 trusty-oibaf-ppa)

Is this normal? I can't run unigine heaven It works just fine with fglrx

Hm maybe kernel too old? AFAIK radeonsi should be at OGL 3.3.

you could try to run it with MESA_GL_VERSION_OVERRIDE=3.2 and MESA_GLSL_VERSION_OVERRIDE=150 set.

MESA_GL_VERSION_OVERRIDE=3.2 MESA_GLSL_VERSION_OVERRIDE=150 ./heaven

Tried with both kernel 3.14 and 3.13, it's the same on both. HDMI audio doesn't work on 3.14 so I'm back on 3.13...

Trying that just outputs a black screen

Hum, not sure what I did but the override seems to be working now. I wonder why I don't have 3.3 core by default though, the x.org site notes that you need LLVM 3.5 maybe that's it?

[marek]

You need LLVM 3.5, which hasn't been released yet, so you have to compile it manually from git or svn. Then, you have to reconfigure and recompile Mesa. The Mesa ./configure script must print that it found LLVM 3.5.

Fglrx is 50% faster than the open source driver (in unigine heaven, anyways)

Thanks for the help.

is LLVM 3.5 the same as LLVM 3.4.1? if not, does LLVM 3.4.1 help somehow?

[bridgman]

Where are you seeing LLVM 4.1 ? The most recent release is 3.4 and 3.5 is "work in process" :

EDIT -- ahh, I see, you meant 3.4.1... but not sure where you are seeing that either
