Created attachment 124485 [details]
glxinfo output

According to docs/GL3.txt radeonsi should support OpenGL 4.3, but on my hardware (PITCAIRN which is OpenGl 4.5 capable) it does not even though I have LLVM and mesa latest git. According to glxinfo output (see attachment) I do not have ARB_compute_shader for whatever reason. Any clue why ?
BTW: When running with fglrx I have OpenGL 4.5 as expected.

What kernel version are you using?

You need a recent rc version of linux 4.7 for compute shader support on SI.

That would explain it as I'm running 4.6.2. Thank you.
