            Bug ID: 91802
           Summary: Cannot get OpenGL 4.1 context on AMD 6750M
           Product: Mesa
           Version: 10.6
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org

This is a followup to bug https://github.com/Polytonic/Glitter/issues/8 , where
I (an OpenGL newcomer) am trying to run a boilerplate OpenGL project.

The code I'm building lives at
https://github.com/Polytonic/Glitter/blob/master/Glitter/Sources/main.cpp , and
what happens is that the glfwCreateWindow call at line 21 returns nullptr with
a 4.1 context, but works under 3.3.

I'm clueless here, but the maintainer of the project says he owned the same
hardware, knows 4.1 should be supported, and I should file a bug, so here it

OS: Linux x 4.1.6-1-ARCH #1 SMP PREEMPT x86_64
GPU: [AMD/ATI] Madison [Mobility Radeon HD 5730 / 6570M]
Software (all from the Arch repos): xf86-video-ati 7.5.0-2, mesa-libgl
10.6.5-1, mesa-vdpau 10.6.5-1

Feel free to ask for more info if this sounds like a real bug, and sorry if I
miscategorized (I know I'm using Gallium, but am unsure what driver my 6570M
uses; it's before r200, is it 'radeonsi'? Not sure :-/ ). Thanks for your help.
