          Priority: medium
            Bug ID: 57241
          Assignee: dri-devel@lists.freedesktop.org
           Summary: [r600g] glXCreateContextAttribsARB() fails under
                    certain circumstances
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: nfxjfg@gmail.com
          Hardware: Other
            Status: NEW
           Version: 9.0
         Component: Drivers/DRI/Radeon
           Product: Mesa

Test program: http://sprunge.us/eGJa
Failing output: http://bpaste.net/show/58701/
Successfull output (on another setup): http://dpaste.com/832706/

What seems to trigger this is calling glXCreateContextAttribsARB() with the
following context attributes included: GLX_CONTEXT_PROFILE_MASK_ARB,
GLX_CONTEXT_CORE_PROFILE_BIT_ARB, and GLX_CONTEXT_FLAGS_ARB,
GLX_CONTEXT_FORWARD_COMPATIBLE_BIT_ARB. Removing these seems to make it work.

The test program has been confirmed to work on Mesa with i965, and nvidia
binary drivers 304.60. The actual program which triggered this also works on
fglrx.

User's glxinfo: http://bpaste.net/show/58678/
X server: "x11-base/xorg-server-1.13.0-r1" on Gentoo
The test program is a modified version of
http://www.opengl.org/wiki/Tutorial:_OpenGL_3.0_Context_Creation_(GLX)

It's not clear whether this is a bug or just a caveat, and it has been
confirmed on one installation only so far.

--- Comment #1 from nfxjfg@gmail.com ---
What triggers the failure is indeed GLX_CONTEXT_FORWARD_COMPATIBLE_BIT_ARB. As
far as I know, for drivers which can't handle anything beyond 3.0 or so, this
should be a no-op.

GLX_CONTEXT_CORE_PROFILE_BIT_ARB is ignored (as it should should be with GL
3.0).

Please attach files here directly instead of referencing external sites.

This is probably an issue in a Gallium state tracker, not in the driver;
reassigning.
