[Piglit] [PATCH 0/8 v2] Support creation of debug and forward-compatible contexts

[Timothy Arceri]

Here is some feedback from my testing with AMD Catalyst drivers. As
previously discussed they seem to be missing GLX_ARB_create_context
extension is from "server glx extensions"

With V1 on Catalyst I got:

piglit: info: Failed to create GL 1.0 compatibility context
piglit: info: Failed to create any GL context
PIGLIT: {'result': 'skip' }

With this version I'm getting:

piglit: error: waffle_config_choose failed due to
WAFFLE_ERROR_BAD_ATTRIBUTE: unrecognized attribute 0x216 at
attrib_list[6]
piglit: error: Failed to create waffle_config for OpenGL 1.0 Debug
Context
piglit: info: Failed to create any GL context
