Phoronix: More GL3 Work Lands In Mesa

Sweet. We're getting down there...

According to mesa/docs/GL3.txt, we've still got:
GLSL 1.30 (GL_EXT_gpu_shader4, etc.) started
Non-normalized Integer texture/framebuffer formats ~50% done
sRGB framebuffer format (GL_EXT_framebuffer_sRGB) core GL done (i965, gallium), GLX todo
glVertexAttribI commands DONE (but converts int
values to floats)
Depth format cube textures not started
GLX_ARB_create_context (GLX 1.4 is required) not started

I'm pretty sure that this list is out of date, as I thought that GLSL 1.3 was completed, and obviously the GLX_ARB_create_context part has been started (and possibly completed... I haven't tested it myself).

The only thing that concerns me is that I'll have to wait for r600g to catch up to Intel as far as driver-specific support (there's a few parts that have only been implemented for specific chip families according to this document). Even if only Intel is at GL 3.0, that's a huge step forward for Mesa, and should allow the gallium drivers to catch up in a shorter amount of time.

Yep, GL3.txt is outdated, see: http://lists.freedesktop.org/archive...er/016434.html

Currently Mesa from Git breaks OpenGL support in Wine, none of games work. Oddly enough, native Linux games like Nexuiz or OpenArena have no problems, hence looks like this is a bug in Wine rather than in Mesa.

Be sure to file a bug, preferably with a bisect if you know how.

Can you please try starting wine with "WINEDEBUG=+all wine some_windows_binary.exe &> debugoutput.txt"? I have the same problem with wine not working with mesa git, but with WINEDEBUG=+all (piped to a file maybe), it works, but very slow of course. But when the output of WINEDEBUG=+all is piped to /dev/null it does not work anymore...?

Is this just some work on the context creation, or is the implementation done? I will check it out when it's done.

Git bisect probably isn't needed because it's not a commit that causes this, Wine's opengl32.dll just isn't compatible with current Mesa git. Anyway, filed a bug report:

http://bugs.winehq.org/show_bug.cgi?id=29527

They suggest recompiling Wine.

No, this doesn't work for me. If I install an earlier version of Mesa from Archlinux radeon repo, everything works fine.

Turns out that libxcb 1.8 is needed for Wine to work with Mesa 7.12-devel as of now. After updating it, everything works fine.
