r600g: closer to running Unigine Heaven?

[kbios]

Today I tried Unigine Heaven (2.0 and 2.5) with the latest opensource stack (r600g), and I was happy to find out that the list of missing extensions is now reduced to:
GL_ARB_map_buffer_range
GL_ARB_vertex_array_object
GL_ARB_half_float_vertex
GL_ARB_half_float_pixel
GL_EXT_texture_swizzle
GL_ARB_framebuffer_object
GL_EXT_framebuffer_blit
GL_EXT_framebuffer_multisample
2.5 complained also that it couldn't get 4 buffers (mesa limitation?), while with 2.0 forcing them with MESA_EXTENSION_OVERRIDE allowed the demo to start, but it crashed after displaying a black window. Nevertheless, it's getting there.

I just ran version 2.5 with current drm-next kernel and mesa, libdrm and xf86-vide-ati from git master. It seems to find everything that it needs. It doesn't show a picture though (only black but the menu was shown and a framerate of 20fps) and it floods the console with:

GLFrameBuffer::enable(): incomplete attachment
OpenGL error: invalid framebuffer operation

At start it showed following summary:

That's impressive. Are you using the floating branch? That would probably explain the different extensions. Also my tests were done on an HD4200, so this may be the reason why it says that there is no support for 4 buffers?
Thanks

[droste]

No I'm using master. Maybe it's a kernel difference or because my card is an evergreen.

But there's a bug in the demo (version 2.5): It checks for GL_ARB_draw_instanced but actually uses GL_EXT_draw_instanced or a mix of both. This seems to work with nvidia blobs but it's wrong.
Nevertheless even if the check would be right, there's a different problems with mesa drivers. They claim to support GL_EXT_draw_instanced, but they don't and if you're trying to use it, you're getting in trouble.

All the extensions you mention are fully supported by r600g. You are simply not running the driver. (or you are missing the 32-bit driver if Unigine Heaven is a 32-bit application)

[Kano]

Just dl heaven and you will see that it has 32+64 bit versions included.

[kbios]

Indeed, a *##* update reverted the system to r600c. With actual r600g, the intro splash screen appears and loads, but at the end of the loading it crashes with

Heaven_x64: program/ir_to_mesa.cpp:2281: prog_src_register mesa_src_reg_from_ir_src_reg(ir_to_mesa_src_reg): Assertion `reg.index < (1 << 11)' failed.

Unigine sanctuary is almost there too, ofc still fails to render so i include the full output of the run so maybe is helpful for anyone

That's weird, it works here (apart from S3TC -> Black textures).

[Welsh Dwarf]

If by black textures, you mean no wireframe either, then I'm in the same case.

But it isn't S3TC related, since I had mesa nightly and ENABLE_S3TC=1
