             Bug #: 47955
           Summary: Celestia hit fallback on r300g from git?
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: randrik@mail.ru


Hello. 

Using kernel 3.2.9 vanilla (also tried 3.1.0-rc9 + nouveau patches),
libdrm/ddx/mesa from git, and X server 1.10.4 i have strange bug on my rs600:

if i start celestia (self-compiled, version 1.6.1, with gtk2 interface) in its
default rendering mode - it show mostly white window. Selecting another
rendering path, like "basic" or "multitexture" makes it work OK. Witb white
window i have extremely low framerates, like 1.x something fps. Tried
RADEON_DEBUG options , without luck.

Will add logs and screenshot.

Mesa was compiled  with ./configure --prefix=/usr/X11R7 --disable-egl
--enable-gallium-llvm --with-gallium-drivers=i915 nouveau r600 r300 swrast
--enable-texture-float --with-dri-drivers=i965 r200 radeon nouveau
--enable-shared-glapi --enable-gallium-g3dvl --enable-vdpau --enable-debug

Gallium libs - version 2.9. (I tried DRAW_NO_LLVM=1 - bug was still there).
llvmpipe renders Celestia's window correctly in all modes.

If i set "Star style" to "Points" it works OK, another  two options (default
"Fuzzy Points" and "Scaled Disks") produces white slow screen.

as far as I can see in celestia-1.6.1/src/celengine/render.cpp (function void
Renderer::PointStarVertexBuffer::startSprites() ) - it uses some combination of
GL_ARB_point_sprite and vertex shaders .... Any ideas what can fail  with this
combo on rs600 ?


----------------------------

void Renderer::PointStarVertexBuffer::startSprites(const GLContext& _context)
{
    context = &_context;
    assert(context->getVertexProcessor() != NULL || !useSprites); // vertex
shaders required for new star rendering

    unsigned int stride = sizeof(StarVertex);
    glEnableClientState(GL_VERTEX_ARRAY);
    glVertexPointer(3, GL_FLOAT, stride, &vertices[0].position);
    glEnableClientState(GL_COLOR_ARRAY);
    glColorPointer(4, GL_UNSIGNED_BYTE, stride, &vertices[0].color);

    VertexProcessor* vproc = context->getVertexProcessor();
    vproc->enable();
    vproc->use(vp::starDisc);
    vproc->enableAttribArray(6);
    vproc->attribArray(6, 1, GL_FLOAT, stride, &vertices[0].size);

    glDisableClientState(GL_TEXTURE_COORD_ARRAY);
    glDisableClientState(GL_NORMAL_ARRAY);

    glEnable(GL_POINT_SPRITE_ARB);
    glTexEnvi(GL_POINT_SPRITE_ARB, GL_COORD_REPLACE_ARB, GL_TRUE);

    useSprites = true;
}
--------------------------------------------

Any piglit test?

wild guess: r300g need something like  this?

Or
http://cgit.freedesktop.org/mesa/mesa/commit/?id=1a69b50b3b441ce8f7a00af3a7f02c37df50f6c3

Namely calls to

draw_create_fragment_shader() and draw_bind_fragment_shader() , probably they
should go into 300_state.c, r300_{create|bind}_fs_state ?

FWIW, that's not a recognized environment variable. You probably meant
DRAW_USE_LLVM=0.

Yes, sorry. Tried twice with DRAW_USE_LLVM=0 - bug still here. I'll try to
patch driver  with my idea above and see if it will fix  this  bug ...

Unfortunately, it was not as simple as copy/pasting code ... no patch from me
:(

.. and spriteblast mesa demo surely don't work correctly here. (I see something
remotely like _giant_ sprites flashing on screen)

Is this bug present in Mesa 8.0 and if yes, is it present in 7.11 as well?

yes, at minimum in 8.0 and 7.11 git _branches_. With 7.11 it was a bit unstable
- but bug still around, both for celestia and pointblast/spriteblast mesa
demos.

I know. The vertex shader point size output is broken on SWTCL chipsets
(piglit/glsl-vs-point-size fails randomly). I haven't been able to find the
cause yet.
