[Mesa-dev] Depthbuffer gl_FragDepth / glReadPixels on VMWare
Hi,
i'm trying to get one of our testsuites running in VMWare
(VMware, Inc. Gallium 0.3 on SVGA3D; build: RELEASE; OGL 2.1 Mesa
7.7.1-DEVEL).
With the GDI backend everything works fine (tested in 7.7,7.8,7.10).
I have a glsl shader that writes depth like
void main()
{
vec4 v = texure2D(tex,gl_TexCoord[0].st);
gl_FragColor = vec4(0,0,0,0);
gl_FragDepth = v.x;
}
which doesn't work when running in VMWare's Mesa.
Even a simple clear and readback of the depth buffer doesn't work, like:
glClearDepth(0.6f);
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glReadPixels(0,0,m_Dim[0], m_Dim[1], GL_DEPTH_STENCIL_EXT,
GL_UNSIGNED_INT_24_8_EXT, tmpBufferInt);
or
glReadPixels(0,0,m_Dim[0], m_Dim[1], GL_DEPTH_COMPONENT, GL_FLOAT,
tmpBuffer);
Both reads return all zeros.
I don't know if VMWare's Mesa is a different branch and if this is the right
place to report those bugs (if it is a bug)

I don't know cmake well enough to do that, and I keep forgetting to ask Chad. I have done just that with cmake recently; that is, building an executable twice, once using GL and again with GLES2. When Monday arrives, I'll take a look at how to best coerce Piglit to do this. It looks you already know a better way, but just in case, a straightforward way to do this is using out-of-source builds, one runs configures cmake with two seperate build directories (e.g., build/gl, build/gles) enabling GLES on the latter, and then its simply a matter of doing make -C build/gl make -C build/gles Jose ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev

Re: [Mesa-dev] [PATCH] util: require debug options to be separated by commas

Previously, if we only specified the longer one as a debug option, the shorter one would be considered specified as well (because of strstr). This commit fixes it by checking that each option is surrounded by commas. (a regexp would be nicer, but this is not a performance critical code) Looks good to me. -Brian ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
