System Environment:
--------------------------
machines: piketon, G45
Libdrm:		(master)a3305b076c005e0d3bd55da0214e91413cf65b48

Bug detailed description:
-------------------------
Glean case api2/shaderAPI and 30 piglit case (glslparsertest_TextureRectangleSamplers.frag, glslparsertest_glsl2_gst-gl-bulge.frag, glslparsertest_glsl2_gst-gl-glass.frag, ...) failed for adding parameter "--enable-gles2" on MESA build.  This issue only happens on mesa master branch. It works well if no "--enable-gles2". 

Reproduce steps:
--------------------
1../autogen.sh --prefix=$INSTALL_ROOT --with-driver=dri --with-dri-  drivers="i965" --with-dri-driverdir=$INSTALL_ROOT/lib/dri --disable-gallium --without-demos --disable-glw --disable-gallium-intel --enable-gles2
2.make and make install
3.run glean and piglit case
Comment 1 fangxun 2010-05-23 23:10:41 UTC 
This issue also happens on pineview. It make glean case(pbo,texgen,vertProg1) and many piglit case(bugs_fdo22540,bugs_fdo25614-genmipmap,fbo_fbo-1d,fbo_fbo-3d,fbo_fbo-blit,fbo_fbo-copypix,fbo_fbo-copyteximage,...)faied. These failed case is different to failed case on G45. 

It also causes 3D games(openarena, ut2004) black screen on pineview. With black screen, The performance is improved 168%, from 19 to 51. 
3D games works well on G45.

Should be fixed by:

    mesa: Handle FEATURE_es2_glsl differences at runtime too
    
    Now that we can support different APIs at runtime, we need to check the
    context for the API we're currently providing as well.
