-<H1>Environment Variables</H1>
-
-<p>
-Normally, no environment variables need to be set. Most of the environment
-variables used by Mesa/Gallium are for debugging purposes, but they can
-sometimes be useful for debugging end-user issues.
-</p>
-
-
-<H2>LibGL environment variables</H2>
-
-<ul>
-<li>LIBGL_DEBUG - If defined debug information will be printed to stderr.
- If set to 'verbose' additional information will be printed.
-<li>LIBGL_DRIVERS_PATH - colon-separated list of paths to search for DRI drivers
-<li>LIBGL_ALWAYS_INDIRECT - forces an indirect rendering context/connection.
-<li>LIBGL_ALWAYS_SOFTWARE - if set, always use software rendering
-<li>LIBGL_NO_DRAWARRAYS - if set do not use DrawArrays GLX protocol (for debugging)
-</ul>
-
-
-
-<H2>Core Mesa environment variables</H2>
-
-<ul>
-<li>MESA_NO_ASM - if set, disables all assembly language optimizations
-<li>MESA_NO_MMX - if set, disables Intel MMX optimizations
-<li>MESA_NO_3DNOW - if set, disables AMD 3DNow! optimizations
-<li>MESA_NO_SSE - if set, disables Intel SSE optimizations
-<li>MESA_DEBUG - if set, error messages are printed to stderr. For example,
- if the application generates a GL_INVALID_ENUM error, a corresponding error
- message indicating where the error occured, and possibly why, will be
- printed to stderr.<br>
- If the value of MESA_DEBUG is 'FP' floating point arithmetic errors will
- generate exceptions.
-<li>MESA_TEX_PROG - if set, implement conventional texture env modes with
-fragment programs (intended for developers only)
-<li>MESA_TNL_PROG - if set, implement conventional vertex transformation
-operations with vertex programs (intended for developers only).
-Setting this variable automatically sets the MESA_TEX_PROG variable as well.
-<li>MESA_EXTENSION_OVERRIDE - can be used to enable/disable extensions.
-A value such as "GL_EXT_foo -GL_EXT_bar" will enable the GL_EXT_foo extension
-and disable the GL_EXT_bar extension.
-<li>MESA_GLSL - <a href="shading.html#envvars">shading language compiler options</a>
-</ul>
-
-
-<H2>Mesa Xlib driver environment variables</H2>
-
-<p>
-The following are only applicable to the Mesa Xlib software driver.
-See the <A HREF="xlibdriver.html">Xlib software driver page</A> for details.
-</p>
-<ul>
-<li>MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode
-<li>MESA_CI_VISUAL - specifies the X visual and depth for CI mode
-<li>MESA_BACK_BUFFER - specifies how to implement the back color buffer,
- either "pixmap" or "ximage"
-<li>MESA_GAMMA - gamma correction coefficients for red, green, blue channels
-<li>MESA_XSYNC - enable synchronous X behavior (for debugging only)
-<li>MESA_GLX_FORCE_CI - if set, force GLX to treat 8bpp visuals as CI visuals
-<li>MESA_GLX_FX - set to either "fullscreen" for full-screen rendering,
- "window" to render into a window, or "disable" to disable the Glide driver.
-<li>MESA_GLX_FORCE_ALPHA - if set, forces RGB windows to have an alpha channel.
-<li>MESA_GLX_DEPTH_BITS - specifies default number of bits for depth buffer.
-<li>MESA_GLX_ALPHA_BITS - specifies default number of bits for alpha channel.
-</ul>
-
-
-<h2>i945/i965 driver environment variables (non-Gallium)</h2>
-
-<ul>
-<li>INTEL_STRICT_CONFORMANCE - if set to 1, enable sw fallbacks to improve
- OpenGL conformance. If set to 2, always use software rendering.
-<li>INTEL_NO_BLIT - if set, disable hardware-accelerated glBitmap,
- glCopyPixels, glDrawPixels.
-</ul>
-
-
-<h2>Radeon R300 driver environment variables (non-Gallium)</h2>
-
-<ul>
-<li>R300_NO_TCL - if set, disable hardware-accelerated Transform/Clip/Lighting.
-</ul>
-
-
-<h2>EGL environment variables</h2>
-
-<p>
-Mesa EGL supports different sets of environment variables. See the
-<a href="egl.html">Mesa EGL</a> page for the details.
-</p>
-
-
-<h2>Gallium environment variables</h2>
-
-<ul>
-<li>GALLIUM_PRINT_OPTIONS - if non-zero, print all the Gallium environment
- variables which are used, and their current values.
-<li>GALLIUM_NOSSE - if non-zero, do not use SSE runtime code generation for
- shader execution
-<li>GALLIUM_NOPPC - if non-zero, do not use PPC runtime code generation for
- shader execution
-<li>GALLIUM_DUMP_CPU - if non-zero, print information about the CPU on start-up
-<li>TGSI_PRINT_SANITY - if set, do extra sanity checking on TGSI shaders and
- print any errors to stderr.
-<LI>DRAW_FSE - ???
-<LI>DRAW_NO_FSE - ???
-<li>DRAW_USE_LLVM - if set to zero, the draw module will not use LLVM to execute
- shaders, vertex fetch, etc.
-</ul>
-
-<h3>Softpipe driver environment variables</h3>
-<ul>
-<li>SOFTPIPE_DUMP_FS - if set, the softpipe driver will print fragment shaders
- to stderr
-<li>SOFTPIPE_DUMP_GS - if set, the softpipe driver will print geometry shaders
- to stderr
-<li>SOFTPIPE_NO_RAST - if set, rasterization is no-op'd. For profiling purposes.
-</ul>
-
-
-<h3>LLVMpipe driver environment variables</h3>
-<ul>
-<li>LP_NO_RAST - if set LLVMpipe will no-op rasterization
-<li>LP_DEBUG - a comma-separated list of debug options is acceptec. See the
- source code for details.
-<li>LP_PERF - a comma-separated list of options to selectively no-op various
- parts of the driver. See the source code for details.
-<li>LP_NUM_THREADS - an integer indicating how many threads to use for rendering.
- Zero turns of threading completely. The default value is the number of CPU
- cores present.
-</ul>
-
-
-<p>
-Other Gallium drivers have their own environment variables. These may change
-frequently so the source code should be consulted for details.
