Environment Variables

-Mesa supports the following environment variables: +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.

LibGL environment variables

    +
  • LIBGL_DEBUG - If defined debug information will be printed to stderr. + If set to 'verbose' additional information will be printed. +
  • LIBGL_DRIVERS_PATH - colon-separated list of paths to search for DRI drivers +
  • LIBGL_ALWAYS_INDIRECT - forces an indirect rendering context/connection. +
  • LIBGL_ALWAYS_SOFTWARE - if set, always use software rendering +
  • LIBGL_NO_DRAWARRAYS - if set do not use DrawArrays GLX protocol (for debugging) +
+ + + +

Core Mesa environment variables

  • MESA_NO_ASM - if set, disables all assembly language optimizations
  • MESA_NO_MMX - if set, disables Intel MMX optimizations
  • MESA_NO_3DNOW - if set, disables AMD 3DNow! optimizations
  • MESA_NO_SSE - if set, disables Intel SSE optimizations -
  • MESA_DEBUG - if set, error messages are printed to stderr. -If the value of MESA_DEBUG is "FP" floating point arithmetic errors will -generate exceptions. -
  • MESA_NO_DITHER - if set, disables dithering, overriding glEnable(GL_DITHER) +
  • 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.
    + If the value of MESA_DEBUG is 'FP' floating point arithmetic errors will + generate exceptions.

  • MESA_TNL_PROG - if set, implement conventional vertex transformation @@ -28,11 +49,14 @@ Setting this variable automatically sets the MESA_TEX_PROG variable as well.
  • 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. -

EGL environment variables

Mesa EGL supports different sets of environment variables. See the Mesa EGL page for the details.

+ +

Gallium environment variables

+ +
    +
  • GALLIUM_PRINT_OPTIONS - if non-zero, print all the Gallium environment + variables which are used, and their current values. +
  • GALLIUM_NOSSE - if non-zero, do not use SSE runtime code generation for + shader execution +
  • GALLIUM_NOPPC - if non-zero, do not use PPC runtime code generation for + shader execution +
  • GALLIUM_DUMP_CPU - if non-zero, print information about the CPU on start-up +
  • TGSI_PRINT_SANITY - if set, do extra sanity checking on TGSI shaders and + print any errors to stderr. +
  • DRAW_FSE - ??? +
  • DRAW_NO_FSE - ??? +
  • DRAW_USE_LLVM - if set to zero, the draw module will not use LLVM to execute + shaders, vertex fetch, etc. +

Softpipe driver environment variables

+
    +
  • SOFTPIPE_DUMP_FS - if set, the softpipe driver will print fragment shaders + to stderr +
  • SOFTPIPE_DUMP_GS - if set, the softpipe driver will print geometry shaders + to stderr +
  • SOFTPIPE_NO_RAST - if set, rasterization is no-op'd. For profiling purposes. +

LLVMpipe driver environment variables

    +
  • LP_NO_RAST - if set LLVMpipe will no-op rasterization +
  • LP_DEBUG - a comma-separated list of debug options is acceptec. See the + source code for details. +
  • LP_PERF - a comma-separated list of options to selectively no-op various + parts of the driver. See the source code for details. +
  • 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. +
+ + +

+Other Gallium drivers have their own environment variables. These may change +frequently so the source code should be consulted for details. +
