Mesa source code tree overview

+ +

+This is a brief summary of Mesa's directory tree and what's contained in +each directory. +

+ + +

docs - Documentation +
include - Public OpenGL header files +
src +
- egl - EGL library sources +
  - docs - EGL documentation +
  - drivers - EGL drivers +
  - main - main EGL library implementation. This is where all + the EGL API functions are implemented, like eglCreateContext(). +
  +
- mesa - Main Mesa sources +
  - glapi - OpenGL API dispatch layer. This is where all the + GL entrypoints like glClear, glBegin, etc. are generated, as well as + the GL dispatch table. All GL function calls jump through the + dispatch table to functions found in main/. +
  - main - The core Mesa code (mainly state management) +
  - drivers - Mesa drivers (not used with Gallium) +
    - common - code which may be shared by all drivers +
    - dri - Direct Rendering Infrastructure drivers +
      - common - code shared by all DRI drivers +
      - i915 - driver for Intel i915/i945 +
      - i965 - driver for Intel i965 +
      - XXX more +
      +
    - x11 - Xlib-based software driver +
    - osmesa - off-screen software driver +
    - glslcompiler - a stand-alone GLSL compiler driver +
    - XXX more +
    +
  - es - OpenGL ES overlay, parallelly buildable with the core Mesa +
  - math - vertex array translation and transformation code + (not used with Gallium) +
  - ppc - Assembly code/optimizations for PPC systems + (not used with Gallium) +
  - shader - Vertex/fragment shader and GLSL compiler code +
  - sparc - Assembly code/optimizations for SPARC systems + (not used with Gallium) +
  - state_tracker - State tracker / driver for Gallium. This + is basically a Mesa device driver that speaks to Gallium. This + directory may be moved to src/mesa/drivers/gallium at some point. +
  - swrast - Software rasterization module. For drawing points, + lines, triangles, bitmaps, images, etc. in software. + (not used with Gallium) +
  - swrast_setup - Software primitive setup. Does things like + polygon culling, glPolygonMode, polygon offset, etc. + (not used with Gallium) +
  - tnl - Software vertex Transformation 'n Lighting. + (not used with Gallium) +
  - tnl_dd - TNL code for device drivers. + (not used with Gallium) +
  - vbo - Vertex Buffer Object code. All drawing with + glBegin/glEnd, glDrawArrays, display lists, etc. goes through this + module. The results is a well-defined set of vertex arrays which + are passed to the device driver (or tnl module) for rendering. +
  - vf - vertex format conversion (currently unused) +
  - x86 - Assembly code/optimizations for 32-bit x86 systems + (not used with Gallium) +
  - x86-64 - Assembly code/optimizations for 64-bit x86 systems + (not used with Gallium) +
  +
- gallium - Gallium3D source code +
  - include - Gallium3D header files which define the Gallium3D + interfaces +
  - drivers - Gallium3D device drivers +
    - cell - Driver for Cell processor. +
    - i915 - Driver for Intel i915/i945. +
    - i965 - Driver for Intel i965. +
    - llvmpipe - Software driver using LLVM for runtime code generation. +
    - nv* - Drivers for NVIDIA GPUs. +
    - r300 - Driver for ATI/AMD R300. +
    - softpipe - Software reference driver. +
    - svga - Driver for VMware's SVGA virtual GPU. +
    - trace - Driver for tracing Gallium calls. +
    - XXX more +
    +
  - auxiliary - Gallium support code +
    - draw - Software vertex processing and primitive assembly + module. This includes vertex program execution, clipping, culling + and optional stages for drawing wide lines, stippled lines, + polygon stippling, two-sided lighting, etc. + Intended for use by drivers for hardware that does not have + vertex shaders. + Geometry shaders will also be implemented in this module. +
    - cso_cache - Constant State Objects Cache. Used to filter out + redundant state changes between state trackers and drivers. +
    - gallivm - LLVM module for Gallium. For LLVM-based + compilation, optimization and code generation for TGSI shaders. + Incomplete. +
    - pipebuffer - utility module for managing buffers +
    - rbug - Gallium remote debug utility +
    - rtasm - run-time assembly/machine code generation. + Currently there's run-time code generation for x86/SSE, PowerPC + and Cell SPU. +
    - tgsi - TG Shader Infrastructure. Code for encoding, + manipulating and interpretting GPU programs. +
    - translate - module for translating vertex data from one format + to another. +
    - util - assorted utilities for arithmetic, hashing, surface + creation, memory management, 2D blitting, simple rendering, etc. +
