-<h1>Mesa source code tree overview</h1>
+<h1>Source Code Tree</h1>
<p>
This is a brief summary of Mesa's directory tree and what's contained in
<li><b>include</b> - Public OpenGL header files
<li><b>src</b>
<ul>
+ <li><b>compiler</b> - Common utility sources for different compilers.
+ <ul>
+ <li><b>glsl</b> - the GLSL IR and compiler
+ <li><b>nir</b> - the NIR IR and compiler
+ <li><b>spirv</b> - the SPIR-V compiler
+ </ul>
<li><b>egl</b> - EGL library sources
<ul>
- <li><b>docs</b> - EGL documentation
<li><b>drivers</b> - EGL drivers
<li><b>main</b> - main EGL library implementation. This is where all
the EGL API functions are implemented, like eglCreateContext().
</ul>
- <li><b>mesa</b> - Main Mesa sources
- <ul>
+ <li><b>mapi</b> - Mesa APIs
<li><b>glapi</b> - 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/.
+ <li><b>mesa</b> - Main Mesa sources
+ <ul>
<li><b>main</b> - The core Mesa code (mainly state management)
<li><b>drivers</b> - Mesa drivers (not used with Gallium)
<ul>
<li><b>common</b> - code shared by all DRI drivers
<li><b>i915</b> - driver for Intel i915/i945
<li><b>i965</b> - driver for Intel i965
+ <li><b>radeon</b> - driver for ATI R100
+ <li><b>r200</b> - driver for ATI R200
<li>XXX more
</ul>
<li><b>x11</b> - Xlib-based software driver
<li><b>osmesa</b> - off-screen software driver
- <li><b>glslcompiler</b> - a stand-alone GLSL compiler driver
<li>XXX more
</ul>
- <li><b>es</b> - OpenGL ES overlay, parallelly buildable with the core Mesa
<li><b>math</b> - vertex array translation and transformation code
(not used with Gallium)
- <li><b>ppc</b> - Assembly code/optimizations for PPC systems
- (not used with Gallium)
- <li><b>shader</b> - Vertex/fragment shader and GLSL compiler code
+ <li><b>program</b> - Vertex/fragment shader and GLSL compiler code
<li><b>sparc</b> - Assembly code/optimizations for SPARC systems
(not used with Gallium)
<li><b>state_tracker</b> - State tracker / driver for Gallium. This
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.
- <li><b>vf</b> - vertex format conversion (currently unused)
<li><b>x86</b> - Assembly code/optimizations for 32-bit x86 systems
(not used with Gallium)

<ul>
- <li><b>cell</b> - Driver for Cell processor.
<li><b>i915</b> - Driver for Intel i915/i945.
- <li><b>i965</b> - Driver for Intel i965.
<li><b>llvmpipe</b> - Software driver using LLVM for runtime code generation.
- <li><b>nv*</b> - Drivers for NVIDIA GPUs.
- <li><b>r300</b> - Driver for ATI/AMD R300.
+ <li><b>nouveau</b> - Driver for NVIDIA GPUs.
+ <li><b>radeon</b> - Shared module for the r600 and radeonsi drivers.
+ <li><b>radeonsi</b> - Driver for AMD Southern Island.
+ <li><b>r300</b> - Driver for ATI R300 - R500.

<li><b>softpipe</b> - Software reference driver.
<li><b>svga</b> - Driver for VMware's SVGA virtual GPU.
<li><b>trace</b> - Driver for tracing Gallium calls.
Currently there's run-time code generation for x86/SSE, PowerPC
and Cell SPU.
<li><b>tgsi</b> - TG Shader Infrastructure. Code for encoding,
- manipulating and interpretting GPU programs.
+ manipulating and interpreting GPU programs.
<li><b>translate</b> - module for translating vertex data from one format
to another.
<li><b>util</b> - assorted utilities for arithmetic, hashing, surface
creation, memory management, 2D blitting, simple rendering, etc.
