This is where all 27 the EGL API functions are implemented, like eglCreateContext(). 28 </ul> 29 <li><b>mesa</b> - Main Mesa sources 30 <ul> 31 <li><b>glapi</b> - OpenGL API dispatch layer. This is where all the 32 GL entrypoints like glClear, glBegin, etc. are generated, as well as 33 the GL dispatch table. All GL function calls jump through the 34 dispatch table to functions found in main/. 35 <li><b>main</b> - The core Mesa code (mainly state management) 36 <li><b>drivers</b> - Mesa drivers (not used with Gallium) 37 <ul> 38 <li><b>common</b> - code which may be shared by all drivers 39 <li><b>dri</b> - Direct Rendering Infrastructure drivers 40 <ul> 41 <li><b>common</b> - code shared by all DRI drivers 42 <li><b>i915</b> - driver for Intel i915/i945 43 <li><b>i965</b> - driver for Intel i965 44 <li>XXX more 45 </ul> 46 <li><b>x11</b> - Xlib-based software driver 47 <li><b>osmesa</b> - off-screen software driver 48 <li><b>glslcompiler</b> - a stand-alone GLSL compiler driver 49 <li>XXX more 50 </ul> 51 <li><b>es</b> - OpenGL ES overlay, parallelly buildable with the core Mesa 52 <li><b>math</b> - vertex array translation and transformation code 53 (not used with Gallium) 54 <li><b>ppc</b> - Assembly code/optimizations for PPC systems 55 (not used with Gallium) 56 <li><b>shader</b> - Vertex/fragment shader and GLSL compiler code 57 <li><b>sparc</b> - Assembly code/optimizations for SPARC systems 58 (not used with Gallium) 59 <li><b>state_tracker</b> - State tracker / driver for Gallium. This 60 is basically a Mesa device driver that speaks to Gallium. This 61 directory may be moved to src/mesa/drivers/gallium at some point. 62 <li><b>swrast</b> - Software rasterization module. For drawing points, 63 lines, triangles, bitmaps, images, etc. in software. 64 (not used with Gallium) 65 <li><b>swrast_setup</b> - Software primitive setup. Does things like 66 polygon culling, glPolygonMode, polygon offset, etc. 67 (not used with Gallium) 68 <li><b>tnl</b> - Software vertex Transformation 'n Lighting. 69 (not used with Gallium) 70 <li><b>tnl_dd</b> - TNL code for device drivers. 71 (not used with Gallium) 72 <li><b>vbo</b> - Vertex Buffer Object code. All drawing with 73 glBegin/glEnd, glDrawArrays, display lists, etc. goes through this 74 module. The results is a well-defined set of vertex arrays which 75 are passed to the device driver (or tnl module) for rendering. 76 <li><b>vf</b> - vertex format conversion (currently unused) 77 <li><b>x86</b> - Assembly code/optimizations for 32-bit x86 systems 78 (not used with Gallium) 79 <li><b>x86-64</b> - Assembly code/optimizations for 64-bit x86 systems 80 (not used with Gallium) 81 </ul> 82 <li><b>gallium</b> - Gallium3D source code 83 <ul> 84 <li><b>include</b> - Gallium3D header files which define the Gallium3D 85 interfaces 86 <li><b>drivers</b> - Gallium3D device drivers 87 <ul> 88 <li><b>cell</b> - Driver for Cell processor. 89 <li><b>i915</b> - Driver for Intel i915/i945. 90 <li><b>i965</b> - Driver for Intel i965. 91 <li><b>llvmpipe</b> - Software driver using LLVM for runtime code generation. 92 <li><b>nv*</b> - Drivers for NVIDIA GPUs. 93 <li><b>r300</b> - Driver for ATI/AMD R300. 94 <li><b>softpipe</b> - Software reference driver. 95 <li><b>svga</b> - Driver for VMware's SVGA virtual GPU. 96 <li><b>trace</b> - Driver for tracing Gallium calls. 97 <li>XXX more 98 </ul> 99 <li><b>auxiliary</b> - Gallium support code 100 <ul> 101 <li><b>draw</b> - Software vertex processing and primitive assembly 102 module. This includes vertex program execution, clipping, culling 103 and optional stages for drawing wide lines, stippled lines, 104 polygon stippling, two-sided lighting, etc. 105 Intended for use by drivers for hardware that does not have 106 vertex shaders. 107 Geometry shaders will also be implemented in this module. 108 <li><b>cso_cache</b> - Constant State Objects Cache.
