This file provides a portability layer that will make it easier to convert SSE-based functions to VMX/VSX-based functions. All the functions implemented in this file are prefixed using "vec_". Therefore, when converting from SSE-based function, one needs to simply replace the "_mm_" prefix of the SSE function being called to "vec_". Having said that, not all functions could be converted as such, due to the differences between the architectures. So, when doing such conversion hurt the performance, I preferred to implement a more ad-hoc solution. For example, converting the _mm_shuffle_epi32 needed to be done using ad-hoc masks instead of a generic function. All the functions in this file support both little-endian and big-endian but currently the file is build only on POWER8 LE machine. All of the functions are implemented using the Altivec/VMX intrinsics, except one where I needed to use inline assembly (due to missing intrinsic). v2: - Use vec_vgbbd instead of __builtin_vec_vgbbd - Add an aligned load function - Don't use typeof() - Make file build only on POWER8 LE machine Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Reviewed-by: Roland Scheidegger <sroland@vmware.com>
File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see http://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
