We need to split DF instructions in two on IVB/BYT as it needs an execsize 8 to process 4 DF values (one GRF in total). v2: - Rename helper and make it static inline function (Matt). - Fix indention and add braces (Matt). v3: - Don't edit IR instruction when doubling exec_size (Curro) - Add comment into the code (Curro). - Manage ARF registers like the others (Curro) v4: - Add get_exec_type() function and use it to calculate the execution size. Signed-off-by: Samuel Iglesias Gonsálvez <siglesias@igalia.com> [ Francisco Jerez: Fix bogus 'type != BAD_FILE' check. Take destination type as execution type where there is no valid source. Assert-fail if the deduced execution type is byte. Clarify comment in get_lowered_simd_width(). Move SIMD width workaround outside of 'if (...inst->size_written > REG_SIZE)' conditional block, since the problem should be independent of whether the amount of data written by the instruction is greater or lower than a GRF. Drop redundant is_ivb_df definition. Drop bogus inst->exec_size < 8 check. Simplify channel group assertion. ] Reviewed-by: Francisco Jerez <currojerez@riseup.net>
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 https://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.
