At image creation create a path for dealing with the linear modifier. This works exactly like the old usage flags where __DRI_IMAGE_USE_LINEAR was specified. During development of this patch series, it was decided that a lack of modifier was an insufficient way to express the required modifiers. As a result, 0 was repurposed to mean a modifier for a LINEAR layout. NOTE: This patch was added for v3 of the patch series. v2: Rework the algorithm for modifier selection to go from a bitmask based selection to this priority value. v3: Make DRM_FORMAT_MOD_INVALID allowed at selection as a way of identifying no modifiers found (because 0 is LINEAR) (Jason) v4: Remove the logic to prune unknown modifiers (like those from other vendors) and simply handle is in select_best_modifier (Jason) Requested-by: Jason Ekstrand <jason@jlekstrand.net> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Jason Ekstrand <jason@jlekstrand.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.
