This introduces a new fast virtual memory allocator integrated with our BO cache bucketing. For larger objects, it falls back to the simple free-list allocator (util_vma). This puts the allocators in place but doesn't enable softpin yet. v2: (feedback from Chris Wilson) - Check (bo->kflags & EXEC_OBJECT_PINNED) instead of a global flag - Avoid vma_free(0ull) on the err_free path. - Only enable if the kernel says we have full PPGTT support - Make bucketing allocators more resistant to failing to grow arrays (feedback from Scott Phillips) - Don't use node after popping it from the list. - Avoid undefined behavior in canonicalization by reusing new helper - Comment updates (feedback from myself) - Avoid __vma_alloc vs. vma_alloc by making a zero_high_bits helper to return a non-canonical address with the high bits zeroed. - Don't shadow loop variable 'i' when destroying things (ugly; worked) v3: - Replace zero_high_bits with new common gen_48b_address helper.

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.
