The CL CTS queries CL_DEVICE_MEM_BASE_ADDR_ALIGN for a device and
then allocates user pointers aligned to that value for its tests.
The minimum value is defined as:
the size (in bits) of the largest OpenCL built-in data type supported
by the device (long16 in FULL profile, long16 or int16 in EMBEDDED
profile) for devices that are not of type CL_DEVICE_TYPE_CUSTOM.
At the moment, all known devices that support user pointers require
CPU page alignment for buffers created from user pointers, so just
query that from sysconf.
v3: Use std::max instead of MAX2 (Francisco)
Add missing unistd include
v2: Use system page size instead of a new pipe cap

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.
