Currently the logic allocating and setting up miptrees is closely
combined with decision making when to re-allocate buffers in
X-tiled layout and when to associate colors with auxiliary buffers.
These auxiliary buffers are in turn also represented as miptrees
and are created by the same miptree creation logic calling itself
recursively. This means considering in vain if the auxiliary buffers
should be represented in X-tiled layout or if they should be
associated with auxiliary buffers again.
While this is somewhat unnecessary, this doesn't impose any problems
currently. Miptrees for auxiliary buffers are created as simgle-sampled
fusing the consideration for multi-sampled compression auxiliary
buffers. The format in turn is such that is not applicable for
single-sampled fast clears (that would require accompaning auxiliary
buffer).
But once the driver starts to support lossless compression of color
buffers the auxiliary buffer will have a format that would itself
be applicable for lossless compression. This would be rather
difficult and ugly to detect in the current miptree creation logic,
and therefore this patch seeks to separate the association logic
from the general allocation and setup steps.
v2 (Ben):
- Do not reconsider for X-tiling in intel_miptree_create()
as it was just forced to Y-tiling in miptree_create().
- Do not drop checks for allocation failures.

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.
