Current logic calls intel_renderbuffer_set_draw_offset() which in turn tries to calculate x and y offset against layer/level settings that are against the original miptree actually having sufficient levels/layers. This returns correctly x=0 y=0 regardless of the given layer/level only because one calls intel_miptree_get_image_offset() which goes and consults miptree offset table which in turn luckily contains entries for max-mipmap levels, all initialised to zero even in case of non-mipmapped. This patch stops consulting the table and simply sets the draw offsets to zero that are compatible with the single slice miptree backing the renderbuffer. This prepares for ISL based miptrees that calculate offsets on-demand and do not tolerate levels beyond what the miptree has.

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.
