This patch consolidates duplicate code in the brw_depthbuffer and gen7_depthbuffer state atoms. Previously, these state atoms contained 5 chunks of code for emitting the _3DSTATE_DEPTH_BUFFER packet (3 for Gen4-6 and 2 for Gen7). Also a lot of logic for determining the appropriate buffer setup was duplicated between the Gen4-6 and Gen7 functions. This refactor splits the code into three separate functions: brw_emit_depthbuffer(), which determines the appropriate buffer setup in a mostly generation-independent way, brw_emit_depth_stencil_hiz(), which emits the appropriate state packets for Gen4-6, and gen7_emit_depth_stencil_hiz(), which emits the appropriate state packets for Gen7. Tested using Piglit on Gen5-7 (no regressions). v2: Re-word some comments. Fix an assertion that incorrectly prohibited packed depth/stencil formats on Gen6 (these are allowed provided that HiZ is disabled).

File: docs/README.WIN32 Last updated: 23 April 2011 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons osmesa mesagdi to build classic mesa Windows GDI drivers; or 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. 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.
