Previously, we emitted the shader-time epilogue from emit_fb_writes(), during the middle of looping through color regions (or emit_urb_writes for the VS). This is duplicated several times and rather awkward. I need to fix a bug in our FB write handling, and it will be a lot easier if we move emit_shader_time_end() out of there. Now, we simply emit FB writes/URB writes, and subsequently have emit_shader_time_end() insert instructions before the final SEND with EOT. Not only is this simpler, it's actually a slight improvement: we now include the MOVs to set up the final FB write payload in our shader-time measurements. Note that INTEL_DEBUG=shader_time only exists on Gen7+, and uses send-from-GRF. (In the past, we might have hit trouble where both attempt to use MRFs for messages; that's not a problem now.) v2: Rebase on v3 of the previous patch and other shader_time fixes.

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 osmesa to build classic osmesa driver; 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. 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.
