HiZ operations make the depth/render caches out of sync with the sampler caches. We need to arrange for a TC flush to happen before the target buffer is used by the sampler. Calling brw_render_cache_set_add_bo makes that happen. On previous generations, brw_blorp_exec took care of flushing the texture cache by calling intel_batchbuffer_emit_mi_flush after doing any rendering. If we were to use the normal drawing path, then brw_postdraw_set_buffers_need_resolve would handle this. On Broadwell, we don't use BLORP, and we don't emit a rectangle primitive via the normal drawing path. The 3DSTATE_WM_HZ_OP and PIPE_CONTROL implicitly make drawing happen. So, none of our existing code makes this flush happen - we need to do it directly. Fixes 11 Piglit copyteximage subtests.

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 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. 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.
