Once the driver moves to ISL both compressed and uncompressed have the same type. One needs to tell them apart by other means. This can be done by checking the existence of mcs_buf. There is a short period of time within intel_miptree_create() where mcs_buf doesn't exist yet (between calls to intel_miptree_create_layout() and intel_miptree_alloc_mcs()). First compute_msaa_layout() makes the decision if compression is to be used and sets the msaa_layout type. Then based on the type one sets aux_usage and finally decides if mcs_buf is needed. This patch duplicates the logic in compute_msaa_layout() and uses that to make the decision on aux_usage and mcs_buf allocation. Most of the original logic in compute_msaa_layout() will be gone in later patch leaving only one version. Elsewhere only brw_populate_sampler_prog_key_data() needs to know if compression is used based on the msaa_type. This is now replaced with consideration for number of samples and existence of mcs_buf. All other occurrences consider CMS || UMS which can be represented using single the type of ISL_MSAA_LAYOUT_ARRAY without any tweaks.

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.
