Error state files used to look like: render ring --- gtt_offset = 0x0e8f6000 00000000 : 69040000 00000004 : 79090000 ... 00007ffc : 00000000 --- ringbuffer = 0x00001000 There were thousands of lines between sections. The file format changed with Kernel 4.10, and now has a single ascii85-encoded line following each section heading. This is much easier to parse. There are a bunch of bugs in our handling of the old style format, where we'd decode the wrong data, at the wrong time. Fixing all of these is going to be a giant pain. It's also a lot of extra code complexity. In order to properly decode indirect state, or compute shaders, we'll also need to parse data in advance of decoding, which is going to be a giant pain with this ad-hoc "decode everywhere!" mentality. So, let's just drop support for the older file format. This unfortunately requires an error state generated by Kernel 4.10 or later. That's probably not the end of the world, as we encourage users to upgrade to the latest kernel when encountering GPU hangs anyway. It might be a giant pain for people with LTS kernels, though...

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.
