The INTEL_performance_query extension provides a list of queries that a user can select to monitor a particular workload. Each query reports different sets of counters (roughly looking at different parts of the hardware, i.e. caches/fixed functions/etc...). Each query has an associated configuration that we need to program into the hardware before using the query. Up to now, we provided predefined queries. This change allows the user to build its own query (and associated configuration) externally, and have the i965 driver use that configuration through a new query named : Intel_Raw_Hardware_Counters_Set_0_Query When this query is selected, the i965 driver will report raw counters deltas (meaning their values need to be interpreted by the user, as opposed to existing queries that provide human readable values). This change is also useful for debug purposes for building new pre-defined queries and verifying the underlying numbers make sense before writing equations for user readable output. This change's purpose is also to enable GPA. GPA uses a library called MDAPI that processes raw counter data. MDAPI expects raw data to have a certain layout (per generation which is a bit unfortunate...). This change also embeds the expected data layouts. v2: Enable raw queries on gen 7->11, v1 had 7->9 (Lionel) v3: Don't assert on cherryview for gen7...

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.
