In preparation for generating code from the XML performance counter meta
data, this makes some additions to brw_context.h for this code to be
able to reference.
It adds a brw->perfquery.oa_metrics_table hash table for indexing built
up query descriptions by the GUID that is expected to be advertised by
the kernel (via sysfs) to be able to use that query.
It adds an 'OA_COUNTERS' brw_query_kind to be assigned to queries built
up by generated code.
It adds a brw->perfquery.sys_vars structure to have a consistent place
to represent the different system variables like $EuCoresTotalCount and
$EuSlicesTotalCount that are referenced by OA counter normalization
equations.
Although extending + referencing gen_device_info for these variables
was considered, these are some of the (mostly minor) reasons for
going with a dedicated structure:
- Currently we only need this info for the performance_query backend
and it might be a bit tedious to go back and initialize the state
for pre-Haswell devinfo structures.
- Considering the $SubsliceMask then the requirement for how multiple
per-slice masks are packed only comes from how the variables are
references by availability tests in XML, and might not be a good
general representation for tracking subslice masks if another use
case arises.
- If we used gen_device_info then we'd likely want to avoid making
assumptions about the C types during codegen and adding explicit
casts, while that's not necessary with a dedicated struct with all
members being uint64_t.
- This structure and the code for initializing it is currently shared
(just through copy & paste) with a few other projects dealing with
OA counters, and that's been convenient so far.

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.
