Lionel Landwerlin 31b11f69f7 i965: perf: keep on reading reports until delimiting timestamp
Due to an underlying hardware race condition, we have no guarantee
that all the reports coming from the OA buffer related to the workload
we're trying to measure have landed to memory by the time all the work
submitted has completed. That means we need to keep on reading the OA
stream until we read a report with a timestamp more recent than the
timestamp recored by the MI_REPORT_PERF_COUNT at the end of the
performance query.

v2: fix uninitialized offset variable to 0 (Lionel)

v3: rework the reading to avoid blocking the user of the API unless
    requested (Rob)

v4: fix a bug that makes the i965 driver reading the perf stream when
    not necessary, leading to very long counter accumulation times
    (Lionel)

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.
