Kenneth Graunke 3bec992e36 i965: Fix brw_finish_batch to grow the batchbuffer.
brw_finish_batch emits commands needed at the end of every batch buffer,
including any workarounds.  In the past, we freed up some "reserved"
batch space before calling it, so we would never have to flush during
it.  This was error prone and easy to screw up, so I deleted it a while
back in favor of growing the batch.

There were two problems:

1. We're in the middle of flushing, so brw->no_batch_wrap is guaranteed
   not to be set.  Using BEGIN_BATCH() to emit commands would cause a
   recursive flush rather than growing the buffer as intended.

2. We already recorded the throttling batch before growing, which
   replaces brw->batch.bo with a different (larger) buffer.  So growing
   would break throttling.

These are easily remedied by shuffling some code around and whacking
brw->no_batch_wrap in brw_finish_batch().  This also now includes the
final workarounds in the batch usage statistics.  Found by inspection.

Fixes: 2c46a67b41 (i965: Delete BATCH_RESERVED handling.)

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.
