Chris Wilson 71fa292d48 i965: Prevent coordinate overflow in intel_emit_linear_blit 
Fixes regression from
commit 8c17d53823
Author: Kenneth Graunke <kenneth@whitecape.org>
Date:   Wed Apr 15 03:04:33 2015 -0700

    i965: Make intel_emit_linear_blit handle Gen8+ alignment restrictions.

which adjusted the coordinates to be relative to the nearest cacheline.
However, this then offsets the coordinates by up to 63 and this may then
cause them to overflow the BLT limits. For the well aligned large
transfer case, we can use 32bpp pixels and so reduce the coordinates by
4 (versus the current 8bpp pixels). We also have to be more careful
doing the last line just in case it may exceed the coordinate limit.

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 http://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.
