George Kyriazis b9aa0fa7d6 swr: Handle resource across context changes
Swr caches fb contents in tiles.  Those tiles are stored on a per-context
basis.

When switching contexts that share resources we need to make sure that
the tiles of the old context are being stored and the tiles of the new
context are being invalidated (marked as invalid, hence contents need
to be reloaded).

The context does not get any dirty bits to identify this case.  This has
to be, then, coordinated by the resources that are being shared between
the contexts.

Add a "curr_pipe" hook in swr_resource that will allow us to identify a
MakeCurrent of the above form during swr_update_derived().  At that time,
we invalidate the tiles of the new context.  The old context, will need to
have already store its tiles by that time, which happens during glFlush().
glFlush() is being called at the beginning of MakeCurrent.

So, the sequence of operations is:
- At the beginning of glXMakeCurrent(), glFlush() will store the tiles
  of all bound surfaces of the old context.
- After the store, a fence will guarantee that the all tile store make
  it to the surface
- During swr_update_derived(), when we validate the new context, we check
  all resources to see what changed, and if so, we invalidate the
  current tiles.

Fixes rendering problems with CEI/Ensight.

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.
