Marek Olšák a77ee8b548 radeonsi: simplify and improve flushing
This mimics r600g. The R600_CONTEXT_xxx flags are added to rctx->b.flags
and si_emit_cache_flush emits the packets. That's it. The shared radeon code
tells us when the streamout cache should be flushed, so we have to check
the flags anyway.

There is a new atom "cache_flush", because caches must be flushed *after*
resource descriptors are changed in memory.

Functional changes:

* Write caches are flushed at the end of CS and read caches are flushed
  at its beginning.

* Sampler view states are removed from si_state, they only held the flush
  flags.

* Everytime a shader is changed, the I cache is flushed. Is this needed?
  Due to a hw bug, this also flushes the K cache.

* The WRITE_DATA packet is changed to use TC, which fixes a rendering issue
  in openarena. I'm not sure how TC interacts with CP DMA, but for now it
  seems to work better than any other solution I tried. (BTW CIK allows us
  to use TC for CP DMA.)

* Flush the K cache instead of the texture cache when updating resource
  descriptors (due to a hw bug, this also flushes the I cache).
  I think the K cache flush is correct here, but I'm not sure if the texture
  cache should be flushed too (probably not considering we use TC
  for WRITE_DATA, but we don't use TC for CP DMA).

* The number of resource contexts is decreased to 16. With all of these cache
  changes, 4 doesn't work, but 8 works, which suggests I'm actually doing
  the right thing here and the pipeline isn't drained during flushes.

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 osmesa mesagdi

to build classic mesa Windows GDI drivers; or

  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.

1) install python 2.7
2) install scons (latest)
3) install mingw, flex, and bison
4) install libxml2 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get libxml2-python-2.9.1.win-amd64-py2.7.exe
5) install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get pywin32-218.4.win-amd64-py2.7.exe
6) install git
7) download mesa from git
  see http://www.mesa3d.org/repository.html
8) 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.
