[Qemu-devel] [PATCH] Experimental patch providing accelerated OpenGL for Linux i386 (update as of 2007-02-28)

[Even Rouault]

The patch has been updated and is available at 
http://qemu-forum.ipi.fi/viewtopic.php?t=2984

Changes/Improvements since second patch version (10 February 2007)
------------------------------------------------------------------
* Initial support for Windows as a guest (still Linux i386 as a host)!
  Guest supported API is WGL/OpenGL (opengl32.dll). Really minimum and hackish 
implementation, but enough to make Windows GoogleEarth run
* Better visual integration : 
     - OpenGL window is now child of QEMU SDL window, so it seems to be
       "naturally" integrated into the virtual machine.
     - Mouse cursor is drawned on top of the GL drawing. (This works only
       if the GL drawing is refreshed in a loop, and with a Linux guest)
* Better support of NVIDIA chips
* Fix annoying bug in QEMU serialization protocol that caused QEMU crashes 
when serialized buffer was exactly a multiple of target page size (aka. 
ppracer bug)
* gl(Get)PolygonStipple fix and other OpenGL implementation fixes
* Small improvements to make more Mesa demos run
* License change to MIT license.

How does this compare to chromium[1] and in particular vmgl[2] ?

Any particular reason you're re-inventing the wheel?

In fact I have discovered the existence of these software just a few days ago 
thanks to comments from other people on the QEMU forum. But I've not yet 
tried any of them.

Apparently, when reading the home page of wmgl, "VMGL is available for 
X11-based guest OS's: Linux, FreeBSD and OpenSolaris"

As far as chromium is concerned, someone has posted "I've tried chromium with 
windows guest in qemu a few months ago. The network throughput is the 
limiting factor - one needs to write a custom transport driver." Don't know 
how limiting it is.
