[Qemu-devel] [PATCH 0 of 5] [UPDATE] vnc, sdl and vga improvements, opengl implementation

[Stefano Stabellini]

Hi all,
this is an updated version of the three patch series I posted few days
ago to implement a shared buffer between vnc and vga.

I decided to append to this series the sdl shared buffer patch and the
opengl implementation for simplicity, but keep in mind that the first
three patches make perfect sense even without the latter two.

The only changes are few ifdef lines to disable the shared buffer in
case that the host and the guest have different endianness.

---

The first patch implements dynamic colour depth changes in vnc.c:
this way the vnc server can change its own internal colour depth at run
time to follow any guest resolution change.

The second patch implements the WMVi vnc extension in the qemu vnc
server, so that we can also notify a vnc client when we change
internal colour depth and offload any possible colour conversion to the
client.

The third patch implements sharing of the display pixel buffer between
vnc.c and vga.c, in order to save a lot of memcpy's.

The fourth patch implements shared buffer support in sdl.c.
It also supports paletted 8 bit colour depths using the
palette functions provided by the SDL library.

The fifth patch adds opengl support for rendering the guest framebuffer
in the SDL window.
