[Qemu-devel] [RfC PATCH 00/12] console/display: cleanup & untangle data structures.

[Gerd Hoffmann <kraxel@redhat.com>]

  Hi,

This patch series continues the console & display code cleanups.
It's RfC because it is (a) not complete yet and (b) most likely
breaks the build (xen, cocoa).  If someone wants help fill the
gaps (especially cocoa) patches are very welcome.

The short-team goal I'm heading to is to make the DisplaySurface
(and *only* the DisplaySurface) the central data structure for
the display renderers in ui/.  They get one, they render it, they
are notified about updates, they are notified when the surface
changes.  Done, there is nothing else they need to know or care
about.

The longer-term goal building on top of this is to put the console
internals upside down (without having to touch the ui renderers in
the process).  I want have one DisplaySurface per console, which then
lives forever, and console switches (Ctrl-Alt-$number in vnc+sdl)
become a simple surface switch.  Alternative ways to handle consoles
becomes alot easier to implement, in gtk we can probably simply put
each DisplaySurface into one tab.  The need to ask the vga emulation
to redraw the screen on console switches goes away, vga_hw_invalidate
can be zapped.  We can stop hopping through loops for screendumps,
we can just write out the DisplaySurface content.

Oh, and this also paves the way to handle multihead in a reasonable
way.

cheers,
  Gerd
