Hi,
Second round of the framebuffer display driver patches.
Changes: Addressed the review comments. Added a few more patches on
top: Using the pixman library for raster ops now. Added support for
mouse pointer rendering and guest display scaling.
cheers,
Gerd
Gerd Hoffmann (9):
QLIST-ify display change listeners.
add unregister_displaychangelistener
move set_mouse + cursor_define callbacks
fbdev: add linux framebuffer display driver.
fbdev: add monitor command to enable/disable
fbdev: make configurable at compile time.
fbdev: move to pixman
fbdev: add mouse pointer support
fbdev: add display scaling support

The framebuffer is used as-is, qemu doesn't try to switch modes. With LCD displays mode switching is pretty pointless IMHO, also it wouldn't work anyway with the most common fbdev drivers (vesafb, KMS). Guest display is centered on the host screen. Mouse works, uses /dev/input/mice. Keyboard works. Guest screen has whatever keymap you load inside the guest. Text windows (monitor, serial, ...) have a simple en-us keymap. Good enougth to type monitor commands. Not goot enougth to work seriously on a serial terminal. But the qemu terminal emulation isn't good enough for that anyway ;) Hot keys: Ctrl-Alt-F<nr> -> host console switching. Ctrl-Alt-<nr> -> qemu console switching. Ctrl-Alt-ESC -> exit qemu. Special feature: Sane console switching. Switching away stops screen updates. Switching back redraws the screen. When started from the linux console qemu uses the vt you've started it from (requires just read/write access to /dev/fb0). When starting from somewhere else qemu tries to open a unused virtual terminal and switch to it (usually requires root privileges to open /dev/tty<nr>).
