This patch series fixes two different PS/2 mouse stream corruptions
and adds a feature that allows some old misbehaving DOS programs to
have a working keyboard. With the last few patches, the PS/2 con-
troller behaves more like a real controller.
v2:
Introduce the function kbd_pending() in a preliminary patch to ease
the review of patch "pckbd: correctly disable PS/2 communication",
as Philippe suggested.
v3:
Patch "pckbd: correctly disable PS/2 communication" exposed a bug
in SeaBIOS. The updated patch keeps the relevant code. Until
SeaBIOS is fixed, the PS/2 controller command KBD_CCMD_KBD_DISABLE
must disable the keyboard interrupt.
In patch "pckbd: PS/2 keyboard throttle" in function
kbd_throttle_timeout() an unnecessary if statement was removed.
The KBD_STAT_OBF flag is never set when kbd_throttle_timeout()
gets called.
v4:
Use a subsection for additional pckbd state variables. This allows
users to migrate old qemu to new qemu and back. Patches
"pckbd: don't update OBF flags if KBD_STAT_OBF is set",
"pckbd: PS/2 keyboard throttle",
"pckbd: add state variable for interrupt source",
"pckbd: add controller response queue" and
"pckbd: correctly disable PS/2 communication" look now a little
bit different.
New patch "pckbd: clear outport_present in outer pre_load()".
