With the last few patches, the PS/2 con- troller behaves more like a real controller. Volker Rümelin (10):   ps2: fix mouse stream corruption   ps2: don't raise an interrupt if queue is full   ps2: don't deassert irq twice if queue is empty   pckbd: split out interrupt line changing code   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   pckbd: correctly disable PS/2 communication   pckbd: remove duplicated keyboard and mouse defines  hw/input/pckbd.c | 293 ++++++++++++++++++++++++++++++++++-------------  hw/input/ps2.c   |  11 +-  2 files changed, 223 insertions(+), 81 deletions(-)
