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.
Volker Rümelin (11):
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: add function kbd_pending()
pckbd: correctly disable PS/2 communication
pckbd: remove duplicated keyboard and mouse defines
I'm sorry, there is a bug somewhere in this series. Seabios sometimes
doesn't detect the PS/2 keyboard. Please ignore this series for now.
This is a Seabios bug. Seabios expects the PS/2 controller doesn't
generate interrupts after it sends the command KBD_CCMD_KBD_DISABLE
to the controller. Even the original author of the pckbd code wrote
in a comment that this is incorrect. I will send a version 3 series
where I don't fix the incorrectness.
With best regards,
Volker
