CVS commit: syssrc



Module Name:    syssrc
Committed By:   jdolecek
Date:           Sat Jun  2 00:01:05 UTC 2001

        syssrc/sys/arch/i386/isa: pccons.c
        syssrc/sys/dev/ic: pckbc.c

Log Message:
When polling, raise priority level to tty, to block keyboard interrupts
when the system is "warm", i.e. interrupts are not blocked anymore.
This seems to be necessary on my PS/2 Model 70 keyboard - without this,
system ends up in endless loop calling the keyboard intr routine if a key
is pressed when polling. This _may_ be just specific to level-triggered
interrupts PS/2 MCA uses, though it's more likely it's just the way the
particular keyboard controller works.

Discussed on tech-kern@.
