clock
— Clock
driver for Motorola MVME68K Single Board Computers
clock0 at pcc? ipl 5
clock0 at pcctwo? ipl 5
The clock
driver uses the counter/timer
facilities of the MVME147's pcc
driver or the
MVME167/MVME177's pcctwo
driver to provide two
independent hardware clocks for use by the NetBSD
kernel.
Both clock interrupts are set to 100Hz, with one used to provide the master kernel stats clock tick. The other is used for profiling purposes.
