NAME
kg —
KL-11/DL-11W line clock
SYNOPSIS
kg0 at uba0 csr 0176500 vector kglock
DESCRIPTION
NOTE: This driver has not been ported from
4.4BSD yet.
A KL-11 or DL-11W can be used as an alternative real time clock source. When
configured, certain system statistics and, optionally, system profiling work
will be collected each time the clock interrupts. For optimum accuracy in
profiling, the DL-11W should be configured to interrupt at the highest
possible priority level. The
kg device driver automatically
calibrates itself to the line clock frequency.
