KG(4) BSD/vax Kernel Interfaces Manual KG(4)NAMEkg — KL-11/ DL-11W line clock
device kg0 at uba0 csr 0176500 vector kglock
A KL-11 or DL-11W can be used as an alternate real time clock source.
When configured, certain system statistics and, optionally, system pro‐
filing work will be collected each time the clock interrupts. For opti‐
mum accuracy in profiling, the DL-11W should be configured to interrupt
at the highest possible priority level. The kg device driver automati‐
cally calibrates itself to the line clock frequency.

The kg driver appeared in 4.2BSD.
