lmdriver provides support for the National Semiconductor LM78/79/81 hardware monitors and register compatible chips to be used with the sysctl(8) interface.
The original LM78 hardware monitor supports 11 sensors:
||uV DC||Core voltage|
For other devices, sensors' names and numbers will be different.
Some devices can attach to both
isa(4); others can only attach to either one
or the other. If the
lm driver detects a device
attaching to both iic(4) and
isa(4), it will detach the device from
lmdriver first appeared in NetBSD 1.5; OpenBSD support was added in OpenBSD 3.4.
lmdriver was written by Bill Squier and ported to OpenBSD 3.4 by Alexander Yurchenko <email@example.com>. The driver was largely rewritten for OpenBSD 3.9 by Mark Kettenis <firstname.lastname@example.org>.
There are currently no known pnpbios IDs assigned to LM chips.
This driver attaches to the Winbond W83791SD chip even though that chip does not have any sensors.
