$OpenBSD: patch-src_print_cpu_temperature_c,v 1.5 2012/10/09 17:12:31 jasper Exp $
|

|
|
- Default to acpitz(4) for temperature readings, instead of cpu(4).
|
|
The acpitz(4) values are eventually used by the kernel to determine if the machine
|
|
is getting too hot.
|
|
|
|
Other devices can be used by setting 'path' in the config file to the sysctl(3)
|
|
device node.
|
|
|
|
- Temperature sensors can now set a 'max_threshold' value to color the
|
|
output red if exceeded.
