Following up cc'd to acpi and the presumed
maintainer:
Over on -mobile we've been exploring ways to help Norberto
stop his
(6-STABLE) Thinkpad z60m from melting - well, regularly
hitting critical
thermal shutdown on larger builds - and these fan speed
control sysctls
came up, along with a neat perl daemon using them to control
fan speed
vs temperature setpoints (plus powerd-like cpu freq
adjustment when it
gets hotter than maximum fan speed control can manage).
Running 7 sounds good, but is there any particular (API?)
reason that
- Add support for setting the fan control mode to manual or
automatic
- Add support for adjusting the fan speed if the fan
control mode is manual
from acpi_ibm.c rev 1.10, was not MFC'd to 6-STABLE?
If not, any chance before 6.3?
Cheers, Ian
