Management of Thermal (fwd)

[Ian Smith]

Hi,

Maybe pertinent to current discussions of thermal management on various
thinkpads .. I just checked acpi_ibm.c 1.7.2.4 (6.x) and see that it
still doesn't include the fan level support introduced to 7.x at 1.10

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/acpi_support/acpi_ibm.c.diff?r1=text&tr1=1.10&r2=text&tr2=1.7.2.4

Is there any particular reason this wasn't / can't be MFC'd to 6.x?

cheers, Ian

You are absolutely right. On my stable tree I MFC'ed the acpi_ibm a few times
myself. Totaly forget about it :) Now i'm running the normal acpi_ibm in stable
again and indeed the fan_level hook isn't there anymore.

Adapting acpi_ibm to stable was not that hard but you can also try to run
RELENG_7, it is fairly stable at the moment :)
