The +driver will refuse to load on these revisions unless you specify the +"force=1" module parameter. + +There is one temperature measurement value, available as temp1_input in +sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree. +Please note that it is defined as a relative value; to quote the AMD manual: + + Tctl is the processor temperature control value, used by the platform to + control cooling systems. Tctl is a non-physical temperature on an + arbitrary scale measured in degrees. It does _not_ represent an actual + physical temperature like die or case temperature. Instead, it specifies + the processor temperature relative to the point at which the system must + supply the maximum cooling for the processor's specified maximum case + temperature and maximum thermal power dissipation. + +The maximum value for Tctl is available in the file temp1_max. + +If the BIOS has enabled hardware temperature control, the threshold at +which the processor will throttle itself to avoid damage is available in +temp1_crit and temp1_crit_hyst. diff --git a/Documentation/kbuild/kbuild.txt b/Documentation/kbuild/kbuild.txt index bb3bf38f03d..6f8c1cabbc5 100644 --- a/Documentation/kbuild/kbuild.txt +++ b/Documentation/kbuild/kbuild.txt @@ -1,3 +1,17 @@ +Output files + +modules.order +-------------------------------------------------- +This file records the order in which modules appear in Makefiles.
