Moved, renamed, and deleted files
The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

The driver +will refuse to load on these revisions unless you specify the "force=1" +module parameter. + +Due to technical reasons, the driver can detect only the mainboard's +socket type, not the processor's actual capabilities. Therefore, if you +are using an AM3 processor on an AM2+ mainboard, you can safely use the +"force=1" 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. |
