+Description
+-----------
+
+This driver permits reading of the internal temperature sensor of AMD
+Family 10h and 11h processors.
+
+All these processors have a sensor, but on older revisions of Family 10h
+processors, the sensor may return inconsistent values (erratum 319). 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.
+Output files
+
+modules.order
+--------------------------------------------------
+This file records the order in which modules appear in Makefiles. This
+is used by modprobe to deterministically resolve aliases that match
+multiple modules.
+
+modules.builtin
+--------------------------------------------------
+This file lists all modules that are built into the kernel. This is used
+by modprobe to not fail when trying to load something builtin.
+
+
Environment variables
KCPPFLAGS
This environment variable can be set to specify the path & name of the
"auto.conf" file. Its default value is "include/config/auto.conf".
+KCONFIG_TRISTATE
+--------------------------------------------------
+This environment variable can be set to specify the path & name of the
+"tristate.conf" file. Its default value is "include/config/tristate.conf".
+
KCONFIG_AUTOHEADER
--------------------------------------------------
This environment variable can be set to specify the path & name of the
-"autoconf.h" (header) file. Its default value is "include/linux/autoconf.h".
+"autoconf.h" (header) file.
+Its default value is "include/generated/autoconf.h".
