-        bool "On-chip CPU temperature sensor support"

-        help
-          G3 and G4 processors have an on-chip temperature sensor called the
-          'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
-          temperature within 2-4 degrees Celsius. This option shows the current
-          on-die temperature in /proc/cpuinfo if the cpu supports it.
-
-          Unfortunately, on some chip revisions, this sensor is very inaccurate
-          and in many cases, does not work at all, so don't assume the cpu
-          temp is actually what /proc/cpuinfo says it is.

-config TAU_INT
-        bool "Interrupt driven TAU driver (DANGEROUS)"

-        ---help---
-          The TAU supports an interrupt driven mode which causes an interrupt
-          whenever the temperature goes out of range. This is the fastest way
-          to get notified the temp has exceeded a range. With this option off,
-          a timer is used to re-check the temperature periodically.
-
-          However, on some cpus it appears that the TAU interrupt hardware
-          is buggy and can cause a situation which would lead unexplained hard
-          lockups.
-
-          Unless you are extending the TAU driver, or enjoy kernel/hardware
-          debugging, leave this option off.

-          The TAU hardware can compare the temperature to an upper and lower
-          bound.  The default behavior is to show both the upper and lower
-          bound in /proc/cpuinfo. If the range is large, the temperature is
-          either changing a lot, or the TAU hardware is broken (likely on some
-          G4's). If the range is small (around 4 degrees), the temperature is
-          relatively stable.  If you say Y here, a single temperature value,
-          halfway between the upper and lower bounds, will be reported in
-          /proc/cpuinfo.

+          If you say N here, these extra instructions will not be included,
+          resulting in a kernel which will run faster but may not run at all

+        help
+          G3 and G4 processors have an on-chip temperature sensor called the
+          'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
+          temperature within 2-4 degrees Celsius. This option shows the current
+          on-die temperature in /proc/cpuinfo if the cpu supports it.
+
+          Unfortunately, on some chip revisions, this sensor is very inaccurate
+          and in many cases, does not work at all, so don't assume the cpu
+          temp is actually what /proc/cpuinfo says it is.
+
+config TAU_INT
+        bool "Interrupt driven TAU driver (DANGEROUS)"
+        depends on TAU
+        ---help---
+          The TAU supports an interrupt driven mode which causes an interrupt
+          whenever the temperature goes out of range. This is the fastest way
+          to get notified the temp has exceeded a range. With this option off,
+          a timer is used to re-check the temperature periodically.
+
+          However, on some cpus it appears that the TAU interrupt hardware
+          is buggy and can cause a situation which would lead unexplained hard
+          lockups.
+
+          Unless you are extending the TAU driver, or enjoy kernel/hardware
+          debugging, leave this option off.

+config TAU_AVERAGE
+        bool "Average high and low temp"
+        depends on TAU
+        ---help---
+          The TAU hardware can compare the temperature to an upper and lower
+          bound.  The default behavior is to show both the upper and lower
+          bound in /proc/cpuinfo. If the range is large, the temperature is
+          either changing a lot, or the TAU hardware is broken (likely on some
+          G4's). If the range is small (around 4 degrees), the temperature is
+          relatively stable.  If you say Y here, a single temperature value,
+          halfway between the upper and lower bounds, will be reported in
+          /proc/cpuinfo.

 /*
  * thermal support for the cell processor
  *
+ * This module adds some sysfs attributes to cpu and spu nodes.
+ * Base for measurements are the digital thermal sensors (DTS)
+ * located on the chip.
+ * The accuracy is 2 degrees, starting from 65 up to 125 degrees celsius
+ * The attributes can be found under
+ * /sys/devices/system/cpu/cpuX/thermal
+ * /sys/devices/system/spu/spuX/thermal
+ *
+ * The following attributes are added for each node:
+ * temperature:
+ *      contains the current temperature measured by the DTS
+ * throttle_begin:
+ *      throttling begins when temperature is greater or equal to
+ *      throttle_begin. Setting this value to 125 prevents throttling.
+ * throttle_end:
+ *      throttling is being ceased, if the temperature is lower than
+ *      throttle_end. Due to a delay between applying throttling and
+ *      a reduced temperature this value should be less than throttle_begin.
+ *      A value equal to throttle_begin provides only a very little hysteresis.
+ * throttle_full_stop:
+ *      If the temperatrue is greater or equal to throttle_full_stop,
+ *      full throttling is applied to the cpu or spu. This value should be
+ *      greater than throttle_begin and throttle_end. Setting this value to
+ *      65 prevents the unit from running code at all.
