- help
- Some versions of the PPC601 (the first PowerPC chip) have bugs which
- mean that extra synchronization instructions are required near
- certain instructions, typically those that make major changes to the
- CPU state. These extra instructions reduce performance slightly.

-config TAU

- 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.
-
- If in doubt, say N here.

+ 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

+ 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

/*
* 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.
