depends on 6xx && (PPC_PREP || PPC_PMAC)
|

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.
|
|
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
|
|
on some systems with the PPC601 chip.

config TAU

bool "On-chip CPU temperature sensor support"
|

depends on 6xx
|
|
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.
