The celleb code has seen no actual development for ~7 years. We (maintainers) have no access to test hardware, and it is highly likely the code has bit-rotted. As far as we're aware the hardware was never widely available, and is certainly no longer available, and no one on the list has shown any interest in it over the years. So remove it. If anyone has one and cares please speak up. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Jeremy Kerr <jk@ozlabs.org>

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

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.

config TAU_AVERAGE

bool "Average high and low temp"

---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.
