There are four types of PowerPC chips supported. The more common
|
|
types (601, 603, 604, 740, 750, 7400), the older Freescale
|
|
(formerly Motorola) embedded versions (821, 823, 850, 855, 860,
|
|
52xx, 82xx, 83xx), the IBM embedded versions (403 and 405) and
|
|
the Book E embedded processors from IBM (44x) and Freescale (85xx).
|
|
For support for 64-bit processors, set ARCH=powerpc.
|
|
Unless you are building a kernel for one of the embedded processor
|
|
systems, choose 6xx.
|
|
Also note that because the 52xx, 82xx, & 83xx family have a 603e

core, specific support for that chipset is asked later on.

bool "Thermal Management 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 some 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.

config MATH_EMULATION

bool "Math emulation"

depends on 4xx || 8xx || E200 || E500
|
|
---help---
|
|
Some PowerPC chips designed for embedded applications do not have
|
|
a floating-point unit and therefore do not implement the
|
|
floating-point instructions in the PowerPC instruction set. If you
|
|
say Y here, the kernel will include code to emulate a floating-point
|
|
unit, which will allow programs that use floating-point
|
|
instructions to run.
|
|
|
|
If you have an Apple machine or an IBM RS/6000 or pSeries machine,
|
|
or any machine with a 6xx, 7xx or 7xxx series processor, say N
|
|
here. Saying Y here will not hurt performance (on any machine) but

|
will increase the size of the kernel.

config KEXEC
|
|
bool "kexec system call (EXPERIMENTAL)"
|
|
depends on EXPERIMENTAL
|
|
help
|
|
kexec is a system call that implements the ability to shutdown your
|
|
current kernel, and to start another kernel. It is like a reboot
|
|
but it is independent of the system firmware. And like a reboot
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
The name comes from the similarity to the exec system call.
|
|
|
|
It is an ongoing process to be certain the hardware in a machine
|
|
is properly shutdown, so do not be surprised if this code does not
|
|
initially work for you. It may help to enable device hotplugging
|
|
support. As of this writing the exact hardware interface is
|
|
strongly in flux, so no good recommendation can be made.
|
|
|
|
In the GameCube implementation, kexec allows you to load and
|
|
run DOL files, including kernel and homebrew DOLs.

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.

If in doubt, say Y here.

Find out whether your system includes a PCI bus. PCI is the name of
|
|
a bus system, i.e. the way the CPU talks to the other stuff inside
|
|
your box. If you say Y here, the kernel will include drivers and
|
|
infrastructure code to support PCI bus devices.
