132 There are four families of PowerPC chips supported. The more common
133 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
134 versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC
135 embedded versions (403 and 405) and the high end 64 bit Power
136 processors (POWER 3, POWER4, and IBM PPC970 also known as G5).
138 This option is the catch-all for 6xx types, including some of the
139 embedded versions. Unless there is see an option for the specific
140 chip family you are using, you want this option.
142 You do not want this if you are building a kernel for a 64 bit
143 IBM RS/6000 or an Apple G5, choose 6xx.

286 altivec registers, and turning on the 'altivec enable' bit so user
287 processes can execute altivec instructions.
289 This option is only usefully if you have a processor that supports

328 kernel entry and exit and on transitions within the kernel
329 between system, softirq and hardirq state, so there is a
330 small performance impact. This also enables accounting of

342 than one CPU, say Y. Note that the kernel does not currently
343 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
344 since they have inadequate hardware support for multiprocessor

348 machines, but will use only one CPU of a multiprocessor machine. If

676 depends on 6xx && (PPC_PREP || PPC_PMAC)
678 Some versions of the PPC601 (the first PowerPC chip) have bugs which
679 mean that extra synchronization instructions are required near
680 certain instructions, typically those that make major changes to the
681 CPU state. These extra instructions reduce performance slightly.
682 If you say N here, these extra instructions will not be included,
683 resulting in a kernel which will run faster but may not run at all
684 on some systems with the PPC601 chip.
686 If in doubt, say Y here.
689 bool "On-chip CPU temperature sensor support"
692 G3 and G4 processors have an on-chip temperature sensor called the
693 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
694 temperature within 2-4 degrees Celsius. This option shows the current
695 on-die temperature in /proc/cpuinfo if the cpu supports it.
697 Unfortunately, on some chip revisions, this sensor is very inaccurate
698 and in many cases, does not work at all, so don't assume the cpu
699 temp is actually what /proc/cpuinfo says it is.
702 bool "Interrupt driven TAU driver (DANGEROUS)"
705 The TAU supports an interrupt driven mode which causes an interrupt
706 whenever the temperature goes out of range. This is the fastest way
707 to get notified the temp has exceeded a range. With this option off,
708 a timer is used to re-check the temperature periodically.
710 However, on some cpus it appears that the TAU interrupt hardware
711 is buggy and can cause a situation which would lead unexplained hard
714 Unless you are extending the TAU driver, or enjoy kernel/hardware
715 debugging, leave this option off.
718 bool "Average high and low temp"
721 The TAU hardware can compare the temperature to an upper and lower
722 bound. The default behavior is to show both the upper and lower
723 bound in /proc/cpuinfo. If the range is large, the temperature is
724 either changing a lot, or the TAU hardware is broken (likely on some
725 G4's). If the range is small (around 4 degrees), the temperature is
726 relatively stable. If you say Y here, a single temperature value,
727 halfway between the upper and lower bounds, will be reported in
730 If in doubt, say N here.

800 bool "kexec system call (EXPERIMENTAL)"
801 depends on PPC_MULTIPLATFORM && EXPERIMENTAL
803 kexec is a system call that implements the ability to shutdown your
804 current kernel, and to start another kernel. It is like a reboot
805 but it is independent of the system firmware. And like a reboot
806 you can start any kernel with it, not just Linux.
808 The name comes from the similarity to the exec system call.
810 It is an ongoing process to be certain the hardware in a machine
811 is properly shutdown, so do not be surprised if this code does not
812 initially work for you. It may help to enable device hotplugging
813 support. As of this writing the exact hardware interface is

1125 This option allows you to set the kernel virtual address at which
1126 the kernel will map low memory (the kernel image will be linked at
1127 this address). This can be useful in optimizing the virtual memory
1128 layout of the system.

1228 a probepoint and specifies the callback. Kprobes is useful
1229 for kernel debugging, non-intrusive instrumentation and testing.
