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.

285 PowerPC processor. The kernel currently supports saving and restoring
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

306 This option is only useful 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

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

762 Cause IO segments sent to a device for DMA to be merged virtually

783 depends on PPC_MULTIPLATFORM && EXPERIMENTAL
785 kexec is a system call that implements the ability to shutdown your
786 current kernel, and to start another kernel. It is like a reboot
787 but it is independent of the system firmware. And like a reboot
788 you can start any kernel with it, not just Linux.
790 The name comes from the similarity to the exec system call.
792 It is an ongoing process to be certain the hardware in a machine
793 is properly shutdown, so do not be surprised if this code does not
794 initially work for you. It may help to enable device hotplugging
795 support. As of this writing the exact hardware interface is

1112 This option allows you to set the kernel virtual address at which
1113 the kernel will map low memory (the kernel image will be linked at
1114 this address). This can be useful in optimizing the virtual memory
1115 layout of the system.
