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

272 processes can execute altivec instructions.
274 This option is only usefully if you have a processor that supports

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

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

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

726 depends on EXPERIMENTAL && PPC64
729 Cause IO segments sent to a device for DMA to be merged virtually
730 by the IOMMU when they happen to have been allocated contiguously.
731 This doesn't add pressure to the IOMMU allocator. However, some

749 bool "kexec system call (EXPERIMENTAL)"
750 depends on PPC_MULTIPLATFORM && EXPERIMENTAL
752 kexec is a system call that implements the ability to shutdown your
753 current kernel, and to start another kernel. It is like a reboot
754 but it is independent of the system firmware. And like a reboot
755 you can start any kernel with it, not just Linux.
757 The name comes from the similarity to the exec system call.
759 It is an ongoing process to be certain the hardware in a machine
760 is properly shutdown, so do not be surprised if this code does not
761 initially work for you. It may help to enable device hotplugging
762 support. As of this writing the exact hardware interface is
763 strongly in flux, so no good recommendation can be made.

1105 memory is used to make consistent memory allocations.

1127 This option allows you to set the initial load address of the zImage
1128 or zImage.initrd file. This can be useful if you are on a board
1129 which has a small amount of memory.

1175 Kprobes allows you to trap at almost any kernel address and
1176 execute a callback function. register_kprobe() establishes
1177 a probepoint and specifies the callback. Kprobes is useful
1178 for kernel debugging, non-intrusive instrumentation and testing.
