128 bool "52xx/6xx/7xx/74xx"
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

327 accounting. This is done by reading a CPU counter on each
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
331 stolen time on logically-partitioned systems running on

340 This enables support for systems with more than one CPU. If you have
341 a system with only one CPU, say N. If you have a system with more
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
347 If you say N here, the kernel will run on single and multiprocessor
348 machines, but will use only one CPU of a multiprocessor machine. If

595 depends on 6xx && (PPC_PREP || PPC_PMAC)
597 Some versions of the PPC601 (the first PowerPC chip) have bugs which
598 mean that extra synchronization instructions are required near
599 certain instructions, typically those that make major changes to the
600 CPU state. These extra instructions reduce performance slightly.
601 If you say N here, these extra instructions will not be included,
602 resulting in a kernel which will run faster but may not run at all
603 on some systems with the PPC601 chip.
605 If in doubt, say Y here.
608 bool "On-chip CPU temperature sensor support"
611 G3 and G4 processors have an on-chip temperature sensor called the
612 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
613 temperature within 2-4 degrees Celsius. This option shows the current
614 on-die temperature in /proc/cpuinfo if the cpu supports it.
616 Unfortunately, on some chip revisions, this sensor is very inaccurate
617 and in many cases, does not work at all, so don't assume the cpu
618 temp is actually what /proc/cpuinfo says it is.
621 bool "Interrupt driven TAU driver (DANGEROUS)"
624 The TAU supports an interrupt driven mode which causes an interrupt
625 whenever the temperature goes out of range. This is the fastest way
626 to get notified the temp has exceeded a range. With this option off,
627 a timer is used to re-check the temperature periodically.
629 However, on some cpus it appears that the TAU interrupt hardware
630 is buggy and can cause a situation which would lead unexplained hard
633 Unless you are extending the TAU driver, or enjoy kernel/hardware
634 debugging, leave this option off.
637 bool "Average high and low temp"
640 The TAU hardware can compare the temperature to an upper and lower
641 bound. The default behavior is to show both the upper and lower
642 bound in /proc/cpuinfo. If the range is large, the temperature is
643 either changing a lot, or the TAU hardware is broken (likely on some
644 G4's). If the range is small (around 4 degrees), the temperature is
645 relatively stable. If you say Y here, a single temperature value,
646 halfway between the upper and lower bounds, will be reported in
649 If in doubt, say N here.

693 bool "Enable IOMMU virtual merging (EXPERIMENTAL)"
694 depends on EXPERIMENTAL && PPC64
697 Cause IO segments sent to a device for DMA to be merged virtually
698 by the IOMMU when they happen to have been allocated contiguously.
699 This doesn't add pressure to the IOMMU allocator. However, some

720 kexec is a system call that implements the ability to shutdown your

722 but it is independent of the system firmware. And like a reboot
723 you can start any kernel with it, not just Linux.
725 The name comes from the similarity to the exec system call.
727 It is an ongoing process to be certain the hardware in a machine
728 is properly shutdown, so do not be surprised if this code does not
729 initially work for you. It may help to enable device hotplugging

1086 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1088 This option allows you to set the size of the
1089 consistent memory pool. This pool of virtual memory
1090 is used to make consistent memory allocations.

1100 This option allows you to set the initial load address of the zImage
1101 or zImage.initrd file. This can be useful if you are on a board
1102 which has a small amount of memory.

1148 Kprobes allows you to trap at almost any kernel address and
1149 execute a callback function. register_kprobe() establishes
1150 a probepoint and specifies the callback. Kprobes is useful
1151 for kernel debugging, non-intrusive instrumentation and testing.
1152 If in doubt, say "N".
