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.

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

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

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

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

781 bool "kexec system call (EXPERIMENTAL)"
782 depends on PPC_MULTIPLATFORM && EXPERIMENTAL
784 kexec is a system call that implements the ability to shutdown your
785 current kernel, and to start another kernel. It is like a reboot
786 but it is independent of the system firmware. And like a reboot
787 you can start any kernel with it, not just Linux.
789 The name comes from the similarity to the exec system call.
791 It is an ongoing process to be certain the hardware in a machine
792 is properly shutdown, so do not be surprised if this code does not
793 initially work for you. It may help to enable device hotplugging
794 support. As of this writing the exact hardware interface is
795 strongly in flux, so no good recommendation can be made.

1121 This option allows you to set the amount of virtual address space
1122 allocated to user tasks. This can be useful in optimizing the
1123 virtual memory layout of the system.

1135 This option allows you to set the base virtual address
1136 of the consistent memory pool. This pool of virtual
1137 memory is used to make consistent memory allocations.

1207 Kprobes allows you to trap at almost any kernel address and
1208 execute a callback function. register_kprobe() establishes
1209 a probepoint and specifies the callback. Kprobes is useful
1210 for kernel debugging, non-intrusive instrumentation and testing.
