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.

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

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

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

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

1119 This option allows you to set the amount of virtual address space
1120 allocated to user tasks. This can be useful in optimizing the
1121 virtual memory layout of the system.

1133 This option allows you to set the base virtual address
1134 of the consistent memory pool. This pool of virtual
1135 memory is used to make consistent memory allocations.

1205 Kprobes allows you to trap at almost any kernel address and
1206 execute a callback function. register_kprobe() establishes
1207 a probepoint and specifies the callback. Kprobes is useful
1208 for kernel debugging, non-intrusive instrumentation and testing.
