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

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

320 accounting. This is done by reading a CPU counter on each
321 kernel entry and exit and on transitions within the kernel
322 between system, softirq and hardirq state, so there is a
323 small performance impact. This also enables accounting of

333 This enables support for systems with more than one CPU. If you have
334 a system with only one CPU, say N. If you have a system with more
335 than one CPU, say Y. Note that the kernel does not currently
336 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors

634 depends on 6xx && (PPC_PREP || PPC_PMAC)
636 Some versions of the PPC601 (the first PowerPC chip) have bugs which
637 mean that extra synchronization instructions are required near
638 certain instructions, typically those that make major changes to the
639 CPU state. These extra instructions reduce performance slightly.
640 If you say N here, these extra instructions will not be included,
641 resulting in a kernel which will run faster but may not run at all
642 on some systems with the PPC601 chip.
644 If in doubt, say Y here.
647 bool "On-chip CPU temperature sensor support"
650 G3 and G4 processors have an on-chip temperature sensor called the
651 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
652 temperature within 2-4 degrees Celsius. This option shows the current
653 on-die temperature in /proc/cpuinfo if the cpu supports it.
655 Unfortunately, on some chip revisions, this sensor is very inaccurate
656 and in many cases, does not work at all, so don't assume the cpu
657 temp is actually what /proc/cpuinfo says it is.
660 bool "Interrupt driven TAU driver (DANGEROUS)"
663 The TAU supports an interrupt driven mode which causes an interrupt
664 whenever the temperature goes out of range. This is the fastest way
665 to get notified the temp has exceeded a range. With this option off,
666 a timer is used to re-check the temperature periodically.
668 However, on some cpus it appears that the TAU interrupt hardware
669 is buggy and can cause a situation which would lead unexplained hard
672 Unless you are extending the TAU driver, or enjoy kernel/hardware
673 debugging, leave this option off.
676 bool "Average high and low temp"
679 The TAU hardware can compare the temperature to an upper and lower
680 bound. The default behavior is to show both the upper and lower
681 bound in /proc/cpuinfo. If the range is large, the temperature is
682 either changing a lot, or the TAU hardware is broken (likely on some
683 G4's). If the range is small (around 4 degrees), the temperature is
684 relatively stable. If you say Y here, a single temperature value,
685 halfway between the upper and lower bounds, will be reported in
688 If in doubt, say N here.

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

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

1111 This option allows you to set the base virtual address
1112 of the consistent memory pool. This pool of virtual
1113 memory is used to make consistent memory allocations.

1137 which has a small amount of memory.

1183 Kprobes allows you to trap at almost any kernel address and
1184 execute a callback function. register_kprobe() establishes
1185 a probepoint and specifies the callback. Kprobes is useful
1186 for kernel debugging, non-intrusive instrumentation and testing.
