115 bool "52xx/6xx/7xx/74xx"
119 There are four families of PowerPC chips supported. The more common
120 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
121 versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC
122 embedded versions (403 and 405) and the high end 64 bit Power
123 processors (POWER 3, POWER4, and IBM PPC970 also known as G5).
125 This option is the catch-all for 6xx types, including some of the
126 embedded versions. Unless there is see an option for the specific
127 chip family you are using, you want this option.
129 You do not want this if you are building a kernel for a 64 bit
130 IBM RS/6000 or an Apple G5, choose 6xx.

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

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

322 than one CPU, say Y. Note that the kernel does not currently
323 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors

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

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

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

1123 which has a small amount of memory.

1169 Kprobes allows you to trap at almost any kernel address and
1170 execute a callback function. register_kprobe() establishes
1171 a probepoint and specifies the callback. Kprobes is useful
1172 for kernel debugging, non-intrusive instrumentation and testing.
