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.

321 kernel entry and exit and on transitions within the kernel
322 between system, softirq and hardirq state, so there is a

336 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors

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

746 Cause IO segments sent to a device for DMA to be merged virtually
747 by the IOMMU when they happen to have been allocated contiguously.

766 bool "kexec system call (EXPERIMENTAL)"
767 depends on PPC_MULTIPLATFORM && EXPERIMENTAL
769 kexec is a system call that implements the ability to shutdown your
770 current kernel, and to start another kernel. It is like a reboot
771 but it is independent of the system firmware. And like a reboot
772 you can start any kernel with it, not just Linux.
774 The name comes from the similarity to the exec system call.
776 It is an ongoing process to be certain the hardware in a machine
777 is properly shutdown, so do not be surprised if this code does not
778 initially work for you. It may help to enable device hotplugging

1106 This option allows you to set the amount of virtual address space
1107 allocated to user tasks. This can be useful in optimizing the
1108 virtual memory layout of the system.

1118 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1120 This option allows you to set the base virtual address
1121 of the consistent memory pool. This pool of virtual
1122 memory is used to make consistent memory allocations.

1146 which has a small amount of memory.

1192 Kprobes allows you to trap at almost any kernel address and
1193 execute a callback function. register_kprobe() establishes
1194 a probepoint and specifies the callback. Kprobes is useful
1195 for kernel debugging, non-intrusive instrumentation and testing.
