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

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

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

766 kexec is a system call that implements the ability to shutdown your

768 but it is independent of the system firmware. And like a reboot
769 you can start any kernel with it, not just Linux.
771 The name comes from the similarity to the exec system call.
773 It is an ongoing process to be certain the hardware in a machine
774 is properly shutdown, so do not be surprised if this code does not
775 initially work for you. It may help to enable device hotplugging
776 support. As of this writing the exact hardware interface is

1105 virtual memory layout of the system.

1115 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1117 This option allows you to set the base virtual address
1118 of the consistent memory pool. This pool of virtual
1119 memory is used to make consistent memory allocations.

1129 This option allows you to set the size of the
1130 consistent memory pool. This pool of virtual memory
1131 is used to make consistent memory allocations.

1141 This option allows you to set the initial load address of the zImage
1142 or zImage.initrd file. This can be useful if you are on a board
1143 which has a small amount of memory.

1189 Kprobes allows you to trap at almost any kernel address and
1190 execute a callback function. register_kprobe() establishes
1191 a probepoint and specifies the callback. Kprobes is useful
1192 for kernel debugging, non-intrusive instrumentation and testing.
