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

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

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

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

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

1111 config CONSISTENT_START_BOOL
1112 bool "Set custom consistent memory pool address"
1113 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1115 This option allows you to set the base virtual address
1116 of the consistent memory pool. This pool of virtual
1117 memory is used to make consistent memory allocations.
1119 config CONSISTENT_START
1120 hex "Base virtual address of consistent memory pool" if CONSISTENT_START_BOOL
1121 default "0xff100000" if NOT_COHERENT_CACHE
1123 config CONSISTENT_SIZE_BOOL
1124 bool "Set custom consistent memory pool size"
1125 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1127 This option allows you to set the size of the
1128 consistent memory pool. This pool of virtual memory
1129 is used to make consistent memory allocations.
1131 config CONSISTENT_SIZE
1132 hex "Size of consistent memory pool" if CONSISTENT_SIZE_BOOL
1133 default "0x00200000" if NOT_COHERENT_CACHE
1135 config BOOT_LOAD_BOOL
1136 bool "Set the boot link/load address"
1137 depends on ADVANCED_OPTIONS && !PPC_MULTIPLATFORM
1139 This option allows you to set the initial load address of the zImage
1140 or zImage.initrd file. This can be useful if you are on a board
1141 which has a small amount of memory.
1143 Say N here unless you know what you are doing.

1147 default "0x00400000" if 40x || 8xx || 8260

1187 Kprobes allows you to trap at almost any kernel address and
1188 execute a callback function. register_kprobe() establishes
1189 a probepoint and specifies the callback. Kprobes is useful
1190 for kernel debugging, non-intrusive instrumentation and testing.
