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
323 small performance impact. This also enables accounting of

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

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

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

760 bool "kexec system call (EXPERIMENTAL)"

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

1107 hex "Size of user task space" if TASK_SIZE_BOOL
1108 default "0x80000000"
1110 config CONSISTENT_START_BOOL
1111 bool "Set custom consistent memory pool address"
1112 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1114 This option allows you to set the base virtual address
1115 of the consistent memory pool. This pool of virtual
1116 memory is used to make consistent memory allocations.
1118 config CONSISTENT_START
1119 hex "Base virtual address of consistent memory pool" if CONSISTENT_START_BOOL
1120 default "0xff100000" if NOT_COHERENT_CACHE
1122 config CONSISTENT_SIZE_BOOL
1123 bool "Set custom consistent memory pool size"
1124 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1126 This option allows you to set the size of the
1127 consistent memory pool. This pool of virtual memory
1128 is used to make consistent memory allocations.
1130 config CONSISTENT_SIZE
1131 hex "Size of consistent memory pool" if CONSISTENT_SIZE_BOOL
1132 default "0x00200000" if NOT_COHERENT_CACHE
1134 config BOOT_LOAD_BOOL
1135 bool "Set the boot link/load address"
1136 depends on ADVANCED_OPTIONS && !PPC_MULTIPLATFORM
1138 This option allows you to set the initial load address of the zImage
1139 or zImage.initrd file. This can be useful if you are on a board
1140 which has a small amount of memory.
1142 Say N here unless you know what you are doing.
1145 hex "Link/load address for booting" if BOOT_LOAD_BOOL
1146 default "0x00400000" if 40x || 8xx || 8260

1186 Kprobes allows you to trap at almost any kernel address and
1187 execute a callback function. register_kprobe() establishes
1188 a probepoint and specifies the callback. Kprobes is useful
1189 for kernel debugging, non-intrusive instrumentation and testing.
