  66           There are four types of PowerPC chips supported.  The more common
  67           types (601, 603, 604, 740, 750, 7400), the Motorola embedded
  68           versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the IBM embedded
  69           versions (403 and 405) and the high end 64 bit Power processors
  70           (POWER 3, POWER4, and IBM 970 also known as G5)
  71           Unless you are building a kernel for one of the embedded processor
  72           systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.
  73           Note that the kernel runs in 32-bit mode even on 64-bit chips.
  74           Also note that because the 52xx, 82xx, & 83xx family has a 603e core,
  75           specific support for that chipset is asked later on.

 136           This option enables kernel support for the Altivec extensions to the
 137           PowerPC processor. The kernel currently supports saving and restoring
 138           altivec registers, and turning on the 'altivec enable' bit so user
 139           processes can execute altivec instructions.
 140
 141           This option is only usefully if you have a processor that supports
 142           altivec (G4, otherwise known as 74xx series), but does not have
 143           any affect on a non-altivec cpu (it does, however add code to the

 154           supports saving and restoring SPE registers, and turning on the
 155           'spe enable' bit so user processes can execute SPE instructions.
 156
 157           This option is only useful if you have a processor that supports
 158           SPE (e500, otherwise known as 85xx series), but does not have any

 164         bool "Thermal Management Support"

 166         help
 167           G3 and G4 processors have an on-chip temperature sensor called the
 168           'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
 169           temperature within 2-4 degrees Celsius. This option shows the current
 170           on-die temperature in /proc/cpuinfo if the cpu supports it.
 171
 172           Unfortunately, on some chip revisions, this sensor is very inaccurate
 173           and in some cases, does not work at all, so don't assume the cpu
 174           temp is actually what /proc/cpuinfo says it is.
 175
 176 config TAU_INT
 177         bool "Interrupt driven TAU driver (DANGEROUS)"
 178         depends on TAU
 179         ---help---
 180           The TAU supports an interrupt driven mode which causes an interrupt
 181           whenever the temperature goes out of range. This is the fastest way
 182           to get notified the temp has exceeded a range. With this option off,
 183           a timer is used to re-check the temperature periodically.
 184
 185           However, on some cpus it appears that the TAU interrupt hardware
 186           is buggy and can cause a situation which would lead unexplained hard
 187           lockups.
 188
 189           Unless you are extending the TAU driver, or enjoy kernel/hardware
 190           debugging, leave this option off.
 191
 192 config TAU_AVERAGE
 193         bool "Average high and low temp"
 194         depends on TAU
 195         ---help---
 196           The TAU hardware can compare the temperature to an upper and lower
 197           bound.  The default behavior is to show both the upper and lower
 198           bound in /proc/cpuinfo. If the range is large, the temperature is
 199           either changing a lot, or the TAU hardware is broken (likely on some
 200           G4's). If the range is small (around 4 degrees), the temperature is
 201           relatively stable.  If you say Y here, a single temperature value,
 202           halfway between the upper and lower bounds, will be reported in
 203           /proc/cpuinfo.
 204

 207 config MATH_EMULATION

 209         depends on 4xx || 8xx || E200 || E500
 210         ---help---
 211           Some PowerPC chips designed for embedded applications do not have
 212           a floating-point unit and therefore do not implement the
 213           floating-point instructions in the PowerPC instruction set.  If you
 214           say Y here, the kernel will include code to emulate a floating-point
 215           unit, which will allow programs that use floating-point
 216           instructions to run.
 217
 218           If you have an Apple machine or an IBM RS/6000 or pSeries machine,
 219           or any machine with a 6xx, 7xx or 7xxx series processor, say N
 220           here.  Saying Y here will not hurt performance (on any machine) but
 221           will increase the size of the kernel.
 222
 223 config KEXEC
 224         bool "kexec system call (EXPERIMENTAL)"
 225         depends on EXPERIMENTAL
 226         help
 227           kexec is a system call that implements the ability to shutdown your
 228           current kernel, and to start another kernel.  It is like a reboot
 229           but it is indepedent of the system firmware.   And like a reboot
 230           you can start any kernel with it, not just Linux.
 231
 232           The name comes from the similiarity to the exec system call.
 233
 234           It is an ongoing process to be certain the hardware in a machine
 235           is properly shutdown, so do not be surprised if this code does not
 236           initially work for you.  It may help to enable device hotplugging
 237           support.  As of this writing the exact hardware interface is
 238           strongly in flux, so no good recommendation can be made.
 239
 240           In the GameCube implementation, kexec allows you to load and
 241           run DOL files, including kernel and homebrew DOLs.

 257         help
 258           Some versions of the PPC601 (the first PowerPC chip) have bugs which
 259           mean that extra synchronization instructions are required near
 260           certain instructions, typically those that make major changes to the
 261           CPU state.  These extra instructions reduce performance slightly.
 262           If you say N here, these extra instructions will not be included,
 263           resulting in a kernel which will run faster but may not run at all
 264           on some systems with the PPC601 chip.
