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

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

 151           supports saving and restoring SPE registers, and turning on the
 152           'spe enable' bit so user processes can execute SPE instructions.
 153
 154           This option is only useful if you have a processor that supports
 155           SPE (e500, otherwise known as 85xx series), but does not have any
 156           effect on a non-spe cpu (it does, however add code to the kernel).

 161         bool "Thermal Management Support"
 162         depends on 6xx && !8260 && !83xx
 163         help
 164           G3 and G4 processors have an on-chip temperature sensor called the
 165           'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
 166           temperature within 2-4 degrees Celsius. This option shows the current
 167           on-die temperature in /proc/cpuinfo if the cpu supports it.
 168
 169           Unfortunately, on some chip revisions, this sensor is very inaccurate
 170           and in some cases, does not work at all, so don't assume the cpu
 171           temp is actually what /proc/cpuinfo says it is.
 172
 173 config TAU_INT
 174         bool "Interrupt driven TAU driver (DANGEROUS)"
 175         depends on TAU
 176         ---help---
 177           The TAU supports an interrupt driven mode which causes an interrupt
 178           whenever the temperature goes out of range. This is the fastest way
 179           to get notified the temp has exceeded a range. With this option off,
 180           a timer is used to re-check the temperature periodically.
 181
 182           However, on some cpus it appears that the TAU interrupt hardware
 183           is buggy and can cause a situation which would lead unexplained hard
 184           lockups.
 185
 186           Unless you are extending the TAU driver, or enjoy kernel/hardware
 187           debugging, leave this option off.
 188
 189 config TAU_AVERAGE
 190         bool "Average high and low temp"
 191         depends on TAU
 192         ---help---
 193           The TAU hardware can compare the temperature to an upper and lower
 194           bound.  The default behavior is to show both the upper and lower
 195           bound in /proc/cpuinfo. If the range is large, the temperature is
 196           either changing a lot, or the TAU hardware is broken (likely on some
 197           G4's). If the range is small (around 4 degrees), the temperature is
 198           relatively stable.  If you say Y here, a single temperature value,
 199           halfway between the upper and lower bounds, will be reported in
 200           /proc/cpuinfo.
 201

 204 config MATH_EMULATION

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

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

1258           This option allows you to set the base address of the kernel virtual
1259           area used to map high memory pages.  This can be useful in
1260           optimizing the layout of kernel virtual memory.

1272           This option allows you to set the maximum amount of memory which
1273           will be used as "low memory", that is, memory which the kernel can
1274           access directly, without having to set up a kernel virtual mapping.
1275           This can be useful in optimizing the layout of kernel virtual
