  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.

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

 150           supports saving and restoring SPE registers, and turning on the
 151           'spe enable' bit so user processes can execute SPE instructions.
 152
 153           This option is only useful if you have a processor that supports
 154           SPE (e500, otherwise known as 85xx series), but does not have any

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

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

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