  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.

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

 148           supports saving and restoring SPE registers, and turning on the

 150
 151           This option is only usefully if you have a processor that supports
 152           SPE (e500, otherwise known as 85xx series), but does not have any

 160         help
 161           G3 and G4 processors have an on-chip temperature sensor called the
 162           'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
 163           temperature within 2-4 degrees Celsius. This option shows the current
 164           on-die temperature in /proc/cpuinfo if the cpu supports it.
 165
 166           Unfortunately, on some chip revisions, this sensor is very inaccurate
 167           and in some cases, does not work at all, so don't assume the cpu
 168           temp is actually what /proc/cpuinfo says it is.
 169
 170 config TAU_INT
 171         bool "Interrupt driven TAU driver (DANGEROUS)"
 172         depends on TAU
 173         ---help---
 174           The TAU supports an interrupt driven mode which causes an interrupt
 175           whenever the temperature goes out of range. This is the fastest way
 176           to get notified the temp has exceeded a range. With this option off,
 177           a timer is used to re-check the temperature periodically.
 178
 179           However, on some cpus it appears that the TAU interrupt hardware
 180           is buggy and can cause a situation which would lead unexplained hard
 181           lockups.
 182
 183           Unless you are extending the TAU driver, or enjoy kernel/hardware
 184           debugging, leave this option off.
 185

 187         bool "Average high and low temp"
 188         depends on TAU
 189         ---help---
 190           The TAU hardware can compare the temperature to an upper and lower
 191           bound.  The default behavior is to show both the upper and lower
 192           bound in /proc/cpuinfo. If the range is large, the temperature is
 193           either changing a lot, or the TAU hardware is broken (likely on some
 194           G4's). If the range is small (around 4 degrees), the temperature is
 195           relatively stable.  If you say Y here, a single temperature value,
 196           halfway between the upper and lower bounds, will be reported in
 197           /proc/cpuinfo.
 198

 202         bool "Math emulation"
 203         depends on 4xx || 8xx || E500
 204         ---help---
 205           Some PowerPC chips designed for embedded applications do not have
 206           a floating-point unit and therefore do not implement the
 207           floating-point instructions in the PowerPC instruction set.  If you
 208           say Y here, the kernel will include code to emulate a floating-point
 209           unit, which will allow programs that use floating-point
 210           instructions to run.
 211
 212           If you have an Apple machine or an IBM RS/6000 or pSeries machine,
 213           or any machine with a 6xx, 7xx or 7xxx series processor, say N
 214           here.  Saying Y here will not hurt performance (on any machine) but
 215           will increase the size of the kernel.

 231         help
 232           Some versions of the PPC601 (the first PowerPC chip) have bugs which
 233           mean that extra synchronization instructions are required near
 234           certain instructions, typically those that make major changes to the
 235           CPU state.  These extra instructions reduce performance slightly.
 236           If you say N here, these extra instructions will not be included,
 237           resulting in a kernel which will run faster but may not run at all
 238           on some systems with the PPC601 chip.
