  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.

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

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

 148
 149           This option is only usefully if you have a processor that supports
 150           SPE (e500, otherwise known as 85xx series), but does not have any

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

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

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

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