  44. There are four types of PowerPC chips supported. The more common
  45. types (601, 603, 604, 740, 750, 7400), the Motorola embedded
  46. versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the IBM
  47. embedded versions (403 and 405) and the POWER3 processor.
  48. (For support for more recent 64-bit processors, set ARCH=powerpc.)
  49. Unless you are building a kernel for one of the embedded processor
  50. systems or a POWER3-based IBM RS/6000, choose 6xx.
  51. Note that the kernel runs in 32-bit mode even on 64-bit chips.
  52. Also note that because the 52xx, 82xx, & 83xx family has a 603e core,
  53. specific support for that chipset is asked later on.

  96. This option enables kernel support for the Altivec extensions to the
  97. PowerPC processor. The kernel currently supports saving and restoring
  98. altivec registers, and turning on the 'altivec enable' bit so user
  99. processes can execute altivec instructions.
  100. This option is only usefully if you have a processor that supports
  101. altivec (G4, otherwise known as 74xx series), but does not have
  102. any affect on a non-altivec cpu (it does, however add code to the
  103. kernel).

  111. supports saving and restoring SPE registers, and turning on the
  112. 'spe enable' bit so user processes can execute SPE instructions.
  113. This option is only useful if you have a processor that supports
  114. SPE (e500, otherwise known as 85xx series), but does not have any
  115. effect on a non-spe cpu (it does, however add code to the kernel).
  116. If in doubt, say Y here.
  117. config TAU
  118. bool "Thermal Management Support"
  119. depends on 6xx && !8260 && !83xx
  120. help
  121. G3 and G4 processors have an on-chip temperature sensor called the
  122. 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
  123. temperature within 2-4 degrees Celsius. This option shows the current
  124. on-die temperature in /proc/cpuinfo if the cpu supports it.
  125. Unfortunately, on some chip revisions, this sensor is very inaccurate
  126. and in some cases, does not work at all, so don't assume the cpu
  127. temp is actually what /proc/cpuinfo says it is.
  128. config TAU_INT
  129. bool "Interrupt driven TAU driver (DANGEROUS)"
  130. depends on TAU
  131. ---help---
  132. The TAU supports an interrupt driven mode which causes an interrupt
  133. whenever the temperature goes out of range. This is the fastest way
  134. to get notified the temp has exceeded a range. With this option off,
  135. a timer is used to re-check the temperature periodically.
  136. However, on some cpus it appears that the TAU interrupt hardware
  137. is buggy and can cause a situation which would lead unexplained hard
  138. lockups.
  139. Unless you are extending the TAU driver, or enjoy kernel/hardware
  140. debugging, leave this option off.
  141. config TAU_AVERAGE
  142. bool "Average high and low temp"
  143. depends on TAU
  144. ---help---
  145. The TAU hardware can compare the temperature to an upper and lower
  146. bound. The default behavior is to show both the upper and lower
  147. bound in /proc/cpuinfo. If the range is large, the temperature is
  148. either changing a lot, or the TAU hardware is broken (likely on some
  149. G4's). If the range is small (around 4 degrees), the temperature is
  150. relatively stable. If you say Y here, a single temperature value,
  151. halfway between the upper and lower bounds, will be reported in
  152. /proc/cpuinfo.
  153. If in doubt, say N here.
  154. config MATH_EMULATION
  155. bool "Math emulation"
  156. depends on 4xx || 8xx || E200 || E500
  157. ---help---
  158. Some PowerPC chips designed for embedded applications do not have
  159. a floating-point unit and therefore do not implement the
  160. floating-point instructions in the PowerPC instruction set. If you
  161. say Y here, the kernel will include code to emulate a floating-point
  162. unit, which will allow programs that use floating-point
  163. instructions to run.
  164. If you have an Apple machine or an IBM RS/6000 or pSeries machine,
  165. or any machine with a 6xx, 7xx or 7xxx series processor, say N
  166. here. Saying Y here will not hurt performance (on any machine) but
  167. will increase the size of the kernel.
  168. config KEXEC
  169. bool "kexec system call (EXPERIMENTAL)"
  170. depends on EXPERIMENTAL
  171. help
  172. kexec is a system call that implements the ability to shutdown your
  173. current kernel, and to start another kernel. It is like a reboot
  174. but it is indepedent of the system firmware. And like a reboot
  175. you can start any kernel with it, not just Linux.
  176. The name comes from the similiarity to the exec system call.
  177. It is an ongoing process to be certain the hardware in a machine
  178. is properly shutdown, so do not be surprised if this code does not
  179. initially work for you. It may help to enable device hotplugging
  180. support. As of this writing the exact hardware interface is
  181. strongly in flux, so no good recommendation can be made.
  182. In the GameCube implementation, kexec allows you to load and
  183. run DOL files, including kernel and homebrew DOLs.

  188. help
  189. Some versions of the PPC601 (the first PowerPC chip) have bugs which
  190. mean that extra synchronization instructions are required near
  191. certain instructions, typically those that make major changes to the
  192. CPU state. These extra instructions reduce performance slightly.
  193. If you say N here, these extra instructions will not be included,
  194. resulting in a kernel which will run faster but may not run at all
  195. on some systems with the PPC601 chip.
  196. If in doubt, say Y here.
