  65. There are four types of PowerPC chips supported. The more common
  66. types (601, 603, 604, 740, 750, 7400), the older Freescale
  67. (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
  68. 52xx, 82xx), the IBM embedded versions (403 and 405) and
  69. the Book E embedded processors from IBM (44x) and Freescale (85xx).
  70. For support for 64-bit processors, set ARCH=powerpc.
  71. Unless you are building a kernel for one of the embedded processor
  72. systems, choose 6xx.
  73. Also note that because the 52xx, 82xx family have a 603e
  74. core, specific support for that chipset is asked later on.

  110. ---help---
  111. This option enables kernel support for the Altivec extensions to the
  112. PowerPC processor. The kernel currently supports saving and restoring
  113. altivec registers, and turning on the 'altivec enable' bit so user
  114. processes can execute altivec instructions.
  115. This option is only usefully if you have a processor that supports
  116. altivec (G4, otherwise known as 74xx series), but does not have
  117. any affect on a non-altivec cpu (it does, however add code to the
  118. kernel).
  119. If in doubt, say Y here.
  120. config TAU
  121. bool "Thermal Management Support"
  122. depends on 6xx && !8260
  123. help
  124. G3 and G4 processors have an on-chip temperature sensor called the
  125. 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
  126. temperature within 2-4 degrees Celsius. This option shows the current
  127. on-die temperature in /proc/cpuinfo if the cpu supports it.
  128. Unfortunately, on some chip revisions, this sensor is very inaccurate
  129. and in some cases, does not work at all, so don't assume the cpu
  130. temp is actually what /proc/cpuinfo says it is.
  131. config TAU_INT
  132. bool "Interrupt driven TAU driver (DANGEROUS)"
  133. depends on TAU
  134. ---help---
  135. The TAU supports an interrupt driven mode which causes an interrupt
  136. whenever the temperature goes out of range. This is the fastest way
  137. to get notified the temp has exceeded a range. With this option off,
  138. a timer is used to re-check the temperature periodically.
  139. However, on some cpus it appears that the TAU interrupt hardware
  140. is buggy and can cause a situation which would lead unexplained hard
  141. lockups.
  142. Unless you are extending the TAU driver, or enjoy kernel/hardware
  143. debugging, leave this option off.
  144. config TAU_AVERAGE
  145. bool "Average high and low temp"
  146. depends on TAU
  147. ---help---
  148. The TAU hardware can compare the temperature to an upper and lower
  149. bound. The default behavior is to show both the upper and lower
  150. bound in /proc/cpuinfo. If the range is large, the temperature is
  151. either changing a lot, or the TAU hardware is broken (likely on some
  152. G4's). If the range is small (around 4 degrees), the temperature is
  153. relatively stable. If you say Y here, a single temperature value,
  154. halfway between the upper and lower bounds, will be reported in
  155. /proc/cpuinfo.
  156. If in doubt, say N here.
  157. config MATH_EMULATION
  158. bool "Math emulation"
  159. depends on 4xx || 8xx
  160. ---help---
  161. Some PowerPC chips designed for embedded applications do not have
  162. a floating-point unit and therefore do not implement the
  163. floating-point instructions in the PowerPC instruction set. If you
  164. say Y here, the kernel will include code to emulate a floating-point
  165. unit, which will allow programs that use floating-point
  166. instructions to run.
  167. If you have an Apple machine or an IBM RS/6000 or pSeries machine,
  168. or any machine with a 6xx, 7xx or 7xxx series processor, say N
  169. here. Saying Y here will not hurt performance (on any machine) but
  170. will increase the size of the kernel.
  171. config KEXEC
  172. bool "kexec system call (EXPERIMENTAL)"
  173. depends on EXPERIMENTAL
  174. help
  175. kexec is a system call that implements the ability to shutdown your
  176. current kernel, and to start another kernel. It is like a reboot
  177. but it is independent of the system firmware. And like a reboot
  178. you can start any kernel with it, not just Linux.
  179. The name comes from the similarity to the exec system call.
  180. It is an ongoing process to be certain the hardware in a machine
  181. is properly shutdown, so do not be surprised if this code does not
  182. initially work for you. It may help to enable device hotplugging
  183. support. As of this writing the exact hardware interface is
  184. strongly in flux, so no good recommendation can be made.
  185. In the GameCube implementation, kexec allows you to load and
  186. run DOL files, including kernel and homebrew DOLs.

  189. bool "Workarounds for PPC601 bugs"
  190. depends on 6xx && PPC_PREP
  191. help
  192. Some versions of the PPC601 (the first PowerPC chip) have bugs which
  193. mean that extra synchronization instructions are required near
  194. certain instructions, typically those that make major changes to the
  195. CPU state. These extra instructions reduce performance slightly.
  196. If you say N here, these extra instructions will not be included,
  197. resulting in a kernel which will run faster but may not run at all
  198. on some systems with the PPC601 chip.
  199. If in doubt, say Y here.
