| There are four types of PowerPC chips supported. The more common |

| (formerly Motorola) embedded versions (821, 823, 850, 855, 860, |

| ---help--- |
| This option enables kernel support for the Altivec extensions to the |
| PowerPC processor. The kernel currently supports saving and restoring |
| altivec registers, and turning on the 'altivec enable' bit so user |
| processes can execute altivec instructions. |
| |
| This option is only usefully if you have a processor that supports |
| altivec (G4, otherwise known as 74xx series), but does not have |
| any affect on a non-altivec cpu (it does, however add code to the |
| kernel). |
| |
| If in doubt, say Y here. |
| |
| config TAU |
| bool "Thermal Management Support" |
| depends on 6xx && !8260 |
| help |
| G3 and G4 processors have an on-chip temperature sensor called the |
| 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die |
| temperature within 2-4 degrees Celsius. This option shows the current |
| on-die temperature in /proc/cpuinfo if the cpu supports it. |
| |
| Unfortunately, on some chip revisions, this sensor is very inaccurate |
| and in some cases, does not work at all, so don't assume the cpu |
| temp is actually what /proc/cpuinfo says it is. |
| |
| config TAU_INT |
| bool "Interrupt driven TAU driver (DANGEROUS)" |
| depends on TAU |
| ---help--- |
| The TAU supports an interrupt driven mode which causes an interrupt |
| whenever the temperature goes out of range. This is the fastest way |
| to get notified the temp has exceeded a range. With this option off, |
| a timer is used to re-check the temperature periodically. |
| |
| However, on some cpus it appears that the TAU interrupt hardware |
| is buggy and can cause a situation which would lead unexplained hard |
| lockups. |
| |
| Unless you are extending the TAU driver, or enjoy kernel/hardware |
| debugging, leave this option off. |
| |
| config TAU_AVERAGE |
| bool "Average high and low temp" |
| depends on TAU |
| ---help--- |
| The TAU hardware can compare the temperature to an upper and lower |
| bound. The default behavior is to show both the upper and lower |
| bound in /proc/cpuinfo. If the range is large, the temperature is |
| either changing a lot, or the TAU hardware is broken (likely on some |
| G4's). If the range is small (around 4 degrees), the temperature is |
| relatively stable. If you say Y here, a single temperature value, |
| halfway between the upper and lower bounds, will be reported in |
| /proc/cpuinfo. |
| |
| If in doubt, say N here. |
| |
| config MATH_EMULATION |
| bool "Math emulation" |
| depends on 4xx || 8xx |
| ---help--- |
| Some PowerPC chips designed for embedded applications do not have |
| a floating-point unit and therefore do not implement the |
| floating-point instructions in the PowerPC instruction set. If you |
| say Y here, the kernel will include code to emulate a floating-point |
| unit, which will allow programs that use floating-point |
| instructions to run. |
| |
| If you have an Apple machine or an IBM RS/6000 or pSeries machine, |
| or any machine with a 6xx, 7xx or 7xxx series processor, say N |
| here. Saying Y here will not hurt performance (on any machine) but |
| will increase the size of the kernel. |
| |
| config KEXEC |
| bool "kexec system call (EXPERIMENTAL)" |
| depends on EXPERIMENTAL |
| help |
| kexec is a system call that implements the ability to shutdown your |
| current kernel, and to start another kernel. It is like a reboot |
| but it is independent of the system firmware. And like a reboot |
| you can start any kernel with it, not just Linux. |
| |
| The name comes from the similarity to the exec system call. |
| |
| It is an ongoing process to be certain the hardware in a machine |
| is properly shutdown, so do not be surprised if this code does not |
| initially work for you. It may help to enable device hotplugging |
| support. As of this writing the exact hardware interface is |
| strongly in flux, so no good recommendation can be made. |
| |
| In the GameCube implementation, kexec allows you to load and |
| run DOL files, including kernel and homebrew DOLs. |

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