| depends on 6xx && (PPC_PREP || PPC_PMAC) |
| 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. |

| config TAU |
| bool "On-chip CPU temperature sensor support" |
| depends on CLASSIC32 |
| 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 many 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. |
