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. config CPM2 bool default n help The CPM2 (Communications Processor Module) is a coprocessor on embedded CPUs made by Freescale. Selecting this option means that you wish to build a kernel for a machine with a CPM2 coprocessor on it (826x, 827x, 8560). endmenu
