config PPC601_SYNC_FIX

        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.
