- The fpu uses normally a few bit more during calculations for

-
-config M68KFPU_EMU_ONLY
- bool "Math emulation only kernel"
- depends on M68KFPU_EMU
- help
- This option prevents any floating-point instructions from being
- compiled into the kernel, thereby the kernel doesn't save any
- floating point context anymore during task switches, so this
- kernel will only be usable on machines without a floating-point

- read-modify-write bus cycles. While this is faster than the
- workaround of disabling interrupts, it can conflict with DMA
- ( = direct memory access) on many Amiga systems, and it is also said
- to destabilize other machines. It is very likely that this will
- cause serious problems on any Amiga or Atari Medusa if set. The only
- configuration where it should work are 68030-based Ataris, where it
- apparently improves performance. But you've been warned! Unless you

-config 060_WRITETHROUGH
- bool "Use write-through caching for 68060 supervisor accesses"
- depends on ADVANCED && M68060
- ---help---
- The 68060 generally uses copyback caching of recently accessed data.
- Copyback caching means that memory writes will be held in an on-chip
- cache and only written back to memory some time later. Saying Y
- here will force supervisor (kernel) accesses to use writethrough
- caching. Writethrough caching means that data is written to memory
- straight away, so that cache and memory data always agree.
- Writethrough caching is less efficient, but is needed for some
- drivers on 68060 based systems where the 68060 bus snooping signal
- is hardwired on. The 53c710 SCSI driver is known to suffer from
- this problem.
