This makes the kernel a bit faster as no tests - needs to be executed whether a floating-point instruction in the - kernel should be executed or not. - -config ADVANCED - bool "Advanced configuration options" - depends on MMU - ---help--- - This gives you access to some advanced options for the CPU.

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 - really know what you are doing, say N.

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.

This is the core clock - frequency, it may or may not be the same as the external clock - crystal fitted to your board. Some processors have an internal - PLL and can have their frequency programmed at run time, others - use internal dividers.
