The fpu uses normally a few bit more during calculations for

correct rounding, the emulator can (often) do the same but this

extra calculation can cost quite some time, so you can disable

it here. The emulator will then "only" calculate with a 64 bit

mantissa and round slightly incorrect, what is more than enough

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
|
|
math coprocessor. 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.

Note that the answer to this question won't directly affect the
|
|
kernel: saying N will just cause the configurator to skip all
|
|
the questions about these options.
|
|
|
|
Most users should say N to this question.

This allows to use certain instructions that work with indivisible
|
|
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
|
|
really know what you are doing, say N. Try Y only if you're quite
|
|
adventurous.

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.

Define the CPU clock frequency in use. 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. In general the kernel won't setup a PLL
|

if it is fitted (there are some exceptions). This value will be

specific to the exact CPU that you are using.
