The Extended Industry Standard Architecture (EISA) bus was
|
|
developed as an open alternative to the IBM MicroChannel bus.
|
|
|
|
The EISA bus provided some of the features of the IBM MicroChannel
|
|
bus while maintaining backward compatibility with cards made for
|
|
the older ISA bus. The EISA bus saw limited use between 1988 and
|
|
1995 when it was made obsolete by the PCI bus.
|
|

Say Y here if you are building a kernel for an EISA-based machine.

Otherwise, say N.

Invalidate maintenance operations: by Physical Address

They are architecturally defined to behave as the execution of a

both performing to the same memory location. This functionality

your machine has an FPA or floating point co-processor podule.

You almost surely want to say N here.

Say Y here to include the FAST floating point emulator in the kernel.
|
|
This is an experimental much faster emulator which now also has full
|
|
precision for the mantissa. It does not support any exceptions.
|
|
It is very simple, and approximately 3-6 times faster than NWFPE.
|
|
|
|
It should be sufficient for most programs. It may be not suitable
|
|
for scientific calculations, but you have to check this for yourself.
|
|
If you do not feel you need a faster FP emulation you should better
|
|
choose NWFPE.
