CONFIG_FPE_NWFPE: NWFPE math emulation

General informations

The Linux kernel configuration item CONFIG_FPE_NWFPE has multiple definitions:

NWFPE math emulation found in arch/arm/Kconfig

The configuration item CONFIG_FPE_NWFPE:

Help text

Say Y to include the NWFPE floating point emulator in the kernel. This is necessary to run most binaries. Linux does not currently support floating point hardware so you need to say Y here even if your machine has an FPA or floating point co-processor podule.

You may say N here if you are going to load the Acorn FPEmulator early in the bootup.

NWFPE math emulation found in arch/arm26/Kconfig

The configuration item CONFIG_FPE_NWFPE:

Help text

Say Y to include the NWFPE floating point emulator in the kernel. This is necessary to run most binaries. Linux does not currently support floating point hardware so you need to say Y here even if your machine has an FPA or floating point co-processor module.

It is also possible to say M to build the emulator as a module (nwfpe) or indeed to leave it out altogether. However, unless you know what you are doing this can easily render your machine unbootable. Saying Y is the safe option.

You may say N here if you are going to load the Acorn FPEmulator early in the bootup.
