CONFIG_M68KFPU_EMU: Math emulation support

General informations

The Linux kernel configuration item CONFIG_M68KFPU_EMU has multiple definitions:

Math emulation support found in arch/m68k/Kconfig.cpu

The configuration item CONFIG_M68KFPU_EMU:

• prompt: Math emulation support
• type: bool
• depends on: ( CONFIG_M68KCLASSIC || CONFIG_SUN3 ) && CONFIG_FPU
• defined in arch/m68k/Kconfig.cpu
• found in Linux kernels: 3.8–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.17, 6.18-rc+HEAD

At some point in the future, this will cause floating-point math instructions to be emulated by the kernel on machines that lack a floating-point math coprocessor. Thrill-seekers and chronically sleep-deprived psychotic hacker types can say Y now, everyone else should probably wait a while.

Math emulation support (EXPERIMENTAL) found in arch/m68k/Kconfig.cpu

The configuration item CONFIG_M68KFPU_EMU:

• prompt: Math emulation support (EXPERIMENTAL)
• type: bool
• depends on: ( CONFIG_MMU ) && ( CONFIG_EXPERIMENTAL )
• defined in arch/m68k/Kconfig.cpu
• found in Linux kernels: 3.2–3.7
