CONFIG_PPC601_SYNC_FIX: Workarounds for PPC601 bugs

General informations

The Linux kernel configuration item CONFIG_PPC601_SYNC_FIX has multiple definitions:

Workarounds for PPC601 bugs found in arch/powerpc/Kconfig

The configuration item CONFIG_PPC601_SYNC_FIX:

Help text

Some versions of the PPC601 (the first PowerPC chip) have bugs which mean that extra synchronization instructions are required near certain instructions, typically those that make major changes to the CPU state. These extra instructions reduce performance slightly. If you say N here, these extra instructions will not be included, resulting in a kernel which will run faster but may not run at all on some systems with the PPC601 chip.

If in doubt, say Y here.
