Component Type: kbuild config
Description: Use read-modify-write instructions
More info: 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.
