Thrill-seekers and chronically 304 sleep-deprived psychotic hacker types can say Y now, everyone else 305 should probably wait a while. 306 307config M68KFPU_EMU_EXTRAPREC 308 bool "Math emulation extra precision" 309 depends on M68KFPU_EMU 310 help 311 The fpu uses normally a few bit more during calculations for 312 correct rounding, the emulator can (often) do the same but this 313 extra calculation can cost quite some time, so you can disable 314 it here. The emulator will then "only" calculate with a 64 bit 315 mantissa and round slightly incorrect, what is more then enough 316 for normal usage. 317 318config M68KFPU_EMU_ONLY 319 bool "Math emulation only kernel" 320 depends on M68KFPU_EMU 321 help 322 This option prevents any floating-point instructions from being 323 compiled into the kernel, thereby the kernel doesn't save any 324 floating point context anymore during task switches, so this 325 kernel will only be usable on machines without a floating-point 326 math coprocessor. This makes the kernel a bit faster as no tests 327 needs to be executed whether a floating-point instruction in the 328 kernel should be executed or not. 329 330config ADVANCED 331 bool "Advanced configuration options" 332 ---help--- 333 This gives you access to some advanced options for the CPU. The 334 defaults should be fine for most users, but these options may make 335 it possible for you to improve performance somewhat if you know what 336 you are doing. 337 338 Note that the answer to this question won't directly affect the 339 kernel: saying N will just cause the configurator to skip all 340 the questions about these options. 341 342 Most users should say N to this question. 343 344config RMW_INSNS 345 bool "Use read-modify-write instructions" 346 depends on ADVANCED 347 ---help--- 348 This allows to use certain instructions that work with indivisible 349 read-modify-write bus cycles. While this is faster than the 350 workaround of disabling interrupts, it can conflict with DMA 351 ( = direct memory access) on many Amiga systems, and it is also said 352 to destabilize other machines. It is very likely that this will 353 cause serious problems on any Amiga or Atari Medusa if set. The only 354 configuration where it should work are 68030-based Ataris, where it 355 apparently improves performance. But you've been warned! Unless you 356 really know what you are doing, say N.

Saying Y 375 here will force supervisor (kernel) accesses to use writethrough 376 caching. Writethrough caching means that data is written to memory 377 straight away, so that cache and memory data always agree. 378 Writethrough caching is less efficient, but is needed for some 379 drivers on 68060 based systems where the 68060 bus snooping signal 380 is hardwired on.
