Thrill-seekers and chronically 312 sleep-deprived psychotic hacker types can say Y now, everyone else 313 should probably wait a while. 314 315config M68KFPU_EMU_EXTRAPREC 316 bool "Math emulation extra precision" 317 depends on M68KFPU_EMU 318 help 319 The fpu uses normally a few bit more during calculations for 320 correct rounding, the emulator can (often) do the same but this 321 extra calculation can cost quite some time, so you can disable 322 it here. The emulator will then "only" calculate with a 64 bit 323 mantissa and round slightly incorrect, what is more then enough 324 for normal usage. 325 326config M68KFPU_EMU_ONLY 327 bool "Math emulation only kernel" 328 depends on M68KFPU_EMU 329 help 330 This option prevents any floating-point instructions from being 331 compiled into the kernel, thereby the kernel doesn't save any 332 floating point context anymore during task switches, so this 333 kernel will only be usable on machines without a floating-point 334 math coprocessor. This makes the kernel a bit faster as no tests 335 needs to be executed whether a floating-point instruction in the 336 kernel should be executed or not. 337 338config ADVANCED 339 bool "Advanced configuration options" 340 ---help--- 341 This gives you access to some advanced options for the CPU. The 342 defaults should be fine for most users, but these options may make 343 it possible for you to improve performance somewhat if you know what 344 you are doing. 345 346 Note that the answer to this question won't directly affect the 347 kernel: saying N will just cause the configurator to skip all 348 the questions about these options. 349 350 Most users should say N to this question. 351 352config RMW_INSNS 353 bool "Use read-modify-write instructions" 354 depends on ADVANCED 355 ---help--- 356 This allows to use certain instructions that work with indivisible 357 read-modify-write bus cycles. While this is faster than the 358 workaround of disabling interrupts, it can conflict with DMA 359 ( = direct memory access) on many Amiga systems, and it is also said 360 to destabilize other machines. It is very likely that this will 361 cause serious problems on any Amiga or Atari Medusa if set. The only 362 configuration where it should work are 68030-based Ataris, where it 363 apparently improves performance. But you've been warned! Unless you 364 really know what you are doing, say N.

Saying Y 383 here will force supervisor (kernel) accesses to use writethrough 384 caching. Writethrough caching means that data is written to memory 385 straight away, so that cache and memory data always agree. 386 Writethrough caching is less efficient, but is needed for some 387 drivers on 68060 based systems where the 68060 bus snooping signal 388 is hardwired on.
