Thrill-seekers and chronically 302 sleep-deprived psychotic hacker types can say Y now, everyone else 303 should probably wait a while. 304 305config M68KFPU_EMU_EXTRAPREC 306 bool "Math emulation extra precision" 307 depends on M68KFPU_EMU 308 help 309 The fpu uses normally a few bit more during calculations for 310 correct rounding, the emulator can (often) do the same but this 311 extra calculation can cost quite some time, so you can disable 312 it here. The emulator will then "only" calculate with a 64 bit 313 mantissa and round slightly incorrect, what is more then enough 314 for normal usage. 315 316config M68KFPU_EMU_ONLY 317 bool "Math emulation only kernel" 318 depends on M68KFPU_EMU 319 help 320 This option prevents any floating-point instructions from being 321 compiled into the kernel, thereby the kernel doesn't save any 322 floating point context anymore during task switches, so this 323 kernel will only be usable on machines without a floating-point 324 math coprocessor. This makes the kernel a bit faster as no tests 325 needs to be executed whether a floating-point instruction in the 326 kernel should be executed or not. 327 328config ADVANCED 329 bool "Advanced configuration options" 330 ---help--- 331 This gives you access to some advanced options for the CPU. The 332 defaults should be fine for most users, but these options may make 333 it possible for you to improve performance somewhat if you know what 334 you are doing. 335 336 Note that the answer to this question won't directly affect the 337 kernel: saying N will just cause the configurator to skip all 338 the questions about these options. 339 340 Most users should say N to this question. 341 342config RMW_INSNS 343 bool "Use read-modify-write instructions" 344 depends on ADVANCED 345 ---help--- 346 This allows to use certain instructions that work with indivisible 347 read-modify-write bus cycles. While this is faster than the 348 workaround of disabling interrupts, it can conflict with DMA 349 ( = direct memory access) on many Amiga systems, and it is also said 350 to destabilize other machines. It is very likely that this will 351 cause serious problems on any Amiga or Atari Medusa if set. The only 352 configuration where it should work are 68030-based Ataris, where it 353 apparently improves performance. But you've been warned! Unless you 354 really know what you are doing, say N.

Saying Y 372 here will force supervisor (kernel) accesses to use writethrough 373 caching. Writethrough caching means that data is written to memory 374 straight away, so that cache and memory data always agree. 375 Writethrough caching is less efficient, but is needed for some 376 drivers on 68060 based systems where the 68060 bus snooping signal 377 is hardwired on.
