Otherwise, say N.

Thrill-seekers and chronically 309 sleep-deprived psychotic hacker types can say Y now, everyone else 310 should probably wait a while. 311 312config M68KFPU_EMU_EXTRAPREC 313 bool "Math emulation extra precision" 314 depends on M68KFPU_EMU 315 help 316 The fpu uses normally a few bit more during calculations for 317 correct rounding, the emulator can (often) do the same but this 318 extra calculation can cost quite some time, so you can disable 319 it here. The emulator will then "only" calculate with a 64 bit 320 mantissa and round slightly incorrect, what is more then enough 321 for normal usage. 322 323config M68KFPU_EMU_ONLY 324 bool "Math emulation only kernel" 325 depends on M68KFPU_EMU 326 help 327 This option prevents any floating-point instructions from being 328 compiled into the kernel, thereby the kernel doesn't save any 329 floating point context anymore during task switches, so this 330 kernel will only be usable on machines without a floating-point 331 math coprocessor. This makes the kernel a bit faster as no tests 332 needs to be executed whether a floating-point instruction in the 333 kernel should be executed or not. 334 335config ADVANCED 336 bool "Advanced configuration options" 337 ---help--- 338 This gives you access to some advanced options for the CPU. The 339 defaults should be fine for most users, but these options may make 340 it possible for you to improve performance somewhat if you know what 341 you are doing. 342 343 Note that the answer to this question won't directly affect the 344 kernel: saying N will just cause the configurator to skip all 345 the questions about these options. 346 347 Most users should say N to this question. 348 349config RMW_INSNS 350 bool "Use read-modify-write instructions" 351 depends on ADVANCED 352 ---help--- 353 This allows to use certain instructions that work with indivisible 354 read-modify-write bus cycles. While this is faster than the 355 workaround of disabling interrupts, it can conflict with DMA 356 ( = direct memory access) on many Amiga systems, and it is also said 357 to destabilize other machines. It is very likely that this will 358 cause serious problems on any Amiga or Atari Medusa if set. The only 359 configuration where it should work are 68030-based Ataris, where it 360 apparently improves performance. But you've been warned! Unless you 361 really know what you are doing, say N.

Saying Y 380 here will force supervisor (kernel) accesses to use writethrough 381 caching. Writethrough caching means that data is written to memory 382 straight away, so that cache and memory data always agree. 383 Writethrough caching is less efficient, but is needed for some 384 drivers on 68060 based systems where the 68060 bus snooping signal 385 is hardwired on. The 53c710 SCSI driver is known to suffer from 386 this problem. 387 388config ARCH_DISCONTIGMEM_ENABLE 389 def_bool !SINGLE_MEMORY_CHUNK 390 391config NODES_SHIFT 392 int 393 default "3" 394 depends on !SINGLE_MEMORY_CHUNK 395 396source "mm/Kconfig" 397 398endmenu 399 400menu "General setup" 401 402source "fs/Kconfig.binfmt" 403 404config ZORRO 405 bool "Amiga Zorro (AutoConfig) bus support" 406 depends on AMIGA 407 help 408 This enables support for the Zorro bus in the Amiga.

Note that even 411 expansion cards that do not fit in the Zorro slots but fit in e.g. 412 the CPU slot may fall in this category, so you have to say Y to let 413 Linux use these. 414 415config AMIGA_PCMCIA 416 bool "Amiga 1200/600 PCMCIA support (EXPERIMENTAL)" 417 depends on AMIGA && EXPERIMENTAL 418 help 419 Include support in the kernel for pcmcia on Amiga 1200 and Amiga 420 600.

Everyone using one of these boards should say 653 Y here. 654 655config DN_SERIAL 656 bool "Support for DN serial port (dummy)" 657 depends on APOLLO 658 659config SERIAL_CONSOLE 660 bool "Support for serial port console" 661 depends on (AMIGA || ATARI || MAC || SUN3 || SUN3X || VME || APOLLO) && (ATARI_MFPSER=y || ATARI_SCC=y || ATARI_MIDI=y || MAC_SCC=y || AMIGA_BUILTIN_SERIAL=y || GVPIOEXT=y || MULTIFACE_III_TTY=y || SERIAL=y || MVME147_SCC || SERIAL167 || MVME162_SCC || BVME6000_SCC || DN_SERIAL) 662 ---help--- 663 If you say Y here, it will be possible to use a serial port as the 664 system console (the system console is the device which receives all 665 kernel messages and warnings and which allows logins in single user 666 mode). This could be useful if some terminal or printer is connected 667 to that serial port. 668 669 Even if you say Y here, the currently visible virtual console 670 (/dev/tty0) will still be used as the system console by default, but 671 you can alter that using a kernel command line option such as 672 "console=ttyS1". (Try "man bootparam" or see the documentation of 673 your boot loader (lilo or loadlin) about how to pass options to the 674 kernel at boot time.) 675 676 If you don't have a VGA card installed and you say Y here, the 677 kernel will automatically use the first serial line, /dev/ttyS0, as 678 system console. 679 680 If unsure, say N. 681 682endmenu 683 684source "fs/Kconfig" 685 686source "kernel/Kconfig.instrumentation" 687 688source "arch/m68k/Kconfig.debug" 689 690source "security/Kconfig" 691 692source "crypto/Kconfig" 693 694source "lib/Kconfig" 695
