  61. bus while maintaining backward compatibility with cards made for

  79. actually two varieties of these cards: the older 16 bit PCMCIA cards
  80. and the newer 32 bit CardBus cards. If you want to use CardBus
  81. cards, you need to say Y here and also to "CardBus support" below.
  82. To use your PC-cards, you will need supporting software from David
  83. Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  84. for location). Please also read the PCMCIA-HOWTO, available from

  202. This option enables support for the Sun 3 series of workstations
  203. (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
  204. that all other hardware types must be disabled, as Sun 3 kernels
  205. are incompatible with all other m68k targets (including Sun 3x!).

  245. At some point in the future, this will cause floating-point math
  246. instructions to be emulated by the kernel on machines that lack a
  247. floating-point math coprocessor. Thrill-seekers and chronically
  248. sleep-deprived psychotic hacker types can say Y now, everyone else

  253. help
  254. The fpu uses normally a few bit more during calculations for
  255. correct rounding, the emulator can (often) do the same but this
  256. extra calculation can cost quite some time, so you can disable
  257. it here. The emulator will then "only" calculate with a 64 bit
  258. mantissa and round slightly incorrect, what is more than enough
  259. for normal usage.
  260. config M68KFPU_EMU_ONLY
  261. bool "Math emulation only kernel"
  262. depends on M68KFPU_EMU
  263. help
  264. This option prevents any floating-point instructions from being
  265. compiled into the kernel, thereby the kernel doesn't save any
  266. floating point context anymore during task switches, so this
  267. kernel will only be usable on machines without a floating-point
  268. math coprocessor. This makes the kernel a bit faster as no tests
  269. needs to be executed whether a floating-point instruction in the
  270. kernel should be executed or not.
  271. config ADVANCED

  273. ---help---
  274. This gives you access to some advanced options for the CPU. The
  275. defaults should be fine for most users, but these options may make
  276. it possible for you to improve performance somewhat if you know what
  277. you are doing.
  278. Note that the answer to this question won't directly affect the
  279. kernel: saying N will just cause the configurator to skip all
  280. the questions about these options.
  281. Most users should say N to this question.
  282. config RMW_INSNS
  283. bool "Use read-modify-write instructions"
  284. depends on ADVANCED
  285. ---help---
  286. This allows to use certain instructions that work with indivisible
  287. read-modify-write bus cycles. While this is faster than the
  288. workaround of disabling interrupts, it can conflict with DMA
  289. ( = direct memory access) on many Amiga systems, and it is also said
  290. to destabilize other machines. It is very likely that this will
  291. cause serious problems on any Amiga or Atari Medusa if set. The only
  292. configuration where it should work are 68030-based Ataris, where it
  293. apparently improves performance. But you've been warned! Unless you

  306. depends on ADVANCED && M68060
  307. ---help---
  308. The 68060 generally uses copyback caching of recently accessed data.
  309. Copyback caching means that memory writes will be held in an on-chip
  310. cache and only written back to memory some time later. Saying Y
  311. here will force supervisor (kernel) accesses to use writethrough
  312. caching. Writethrough caching means that data is written to memory
  313. straight away, so that cache and memory data always agree.
  314. Writethrough caching is less efficient, but is needed for some
  315. drivers on 68060 based systems where the 68060 bus snooping signal
  316. is hardwired on. The 53c710 SCSI driver is known to suffer from

  495. If you say Y here, it will be possible to use a serial port as the
  496. system console (the system console is the device which receives all
  497. kernel messages and warnings and which allows logins in single user
  498. mode). This could be useful if some terminal or printer is connected
  499. to that serial port.
  500. Even if you say Y here, the currently visible virtual console
  501. (/dev/tty0) will still be used as the system console by default, but
  502. you can alter that using a kernel command line option such as
  503. "console=ttyS1". (Try "man bootparam" or see the documentation of
  504. your boot loader (lilo or loadlin) about how to pass options to the
  505. kernel at boot time.)
  506. If you don't have a VGA card installed and you say Y here, the
  507. kernel will automatically use the first serial line, /dev/ttyS0, as
  508. system console.
  509. If unsure, say N.
