  56. bus while maintaining backward compatibility with cards made for

  76. cards, you need to say Y here and also to "CardBus support" below.
  77. To use your PC-cards, you will need supporting software from David
  78. Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>

  200. This option enables support for the Sun 3 series of workstations
  201. (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
  202. that all other hardware types must be disabled, as Sun 3 kernels

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

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

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

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

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