This makes the kernel a bit faster as no tests + needs to be executed whether a floating-point instruction in the + kernel should be executed or not. + +config ADVANCED + bool "Advanced configuration options" + ---help--- + This gives you access to some advanced options for the CPU. The + defaults should be fine for most users, but these options may make + it possible for you to improve performance somewhat if you know what + you are doing. + + Note that the answer to this question won't directly affect the + kernel: saying N will just cause the configurator to skip all + the questions about these options. + + Most users should say N to this question. + +config RMW_INSNS + bool "Use read-modify-write instructions" + depends on ADVANCED + ---help--- + This allows to use certain instructions that work with indivisible + read-modify-write bus cycles. While this is faster than the + workaround of disabling interrupts, it can conflict with DMA + ( = direct memory access) on many Amiga systems, and it is also said + to destabilize other machines. It is very likely that this will + cause serious problems on any Amiga or Atari Medusa if set. The only + configuration where it should work are 68030-based Ataris, where it + apparently improves performance. But you've been warned! Unless you + really know what you are doing, say N.

Say N if not sure. + +config 060_WRITETHROUGH + bool "Use write-through caching for 68060 supervisor accesses" + depends on ADVANCED && M68060 + ---help--- + The 68060 generally uses copyback caching of recently accessed data. + Copyback caching means that memory writes will be held in an on-chip + cache and only written back to memory some time later. Saying Y + here will force supervisor (kernel) accesses to use writethrough + caching. Writethrough caching means that data is written to memory + straight away, so that cache and memory data always agree. + Writethrough caching is less efficient, but is needed for some + drivers on 68060 based systems where the 68060 bus snooping signal + is hardwired on. The 53c710 SCSI driver is known to suffer from + this problem. + +config ARCH_DISCONTIGMEM_ENABLE + def_bool !SINGLE_MEMORY_CHUNK + +config NODES_SHIFT + int + default "3" + depends on !SINGLE_MEMORY_CHUNK + +config ZORRO + bool "Amiga Zorro (AutoConfig) bus support" + depends on AMIGA + help + This enables support for the Zorro bus in the Amiga. If you have + expansion cards in your Amiga that conform to the Amiga + AutoConfig(tm) specification, say Y, otherwise N. Note that even + expansion cards that do not fit in the Zorro slots but fit in e.g. + the CPU slot may fall in this category, so you have to say Y to let + Linux use these. + +config AMIGA_PCMCIA + bool "Amiga 1200/600 PCMCIA support (EXPERIMENTAL)" + depends on AMIGA && EXPERIMENTAL + help + Include support in the kernel for pcmcia on Amiga 1200 and Amiga + 600.

The exact + behavior is platform-dependent, but normally the flash frequency is + a hyperbolic function of the 5-minute load average. + +# We have a dedicated heartbeat LED. :-) +config PROC_HARDWARE + bool "/proc/hardware support" + help + Say Y here to support the /proc/hardware file, which gives you + access to information about the machine you're running on, + including the model, CPU, MMU, clock speed, BogoMIPS rating, + and memory size. + +config ISA + bool + depends on Q40 || AMIGA_PCMCIA + default y + help + Find out whether you have ISA slots on your motherboard. ISA is the + name of a bus system, i.e. the way the CPU talks to the other stuff + inside your box. Other bus systems are PCI, EISA, MicroChannel + (MCA) or VESA. ISA is an older system, now being displaced by PCI; + newer boards don't support it.
