519 There are two different types of booting firmware on Alphas: SRM,
520 which is command line driven, and ARC, which uses menus and arrow
521 keys. Details about the Linux/Alpha booting process are contained in
522 the Linux/Alpha FAQ, accessible on the WWW from
523 <http://www.alphalinux.org/>.
525 The usual way to load Linux on an Alpha machine is to use MILO
526 (a bootloader that lets you pass command line parameters to the
527 kernel just like lilo does for the x86 architecture) which can be
528 loaded either from ARC or can be installed directly as a permanent
529 firmware replacement from floppy (which requires changing a certain
530 jumper on the motherboard). If you want to do either of these, say N
531 here. If MILO doesn't work on your system (true for Jensen
532 motherboards), you can bypass it altogether and boot Linux directly
533 from an SRM console; say Y here in order to do that. Note that you
534 won't be able to boot from an IDE disk using SRM.

550 This enables support for systems with more than one CPU. If you have
551 a system with only one CPU, say N. If you have a system with more
554 If you say N here, the kernel will run on uni- and multiprocessor
555 machines, but will use only one CPU of a multiprocessor machine. If
556 you say Y here, the kernel will run on many, but not all,
557 uniprocessor machines. On a uniprocessor machine, the kernel
558 will run faster if you say N here.
560 See also the SMP-HOWTO available at

586 See <file:Documentation/vm/numa> for more.
591 bool "NUMA Support (EXPERIMENTAL)"
592 depends on DISCONTIGMEM && BROKEN
594 Say Y to compile the kernel to support NUMA (Non-Uniform Memory

596 server machines. If in doubt, say N.

605 The Wait for Interrupt (WTINT) PALcall attempts to place the CPU
606 to sleep until the next interrupt. This may reduce the power
607 consumed, and the heat produced by the computer. However, it has
608 the side effect of making the cycle counter unreliable as a timing
609 device across the sleep.
611 For emulation under QEMU, definitely say Y here, as we have other
612 mechanisms for measuring time than the cycle counter.
614 For EV4 (but not LCA), EV5 and EV56 systems, or for systems running
615 MILO, sleep mode is not supported so you might as well say N here.
617 For SMP systems we cannot use the cycle counter for timing anyway,

631 Process creation and other aspects of virtual memory management can

633 allocations. This equates to about 8GB.
635 Under normal circumstances, this is so far and above what is needed
636 as to be laughable. However, there are certain applications (such
637 as benchmark-grade in-kernel web serving) that can make use of as
638 much vmalloc space as is available.

647 depends on VERBOSE_MCHECK
650 This option allows the default printing mode to be set, and then
651 possibly overridden by a boot command argument.
653 For example, if one wanted the option of printing verbose
654 machine checks, but wanted the default to be as if verbose
655 machine check printing was turned off, then one would choose
656 the printing mode to be 0. Then, upon reboot, one could add
657 the boot command line "verbose_mcheck=1" to get the normal
658 verbose machine check printing, or "verbose_mcheck=2" to get
659 the maximum information available.
661 Take the default (1) unless you want more control or more info.

669 The frequency at which timer interrupts occur. A high frequency
670 minimizes latency, whereas a low frequency minimizes overhead of
671 process accounting. The later effect is especially significant
672 when being run under QEMU.
674 Note that some Alpha hardware cannot change the interrupt frequency
675 of the timer. If unsure, say 1024 (or 1200 for Rawhide).
