There are two different types of booting firmware on Alphas: SRM,
which is command line driven, and [31mCONFIG_ARC[0m, which uses menus and arrow
keys. Details about the Linux/Alpha booting process are contained in
the Linux/Alpha FAQ, accessible on the WWW from
<http://www.alphalinux.org/>.
The usual way to load Linux on an Alpha machine is to use MILO
(a bootloader that lets you pass command line parameters to the
kernel just like lilo does for the x86 architecture) which can be
loaded either from [31mCONFIG_ARC[0m or can be installed directly as a permanent
firmware replacement from floppy (which requires changing a certain
jumper on the motherboard). If you want to do either of these, say N
here. If MILO doesn't work on your system (true for Jensen
motherboards), you can bypass it altogether and boot Linux directly
from an SRM console; say Y here in order to do that. Note that you
won't be able to boot from an [31mCONFIG_IDE[0m disk using SRM.
If unsure, say N.

---help---
This enables support for systems with more than one CPU. If you have
a system with only one CPU, say N. If you have a system with more
than one CPU, say Y.
If you say N here, the kernel will run on uni- and multiprocessor
machines, but will use only one CPU of a multiprocessor machine. If
you say Y here, the kernel will run on many, but not all,
uniprocessor machines. On a uniprocessor machine, the kernel
will run faster if you say N here.
See also the [31mCONFIG_SMP[0m-HOWTO available at
<http://www.tldp.org/docs.html#howto>.
If you don't know what to do here, say N.

Say Y to support efficient handling of discontiguous physical memory,
for architectures which are either [31mCONFIG_NUMA[0m (Non-Uniform Memory Access)
or have huge holes in the physical address space for other reasons.

---help---
The Wait for Interrupt (WTINT) PALcall attempts to place the CPU
to sleep until the next interrupt. This may reduce the power
consumed, and the heat produced by the computer. However, it has
the side effect of making the cycle counter unreliable as a timing
device across the sleep.
For emulation under QEMU, definitely say Y here, as we have other
mechanisms for measuring time than the cycle counter.
For EV4 (but not LCA), EV5 and EV56 systems, or for systems running
MILO, sleep mode is not supported so you might as well say N here.
For [31mCONFIG_SMP[0m systems we cannot use the cycle counter for timing anyway,
so you might as well say Y here.
If unsure, say N.

bool
---help---
Process creation and other aspects of virtual memory management can
be streamlined if we restrict the kernel to one PGD for all vmalloc
allocations. This equates to about 8GB.
Under normal circumstances, this is so far and above what is needed
as to be laughable. However, there are certain applications (such
as benchmark-grade in-kernel web serving) that can make use of as
much vmalloc space as is available.
Say N unless you know you need gobs and gobs of vmalloc space.

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

The frequency at which timer interrupts occur. [31mCONFIG_A[0m high frequency
minimizes latency, whereas a low frequency minimizes overhead of

when being run under QEMU.

of the timer. If unsure, say 1024 (or 1200 for Rawhide).

tristate "SRM environment through procfs"
depends on [31mCONFIG_PROC_FS[0m
---help---
If you enable this option, a subdirectory inside /proc called
/proc/srm_environment will give you access to the all important
SRM environment variables (those which have a name) and also
to all others (by their internal number).
SRM is something like a BIOS for Alpha machines. There are some
other such BIOSes, like AlphaBIOS, which this driver cannot
support (hey, that's not SRM!).
Despite the fact that this driver doesn't work on all Alphas (but
only on those which have SRM as their firmware), it's save to
build it even if your particular machine doesn't know about SRM
(or if you intend to compile a generic kernel). It will simply
not create those subdirectory in /proc (and give you some warning,
of course).
This driver is also available as a module and will be called
srm_env then.
