default ALPHA_GENERIC
- ---help---
+ help
This is the system type of your hardware. A "generic" kernel will
run on any supported Alpha system. However, if you configure a
kernel for your specific system, it will be faster and smaller.

Assume the presence of special features supported by QEMU PALcode
that reduce the overhead of system emulation.

There are two different types of booting firmware on Alphas: SRM,
which is command line driven, and ARC, which uses menus and arrow
keys. Details about the Linux/Alpha booting process are contained in

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.

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

config ALPHA_LARGE_VMALLOC
bool
- ---help---
+ 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.
int "Verbose Printing Mode (0=off, 1=on, 2=all)"
depends on VERBOSE_MCHECK
default 1
- ---help---

This option allows the default printing mode to be set, and then
possibly overridden by a boot command argument.

The frequency at which timer interrupts occur. A high frequency
minimizes latency, whereas a low frequency minimizes overhead of
process accounting. The later effect is especially significant

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
