Sun Microsystems, incorporated. This port covers the newer 64-bit

UltraSPARC. The UltraLinux project maintains both the SPARC32 and

This lets you select the page size of the kernel.

8KB and 64KB work quite well, since Sparc ELF sections
|

provide for up to 64KB alignment.
|

Therefore, 512KB and 4MB are for expert hackers only.

If you don't know what to do, choose 8KB.

This kernel feature is useful for number crunching applications
|
|
that may need to compute untrusted bytecode during their
|
|
execution. By using pipes or other transports made available to
|
|
the process as file descriptors supporting the read/write
|
|
syscalls, it's possible to isolate those applications in
|
|
their own address space using seccomp. Once seccomp is
|
|
enabled via /proc/<pid>/seccomp, it cannot be disabled
|
|
and the task is only allowed to execute a few safe syscalls
|
|
defined by each seccomp mode.

one CPU, say Y.
|

singleprocessor machines. On a singleprocessor machine, the kernel

will run faster if you say N here.

This option reduces the latency of the kernel when reacting to
|
|
real-time or interactive events by allowing a low priority process to
|
|
be preempted even if it is in kernel mode executing a system call.
|
|
This allows applications to run more reliably even when the system is
|
|
under load.
|

Say Y here if you are building a kernel for a desktop, embedded
|
|
or real-time system. Say N if you are unsure.

The Extended Industry Standard Architecture (EISA) bus was

The EISA bus provided some of the features of the IBM MicroChannel
|

bus while maintaining backward compatibility with cards made for
|
|
the older ISA bus. The EISA bus saw limited use between 1988 and
|
|
1995 when it was made obsolete by the PCI bus.
