SPARC is a family of RISC microprocessors designed and marketed by

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

UltraSPARC. The UltraLinux project maintains both the SPARC32 and

SPARC64 ports; its web page is available at

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.

help
|

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.

will run faster if you say N here.

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.
