Subject: [OCLUG-devel] Multi-processor hooks in kernel
Message-ID: <855DC88CEDE5904D91C2796721A310E8E879FA@wdscexbe04.sc.wdc.com>

I'm new to your group, but I'm not new to Linux (20 years).  I used to work
for Silicon Graphics, Inc., and I know that a lot of SGI features have been
added to Linux.

What I'm looking for is any information on multi-processing hooks in the
kernel; via syscalls or whatever.  In SGI IRIX, there were system calls that
could lock a processor to an application, synchronize processors on a single
task (usually a loop), identify one processor to handle all interrupts, etc.

Does anyone know if these features exist in Linux, and if they do, is there
documentation on their use?

Thanks in advance.
