HP-UX is a big, expensive, proprietary UNIX which runs on its own special architecture, PA-RISC, or the still-unusual Itanium. So it's not exactly the sort of UNIX you can install over a weekend if you feel like tinkering with it. (Though not completely impossible for a home user to get -- older hardware can sometimes be had for a bargain on ebay.)

cacheflush
CACHEFLUSH(2) Linux Programmer's Manual CACHEFLUSH(2)
NAME
cacheflush - flush contents of instruction and/or data cache
SYNOPSIS
#include <asm/cachectl.h>
int cacheflush(char *addr, int nbytes, int cache);
DESCRIPTION
cacheflush() flushes the contents of the indicated cache(s) for the user addresses in the range addr to (addr+nbytes-1). cache may be one
of:
ICACHE Flush the instruction cache.
DCACHE Write back to memory and invalidate the affected valid cache lines.
BCACHE Same as (ICACHE|DCACHE).
RETURN VALUE
cacheflush() returns 0 on success or -1 on error. If errors are detected, errno will indicate the error.
ERRORS
EFAULT Some or all of the address range addr to (addr+nbytes-1) is not accessible.
EINVAL cache is not one of ICACHE, DCACHE, or BCACHE (but see BUGS).
CONFORMING TO
Historically, this system call was available on all MIPS UNIX variants including RISC/os, IRIX, Ultrix, NetBSD, OpenBSD, and FreeBSD (and
also on some non-UNIX MIPS operating systems), so that the existence of this call in MIPS operating systems is a de-facto standard.
Caveat
cacheflush() should not be used in programs intended to be portable. On Linux, this call first appeared on the MIPS architecture, but
nowadays, Linux provides a cacheflush() system call on some other architectures, but with different arguments.
BUGS
Linux kernels older than version 2.6.11 ignore the addr and nbytes arguments, making this function fairly expensive. Therefore, the whole
cache is always flushed.
This function always behaves as if BCACHE has been passed for the cache argument and does not do any error checking on the cache argument.
