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.
CONFORMING TO
This Linux-specific system call is available only on MIPS-based sys-
tems. It should not be used in programs intended to be portable.
BUGS
The current implementation ignores the addr and nbytes arguments.
Therefore, the whole cache is always flushed.
