== NAME ==
'''cacheflush''' - flush contents of instruction and/or data cache

== SYNOPSIS ==
<code>
#include <asm/cachectl.h>

int cacheflush(char *addr, int nbytes, int cache);
</code>

== DESCRIPTION ==
cacheflush flushes contents of indicated cache(s) for 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 ==
; EINVAL : cache parameter is not one of ICACHE, DCACHE, or BCACHE.
; EFAULT : Some or all of the address range addr to (addr+nbytes-1) is not accessible.

== BUGS ==
The current implementation ignores the addr and nbytes parameters. Therefore always the whole cache is flushed.

== NOTE ==
This system call is only available on MIPS based systems. It should not be used in programs intended to be portable.
