NAME
arm_drain_writebuf —
drains the CPU write buffer
SYNOPSIS
#include
<machine/sysarch.h>
int
arm_drain_writebuf();
DESCRIPTION
arm_drain_writebuf()
will make sure that all the entries in the processor write buffer are
written out to memory.
Not all processors support this operation (currently only the SA110 does). Those processes that do not, treat this function as a null-op.
ERRORS
arm_drain_writebuf() will never fail so
will always return 0.
