NAME

arm_drain_writebuf — drains the CPU write buffer

SYNOPSIS

ARM Architecture Library (libarm, -larm)
#include <machine/sysarch.h>

int
arm_drain_writebuf(void);

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.

arm_drain_writebuf() will never fail so will always return 0.
