C++ (Cpp) mtrr_commit Examples

Example #1

File: sys_machdep.c Project: avsm/openbsd-xen-sys

int
amd64_set_mtrr(struct proc *p, void *args, register_t *retval)
{
	int error, n;
	struct amd64_set_mtrr_args ua;

	if (mtrr_funcs == NULL)
		return ENOSYS;

	error = suser(p, 0);
	if (error != 0)
		return error;

	error = copyin(args, &ua, sizeof ua);
	if (error != 0)
		return error;

	error = copyin(ua.n, &n, sizeof n);
	if (error != 0)
		return error;

	error = mtrr_set(ua.mtrrp, &n, p, MTRR_GETSET_USER);
	if (n != 0)
		mtrr_commit();

	copyout(&n, ua.n, sizeof n);

	return error;
}

Example #2

	if (ret && ret != -ENOSYS)
		return ret;
#endif
	/* Initialise the CPU cache(s) */
	return init_cache();
