Function Documentation

L4_CV int l4rm_init	(	int	have_l4env,
		l4rm_vm_range_t	used[],
		int	num_used
	)

Init Region Mapper.

Parameters:

	have_l4env	Set to != 0 if started with the L4 environment (L4RM then uses the default dataspace manager to allocate its descriptor heap)
	used	Used VM address range, do not use for internal data. These address ranges are only excluded during l4rm_init, if an address range should further not be used, it also has to be reserved (l4rm_area_reserve()) after L4RM is initialized.
	num_used	Number of elements in used.

Returns:

0 on success, -1 if initialization failed

L4_CV l4_threadid_t l4rm_region_mapper_id

(

void

)

Return service id of region mapper thread.

Returns:

Id of region mapper thread.

L4_CV void l4rm_service_loop

(

void

)

Region mapper service loop.

Used in l4env_startup (l4env).
