[[PageOutline]]

The [source:soft/giet_vm/giet_common/utils.c utils.c] and [source:soft/giet_vm/giet_common/utils.h util.h] files define the functions used to extract informations from the mapping_info data structure (defined in the ''mapping_info.h'' file), that has been loaded into system memory by the boot-loader.

They are prefixed by "_" to remind that they can only be executed by a processor in kernel mode.
