8. Target Hash

Each BSP must provide an implementation of the rtems_get_target_hash() directive. The default implementation is based on the CPU counter frequency. A BSP-specific implementation may be provided which covers also for example the device tree, settings of the memory controller, processor and bus frequencies, a serial number of a chip, etc. For a BSP-specific implementation start with the default implementation and add more values to the target hash using the functions _Hash_Add_data() and _Hash_Add_string(). The target hash can be used to distinguish test suite results obtained from different target systems.
