This patch integrates three region maps into each PD session to reduce the session overhead and to simplify the PD creation procedure. Please refer to the issue cited below for an elaborative discussion. Note the API change: With this patch, the semantics of core's RM service have changed. Now, the service is merely a tool for creating and destroying managed dataspaces, which are rarely needed. Regular components no longer need a RM session. For this reason, the corresponding argument for the 'Process' and 'Child' constructors has been removed. The former interface of the 'Rm_session' is not named 'Region_map'. As a minor refinement, the 'Fault_type' enum values are now part of the 'Region_map::State' struct. Issue #1938 |

The bomb test starts as many components as configured and as RAM
resources admit. This utilitiy acts as a fork bomb to stress test core, init,
and of course the kernel.
The master component (bomb-master) starts a given number of children and it
donates the available memory in equal shares to the children. The children
again start new children until all their memory resources are depleted or a
given generation count of children is reached (depth of the fork tree).
The bomb-master begins to kill all children after a given period of time and
restarts the creation of children afterwards.
Configuration
-------------
! ...
! <config rounds="1" generations="1" children="2" sleep="2000" demand="1048576"/>
! ...
rounds: solely used by master bomb - number of start/kill rounds
generations: maximum generations of children, i.e. tree depth, to create
children: number of children per bomb parent to create
sleep: time in ms to wait between creation and killing of children by
bomb-master
demand: amount of RAM in bytes which are required to spawn a new child
The xml attributes are all optional. If the XML attributes are not set,
the values given in the example config are used as default by the bomb-master.
