Title: Realm management unit-private memory regions
Inventor: JASON PARKER
IPC: G06F12/14
Filed: 2017-06-28
Abstract: Software processes at a plurality of exception levels have portions corresponding to realms, where a memory region is associated with an owner realm and owner realms, e.g. guest virtual machines VMs, can prevent access to the associated regions to other realms or to processes at more privileged execution levels, e.g. the hypervisor. Realm management units, RMUs, manage realms. Depending on a status attribute said region associated to an owner realm can be RMU private memory for exclusive access by the RMU. The owner realm is also prevented access of the region if RMU-private memory. RMU-private memory is included in reclaimed regions of invalidated owner realms. Realm management data is stored in the private region, e.g. realm descriptors, execution context data, temporary intermediate data. Defining realm ownership for RMU-private regions avoids complex scrubbing of invalidated realms data, allows simpler identifications of regions to be invalidated, reduces memory footprint in export operations.
