Abstract
Methods, systems, and devices for access control configurations for inter-processor communications are described to support reconfiguration of a dynamic access control configuration at a device. The configuration may support additional configuration fields that may be added to existing access control rules of the device. A processor of the device may request creation of a new shared memory resource, using a subregion of an existing memory resource, where the additional fields may indicate a parent memory resource for the new memory resource. The additional fields may also include a value which may indicate a processor which has write permission for a respective memory region of the shared memory, where other processors of the device may be prevented from writing to the memory region. The additional fields may further indicate a chain of delegation, or a history, of which processors have been assigned the exclusive write permission for the respective memory region.
