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. For example, additional configuration fields may be added to existing access control rules of the device, where these additional fields may be configured by a processor sending information to a receiving processor, via a shared memory resource or region of the device. The additional fields may include a read-only value which may specify a processor which has exclusive write permission for a memory region of the share memory. This value may indicate the sending processor of the memory region, and the value may be set by access control hardware when the additional field is changed. Other processors of the device may be prevented from writing to the memory region.
