Abstract: Techniques are disclosed relating to an I/O agent circuit. The I/O agent circuit may include a memory bank and be coupled to a set of devices. The I/O agent circuit may assign a device of the set of devices to a subdomain of a plurality of subdomains implemented for the memory bank. The I/O agent circuit may store, in that memory bank, a set of transactions of the device in association with the subdomain assigned to the device. The I/O agent circuit may execute the set of transactions such that transactions stored in the memory bank in association with other ones of the plurality of subdomains than the subdomain assigned to the device do not block execution of the set of transactions.
