Modular I/O configurations for edge computing using disaggregated chiplets

A method performed by an edge computing device, the edge computing device comprising at least one hardware resource composed from a configuration of a plurality of chiplets, wherein the chiplets provide disaggregated portions of the hardware resource, including a plurality of disaggregated input/output (I/O) modules, and the chiplets comprise a dedicated chiplet that includes I/O controller logic, and the method comprising:

• identifying a condition for use of the hardware resource, based on an edge computing workload received at the edge computing device;
• identifying the hardware resource as available in the edge computing device to be used for the edge computing workload according to the configuration;
• obtain properties of a configuration for the hardware resource that is available to be implemented with the chiplets, the configuration enabling the hardware resource to satisfy the condition for use of the hardware resource;
• composing the chiplets into the configuration, according to the properties of the configuration, to enable the use of the hardware resource for the edge computing workload,
• wherein deployment of the chiplets implement a topology to the disaggregated I/O modules according to the properties of the configuration, wherein the I/O controller logic controls I/O connections of the disaggregated I/O modules to provide communications between the disaggregated portions of the hardware resource and achieve hardware modularity for the hardware resource;
• verifying the configuration of the chiplets in the hardware resource, wherein the chiplets provide attestation for the use of the hardware resource with the edge computing workload according to the configuration, wherein each chiplet contains logic to provide cryptographic device identity, attestation, and data encryption, the logic producing an attestation key;
• using the attestation key to identify a plurality of chiplet configurations and provide the attestation to a verifier that contains a policy describing at least one of acceptable or unacceptable configurations;
• and
• determine and save the properties of the configuration for the hardware resource that are available to be implemented with the chiplets in order to reuse the configuration with a subsequent edge computing workload.
