    Abstract: Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to implement software defined silicon feature licensing are disclosed. Example licensor systems disclosed herein includes a third party verifier to verify one or more credentials included in a request to become an authorized delegated licensor, the request received from a third party. Disclosed example licensor systems also include a feature identifier to identify a feature of a silicon structure which the third party is to be granted the authority to license. Disclosed example licensor systems further include a configuration installation code generator to generate feature configuration installation code, the feature configuration installation code to be used by the third party to generate at least a portion of the license, the portion of the license to be used by a licensee to configure the silicon structure to access the licensed feature, and contents of the feature configuration installation code encrypted to prevent access by the authorized delegated licensor.

    Abstract: Methods and apparatus for restricted deployment of targeted processor firmware updates. During a patch enabling per-work flow, service entitlement license information comprising one of more service entitlements is generated and provisioned on one or more computing platforms. A restricted deployment microcode (uCode) update release (aka uCode patch) targeted for platforms having CPUs and/or XPUs with certain part identifier is sent to the one or more platforms. Run-time software and/or firmware on the platforms are executed to access the provisioned service entitlement license information, which is used to authentic and verify the restricted deployment uCode update release using a service entitlement having a part identifier associated with the platform's CPU. In one solution, authentication is performed using a hash-matching scheme and verification is used to verify the platform is properly licensed to load uCode included in the restricted deployment microcode (uCode) update release into the CPU.
