    摘要： Systems and methods provide multi-modal based updates to firmware utilized by a hardware component of an IHS (Information Handling System), where the firmware updates are managed by a remote access controller of the IHS that provides remote management of the hardware component. The remote access controller receives a notification of an update to an agreement for utilization of the hardware component, where the agreement indicates firmware modes authorized for use by the hardware component. Firmware modes are identified that are locally stored by the hardware component. Any firmware modes are identified that are authorized for use by the hardware component based on the updated first agreement and that are not locally stored by the hardware component, and the identified firmware modes are retrieved for local storage by the hardware component. In this manner, firmware utilized in an IHS remains consistent with applicable service agreements.

    摘要： A system for providing usage model context aware power management in secure systems with embedded hardware security modules is disclosed. The system determines a context associated with a transaction with a memory device that is initiated by a host device. Based on the context, the system sets conditions within its internal data structures and state machines. The context may indicate that the transaction is a secure transaction requiring cryptographic services of the memory device. Flags are set in firmware of the memory device indicating a need for context aware power management and for cryptographic services. If a power management function to reduce power to the memory device is to be executed, the firmware rejects the transaction until the memory device reenters a functional mode. If the function is not to be executed, the firmware provides the host with a notification of an impending power state change for the memory device.

    摘要： A peripheral device package for use in a host computing device has a plurality of compute elements and a plurality of resources shared by the plurality of compute elements. A datastructure is stored in a hidden memory of the peripheral device package. The data structure holds metadata about ownership of resources of the peripheral device package by a plurality of user runtime processes of the host computing device which use the compute elements. At least one of the user runtime processes is a secure user runtime process. The peripheral device package has a command processor configured to use the datastructure to enforce isolation of the resources used by the secure user runtime process.
