Embodiments of the present disclosure provide a system and method to cache Desktop Bus (D-Bus) objects. According to one embodiment, an Information Handling System (IHS) includes a Remote Access Controller (RAC) with computer-executable instructions that cause the RAC to receive a request for a data object from a requester, and determine whether the data object is to be obtained from a cache or directly from the Desktop Bus (D-Bus) service. The instructions further cause the RAC to obtain the requested data object from either the D-Bus service or the cache based upon the determination, and send the obtained data object to the requester in response to the request. The data object is generated by a D-Bus service that communicates through the D-Bus.

Methods and systems for power management are disclosed. The disclosed power management method and systems may improve the likelihood of data processing systems providing desired computer implemented services while meeting power budget goals and/or other types of goals regarding power consumption, use, and/or provisioning. To improve the likelihood of the power budgets being met, the system may dynamically update power allocations to various components of data processing systems. The power allocations may be dynamically allocated by predicting how changes in existing power allocations may impact the ability of the data processing system to service power allocation requests. If it appears that changes in one or more existing power allocations may allow a power allocation request to be serviced, then the power allocations may be dynamically reallocated to free allocable power. The freed allocable power may be used to service the power allocation.
