Abstract: Three components are used to adjust the CPU peak power based on the USB TYPE-C device states. These components include operating system (OS) Peak Power Manager, USB TYPE-C Connector Manager, and USB TYPE-C Protocol Device Driver. The USB TYPE-C Connector Manager sends a synchronous request to the OS Peak Power Manager when a USB TYPE-C power sink device is attached or detached, and the USB TYPE-C Protocol Device Driver sends a synchronous request to the Peak Power Manager when the power sink transitions device state. The Peak Power Manager takes power budget from the CPU when the USB TYPE-C connector is attached to a power sink and is active (e.g., high power device state), and gives back the power budget to the CPU for performance when the USB TYPE-C connector is either detached or the attached and power sink device is idle (lowest device state).

Abstract: Systems and methods provide isolated workspaces operating on an IHS (Information Handling System) with use of pre-boot resources of the IHS that are not directly accessible by the workspaces. Upon notification of a workspace initialization, a segregated variable space, such as a segregated memory utilized by a UEFI (Unified Extensible Firmware Interface) of the IHS, is specified for use by the workspace. The segregated variable space is initialized and populated with pre-boot variables, such as UEFI variables, that are allowed for configuration by the workspace. Upon a workspace issuing a request to configure a pre-boot variable, the segregated variable space is identified that was mapped for use by the workspace. The requested pre-boot variable configuration is allowed based on whether the pre-boot variable is populated in the segregated variable space. When the requested pre-boot variable configuration is allowed, the pre-boot variable is configured on behalf of the workspace.
