  • Publication number: 20180173294
    Abstract: Technologies for secure hybrid standby power management include a computing device with a processor supporting low-power idle standby. An operating system writes a power management sleep request, such as an ACPI S3 request, to a power management control register of the computing device. The processor traps the write to the power management control register and executes a firmware sleep mapper that causes the processor to enter an idle standby power state such as S0ix. The firmware sleep mapper may be included in a firmware isolated memory region. The address of the firmware sleep mapper may be included in a model-specific register of the processor. The processor may verify the firmware sleep mapper before execution. In response to a wake event, the processor resumes the firmware sleep mapper, which switches the processor to real mode and jumps to a waking vector of the operating system. Other embodiments are described and claimed.

  • Publication number: 20170286086
    Abstract: A mechanism is described for facilitating dynamic capsule generation and recovery in computing environments according to one embodiment. A method of embodiments, as described herein, includes accessing a current firmware and a capsule driver binary file (“capsule file”) from a storage device, and merging the current firmware with the capsule file and a capsule header into a capsule payload. The method may further include assigning a security protocol to the capsule payload to ensure a secured capsule payload, and storing the secured capsule payload at the storage device for subsequent updates.

  • Publication number: 20170277530
    Abstract: Technologies for performing a secure firmware update include a compute device that includes a memory device to store firmware update payload, one or more devices that have direct memory access (DMA) to the memory, a DMA remap module, and a firmware update module. The DMA remap module is to create a memory isolation domain for each of the one or more devices. Each memory isolation domain comprises a physical address space in the memory that is mutually exclusive to the physical address spaces of the other memory isolation domains. The firmware update module is to (i) analyze the firmware update payload to identify one or more of the devices associated with the firmware update payload and (ii) move the firmware update payload to the memory isolation domains of each associated device to enable secure transmission of the firmware update payload to the associated devices.

  • Publication number: 20170075682
    Abstract: Apparatuses, methods and storage medium associated with provision of power management data packages are disclosed herein. In embodiments, an apparatus may include one or more processors, memory to store a power management data package having a first plurality of descriptions of always present fixed platform devices and a second plurality of descriptions of potentially present variable platform devices; and firmware coupled with the one or more processors and memory to provide basic input/output services to an operating system operated by the one or more processors, wherein the operating system has an operational requirement for the power management data package. The basic input/output services may include a service to modify the power management data package to bring the power management data package into compliance with the operational requirement of the operating system. Other embodiments may be described and/or claimed.
