An apparatus and method are provided which take advantage of heterogeneous compute capability to dynamically pick the best operating core for BIOS power-up flows and sleep exit flows (e.g., S3, S4, and/or S5). The selection of the BSP is moved to an early power-up time instead of a fixed hardware selection at any time. For maximum boot performance, the system selects the fastest capable core as the BSP at an early power-up time. In addition, for maximum power saving, the system selects the most power efficient core as the BSP. Processor or switching for selecting the BSP happens during the boot-up as well as power-up flows (e.g., S3, S4, and/or S5 flows).

Apparatus and method for dynamic selection of an optimal processor core for power-up and/or sleep modes

Systems, apparatuses and methods may provide for technology that assumes, by a root of trust located in a trusted region of a system on chip (SOC), control over a reset of the SOC and conducting, by the root of trust, an authentication of an update package in response to an update condition. The root of trust technology may also apply the update package to firmware located in non-volatile memory (NVM) associated with a microcontroller of the SOC if the authentication is successful.

SOC-assisted resilient boot

Methods, apparatus, systems and articles of manufacture are disclosed to utilize non-volatile memory for computer system boot. An example processor platform includes a non-volatile memory coupled to a processing unit via a bus, and a microcontroller to: configure the processing unit to store, on the non-volatile memory, a heap and a stack for execution of boot code, and configure the processing unit to execute the boot code stored on the non-volatile memory.

Methods and apparatus to utilize non-volatile memory for computer system boot

Systems, apparatuses and methods may provide for technology that conducts a first copy of firmware data from a first partition in a storage device to a second partition in the storage device, detects a recovery condition with respect to the firmware data in the first partition, and automatically conducts a second copy of the firmware data from the second partition to the first partition in response to the recovery condition. In one example, the firmware data defines one or more settings for firmware code.

Technology to enable secure and resilient recovery of firmware data

Methods, apparatus, systems and articles of manufacture for mitigating a firmware failure are disclosed. An example apparatus includes at least one hardware processor and first memory including instructions to be executed by the at least one hardware processor. The example apparatus further includes mask memory including a feature mask associated with a first firmware version, the feature mask identifying features of the first firmware version to be disabled. A platform firmware controller is to apply the first firmware version to the first memory for execution by the at least one processor, initialize the at least one processor using the feature mask, and in response to a detection of a failure, determine a first de-feature mask based on a second de-feature mask previously used by the at least one processor and the feature update mask; and initialize the processor using the first de-feature mask.

Methods and apparatus for in-field mitigation of firmware failures

A computerized component, designed to be used in a vehicle, is able to detect an ambient environmental variable; determine a memory profile corresponding to the ambient environmental variable; access memory parameters from the memory profile; and configure memory of the computerized component based on the accessed memory parameters. Another computerized component may be used to detect that the computerized component is initiating a shutdown procedure; obtain an ambient environmental variable, the ambient environmental variable indicating a state of an operating environment of the computerized component; identify memory parameters of random access memory integrated with the computerized component; and write the memory parameters to a memory profile stored in non-volatile storage in the computerized component, the memory profile keyed to the ambient environmental variable.

Soc-assisted resilient boot

An electronic device may be provided that includes a first controller, a second controller, and a bus to connect between the first controller and the second controller. The electronic device may also include a first signal line between the first controller and the second controller, and the first controller to provide a first signal on the first signal line to the second controller to wake up the second controller from a low power mode.

Electronic device having a controller to enter a low power mode

Systems, apparatuses and methods may provide for technology that based on information from a connected display device, forms a determination whether to connect a discrete graphics processor or an integrated graphics processor to the connected display device, the information corresponding to whether the connected display device is to be driven by the integrated graphics processor or the discrete graphics processor.

Switchable hybrid graphics

Techniques for adaptive interface support are described. In one embodiment, for example, an apparatus may comprise logic, at least a portion of which is in hardware, the logic to execute a basic input/output system (BIOS), determine a respective impedance state for each of one or more pins in an M.2 physical interface, determine an interface type for a peripheral device coupled with the M.2 physical interface based on the impedance states for the one or more pins, and control an operational state of the peripheral device during execution of the BIOS, based on the interface type for the peripheral device. Other embodiments are described and claimed.
