Abstract: Example implementations relate to booting a system comprising a system-on-a-chip (SOC) device. For example, boot code and system code comprising at least one selected from among an operating system and hypervisor code are stored in an on-chip non-volatile memory of a SoC device. By executing the boot code from the on-chip non-volatile memory, the system is booted from a mode in which power is removed from the system, where the booting includes loading the system code in the SoC device from the on-chip non-volatile memory without accessing storage off the SoC device.

Abstract: Examples disclosed herein relate to updating memory management information to boot an electronic device from a reduced power mode. In one implementation, prior to entering a reduced power mode, an electronic device creates a snapshot of instructions in a logically volatile partition of a partitioned persistent memory and manage the snapshot as a logically persistent partition. Prior to entering a resume mode, the electronic device updates memory management information to remap a portion of the partitioned memory resource including the snapshot to be managed as a logically volatile partition. The electronic device may resume execution from the snapshot.

Abstract: As part of starting a system including a system-on-a-chip (SoC) device from a mode in which power is removed from the system, the SoC device determines, based on the metadata, whether to resume the system to a prior system state. In response to the metadata indicating that the system is to be resumed to the prior system state, the system is resumed to the prior system state using system state information stored in the on-chip non-volatile memory.
