Examples for transitioning between operating systems are disclosed. An example apparatus includes reserved copy circuitry to copy state data of a first operating system from a first portion of first memory to a second portion of the first memory in response to an operating system toggle event; toggle event circuitry to, in response to a determination that the state data has been copied to the second portion of the first memory, initiate execution of a second operating system, the second operating system loaded from a hibernation file in second memory; and write out circuitry to copy the state data of the first operating system from the second portion of the first memory to the hibernation file while the second operating system is executed on the apparatus.

Technologies for operating system transitions in multiple-operating-system environments

An embodiment of a semiconductor package apparatus may include technology to identify a partial set of populated memory channels from a full set of populated memory channels of a multi-channel memory system, and complete a first boot of an operating system with only the identified partial set of memory channels of the multi-channel memory system. Other embodiments are disclosed and claimed.

First boot with one memory channel

Technologies for transitioning between operating systems include a computing device having a main memory and a data storage device. The computing device executes a first operating system and monitors for an operating system toggle event. The toggle event may be a software command, a hardware buttonpress, or other user command. In response to the toggle event, the computing device copies state data of the first operating system to a reserved memory area. After copying the state data, the computing device executes a second operating system. While the second operating system is executing, the computing device copies the state data of the first operating system from the reserved memory area to the data storage device. The computing device monitors for operating system toggle events during execution of the second operating system and may similarly toggle execution back to the first operating system. Other embodiments are described and claimed.

The present application is directed to access isolation for multi-operating system devices. In general, a device may be configured using firmware to accommodate more than one operating system (OS) operating concurrently on the device or to transition from one OS to another. An access isolation module (AIM) in the firmware may determine a device equipment configuration and may partition the equipment for use by multiple operating systems. The AIM may disable OS-based equipment sensing and may allocate at least a portion of the equipment to each OS using customized tables. When transitioning between operating systems, the AIM may help to ensure that information from one OS is not accessible to others. For example, the AIM may detect when a foreground OS is to be replaced by a background OS, and may protect (e.g., lockout or encrypt) the files of the foreground OS prior to the background OS becoming active.

Access isolation for multi-operating system devices

Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media (transitory and non-transitory) are described herein for accelerating a task that includes operation of a plurality of software modules among a plurality of parallel processing threads. In various embodiments, operation of the software modules may include postponement of operation of a first of the plurality of software modules in a first of the processing threads until a determination that the first software module is not deemed in operation. In various embodiments, the first software module may be deemed in operation while itself in operation or while awaiting completion of operation of any other software module called by the first software module.
