In-place recovery of fatal system errors at virtualization hosts. A device identifies an occurrence of a fatal system error in the first instance of a host operating system (OS) executing in a computer system. The device determines to perform an in-place recovery for the fatal system error. The device performs the in-place recovery, including pausing the execution of a virtual machine (VM) by the first instance of the host OS, preserving a state of the VM within system memory of the computer system, and resuming the execution of the VM by a second instance of the host OS executing in the computer system based on the state of the VM that is preserved within the system memory of the computer system.

A computing device has an energy storage device system with multiple energy storage devices. Various different criteria are used to determine which one or more of the multiple energy storage devices to charge or discharge at any given time to provide power to the computing device. The criteria can include characteristics of the energy storage devices as well as hardware and/or physical characteristics of the computing device, characteristics of the energy storage devices and/or the computing device that change while the computing device operates, and predicted behavior or usage of the computing device. These criteria are evaluated during operation of the computing device, and the appropriate energy storage device(s) from which to draw power or to charge at any given time based on these criteria are determined.

Dynamic power source selection, charging, and discharging

Techniques described herein enable the implementation of a secure driver framework. In one example, a method includes managing an unsecure operating system execution environment comprising a first user mode and a first kernel mode. The method can also include managing a secure execution environment comprising a second user mode and a second kernel mode, and executing a secure driver within the second user mode of the secure execution environment in response to a system call from an unsecure driver in the first kernel mode or the first user mode, wherein the secure driver enables the unsecure driver to communicate with a secure device. Furthermore, the method can include providing one or more system services of the second kernel mode to the secure driver.
