In one embodiment, a multiprocessor computer system comprises at least a first partition having a first operating system and a second partition having a second operating system, comprising logic in the first operating system to generate a request to remove a device from the first partition, logic in a firmware module in the computer system to invoke an ACPI interface eject method for the device in response to the request to remove the device, determine whether the device has memory spaced allocated to it by firmware in the computer system, and reject the ACPI interface eject method when the device has memory spaced allocated to it by firmware in the computer system.

Resource ejectability in multiprocessor systems

Systems and methods for testing non-volatile storage devices are disclosed that provide functionality to control when testing of the non-volatile storage device is performed. In one embodiment, information stored in persistent memory indicates whether testing is enabled or disabled. For example, the testing information may indicate that testing is to be performed upon a first initialization of a non-volatile storage device, but not in connection with subsequent power-up events. Furthermore, functionality is disclosed for re-running and/or bypassing testing of the non-volatile storage device.

Automatic and on-demand testing of non-volatile storage devices

An electronic device is disclosed comprising a non-volatile memory storing a first version of a control program (CP), a first header comprising a first version identifier (VID) identifying the first version of the CP and a first VID check code generated in response to at least the first VID. The non-volatile memory further stores a second version of the CP, and a second header comprising a second VID identifying the second version of the CP and a second VID check code generated in response to at least the second VID. When the first and second VIDs are valid, the electronic device selects between the first version and the second version of the CP in response to the first and second VIDs, and executes the selected version of the CP.

Updating firmware of an electronic device by storing a version identifier in a separate header

A method of allocating a resource in a computer system having a plurality of operating systems, and related system, are disclosed. In at least one embodiment, the method includes providing an advanced configuration and power interface (ACPI) operating to facilitate interactions between at least one of the plurality of the operating systems and one or more of the resource, a hardware device, and firmware, and determining whether the resource is allocated to a first of the plurality of operating systems. The method further includes ejecting the resource from the first operating system, and allocating the resource to a second of the plurality of operating systems.

Method and system for dynamically reallocating a resource among operating systems without rebooting of the computer system

In one embodiment, a multiprocessor computer system comprises at least a first partition having a first operating system comprising logic to initiate a request to add a first cell to the first partition, open a communication interface between the first operating system and a firmware module on the first cell, and transmit from the first partition to the first cell a compatibility command, logic in the first cell to determine whether the first cell is compatible with the first partition, and logic in the first partition to add the first cell to the first partition in response to a determination that the first cell is compatible with the first partition.
