A method and apparatus for cooperative guest firmware are described. In one embodiment, the method includes the launch of a virtual machine (VM) including a guest operating system (OS) and guest firmware. Prior to launching the VM, a data structure is generated in memory and is associated with the guest firmware to provide a virtualization policy provided by the VM as well as processor and platform configuration information to the guest firmware. In one embodiment, the guest firmware uses the data structure to access static information regarding the virtualization policy, as well as the processor and platform configuration information in response to requests from the guest OS. However, when the guest OS requires a host platform service, a virtual machine monitor (VMM) services the guest firmware requests for host platform services. Other embodiments are described and claimed.

In general, in one aspect, the disclosure describes a method that includes interrupting a program running on a processor. The active instruction that was interrupted is identified. Event counts since a previous interrupt are harvested.

A processing system may include an operating system (OS) and one or more specialized error handling modules to be registered with the OS after the processing system is powered on. The OS may also include a master policy module. The specialized error handling module may collect error data from a component of the processing system, and may generate abstracted error data, based at least in part on the collected error data. The master policy module may determine a recovery action to be taken, based at least in part on the abstracted error data. The OS may also include an error collection routine that calls one or more specialized error handling modules in response to detecting a hardware error. The error collection routine may also retrieve information from firmware in response to detecting the hardware error. Other embodiments are described and claimed.
