Abstract: Embodiments of apparatuses, methods, and systems for virtualizing performance counters are disclosed. In one embodiment, an apparatus includes a counter, a counter enable storage location, counter enable logic, and virtual machine control logic. The counter enable storage location is to store a counter enable indicator. The counter enable logic is to enable the counter based on the counter enable indicator. The virtual machine control logic is to transfer control of the apparatus to a guest. The virtual machine control logic includes guest state load logic to cause a guest value from a virtual machine control structure to be loaded into the counter enable storage location in connection with a transfer of control of the apparatus to the guest.

Abstract: According to an embodiment of the invention, a method for operating a data processing machine is described in which data about a state of the machine is written to a location in storage. The location is one that is accessible to software that may be written for the machine. The state data as written is encoded. This state data may be recovered from the storage according to a decoding process. Other embodiments are also described and claimed.
