摘要:
Embodiments of apparatuses, methods, and systems for controlling virtual machines based on activity state are disclosed. In one embodiment, an apparatus includes virtual machine entry logic and activity state evaluation logic. The virtual machine entry logic is to transfer control of the apparatus from a host to a guest. The activity state evaluation logic is to determine whether the activity state of the guest would be inactive upon receiving control.

A apparatus is disclosed. The apparatus includes a remapping circuit to facilitate access of one or more I/O devices to a memory device for direct memory access (DMA) transactions. The remapping circuit includes a translation mechanism to perform memory address translations for I/O DMA transactions via address window-based translations.

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 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 a guest.

In one embodiment, an apparatus includes a set of multiplex blocks coupled with an interrupt controller and multiple interrupt request lines, and a virtual machine monitor block (VMM) coupled to the set of multiplex blocks. Each multiplex block corresponds to a distinct interrupt request line. Each multiplex block is to route the interrupt request signal received via the corresponding interrupt request line either to the interrupt controller or the VMM block depending on a current configuration value of this multiplex block.

In one embodiment, a request to transition control to a virtual machine (VM) is received from a virtual machine monitor (VMM) and a determination is made as to whether the VMM has requested a delivery of a fault to the VM. If the determination is positive, the fault is delivered to the VM when control is transitioned to the VM.

Embodiments of apparatuses, methods, and systems for injecting virtualization events in a layered virtualization architecture are disclosed. In one embodiment, an apparatus includes virtual machine entry logic, recognition logic, and evaluation logic. The virtual machine entry logic is to initiate a transfer of control of the apparatus from a host to a guest running on a virtual machine. The recognition logic is to recognize a request from the host to inject a virtualization event into the virtual machine. The evaluation logic is to identify an intervening monitor to handle the virtualization event.
