| * prevent unbounded stack usage. Whatever the purpose, we expect |
| * that the mask will be asserted only for short periods at a time, |
| * and so the likelihood of a 'spurious' IPI is suitably small. |
| * The mask is read before making an event upcall to the guest: a |
| * non-zero mask therefore guarantees that the VCPU will not receive |
| * an upcall activation. The mask is cleared when the VCPU requests |
| * to block: this avoids wakeup-waiting races. |

| * arrange out-of-band to set up a connection (usually by allocating |
| * an unbound 'listener' port and avertising that via a storage service |
| * such as xenstore). |
| * 2. Physical interrupts. A domain with suitable hardware-access |
| * privileges can bind an event-channel port to a physical interrupt |
| * source. |
| * 3. Virtual interrupts ('events'). A domain can bind an event-channel |
| * port to a virtual interrupt source, such as the virtual-timer |
| * device or the emergency console. |
| * |
| * Event channels are addressed by a "port index". Each channel is |
| * associated with two bits of information: |
| * 1. PENDING -- notifies the domain that there is a pending notification |
| * to be processed. This bit is cleared by the guest. |
| * 2. MASK -- if this bit is clear then a 0->1 transition of PENDING |
| * will cause an asynchronous upcall to be scheduled. This bit is only |
| * updated by the guest. It is read-only within Xen. If a channel |
| * becomes pending while the channel is masked then the 'edge' is lost |
| * (i.e., when the channel is unmasked, the guest must manually handle |
| * pending notifications as no upcall will be scheduled by Xen). |
| * |
| * To expedite scanning of pending notifications, any 0->1 pending |
| * transition on an unmasked channel causes a corresponding bit in a |
| * per-vcpu selector word to be set. Each bit in the selector covers a |
| * 'C long' in the PENDING bitfield array. |
