Abstract
A method and system for permitting a guest to program a message-signaled interrupt-based device is disclosed. A hypervisor of a host detects a request by a guest to map an address range of memory of the guest to a message signaled-interrupt capability table associated with a device. The hypervisor maps the message signaled-interrupt capability table from a message signaled-interrupt capability register of a programmable interrupt controller associated with the host to the address range of memory of the guest. The hypervisor detects an attempt by the guest to program the device with the message-signaled interrupt configuration located in the address range of memory of the guest. The hypervisor programs the device with the message-signaled interrupt configuration specified by the guest in the address range of memory of the guest.
