int.patch: - Supports only level-triggered interrupts. Edge interrupts support will be added shortly (should be fairly simple) - Change polarity trick: in order to reflect the external device''s assertion state, the ioapic pin gets its polarity changed whenever an interrupt occur. So an interrupt is generated when the _external_ line is asserted (then,

...I read/write functions are similar to other virtual devices. Except write function intercepts writes to COMMAND register and do actual hardware writes. - interrupt virtualization - Currently only works for ACPI/APIC mode - dpci.c makes a hypercall to tell xen device/intx on vPCI - In do_IRQ_guest(), when Xen determines a interrupt belongs to a device owned by HVM domain, it injects guest IRQ to the domain - Revert back to ioapic_ack=old to allow for IRQ sharing amongst guests. - Implemented new method for mask/unmask in io_apic.c to avoid spurious interrupt issue. - mmio - Wh...
