This allows Dom0 to manage physical hardware, redirecting the physical interrupts to event channels. Sponsored by: Citrix Systems R&D x86/xen/xen_intr.c: - Expand struct xenisrc to hold the level and triggering of PIRQ event channels. - Implement missing methods in xen_intr_pirq_pic. - Allow xen_intr_alloc_isrc to take a vector parameter that globally identifies the interrupt. This is only used for PIRQs that are bound to a specific hardware IRQ. - Introduce xen_register_pirq used to register IO APIC legacy PIRQ interrupts. - Add support for the dynamic PIRQ EOI map, this shared memory is modified by Xen (if it suppoorts that feature), and notifies the guest if an EOI is needed or not. If it's not available fall back to the old implementation using PHYSDEVOP_irq_status_query. - Rename xen_intr_isrc_count to xen_intr_auto_vector_count and replace it's usages. - Align static variables by name. xen/xen_intr.h: - Add prototype for xen_register_pirq. |
