  "message": "xen: event channels\n\nXen implements interrupts in terms of event channels.  Each guest\ndomain gets 1024 event channels which can be used for a variety of\npurposes, such as Xen timer events, inter-domain events,\ninter-processor events (IPI) or for real hardware IRQs.\n\nWithin the kernel, we map the event channels to IRQs, and implement\nthe whole interrupt handling using a Xen irq_chip.\n\nRather than setting NR_IRQ to 1024 under PARAVIRT in order to\naccomodate Xen, we create a dynamic mapping between event channels and\nIRQs.  Ideally, Linux will eventually move towards dynamically\nallocating per-irq structures, and we can use a 1:1 mapping between\nevent channels and irqs.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Eric W.
