- * Different ways of handling interrupts. Tile interrupts are always
- * per-cpu; there is no global interrupt controller to implement
- * enable/disable. Most onboard devices can send their interrupts to
- * many tiles at the same time, and Tile-specific drivers know how to
- * deal with this.
- *
- * However, generic devices (usually PCIE based, sometimes GPIO)
- * expect that interrupts will fire on a single core at a time and
- * that the irq can be enabled or disabled from any core at any time.
- * We implement this by directing such interrupts to a single core.
- *
- * One added wrinkle is that PCI interrupts can be either
- * hardware-cleared (legacy interrupts) or software cleared (MSI).
- * Other generic device systems (GPIO) are always software-cleared.
- *
- * The enums below are used by drivers for onboard devices, including
- * the internals of PCI root complex and GPIO. They allow the driver
- * to tell the generic irq code what kind of interrupt is mapped to a
- * particular IRQ number.

- * Paravirtualized drivers should call this when they dynamically
- * allocate a new IRQ or discover an IRQ that was pre-allocated by the
- * hypervisor for use with their particular device. This gives the
- * IRQ subsystem an opportunity to do interrupt-type-specific
- * initialization.
- *
- * ISSUE: We should modify this API so that registering anything
- * except percpu interrupts also requires providing callback methods
- * for enabling and disabling the interrupt. This would allow the
- * generic IRQ code to proxy enable/disable_irq() calls back into the
- * PCI subsystem, which in turn could enable or disable the interrupt
- * at the PCI shim.
