/**
 * DOC: Interrupt Handling
 *
 * Interrupts generated within GPU hardware raise interrupt requests that are
 * passed to amdgpu IRQ handler which is responsible for detecting source and
 * type of the interrupt and dispatching matching handlers. If handling an
 * interrupt requires calling kernel functions that may sleep processing is
 * dispatched to work handlers.
 *
 * If MSI functionality is not disabled by module parameter then MSI
 * support will be enabled.
 *
 * For GPU interrupt sources that may be driven by another driver, IRQ domain
 * support is used (with mapping between virtual and hardware IRQs).
