/**client_id; * 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).
