zx_status_t Init (PipeVsyncCallback pipe_vsync_callback, HotplugCallback hotplug_callback, const ddk::Pci & pci, fdf::MmioBuffer * mmio_space, uint16_t device_id)

Must be called exactly once.

Must be called from a driver-runtime managed dispatcher.

`mmio_space` must be non-null and outlive the initialized `Interrupts`

instance.

void EnablePipeInterrupts (PipeId pipe_id, bool enable)

Enable or disable interrupt generation from `pipe`.

This method enables and disables all the pipe-level interrupts that we are

prepared to handle.

Transcoder VSync (vertical sync) interrupts trigger callbacks to the

PipeVsyncCallback provided to `Init()`. The callbacks are performed on the

internal thread dedicated to interrupt handling.

zx_status_t SetGpuInterruptCallback (const intel_gpu_core_interrupt_t & gpu_interrupt_callback, uint32_t gpu_interrupt_mask)

The GPU driver uses this to plug into the interrupt stream.

On Tiger Lake, `gpu_callback` will be called during an interrupt

from the graphics hardware if the Graphics Primary Interrupt register

indicates there are GT interrupts pending.

On Skylake and Kaby Lake, `gpu_callback` will be called during an interrupt

from the graphics hardware if the Display Interrupt Control register has

any bits in `gpu_interrupt_mask` set.
