/**
* DOC: overview
*
* DM provides another layer of IRQ management on top of what the base driver
* already provides. This is something that could be cleaned up, and is a
* future TODO item.
*
* The base driver provides IRQ source registration with DRM, handler
* registration into the base driver's IRQ table, and a handler callback
* amdgpu_irq_handler(), with which DRM calls on interrupts. This generic
* handler looks up the IRQ table, and calls the respective
* &amdgpu_irq_src_funcs.process hookups.
*
* What DM provides on top are two IRQ tables specifically for top-half and
* bottom-half IRQ handling, with the bottom-half implementing workqueues:
*
* - &amdgpu_display_manager.irq_handler_list_high_tab
* - &amdgpu_display_manager.irq_handler_list_low_tab
*
* They override the base driver's IRQ table, and the effect can be seen
* in the hooks that DM provides for &amdgpu_irq_src_funcs.process. They
* are all set to the DM generic handler amdgpu_dm_irq_handler(), which looks up
* DM's IRQ tables. However, in order for base driver to recognize this hook, DM
* still needs to register the IRQ with the base driver. See
* dce110_register_irq_handlers() and dcn10_register_irq_handlers().
*
* To expose DC's hardware interrupt toggle to the base driver, DM implements
* &amdgpu_irq_src_funcs.set hooks. Base driver calls it through
* amdgpu_irq_update() to enable or disable the interrupt.
