 Driver Load
 -----------
 
-IRQ Registration
-~~~~~~~~~~~~~~~~
 
-The DRM core tries to facilitate IRQ handler registration and
-unregistration by providing :c:func:`drm_irq_install()` and
-:c:func:`drm_irq_uninstall()` functions. Those functions only
-support a single interrupt per device, devices that use more than one
-IRQs need to be handled manually.
+IRQ Helper Library
+~~~~~~~~~~~~~~~~~~
 
-Managed IRQ Registration
-''''''''''''''''''''''''
+.. kernel-doc:: drivers/gpu/drm/drm_irq.c
+   :doc: irq helpers
 
-:c:func:`drm_irq_install()` starts by calling the irq_preinstall
-driver operation. The operation is optional and must make sure that the
-interrupt will not get fired by clearing all pending interrupt flags or
-disabling the interrupt.
-
-The passed-in IRQ will then be requested by a call to
-:c:func:`request_irq()`. If the DRIVER_IRQ_SHARED driver feature
-flag is set, a shared (IRQF_SHARED) IRQ handler will be requested.
-
-The IRQ handler function must be provided as the mandatory irq_handler
-driver operation. It will get passed directly to
-:c:func:`request_irq()` and thus has the same prototype as all IRQ
-handlers. It will get called with a pointer to the DRM device as the
-second argument.
-
-Finally the function calls the optional irq_postinstall driver
-operation. The operation usually enables interrupts (excluding the
-vblank interrupt, which is enabled separately), but drivers may choose
-to enable/disable interrupts at a different time.
-
-:c:func:`drm_irq_uninstall()` is similarly used to uninstall an
-IRQ handler. It starts by waking up all processes waiting on a vblank
-interrupt to make sure they don't hang, and then calls the optional
-irq_uninstall driver operation. The operation must disable all hardware
-interrupts. Finally the function frees the IRQ by calling
-:c:func:`free_irq()`.
-
-Manual IRQ Registration
-'''''''''''''''''''''''
-
-Drivers that require multiple interrupt handlers can't use the managed
-IRQ registration functions. In that case IRQs must be registered and
-unregistered manually (usually with the :c:func:`request_irq()` and
-:c:func:`free_irq()` functions, or their :c:func:`devm_request_irq()` and
-:c:func:`devm_free_irq()` equivalents).
-
-When manually registering IRQs, drivers must not set the
-DRIVER_HAVE_IRQ driver feature flag, and must not provide the
-irq_handler driver operation. They must set the :c:type:`struct
-drm_device <drm_device>` irq_enabled field to 1 upon
-registration of the IRQs, and clear it to 0 after unregistering the
-IRQs.

-Switch to drm_connector_list_iter for any connector_list walking
-----------------------------------------------------------------
-
-Connectors can be hotplugged, and we now have a special list of helpers to walk
-the connector_list in a race-free fashion, without incurring deadlocks on
-mutexes and other fun stuff.
-
-Unfortunately most drivers are not converted yet. At least all those supporting
-DP MST hotplug should be converted, since for those drivers the difference
-matters. See drm_for_each_connector_iter() vs. drm_for_each_connector().

- * drm_crtc_arm_vblank_event - arm vblank event after pageflip
- * @crtc: the source CRTC of the vblank event

- * A lot of drivers need to generate vblank events for the very next vblank
- * interrupt. For example when the page flip interrupt happens when the page
- * flip gets armed, but not when it actually executes within the next vblank
- * period. This helper function implements exactly the required vblank arming
- * behaviour.
- *
- * NOTE: Drivers using this to send out the &drm_crtc_state.event as part of an
- * atomic commit must ensure that the next vblank happens at exactly the same
- * time as the atomic commit is committed to the hardware. This function itself
- * does **not** protect again the next vblank interrupt racing with either this
- * function call or the atomic commit operation. A possible sequence could be:
- *
- * 1. Driver commits new hardware state into vblank-synchronized registers.
- * 2. A vblank happens, committing the hardware state. Also the corresponding
- *    vblank interrupt is fired off and fully processed by the interrupt
- *    handler.
- * 3. The atomic commit operation proceeds to call drm_crtc_arm_vblank_event().
- * 4. The event is only send out for the next vblank, which is wrong.
- *
- * An equivalent race can happen when the driver calls
- * drm_crtc_arm_vblank_event() before writing out the new hardware state.
- *
- * The only way to make this work safely is to prevent the vblank from firing
- * (and the hardware from committing anything else) until the entire atomic
- * commit sequence has run to completion. If the hardware does not have such a
- * feature (e.g. using a "go" bit), then it is unsafe to use this functions.
- * Instead drivers need to manually send out the event from their interrupt
- * handler by calling drm_crtc_send_vblank_event() and make sure that there's no
- * possible race with the hardware committing the atomic update.
- *
- * Caller must hold event lock. Caller must also hold a vblank reference for
- * the event @e, which will be dropped when the next vblank arrives.

+ * A lot of drivers need to generate vblank events for the very next vblank
+ * interrupt. For example when the page flip interrupt happens when the page
+ * flip gets armed, but not when it actually executes within the next vblank
+ * period. This helper function implements exactly the required vblank arming
+ * behaviour.
+ *
+ * NOTE: Drivers using this to send out the &drm_crtc_state.event as part of an
+ * atomic commit must ensure that the next vblank happens at exactly the same
+ * time as the atomic commit is committed to the hardware. This function itself
+ * does **not** protect again the next vblank interrupt racing with either this
+ * function call or the atomic commit operation. A possible sequence could be:
+ *
+ * 1. Driver commits new hardware state into vblank-synchronized registers.
+ * 2. A vblank happens, committing the hardware state. Also the corresponding
+ *    vblank interrupt is fired off and fully processed by the interrupt
+ *    handler.
+ * 3. The atomic commit operation proceeds to call drm_crtc_arm_vblank_event().
+ * 4. The event is only send out for the next vblank, which is wrong.
+ *
+ * An equivalent race can happen when the driver calls
+ * drm_crtc_arm_vblank_event() before writing out the new hardware state.
+ *
+ * The only way to make this work safely is to prevent the vblank from firing
+ * (and the hardware from committing anything else) until the entire atomic
+ * commit sequence has run to completion. If the hardware does not have such a
+ * feature (e.g. using a "go" bit), then it is unsafe to use this functions.
+ * Instead drivers need to manually send out the event from their interrupt
+ * handler by calling drm_crtc_send_vblank_event() and make sure that there's no
+ * possible race with the hardware committing the atomic update.
+ *
+ * Caller must hold event lock. Caller must also hold a vblank reference for
+ * the event @e, which will be dropped when the next vblank arrives.
