+ Introduction
+
+ The generic interrupt handling layer is designed to provide a
+ complete abstraction of interrupt handling for device drivers.
+ It is able to handle all the different types of interrupt controller
+ hardware. Device drivers use generic API functions to request, enable,
+ disable and free interrupts. The drivers do not have to know anything
+ about interrupt hardware details, so they can be used on different
+ platforms without code changes.
+
+
+ This documentation is provided to developers who want to implement
+ an interrupt subsystem based for their architecture, with the help
+ of the generic IRQ handling layer.
+
+
+
+
+ Rationale
+
+ The original implementation of interrupt handling in Linux is using
+ the __do_IRQ() super-handler, which is able to deal with every
+ type of interrupt logic.
+
+
+ Originally, Russell King identified different types of handlers to
+ build a quite universal set for the ARM interrupt handler
+ implementation in Linux 2.5/2.6. He distinguished between:
+
+ Level type
+ Edge type
+ Simple type
+
+ In the SMP world of the __do_IRQ() super-handler another type
+ was identified:
+
+ Per CPU type
+
+
+
+ This split implementation of highlevel IRQ handlers allows us to
+ optimize the flow of the interrupt handling for each specific
+ interrupt type. This reduces complexity in that particular codepath
+ and allows the optimized handling of a given type.
+
+
+ The original general IRQ implementation used hw_interrupt_type
+ structures and their ->ack(), ->end() [etc.] callbacks to
+ differentiate the flow control in the super-handler. This leads to
+ a mix of flow logic and lowlevel hardware logic, and it also leads
+ to unnecessary code duplication: for example in i386, there is a
+ ioapic_level_irq and a ioapic_edge_irq irq-type which share many
+ of the lowlevel details but have different flow handling.
+
+
+ A more natural abstraction is the clean separation of the
+ 'irq flow' and the 'chip details'.
+
+
+ Analysing a couple of architecture's IRQ subsystem implementations
+ reveals that most of them can use a generic set of 'irq flow'
+ methods and only need to add the chip level specific code.
+ The separation is also valuable for (sub)architectures
+ which need specific quirks in the irq flow itself but not in the
+ chip-details - and thus provides a more transparent IRQ subsystem
+ design.
+
+
+ Each interrupt descriptor is assigned its own highlevel flow
+ handler, which is normally one of the generic
+ implementations. (This highlevel flow handler implementation also
+ makes it simple to provide demultiplexing handlers which can be
+ found in embedded platforms on various architectures.)
+
+
+ The separation makes the generic interrupt handling layer more
+ flexible and extensible. For example, an (sub)architecture can
+ use a generic irq-flow implementation for 'level type' interrupts
+ and add a (sub)architecture specific 'edge type' implementation.
+
+
+ To make the transition to the new model easier and prevent the
+ breakage of existing implementations, the __do_IRQ() super-handler
+ is still available. This leads to a kind of duality for the time
+ being. Over time the new model should be used in more and more
+ architectures, as it enables smaller and cleaner IRQ subsystems.
+
+
+
+ Known Bugs And Assumptions
+
+ None (knock on wood).
+
+
+
+
+ Abstraction layers
+
+ There are three main levels of abstraction in the interrupt code:
+
+ Highlevel driver API
+ Highlevel IRQ flow handlers
+ Chiplevel hardware encapsulation
+
+
+
+ Interrupt control flow
+
+ Each interrupt is described by an interrupt descriptor structure
+ irq_desc. The interrupt is referenced by an 'unsigned int' numeric
+ value which selects the corresponding interrupt decription structure
+ in the descriptor structures array.
+ The descriptor structure contains status information and pointers
+ to the interrupt flow method and the interrupt chip structure
+ which are assigned to this interrupt.
+
+
+ Whenever an interrupt triggers, the lowlevel arch code calls into
+ the generic interrupt code by calling desc->handle_irq().
+ This highlevel IRQ handling function only uses desc->chip primitives
+ referenced by the assigned chip descriptor structure.
+
+
+
+ Highlevel Driver API
+
+ The highlevel Driver API consists of following functions:
+
+ request_irq()
+ free_irq()
+ disable_irq()
+ enable_irq()
+ disable_irq_nosync() (SMP only)
+ synchronize_irq() (SMP only)
+ set_irq_type()
+ set_irq_wake()
+ set_irq_data()
+ set_irq_chip()
+ set_irq_chip_data()
+
+ See the autogenerated function documentation for details.
+
+
+
+ Highlevel IRQ flow handlers
+
+ The generic layer provides a set of pre-defined irq-flow methods:
+
+ handle_level_irq
+ handle_edge_irq
+ handle_simple_irq
+ handle_percpu_irq
+
+ The interrupt flow handlers (either predefined or architecture
+ specific) are assigned to specific interrupts by the architecture
+ either during bootup or during device initialization.
+
+
+ Default flow implementations
+
+ Helper functions
+
+ The helper functions call the chip primitives and
+ are used by the default flow implementations.
+ The following helper functions are implemented (simplified excerpt):
+
+default_enable(irq)
+{
+ desc->chip->unmask(irq);
+}
+
+default_disable(irq)
+{
+ if (!delay_disable(irq))
+ desc->chip->mask(irq);
+}
+
+default_ack(irq)
+{
+ chip->ack(irq);
+}
+
+default_mask_ack(irq)
+{
+ if (chip->mask_ack) {
+ chip->mask_ack(irq);
+ } else {
+ chip->mask(irq);
+ chip->ack(irq);
+ }
+}
+
+noop(irq)
+{
+}
+
+
+
+
+
+
+ Default flow handler implementations
+
+ Default Level IRQ flow handler
+
+ handle_level_irq provides a generic implementation
+ for level-triggered interrupts.
+
+
+ The following control flow is implemented (simplified excerpt):
+
+desc->chip->start();
+handle_IRQ_event(desc->action);
+desc->chip->end();
+
+
+
+
+ Default Edge IRQ flow handler
+
+ handle_edge_irq provides a generic implementation
+ for edge-triggered interrupts.
+
+
+ The following control flow is implemented (simplified excerpt):
+
+if (desc->status & running) {
+ desc->chip->hold();
+ desc->status |= pending | masked;
+ return;
+}
+desc->chip->start();
+desc->status |= running;
+do {
+ if (desc->status & masked)
+ desc->chip->enable();
+ desc-status &= ~pending;
+ handle_IRQ_event(desc->action);
+} while (status & pending);
+desc-status &= ~running;
+desc->chip->end();
+
+
+
+
+ Default simple IRQ flow handler
+
+ handle_simple_irq provides a generic implementation
+ for simple interrupts.
+
+
+ Note: The simple flow handler does not call any
+ handler/chip primitives.
+
+
+ The following control flow is implemented (simplified excerpt):
+
+handle_IRQ_event(desc->action);
+
+
+
+
+ Default per CPU flow handler
+
+ handle_percpu_irq provides a generic implementation
+ for per CPU interrupts.
+
+
+ Per CPU interrupts are only available on SMP and
+ the handler provides a simplified version without
+ locking.
+
+
+ The following control flow is implemented (simplified excerpt):
+
+desc->chip->start();
+handle_IRQ_event(desc->action);
+desc->chip->end();
+
+
+
+
+
+ Quirks and optimizations
+
+ The generic functions are intended for 'clean' architectures and chips,
+ which have no platform-specific IRQ handling quirks. If an architecture
+ needs to implement quirks on the 'flow' level then it can do so by
+ overriding the highlevel irq-flow handler.
+
+
+
+ Delayed interrupt disable
+
+ This per interrupt selectable feature, which was introduced by Russell
+ King in the ARM interrupt implementation, does not mask an interrupt
+ at the hardware level when disable_irq() is called. The interrupt is
+ kept enabled and is masked in the flow handler when an interrupt event
+ happens. This prevents losing edge interrupts on hardware which does
+ not store an edge interrupt event while the interrupt is disabled at
+ the hardware level. When an interrupt arrives while the IRQ_DISABLED
+ flag is set, then the interrupt is masked at the hardware level and
+ the IRQ_PENDING bit is set. When the interrupt is re-enabled by
+ enable_irq() the pending bit is checked and if it is set, the
+ interrupt is resent either via hardware or by a software resend
+ mechanism. (It's necessary to enable CONFIG_HARDIRQS_SW_RESEND when
+ you want to use the delayed interrupt disable feature and your
+ hardware is not capable of retriggering an interrupt.)
+ The delayed interrupt disable can be runtime enabled, per interrupt,
+ by setting the IRQ_DELAYED_DISABLE flag in the irq_desc status field.
+
+
+
+
+ Chiplevel hardware encapsulation
+
+ The chip level hardware descriptor structure irq_chip
+ contains all the direct chip relevant functions, which
+ can be utilized by the irq flow implementations.
+
+ ack()
+ mask_ack() - Optional, recommended for performance
+ mask()
+ unmask()
+ retrigger() - Optional
+ set_type() - Optional
+ set_wake() - Optional
+
+ These primitives are strictly intended to mean what they say: ack means
+ ACK, masking means masking of an IRQ line, etc. It is up to the flow
+ handler(s) to use these basic units of lowlevel functionality.
+
+
+
+
+
+ __do_IRQ entry point
+
+ The original implementation __do_IRQ() is an alternative entry
+ point for all types of interrupts.
+
+
+ This handler turned out to be not suitable for all
+ interrupt hardware and was therefore reimplemented with split
+ functionality for egde/level/simple/percpu interrupts. This is not
+ only a functional optimization. It also shortens code paths for
+ interrupts.
+
+
+ To make use of the split implementation, replace the call to
+ __do_IRQ by a call to desc->chip->handle_irq() and associate
+ the appropriate handler function to desc->chip->handle_irq().
+ In most cases the generic handler implementations should
+ be sufficient.
+
+
+
+
+ Locking on SMP
+
+ The locking of chip registers is up to the architecture that
+ defines the chip primitives. There is a chip->lock field that can be used
+ for serialization, but the generic layer does not touch it. The per-irq
+ structure is protected via desc->lock, by the generic layer.

+What is an IRQ?
+
+An IRQ is an interrupt request from a device.
+Currently they can come in over a pin, or over a packet.
+Several devices may be connected to the same pin thus
+sharing an IRQ.
+
+An IRQ number is a kernel identifier used to talk about a hardware
+interrupt source. Typically this is an index into the global irq_desc
+array, but except for what linux/interrupt.h implements the details
+are architecture specific.
+
+An IRQ number is an enumeration of the possible interrupt sources on a
+machine. Typically what is enumerated is the number of input pins on
+all of the interrupt controller in the system. In the case of ISA
+what is enumerated are the 16 input pins on the two i8259 interrupt
+controllers.
+
+Architectures can assign additional meaning to the IRQ numbers, and
+are encouraged to in the case where there is any manual configuration
+of the hardware involved. The ISA IRQs are a classic example of
+assigning this kind of additional meaning.
