+ 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.

+ <title>Rationale</title>
+ <para>
+ 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.
+ </para>
+ <para>
+ 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:
+ <itemizedlist>
+ <listitem><para>Level type</para></listitem>
+ <listitem><para>Edge type</para></listitem>
+ <listitem><para>Simple type</para></listitem>
+ </itemizedlist>
+ In the SMP world of the __do_IRQ() super-handler another type
+ was identified:
+ <itemizedlist>
+ <listitem><para>Per CPU type</para></listitem>
+ </itemizedlist>
+ </para>
+ <para>
+ 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.
+ </para>
+ <para>
+ 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.
+ </para>
+ <para>
+ A more natural abstraction is the clean separation of the
+ 'irq flow' and the 'chip details'.
+ </para>
+ <para>
+ 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.
+ </para>
+ <para>
+ 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.)
+ </para>
+ <para>
+ 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.
+ </para>
+ <para>
+ 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.

+ 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.)

+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.
