+    <para>
+        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

+    <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.

+        Each interrupt is described by an interrupt descriptor structure

+        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.

+        <para>
+        Whenever an interrupt triggers, the lowlevel arch code calls into

+        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.

+        <title>Delayed interrupt disable</title>
+        <para>
+        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.

+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.

+ * Note: Even though the documentation for the various RTC chips say that it

+   Here's a block diagram of how most of the cards work:
+
+                  +-----------+
+           record |           |<-------------------- Inputs
+          <-------|           |        |
+     PCI          | Transport |        |
+     bus          |  engine   |       \|/
+          ------->|           |    +-------+
+            play  |           |--->|monitor|-------> Outputs
+                  +-----------+    | mixer |
+                                   +-------+
+
+   The lines going to and from the PCI bus represent "pipes".  A pipe performs
+   audio transport - moving audio data to and from buffers on the host via
+   bus mastering.
+
+   The inputs and outputs on the right represent input and output "busses."
+   A bus is a physical, real connection to the outside world.  An example
+   of a bus would be the 1/4" analog connectors on the back of Layla or
+   an RCA S/PDIF connector.
+
+   For most cards, there is a one-to-one correspondence between outputs
+   and busses; that is, each individual pipe is hard-wired to a single bus.
+
+   Cards that work this way are Darla20, Gina20, Layla20, Darla24, Gina24,
+   Layla24, Mona, and Indigo.
+
+
+   Mia has a feature called "virtual outputs."
+
+
+                  +-----------+
+           record |           |<----------------------------- Inputs
+          <-------|           |                  |
+     PCI          | Transport |                  |
+     bus          |  engine   |                 \|/
+          ------->|           |   +------+   +-------+
+            play  |           |-->|vmixer|-->|monitor|-------> Outputs
+                  +-----------+   +------+   | mixer |
+                                             +-------+
+
+
+   Obviously, the difference here is the box labeled "vmixer."  Vmixer is
+   short for "virtual output mixer."  For Mia, pipes are *not* hard-wired
+   to a single bus; the vmixer lets you mix any pipe to any bus in any
+   combination.
+
+   Note, however, that the left-hand side of the diagram is unchanged.
+   Transport works exactly the same way - the difference is in the mixer stage.
+
+
+   Pipes and busses are numbered starting at zero.
+
+
+
+   Pipe index
+   ==========
+
+   A number of calls in CEchoGals refer to a "pipe index".  A pipe index is
+   a unique number for a pipe that unambiguously refers to a playback or record
+   pipe.  Pipe indices are numbered starting with analog outputs, followed by
+   digital outputs, then analog inputs, then digital inputs.
+
+   Take Gina24 as an example:
+
+   Pipe index
+
+   0-7            Analog outputs (0 .. FirstDigitalBusOut-1)
+   8-15           Digital outputs (FirstDigitalBusOut .. NumBussesOut-1)
+   16-17          Analog inputs
+   18-25          Digital inputs
+
+
+   You get the pipe index by calling CEchoGals::OpenAudio; the other transport
+   functions take the pipe index as a parameter.  If you need a pipe index for
+   some other reason, use the handy Makepipe_index method.
+
+
+   Some calls take a CChannelMask parameter; CChannelMask is a handy way to
+   group pipe indices.
+
+
+
+   Digital mode switch
+   ===================
+
+   Some cards (right now, Gina24, Layla24, and Mona) have a Digital Mode Switch
+   or DMS.  Cards with a DMS can be set to one of three mutually exclusive
+   digital modes: S/PDIF RCA, S/PDIF optical, or ADAT optical.
+
+   This may create some confusion since ADAT optical is 8 channels wide and
+   S/PDIF is only two channels wide.  Gina24, Layla24, and Mona handle this
+   by acting as if they always have 8 digital outs and ins.  If you are in
+   either S/PDIF mode, the last 6 channels don't do anything - data sent
+   out these channels is thrown away and you will always record zeros.
+
+   Note that with Gina24, Layla24, and Mona, sample rates above 50 kHz are
+   only available if you have the card configured for S/PDIF optical or S/PDIF
+   RCA.
+
+
+
+   Double speed mode
+   =================
+
+   Some of the cards support 88.2 kHz and 96 kHz sampling (Darla24, Gina24,
+   Layla24, Mona, Mia, and Indigo).  For these cards, the driver sometimes has
+   to worry about "double speed mode"; double speed mode applies whenever the
+   sampling rate is above 50 kHz.
+
+   For instance, Mona and Layla24 support word clock sync.  However, they
+   actually support two different word clock modes - single speed (below
+   50 kHz) and double speed (above 50 kHz).  The hardware detects if a single
+   or double speed word clock signal is present; the generic code uses that
+   information to determine which mode to use.
+
+   The generic code takes care of all this for you.

+
+Setting the sample rates on Layla24 is somewhat schizophrenic.
+
+For standard rates, it works exactly like Mona and Gina24.  That is, for
+8, 11.025, 16, 22.05, 32, 44.1, 48, 88.2, and 96 kHz, you just set the
+appropriate bits in the control register and write the control register.
+
+In order to support MIDI time code sync (and possibly SMPTE LTC sync in
+the future), Layla24 also has "continuous sample rate mode".  In this mode,
+Layla24 can generate any sample rate between 25 and 50 kHz inclusive, or
+50 to 100 kHz inclusive for double speed mode.
+
+To use continuous mode:
+
+-Set the clock select bits in the control register to 0xe (see the #define
+ below)
+
+-Set double-speed mode if you want to use sample rates above 50 kHz
+
+-Write the control register as you would normally
+
+-Now, you need to set the frequency register. First, you need to determine the
+ value for the frequency register.  This is given by the following formula:
+
+frequency_reg = (LAYLA24_MAGIC_NUMBER / sample_rate) - 2
+
+Note the #define below for the magic number
+
+-Wait for the DSP handshake
+-Write the frequency_reg value to the .SampleRate field of the comm page
+-Send the vector command SET_LAYLA24_FREQUENCY_REG (see vmonkey.h)
+
+Once you have set the control register up for continuous mode, you can just
+write the frequency register to change the sample rate.  This could be
+used for MIDI time code sync. For MTC sync, the control register is set for
+continuous mode.  The driver then just keeps writing the
+SET_LAYLA24_FREQUENCY_REG command.
