+ select SND_PCM
+ help
+ If you don't have a sound card in your computer, you can include a
+ driver for the PC speaker which allows it to act like a primitive
+ sound card.
+ This driver also replaces the pcspkr driver for beeps.
+
+ You can compile this as a module which will be called snd-pcsp.
+
+ WARNING: if you already have a soundcard, enabling this
+ driver may lead to a problem. Namely, it may get loaded
+ before the other sound driver of yours, making the
+ pc-speaker a default sound device. Which is likely not
+ what you want. To make this driver play nicely with other
+ sound driver, you can add this in a configuration file under
+ /etc/modprobe.d/ directory:
+ options snd-pcsp index=2
+
+ You don't need this driver if you only want your pc-speaker to beep.
+ You don't need this driver if you have a tablet piezo beeper
+ in your PC instead of the real speaker.
+
+ Say N if you have a sound card.
+ Say M if you don't.
+ Say Y only if you really know what you do.
+
+config SND_DUMMY
+ tristate "Dummy (/dev/null) soundcard"
+ select SND_PCM
+ help
+ Say Y here to include the dummy driver. This driver does
+ nothing, but emulates various mixer controls and PCM devices.
+
+ You don't need this unless you're testing the hardware support
+ of programs using the ALSA API.
+
+ To compile this driver as a module, choose M here: the module
+ will be called snd-dummy.
+
+config SND_ALOOP
+ tristate "Generic loopback driver (PCM)"
+ select SND_PCM
+ help
+ Say 'Y' or 'M' to include support for the PCM loopback device.
+ This module returns played samples back to the user space using
+ the standard ALSA PCM device. The devices are routed 0->1 and
+ 1->0, where first number is the playback PCM device and second
+ number is the capture device. Module creates two PCM devices and
+ configured number of substreams (see the pcm_substreams module
+ parameter).
+
+ The looback device allow time sychronization with an external
+ timing source using the time shift universal control (+-20%
+ of system time).
+

+ will be called snd-aloop.

+ sequencer clients.

+ will be called snd-mts64.
+

+ select SND_RAWMIDI
+ help
+ To include support for MIDI serial port interfaces, say Y here
+ and read <file:Documentation/sound/alsa/serial-u16550.txt>.
+ This driver works with serial UARTs 16550 and better.
+
+ This driver accesses the serial port hardware directly, so
+ make sure that the standard serial driver isn't used or
+ deactivated with setserial before loading this driver.
+
+ To compile this driver as a module, choose M here: the module
+ will be called snd-serial-u16550.
+
+config SND_MPU401

+ will be called snd-mpu401.
+

+
+config SND_AC97_POWER_SAVE
+ bool "AC97 Power-Saving Mode"
+ depends on SND_AC97_CODEC
+ default n
+ help
+ Say Y here to enable the aggressive power-saving support of
+ AC97 codecs. In this mode, the power-mode is dynamically
+ controlled at each open/close.
+
+ The mode is activated by passing 'power_save=X' to the
+ snd-ac97-codec driver module, where 'X' is the time-out
+ value, a nonnegative integer that specifies how many
+ seconds of idle time the driver must count before it may
+ put the AC97 into power-save mode; a value of 0 (zero)
+ disables the use of this power-save mode.
+
+ After the snd-ac97-codec driver module has been loaded,
+ the 'power_save' parameter can be set via sysfs as follows:
+
+ echo 10 > /sys/module/snd_ac97_codec/parameters/power_save
+
+ In this case, the time-out is set to 10 seconds; setting
+ the time-out to 1 second (the minimum activation value)
+ isn't recommended because many applications try to reopen
+ the device frequently. A value of 10 seconds would be a
+ good choice for normal operations.
+
+ See Documentation/sound/alsa/powersave.txt for more details.
+
+config SND_AC97_POWER_SAVE_DEFAULT
+ int "Default time-out for AC97 power-save mode"
+ depends on SND_AC97_POWER_SAVE
+ default 0
+ help
+ The default time-out value in seconds for AC97 automatic
+ power-save mode. 0 means to disable the power-save mode.
+
+ See SND_AC97_POWER_SAVE for more details.

+/* Some notes / status of this driver:
+ *
+ * - Don't wonder about some strange implementations of things - especially the
+ * (heavy) shadowing of codec registers, with which I tried to reduce read
+ * accesses to a minimum, because after a variable amount of accesses, the AC97
+ * controller doesn't raise the register access finished bit anymore ...
+ *
+ * - Playback support seems to be pretty stable - no issues here.
+ * - Capture support "works" now, too. Overruns don't happen any longer so often.
+ * But there might still be some ...

+ * This driver is for the 'Mark Of The Unicorn' (MOTU)
+ * MidiTimePiece AV multiport MIDI interface
+ *
+ * IOPORTS
+ * -------
+ * 8 MIDI Ins and 8 MIDI outs
+ * Video Sync In (BNC), Word Sync Out (BNC),
+ * ADAT Sync Out (DB9)
+ * SMPTE in/out (1/4")
+ * 2 programmable pedal/footswitch inputs and 4 programmable MIDI controller knobs.
+ * Macintosh RS422 serial port
+ * RS422 "network" port for ganging multiple MTP's
+ * PC Parallel Port ( which this driver currently uses )
+ *
+ * MISC FEATURES
+ * -------------
+ * Hardware MIDI routing, merging, and filtering
+ * MIDI Synchronization to Video, ADAT, SMPTE and other Clock sources
+ * 128 'scene' memories, recallable from MIDI program change
+ *
+ *
+ * ChangeLog
+ * Jun 11 2001 Takashi Iwai <tiwai@suse.de>
+ * - Recoded & debugged
+ * - Added timer interrupt for midi outputs
+ * - hwports is between 1 and 8, which specifies the number of hardware ports.
+ * The three global ports, computer, adat and broadcast ports, are created
+ * always after h/w and remote ports.

+ * For a Rx interrupt, this is done by reading the received byte.
+ * For a Tx interrupt this is done by either:
+ * a) Writing a byte
+ * b) Reading the IIR
+ * It is particularly important to read the IIR if a Tx interrupt is received
+ * when there is no data in tx_buff[], as in this case there no other
+ * indication that the interrupt has been serviced, and it remains outstanding
+ * indefinitely. This has the curious side effect that and no further interrupts
+ * will be generated from this device AT ALL!!.
+ * It is also desirable to clear outstanding interrupts when the device is
+ * opened/closed.
+ *
+ *
+ * Note that some devices need OUT2 to be set before they will generate
+ * interrupts at all. (Possibly tied to an internal pull-up on CTS?)

+ * VIRTUAL RAW MIDI DEVICE CARDS
+ *
+ * This dummy card contains up to 4 virtual rawmidi devices.
+ * They are not real rawmidi devices but just associated with sequencer
+ * clients, so that any input/output sources can be connected as a raw
+ * MIDI device arbitrary.
+ * Also, multiple access is allowed to a single rawmidi device.
+ *
+ * Typical usage is like following:
+ * - Load snd-virmidi module.
+ * # modprobe snd-virmidi index=2
+ * Then, sequencer clients 72:0 to 75:0 will be created, which are
+ * mapped from /dev/snd/midiC1D0 to /dev/snd/midiC1D3, respectively.
+ *
+ * - Connect input/output via aconnect.
+ * % aconnect 64:0 72:0 # keyboard input redirection 64:0 -> 72:0
+ * % aconnect 72:0 65:0 # output device redirection 72:0 -> 65:0
+ *
+ * - Run application using a midi device (eg. /dev/snd/midiC1D0)

+ * STRATEGY
+ * for playback, we send series of "chunks", which size is equal with the
+ * IBL size, typically 126 samples. at each end of chunk, the end-of-buffer
+ * interrupt is notified, and the interrupt handler will feed the next chunk.
+ *
+ * the current position is calculated from the sample count RMH.
+ * pipe->transferred is the counter of data which has been already transferred.
+ * if this counter reaches to the period size, snd_pcm_period_elapsed() will
+ * be issued.
+ *
+ * for capture, the situation is much easier.
+ * to get a low latency response, we'll check the capture streams at each
+ * interrupt (capture stream has no EOB notification). if the pending
+ * data is accumulated to the period size, snd_pcm_period_elapsed() is
+ * called and the pointer is updated.
+ *
+ * the current point of read buffer is kept in pipe->hw_ptr. note that
+ * this is in bytes.
+ *
+ *
+ * TODO
+ * - linked trigger for full-duplex mode.
+ * - scheduled action on the stream.
