- Installing and using Creative AWE midi sound under Linux.
-
-This documentation is devoted to the Creative Sound Blaster AWE32, AWE64 and
-SB32.
-
-1) Make sure you have an ORIGINAL Creative SB32, AWE32 or AWE64 card. This
- is important, because the driver works only with real Creative cards.
-
-2) The first thing you need to do is re-compile your kernel with support for
- your sound card. Run your favourite tool to configure the kernel and when
- you get to the "Sound" menu you should enable support for the following:
-
- Sound card support,
- OSS sound modules,
- 100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support,
- AWE32 synth
-
- If your card is "Plug and Play" you will also need to enable these two
- options, found under the "Plug and Play configuration" menu:
-
- Plug and Play support
- ISA Plug and Play support
-
- Now compile and install the kernel in normal fashion. If you don't know
- how to do this you can find instructions for this in the README file
- located in the root directory of the kernel source.
-
-3) Before you can start playing midi files you will have to load a sound
- bank file. The utility needed for doing this is called "sfxload", and it
- is one of the utilities found in a package called "awesfx". If this
- package is not available in your distribution you can download the AWE
- snapshot from Creative Labs Open Source website:
-
- http://www.opensource.creative.com/snapshot.html
-
- Once you have unpacked the AWE snapshot you will see a "awesfx"
- directory. Follow the instructions in awesfx/docs/INSTALL to install the
- utilities in this package. After doing this, sfxload should be installed
- as:
-
- /usr/local/bin/sfxload
-
- To enable AWE general midi synthesis you should also get the sound bank
- file for general midi from:
-
- http://members.xoom.com/yar/synthgm.sbk.gz
-
- Copy it to a directory of your choice, and unpack it there.
-
-4) Edit /etc/modprobe.conf, and insert the following lines at the end of the
- file:
-
- alias sound-slot-0 sb
- alias sound-service-0-1 awe_wave
- install awe_wave /sbin/modprobe --first-time -i awe_wave && /usr/local/bin/sfxload PATH_TO_SOUND_BANK_FILE
-
- You will of course have to change "PATH_TO_SOUND_BANK_FILE" to the full
- path of the sound bank file. That will enable the Sound Blaster and AWE
- wave synthesis. To play midi files you should get one of these programs if
- you don't already have them:
-
- Playmidi: http://playmidi.openprojects.net
-
- AWEMidi Player (drvmidi) Included in the previously mentioned AWE
- snapshot.
-
- You will probably have to pass the "-e" switch to playmidi to have it use
- your midi device. drvmidi should work without switches.
-
- If something goes wrong please e-mail me. All comments and suggestions are
- welcome.

- INSTALLATION OF AWE32 SOUND DRIVER FOR LINUX
- Takashi Iwai <iwai@ww.uni-erlangen.de>
-================================================================
-
-----------------------------------------------------------------
-* Attention to SB-PnP Card Users
-
-If you're using PnP cards, the initialization of PnP is required
-before loading this driver. You have now three options:
- 1. Use isapnptools.
- 2. Use in-kernel isapnp support.
- 3. Initialize PnP on DOS/Windows, then boot linux by loadlin.
-In this document, only the case 1 case is treated.
-
-----------------------------------------------------------------
-* Installation on Red Hat 5.0 Sound Driver
-
-Please use install-rh.sh under RedHat5.0 directory.
-DO NOT USE install.sh below.
-See INSTALL.RH for more details.
-
-----------------------------------------------------------------
-* Installation/Update by Shell Script
-
- 1. Become root
-
- % su
-
- 2. If you have never configured the kernel tree yet, run make config
- once (to make dependencies and symlinks).
-
- # cd /usr/src/linux
- # make xconfig
-
- 3. Run install.sh script
-
- # sh ./install.sh
-
- 4. Configure your kernel
-
- (for Linux 2.[01].x user)
- # cd /usr/src/linux
- # make xconfig (or make menuconfig)
-
- (for Linux 1.2.x user)
- # cd /usr/src/linux
- # make config
-
- Answer YES to both "lowlevel drivers" and "AWE32 wave synth" items
- in Sound menu. ("lowlevel drivers" will appear only in 2.x
- kernel.)
-
- 5. Make your kernel (and modules), and install them as usual.
-
- 5a. make kernel image
- # make zImage
-
- 5b. make modules and install them
- # make modules && make modules_install
-
- 5c. If you're using lilo, copy the kernel image and run lilo.
- Otherwise, copy the kernel image to suitable directory or
- media for your system.
-
- 6. Reboot the kernel if necessary.
- - If you updated only the modules, you don't have to reboot
- the system. Just remove the old sound modules here.
- in
- # rmmod sound.o (linux-2.0 or OSS/Free)
- # rmmod awe_wave.o (linux-2.1)
-
- 7. If your AWE card is a PnP and not initialized yet, you'll have to
- do it by isapnp tools. Otherwise, skip to 8.
-
- This section described only a brief explanation. For more
- details, please see the AWE64-Mini-HOWTO or isapnp tools FAQ.
-
- 7a. If you have no isapnp.conf file, generate it by pnpdump.
- Otherwise, skip to 7d.
- # pnpdump > /etc/isapnp.conf
-
- 7b. Edit isapnp.conf file. Comment out the appropriate
- lines containing desirable I/O ports, DMA and IRQs.
- Don't forget to enable (ACT Y) line.
-
- 7c. Add two i/o ports (0xA20 and 0xE20) in WaveTable part.
- ex)
- (CONFIGURE CTL0048/58128 (LD 2
- # ANSI string -->WaveTable<--
- (IO 0 (BASE 0x0620))
- (IO 1 (BASE 0x0A20))
- (IO 2 (BASE 0x0E20))
- (ACT Y)
- ))
-
- 7d. Load the config file.
- CAUTION: This will reset all PnP cards!
-
- # isapnp /etc/isapnp.conf
-
- 8. Load the sound module (if you configured it as a module):
-
- for 2.0 kernel or OSS/Free monolithic module:
-
- # modprobe sound.o
-
- for 2.1 kernel:
-
- # modprobe sound
- # insmod uart401
- # insmod sb io=0x220 irq=5 dma=1 dma16=5 mpu_io=0x330
- (These values depend on your settings.)
- # insmod awe_wave
- (Be sure to load awe_wave after sb!)
-
- See Documentation/sound/oss/AWE32 for
- more details.
-
- 9. (only for obsolete systems) If you don't have /dev/sequencer
- device file, make it according to Readme.linux file on
- /usr/src/linux/drivers/sound. (Run a shell script included in
- that file). <-- This file no longer exists in the recent kernels!
-
- 10. OK, load your own soundfont file, and enjoy MIDI!
-
- % sfxload synthgm.sbk
- % drvmidi foo.mid
-
- 11. For more advanced use (eg. dynamic loading, virtual bank and
- etc.), please read the awedrv FAQ or the instructions in awesfx
- and awemidi packages.
-
-Good luck!

- An OSS/Lite Driver for the ESS Maestro family of sound cards
-
- Zach Brown, December 1999
-
-Driver Status and Availability
-------------------------------
-
-The most recent version of this driver will hopefully always be available at
- http://www.zabbo.net/maestro/
-
-I will try and maintain the most recent stable version of the driver
-in both the stable and development kernel lines.
-
-ESS Maestro Chip Family
------------------------
-
-There are 3 main variants of the ESS Maestro PCI sound chip. The first
-is the Maestro 1. It was originally produced by Platform Tech as the
-'AGOGO'. It can be recognized by Platform Tech's PCI ID 0x1285 with
-0x0100 as the device ID. It was put on some sound boards and a few laptops.
-ESS bought the design and cleaned it up as the Maestro 2. This starts
-their marking with the ESS vendor ID 0x125D and the 'year' device IDs.
-The Maestro 2 claims 0x1968 while the Maestro 2e has 0x1978.
-
-The various families of Maestro are mostly identical as far as this
-driver is concerned. It doesn't touch the DSP parts that differ (though
-it could for FM synthesis).
-
-Driver OSS Behavior
---------------------
-
-This OSS driver exports /dev/mixer and /dev/dsp to applications, which
-mostly adhere to the OSS spec. This driver doesn't register itself
-with /dev/sndstat, so don't expect information to appear there.
-
-The /dev/dsp device exported behaves almost as expected. Playback is
-supported in all the various lovely formats. 8/16bit stereo/mono from
-8khz to 48khz, and mmap()ing for playback behaves. Capture/recording
-is limited due to oddities with the Maestro hardware. One can only
-record in 16bit stereo. For recording the maestro uses non interleaved
-stereo buffers so that mmap()ing the incoming data does not result in
-a ring buffer of LRLR data. mmap()ing of the read buffers is therefore
-disallowed until this can be cleaned up.
-
-/dev/mixer is an interface to the AC'97 codec on the Maestro. It is
-worth noting that there are a variety of AC'97s that can be wired to
-the Maestro. Which is used is entirely up to the hardware implementor.
-This should only be visible to the user by the presence, or lack, of
-'Bass' and 'Treble' sliders in the mixer. Not all AC'97s have them.
-
-The driver doesn't support MIDI or FM playback at the moment. Typically
-the Maestro is wired to an MPU MIDI chip, but some hardware implementations
-don't. We need to assemble a white list of hardware implementations that
-have MIDI wired properly before we can claim to support it safely.
-
-Compiling and Installing
-------------------------
-
-With the drivers inclusion into the kernel, compiling and installing
-is the same as most OSS/Lite modular sound drivers. Compilation
-of the driver is enabled through the CONFIG_SOUND_MAESTRO variable
-in the config system.
-
-It may be modular or statically linked. If it is modular it should be
-installed with the rest of the modules for the kernel on the system.
-Typically this will be in /lib/modules/ somewhere. 'alias sound maestro'
-should also be added to your module configs (typically /etc/conf.modules)
-if you're using modular OSS/Lite sound and want to default to using a
-maestro chip.
-
-As this is a PCI device, the module does not need to be informed of
-any IO or IRQ resources it should use, it devines these from the
-system. Sometimes, on sucky PCs, the BIOS fails to allocated resources
-for the maestro. This will result in a message like:
- maestro: PCI subsystem reports IRQ 0, this might not be correct.
-from the kernel. Should this happen the sound chip most likely will
-not operate correctly. To solve this one has to dig through their BIOS
-(typically entered by hitting a hot key at boot time) and figure out
-what magic needs to happen so that the BIOS will reward the maestro with
-an IRQ. This operation is incredibly system specific, so you're on your
-own. Sometimes the magic lies in 'PNP Capable Operating System' settings.
-
-There are very few options to the driver. One is 'debug' which will
-tell the driver to print minimal debugging information as it runs. This
-can be collected with 'dmesg' or through the klogd daemon.
-
-The other, more interesting option, is 'dsps_order'. Typically at
-install time the driver will only register one available /dev/dsp device
-for its use. The 'dsps_order' module parameter allows for more devices
-to be allocated, as a power of two. Up to 4 devices can be registered
-( dsps_order=2 ). These devices act as fully distinct units and use
-separate channels in the maestro.
-
-Power Management
-----------------
-
-As of version 0.14, this driver has a minimal understanding of PCI
-Power Management. If it finds a valid power management capability
-on the PCI device it will attempt to use the power management
-functions of the maestro. It will only do this on Maestro 2Es and
-only on machines that are known to function well. You can
-force the use of power management by setting the 'use_pm' module
-option to 1, or can disable it entirely by setting it to 0.
-
-When using power management, the driver does a few things
-differently. It will keep the chip in a lower power mode
-when the module is inserted but /dev/dsp is not open. This
-allows the mixer to function but turns off the clocks
-on other parts of the chip. When /dev/dsp is opened the chip
-is brought into full power mode, and brought back down
-when it is closed. It also powers down the chip entirely
-when the module is removed or the machine is shutdown. This
-can have nonobvious consequences. CD audio may not work
-after a power managing driver is removed. Also, software that
-doesn't understand power management may not be able to talk
-to the powered down chip until the machine goes through a hard
-reboot to bring it back.

- An OSS/Lite Driver for the ESS Maestro3 family of sound chips
-
- Zach Brown, January 2001
-
-Driver Status and Availability
-------------------------------
-
-The most recent version of this driver will hopefully always be available at
- http://www.zabbo.net/maestro3/
-
-I will try and maintain the most recent stable version of the driver
-in both the stable and development kernel lines.
-
-Historically I've sucked pretty hard at actually doing that, however.
-
-ESS Maestro3 Chip Family
------------------------
-
-The 'Maestro3' is much like the Maestro2 chip. The noted improvement
-is the removal of the silicon in the '2' that did PCM mixing. All that
-work is now done through a custom DSP called the ASSP, the Asynchronus
-Specific Signal Processor.
-
-The 'Allegro' is a baby version of the Maestro3. I'm not entirely clear
-on the extent of the differences, but the driver supports them both :)
-
-The 'Allegro' shows up as PCI ID 0x1988 and the Maestro3 as 0x1998,
-both under ESS's vendor ID of 0x125D. The Maestro3 can also show up as
-0x199a when hardware strapping is used.
-
-The chip can also act as a multi function device. The modem IDs follow
-the audio multimedia device IDs. (so the modem part of an Allegro shows
-up as 0x1989)
-
-Driver OSS Behavior
---------------------
-
-This OSS driver exports /dev/mixer and /dev/dsp to applications, which
-mostly adhere to the OSS spec. This driver doesn't register itself
-with /dev/sndstat, so don't expect information to appear there.
-
-The /dev/dsp device exported behaves as expected. Playback is
-supported in all the various lovely formats. 8/16bit stereo/mono from
-8khz to 48khz, with both read()/write(), and mmap().
-
-/dev/mixer is an interface to the AC'97 codec on the Maestro3. It is
-worth noting that there are a variety of AC'97s that can be wired to
-the Maestro3. Which is used is entirely up to the hardware implementor.
-This should only be visible to the user by the presence, or lack, of
-'Bass' and 'Treble' sliders in the mixer. Not all AC'97s have them.
-The Allegro has an onchip AC'97.
-
-The driver doesn't support MIDI or FM playback at the moment.
-
-Compiling and Installing
-------------------------
-
-With the drivers inclusion into the kernel, compiling and installing
-is the same as most OSS/Lite modular sound drivers. Compilation
-of the driver is enabled through the CONFIG_SOUND_MAESTRO3 variable
-in the config system.
-
-It may be modular or statically linked. If it is modular it should be
-installed with the rest of the modules for the kernel on the system.
-Typically this will be in /lib/modules/ somewhere. 'alias sound-slot-0
-maestro3' should also be added to your module configs (typically
-/etc/modprobe.conf) if you're using modular OSS/Lite sound and want to
-default to using a maestro3 chip.
-
-There are very few options to the driver. One is 'debug' which will
-tell the driver to print minimal debugging information as it runs. This
-can be collected with 'dmesg' or through the klogd daemon.
-
-One is 'external_amp', which tells the driver to attempt to enable
-an external amplifier. This defaults to '1', you can tell the driver
-not to bother enabling such an amplifier by setting it to '0'.
-
-And the last is 'gpio_pin', which tells the driver which GPIO pin number
-the external amp uses (0-15), The Allegro uses 8 by default, all others 1.
-If everything loads correctly and seems to be working but you get no sound,
-try tweaking this value.
-
-Systems known to need a different value
- Panasonic ToughBook CF-72: gpio_pin=13
-
-Power Management
-----------------
-
-This driver has a minimal understanding of PCI Power Management. It will
-try and power down the chip when the system is suspended, and power
-it up with it is resumed. It will also try and power down the chip
-when the machine is shut down.

-Linux 2.4 Sound Changes
-2000-September-25
-Christoph Hellwig, <hch@infradead.org>
-
-
-
-=== isapnp support
-
-The Linux 2.4 Kernel does have reliable in-kernel isapnp support.
-Some drivers (sb.o, ad1816.o awe_wave.o) do now support automatically
-detecting and configuring isapnp devices.
-If you have a not yet supported isapnp soundcard, mail me the content
-of '/proc/isapnp' on your system and some information about your card
-and its driver(s) so I can try to get isapnp working for it.
-
-
-
-=== soundcard resources on kernel commandline
-
-Before Linux 2.4 you had to specify the resources for sounddrivers
-statically linked into the kernel at compile time
-(in make config/menuconfig/xconfig). In Linux 2.4 the resources are
-now specified at the boot-time kernel commandline (e.g. the lilo
-'append=' line or everything that's after the kernel name in grub).
-Read the Configure.help entry for your card for the parameters.
-
-
-=== softoss is gone
-
-In Linux 2.4 the softoss in-kernel software synthesizer is no more aviable.
-Use a user space software synthesizer like timidity instead.
-
-
-
-=== /dev/sndstat and /proc/sound are gone
-
-In older Linux versions those files exported some information about the
-OSS/Free configuration to userspace. In Linux 2.3 they were removed because
-they did not support the growing number of pci soundcards and there were
-some general problems with this interface.

-OPL3-SA1 sound driver (opl3sa.o)
-
----
-Note: This howto only describes how to setup the OPL3-SA1 chip; this info
-does not apply to the SA2, SA3, or SA4.
----
-
-The Yamaha OPL3-SA1 sound chip is usually found built into motherboards, and
-it's a decent little chip offering a WSS mode, a SB Pro emulation mode, MPU401
-and OPL3 FM Synth capabilities.
-
-You can enable inclusion of the driver via CONFIG_SOUND_OPL3SA1=m, or
-CONFIG_SOUND_OPL3SA1=y through 'make config/xconfig/menuconfig'.
-
-You'll need to know all of the relevant info (irq, dma, and io port) for the
-chip's WSS mode, since that is the mode the kernel sound driver uses, and of
-course you'll also need to know about where the MPU401 and OPL3 ports and
-IRQs are if you want to use those.
-
-Here's the skinny on how to load it as a module:
-
- modprobe opl3sa io=0x530 irq=11 dma=0 dma2=1 mpu_io=0x330 mpu_irq=5
-
-Module options in detail:
-
- io: This is the WSS's port base.
- irq: This is the WSS's IRQ.
- dma: This is the WSS's DMA line. In my BIOS setup screen this was
- listed as "WSS Play DMA"
- dma2: This is the WSS's secondary DMA line. My BIOS calls it the
- "WSS capture DMA"
-
- mpu_io: This is the MPU401's port base.
- mpu_irq: This is the MPU401's IRQ.
-
-If you'd like to use the OPL3 FM Synthesizer, make sure you enable
-CONFIG_SOUND_YM3812 (in 'make config'). That'll build the opl3.o module.
-
-Then a simple 'insmod opl3 io=0x388', and you now have FM Synth.
-
-You can also use the SoftOSS software synthesizer instead of the builtin OPL3.
-Here's how:
-
-Say 'y' or 'm' to "SoftOSS software wave table engine" in make config.
-
-If you said yes, the software synth is available once you boot your new
-kernel.
-
-If you chose to build it as a module, just insmod the resulting softoss2.o

-================================================================
- AWE32 Sound Driver for Linux / FreeBSD
- version 0.4.3; Nov. 1, 1998
-
- Takashi Iwai <iwai@ww.uni-erlangen.de>
-================================================================
-
-* GENERAL NOTES
-
-This is a sound driver extension for SoundBlaster AWE32 and other
-compatible cards (AWE32-PnP, SB32, SB32-PnP, AWE64 & etc) to enable
-the wave synth operations. The driver is provided for Linux 1.2.x
-and 2.[012].x kernels, as well as FreeBSD, on Intel x86 and DEC
-Alpha systems.
-
-This driver was written by Takashi Iwai <iwai@ww.uni-erlangen.de>,
-and provided "as is". The original source (awedrv-0.4.3.tar.gz) and
-binary packages are available on the following URL:
- http://bahamut.mm.t.u-tokyo.ac.jp/~iwai/awedrv/
-Note that since the author is apart from this web site, the update is
-not frequent now.
-
-
-* NOTE TO LINUX USERS
-
-To enable this driver on linux-2.[01].x kernels, you need turn on
-"AWE32 synth" options in sound menu when configure your linux kernel
-and modules. The precise installation procedure is described in the
-AWE64-Mini-HOWTO and linux-kernel/Documetation/sound/AWE32.
-
-If you're using PnP cards, the card must be initialized before loading
-the sound driver. There're several options to do this:
- - Initialize the card via ISA PnP tools, and load the sound module.
- - Initialize the card on DOS, and load linux by loadlin.exe
- - Use PnP kernel driver (for Linux-2.x.x)
-The detailed instruction for the solution using isapnp tools is found
-in many documents like above. A brief instruction is also included in
-the installation document of this package.
-For PnP driver project, please refer to the following URL:
- http://www-jcr.lmh.ox.ac.uk/~pnp/
-
-
-* USING THE DRIVER
-
-The awedrv has several different playing modes to realize easy channel
-allocation for MIDI songs. To hear the exact sound quality, you need
-to obtain the extended sequencer program, drvmidi or playmidi-2.5.
-
-For playing MIDI files, you *MUST* load the soundfont file on the
-driver previously by sfxload utility. Otherwise you'll here no sounds
-at all! All the utilities and driver source packages are found in the
-above URL. The sfxload program is included in the package
-awesfx-0.4.3.tgz. Binary packages are available there, too. See the
-instruction in each package for installation.
-
-Loading a soundfont file is very simple. Just execute the command
-
- % sfxload synthgm.sbk
-
-Then, sfxload transfers the file "synthgm.sbk" to the driver.
-Both SF1 and SF2 formats are accepted.
-
-Now you can hear midi musics by a midi player.
-
- % drvmidi foo.mid
-
-If you run MIDI player after MOD player, you need to load soundfont
-files again, since MOD player programs clear the previous loaded
-samples by their own data.
-
-If you have only 512kb on the sound card, I recommend to use dynamic
-sample loading via -L option of drvmidi. 2MB GM/GS soundfont file is
-available in most midi files.
-
- % sfxload synthgm
- % drvmidi -L 2mbgmgs foo.mid
-
-This makes a big difference (believe me)! For more details, please
-refer to the FAQ list which is available on the URL above.
-
-The current chorus, reverb and equalizer status can be changed by
-aweset utility program (included in awesfx package). Note that
-some awedrv-native programs (like drvmidi and xmp) will change the
-current settings by themselves. The aweset program is effective
-only for other programs like playmidi.
-
-Enjoy.
-
-
-* COMPILE FLAGS
-
-Compile conditions are defined in awe_config.h.
-
-[Compatibility Conditions]
-The following flags are defined automatically when using installation
-shell script.
-
-- AWE_MODULE_SUPPORT
- indicates your Linux kernel supports module for each sound card
- (in recent 2.1 or 2.2 kernels and unofficial patched 2.0 kernels
- as distributed in the RH5.0 package).
- This flag is automatically set when you're using 2.1.x kernels.
- You can pass the base address and memory size via the following
- module options,
- io = base I/O port address (eg. 0x620)
- memsize = DRAM size in kilobytes (eg. 512)
- As default, AWE driver probes these values automatically.
-
-
-[Hardware Conditions]
-You DON'T have to define the following two values.
-Define them only when the driver couldn't detect the card properly.
-
-- AWE_DEFAULT_BASE_ADDR (default: not defined)
- specifies the base port address of your AWE32 card.
- 0 means to autodetect the address.
-
-- AWE_DEFAULT_MEM_SIZE (default: not defined)
- specifies the memory size of your AWE32 card in kilobytes.
- -1 means to autodetect its size.
-
-
-[Sample Table Size]
-From ver.0.4.0, sample tables are allocated dynamically (except
-Linux-1.2.x system), so you need NOT to touch these parameters.
-Linux-1.2.x users may need to increase these values to appropriate size
-if the sound card is equipped with more DRAM.
-
-- AWE_MAX_SF_LISTS, AWE_MAX_SAMPLES, AWE_MAX_INFOS
-
-
-[Other Conditions]
-
-- AWE_ALWAYS_INIT_FM (default: not defined)
- indicates the AWE driver always initialize FM passthrough even
- without DRAM on board. Emu8000 chip has a restriction for playing
- samples on DRAM that at least two channels must be occupied as
- passthrough channels.
-
-- AWE_DEBUG_ON (default: defined)
- turns on debugging messages if defined.
-
-- AWE_HAS_GUS_COMPATIBILITY (default: defined)
- Enables GUS compatibility mode if defined, reading GUS patches and
- GUS control commands. Define this option to use GMOD or other
- GUS module players.
-
-- CONFIG_AWE32_MIDIEMU (default: defined)
- Adds a MIDI emulation device by Emu8000 wavetable. The emulation
- device can be accessed as an external MIDI, and sends the MIDI
- control codes directly. XG and GS sysex/NRPN are accepted.
- No MIDI input is supported.
-
-- CONFIG_AWE32_MIXER (default: not defined)
- Adds a mixer device for AWE32 bass/treble equalizer control.
- You can access this device using /dev/mixer?? (usually mixer01).
-
-- AWE_USE_NEW_VOLUME_CALC (default: defined)
- Use the new method to calculate the volume change as compatible
- with DOS/Win drivers. This option can be toggled via aweset
- program, or drvmidi player.
-
-- AWE_CHECK_VTARGET (default: defined)
- Check the current volume target value when searching for an
- empty channel to allocate a new voice. This is experimentally
- implemented in this version. (probably, this option doesn't
- affect the sound quality severely...)
-
-- AWE_ALLOW_SAMPLE_SHARING (default: defined)
- Allow sample sharing for differently loaded patches.
- This function is available only together with awesfx-0.4.3p3.
- Note that this is still an experimental option.
-
-- DEF_FM_CHORUS_DEPTH (default: 0x10)
- The default strength to be sent to the chorus effect engine.
- From 0 to 0xff. Larger numbers may often cause weird sounds.
-
-- DEF_FM_REVERB_DEPTH (default: 0x10)
- The default strength to be sent to the reverb effect engine.
- From 0 to 0xff. Larger numbers may often cause weird sounds.
-
-

- An OSS/Free Driver for WaveFront soundcards
- (Turtle Beach Maui, Tropez, Tropez Plus)
-
- Paul Barton-Davis, July 1998
-
- VERSION 0.2.5
-
-Driver Status
--------------
-
-Requires: Kernel 2.1.106 or later (the driver is included with kernels
-2.1.109 and above)
-
-As of 7/22/1998, this driver is currently in *BETA* state. This means
-that it compiles and runs, and that I use it on my system (Linux
-2.1.106) with some reasonably demanding applications and uses. I
-believe the code is approaching an initial "finished" state that
-provides bug-free support for the Tropez Plus.
-
-Please note that to date, the driver has ONLY been tested on a Tropez
-Plus. I would very much like to hear (and help out) people with Tropez
-and Maui cards, since I think the driver can support those cards as
-well.
-
-Finally, the driver has not been tested (or even compiled) as a static
-(non-modular) part of the kernel. Alan Cox's good work in modularizing
-OSS/Free for Linux makes this rather unnecessary.
-
-Some Questions
---------------
-
-**********************************************************************
-0) What does this driver do that the maui driver did not ?
-**********************************************************************
-
-* can fully initialize a WaveFront card from cold boot - no DOS
- utilities needed
-* working patch/sample/program loading and unloading (the maui
- driver didn't document how to make this work, and assumed
- user-level preparation of the patch data for writing
- to the board. ick.)
-* full user-level access to all WaveFront commands
-* for the Tropez Plus, (primitive) control of the YSS225 FX processor
-* Virtual MIDI mode supported - 2 MIDI devices accessible via the
- WaveFront's MPU401/UART emulation. One
- accesses the WaveFront synth, the other accesses the
- external MIDI connector. Full MIDI read/write semantics
- for both devices.
-* OSS-compliant /dev/sequencer interface for the WaveFront synth,
- including native and GUS-format patch downloading.
-* semi-intelligent patch management (prototypical at this point)
-
-**********************************************************************
-1) What to do about MIDI interfaces ?
-**********************************************************************
-
-The Tropez Plus (and perhaps other WF cards) can in theory support up
-to 2 physical MIDI interfaces. One of these is connected to the
-ICS2115 chip (the WaveFront synth itself) and is controlled by
-MPU/UART-401 emulation code running as part of the WaveFront OS. The
-other is controlled by the CS4232 chip present on the board. However,
-physical access to the CS4232 connector is difficult, and it is
-unlikely (though not impossible) that you will want to use it.
-
-An older version of this driver introduced an additional kernel config
-variable which controlled whether or not the CS4232 MIDI interface was
-configured. Because of Alan Cox's work on modularizing the sound
-drivers, and now backporting them to 2.0.34 kernels, there seems to be
-little reason to support "static" configuration variables, and so this
-has been abandoned in favor of *only* module parameters. Specifying
-"mpuio" and "mpuirq" for the cs4232 parameter will result in the
-CS4232 MIDI interface being configured; leaving them unspecified will
-leave it unconfigured (and thus unusable).
-
-BTW, I have heard from one Tropez+ user that the CS4232 interface is
-more reliable than the ICS2115 one. I have had no problems with the
-latter, and I don't have the right cable to test the former one
-out. Reports welcome.
-
-**********************************************************************
-2) Why does line XXX of the code look like this .... ?
-**********************************************************************
-
-Either because it's not finished yet, or because you're a better coder
-than I am, or because you don't understand some aspect of how the card
-or the code works.
-
-I absolutely welcome comments, criticisms and suggestions about the
-design and implementation of the driver.
-
-**********************************************************************
-3) What files are included ?
-**********************************************************************
-
- drivers/sound/README.wavefront -- this file
-
- drivers/sound/wavefront.patch -- patches for the 2.1.106 sound drivers
- needed to make the rest of this work
- DO NOT USE IF YOU'VE APPLIED THEM
- BEFORE, OR HAVE 2.1.109 OR ABOVE
-
- drivers/sound/wavfront.c -- the driver

-
-**********************************************************************
-4) How do I compile/install/use it ?
-**********************************************************************
-
-PART ONE: install the source code into your sound driver directory
-
- cd <top-of-your-2.1.106-code-base-e.g.-/usr/src/linux>
- tar -zxvf <where-you-put/wavefront.tar.gz>
-
-PART TWO: apply the patches
-
- DO THIS ONLY IF YOU HAVE A KERNEL VERSION BELOW 2.1.109
- AND HAVE NOT ALREADY INSTALLED THE PATCH(ES).
-
- cd drivers/sound
- patch < wavefront.patch
-
-PART THREE: configure your kernel
-
- cd <top of your kernel tree>
- make xconfig (or whichever config option you use)
-
- - choose YES for Sound Support
- - choose MODULE (M) for OSS Sound Modules
- - choose MODULE(M) to YM3812/OPL3 support
- - choose MODULE(M) for WaveFront support
- - choose MODULE(M) for CS4232 support
-
- - choose "N" for everything else (unless you have other
- soundcards you want support for)
-
-
- make boot
- .
- .
- .
- <whatever you normally do for a kernel install>
- make modules
- .
- .
- .
- make modules_install
-
-Here's my autoconf.h SOUND section:

-
-************************************************************
-6) How do I configure my card ?
-************************************************************
-
-You need to edit /etc/modprobe.conf. Here's mine (edited to show the
-relevant details):
-
- # Sound system
- alias char-major-14-* wavefront
- alias synth0 wavefront
- alias mixer0 cs4232
- alias audio0 cs4232
- install wavefront /sbin/modprobe cs4232 && /sbin/modprobe -i wavefront && /sbin/modprobe opl3
- options wavefront io=0x200 irq=9
- options cs4232 synthirq=9 synthio=0x200 io=0x530 irq=5 dma=1 dma2=0
- options opl3 io=0x388
-
-Things to note:
-
- the wavefront options "io" and "irq" ***MUST*** match the "synthio"
- and "synthirq" cs4232 options.
-
- you can do without the opl3 module if you don't
- want to use the OPL/[34] FM synth on the soundcard
-
- the opl3 io parameter is conventionally not adjustable.
- In theory, any not-in-use IO port address would work, but
- just use 0x388 and stick with the crowd.
-
-**********************************************************************
-7) What about firmware ?
-**********************************************************************
-
-Turtle Beach have not given me permission to distribute their firmware
-for the ICS2115. However, if you have a WaveFront card, then you
-almost certainly have the firmware, and if not, its freely available
-on their website, at:
-
- http://www.tbeach.com/tbs/downloads/scardsdown.htm#tropezplus
-
-The file is called WFOS2001.MOT (for the Tropez+).
-
-This driver, however, doesn't use the pure firmware as distributed,
-but instead relies on a somewhat processed form of it. You can
-generate this very easily. Following an idea from Andrew Veliath's
-Pinnacle driver, the following flex program will generate the
-processed version:
-
----- cut here -------------------------
-%option main
-%%
-^S[28].*\r$ printf ("%c%.*s", yyleng-1,yyleng-1,yytext);
-<<EOF>> { fputc ('\0', stdout); return; }
-\n {}
-. {}
----- cut here -------------------------
-
-To use it, put the above in file (say, ws.l) compile it like this:
-
- shell> flex -ows.c ws.l
- shell> cc -o ws ws.c
-
-and then use it like this:
-
- ws < my-copy-of-the-oswf.mot-file > /etc/sound/wavefront.os
-
-If you put it somewhere else, you'll always have to use the wf_ospath
-module parameter (see below) or alter the source code.
-
-**********************************************************************
-7) How do I get it working ?
-**********************************************************************
-
-Optionally, you can reboot with the "new" kernel (even though the only
-changes have really been made to a module).
-
-Then, as root do:
-
- modprobe wavefront
-
-You should get something like this in /var/log/messages:
-
- WaveFront: firmware 1.20 already loaded.
-
-or
-
- WaveFront: no response to firmware probe, assume raw.
-
-then:
-
- WaveFront: waiting for memory configuration ...
- WaveFront: hardware version 1.64
- WaveFront: available DRAM 8191k
- WaveFront: 332 samples used (266 real, 13 aliases, 53 multi), 180 empty
- WaveFront: 128 programs slots in use
- WaveFront: 256 patch slots filled, 142 in use
-
-The whole process takes about 16 seconds, the longest waits being
-after reporting the hardware version (during the firmware download),
-and after reporting program status (during patch status inquiry). Its
-shorter (about 10 secs) if the firmware is already loaded (i.e. only
-warm reboots since the last firmware load).
-
-The "available DRAM" line will vary depending on how much added RAM
-your card has. Mine has 8MB.
-
-To check basically functionality, use play(1) or splay(1) to send a
-.WAV or other audio file through the audio portion. Then use playmidi
-to play a General MIDI file. Try the "-D 0" to hear the
-difference between sending MIDI to the WaveFront and using the OPL/3,
-which is the default (I think ...). If you have an external synth(s)
-hooked to the soundcard, you can use "-e" to route to the
-external synth(s) (in theory, -D 1 should work as well, but I think
-there is a bug in playmidi which prevents this from doing what it
-should).
-
-**********************************************************************
-8) What are the module parameters ?
-**********************************************************************
-
-Its best to read wavefront.c for this, but here is a summary:
-
-integers:
- wf_raw - if set, ignore apparent presence of firmware
- loaded onto the ICS2115, reset the whole
- board, and initialize it from scratch. (default = 0)
-
- fx_raw - if set, always initialize the YSS225 processor
- on the Tropez plus. (default = 1)
-
- < The next 4 are basically for kernel hackers to allow
- tweaking the driver for testing purposes. >
-
- wait_usecs - loop timer used when waiting for
- status conditions on the board.
- The default is 150.
-
- debug_default - debugging flags. See sound/wavefront.h
- for WF_DEBUG_* values. Default is zero.
- Setting this allows you to debug the
- driver during module installation.
-strings:
- ospath - path to get to the pre-processed OS firmware.
- (default: /etc/sound/wavefront.os)
-
-**********************************************************************
-9) Who should I contact if I have problems?
-**********************************************************************

-Just me: Paul Barton-Davis <pbd@op.net>

+++ /dev/null
-/proc/sound, /dev/sndstat
--------------------------
-
-/proc/sound and /dev/sndstat is not supported by the
-driver. To find out whether the driver succeeded loading,
-check the kernel log (dmesg).
-
-
-ALaw/uLaw sample formats
-------------------------
-
-This driver does not support the ALaw/uLaw sample formats.
-ALaw is the default mode when opening a sound device
-using OSS/Free. The reason for the lack of support is
-that the hardware does not support these formats, and adding
-conversion routines to the kernel would lead to very ugly
-code in the presence of the mmap interface to the driver.
-And since xquake uses mmap, mmap is considered important :-)
-and no sane application uses ALaw/uLaw these days anyway.
-In short, playing a Sun .au file as follows:
-
-cat my_file.au > /dev/dsp
-
-does not work. Instead, you may use the play script from
-Chris Bagwell's sox-12.14 package (available from the URL
-below) to play many different audio file formats.
-The script automatically determines the audio format
-and does do audio conversions if necessary.
-http://home.sprynet.com/sprynet/cbagwell/projects.html
-
-
-Blocking vs. nonblocking IO
----------------------------
-
-Unlike OSS/Free this driver honours the O_NONBLOCK file flag
-not only during open, but also during read and write.
-This is an effort to make the sound driver interface more
-regular. Timidity has problems with this; a patch
-is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
-(Timidity patched will also run on OSS/Free).
-
-
-MIDI UART
----------
-
-The driver supports a simple MIDI UART interface, with
-no ioctl's supported.
-
-
-MIDI synthesizer
-----------------
-
-This soundcard does not have any hardware MIDI synthesizer;
-MIDI synthesis has to be done in software. To allow this
-the driver/soundcard supports two PCM (/dev/dsp) interfaces.
-The second one goes to the mixer "synth" setting and supports
-only a limited set of sampling rates (44100, 22050, 11025, 5512).
-By setting lineout to 1 on the driver command line
-(eg. insmod es1370 lineout=1) it is even possible on some
-cards to convert the LINEIN jack into a second LINEOUT jack, thus
-making it possible to output four independent audio channels!
-
-There is a freely available software package that allows
-MIDI file playback on this soundcard called Timidity.
-See http://www.cgs.fi/~tt/timidity/.

-Beta release of the rme96xx (driver for RME 96XX cards like the
-"Hammerfall" and the "Hammerfall light")
-
-Important: The driver module has to be installed on a freshly rebooted system,
-otherwise the driver might not be able to acquire its buffers.
-
-features:
-
- - OSS programming interface (i.e. runs with standard OSS soundsoftware)
- - OSS/Multichannel interface (OSS multichannel is done by just aquiring
- more than 2 channels). The driver does not use more than one device
- ( yet .. this feature may be implemented later )
- - more than one RME card supported
-
-The driver uses a specific multichannel interface, which I will document
-when the driver gets stable. (take a look at the defines in rme96xx.h,
-which adds blocked multichannel formats i.e instead of
-lrlrlrlr --> llllrrrr etc.
-
-Use the "rmectrl" programm to look at the status of the card ..
-or use xrmectrl, a GUI interface for the ctrl program.
-
-What you can do with the rmectrl program is to set the stereo device for
-OSS emulation (e.g. if you use SPDIF out).
-
-You do:
-
-./ctrl offset 24 24
-
-which makes the stereo device use channels 25 and 26.
-
-Guenter Geiger <geiger@epy.co.at>
-
-copy the first part of the attached source code into rmectrl.c
-and the second part into xrmectrl (or get the program from
-http://gige.xdv.org/pages/soft/pages/rme)
-
-to compile: gcc -o rmectrl rmectrl.c

-Recording
----------
-
-Recording does not work on the author's card, but there
-is at least one report of it working on later silicon.
-The chip behaves differently than described in the data sheet,
-likely due to a chip bug. Working around this would require
-the help of ESS (for example by publishing an errata sheet),
-but ESS has not done so far.
-
-Also, the chip only supports 24 bit addresses for recording,
-which means it cannot work on some Alpha mainboards.
-
-
-/proc/sound, /dev/sndstat
--------------------------
-
-/proc/sound and /dev/sndstat is not supported by the
-driver. To find out whether the driver succeeded loading,
-check the kernel log (dmesg).
-
-
-ALaw/uLaw sample formats
-------------------------
-
-This driver does not support the ALaw/uLaw sample formats.
-ALaw is the default mode when opening a sound device
-using OSS/Free. The reason for the lack of support is
-that the hardware does not support these formats, and adding
-conversion routines to the kernel would lead to very ugly
-code in the presence of the mmap interface to the driver.
-And since xquake uses mmap, mmap is considered important :-)
-and no sane application uses ALaw/uLaw these days anyway.
-In short, playing a Sun .au file as follows:
-
-cat my_file.au > /dev/dsp
-
-does not work. Instead, you may use the play script from
-Chris Bagwell's sox-12.14 package (or later, available from the URL
-below) to play many different audio file formats.
-The script automatically determines the audio format
-and does do audio conversions if necessary.
-http://home.sprynet.com/sprynet/cbagwell/projects.html
-
-
-Blocking vs. nonblocking IO
----------------------------
-
-Unlike OSS/Free this driver honours the O_NONBLOCK file flag
-not only during open, but also during read and write.
-This is an effort to make the sound driver interface more
-regular. Timidity has problems with this; a patch
-is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
-(Timidity patched will also run on OSS/Free).
-
-
-MIDI UART
----------
-
-The driver supports a simple MIDI UART interface, with
-no ioctl's supported.
-
-
-MIDI synthesizer
-----------------
-
-The card has an OPL compatible FM synthesizer.

-MIDI UART
----------
-
-The driver supports a simple MIDI UART interface, with

-
-
-MIDI synthesizer
-----------------
-
-The card both has an OPL compatible FM synthesizer as well as
-a wavetable synthesizer.
-
-I haven't managed so far to get the OPL synth running.
-
-Using the wavetable synthesizer requires allocating
-1-4MB of physically contiguous memory, which isn't possible
-currently on Linux without ugly hacks like the bigphysarea
-patch. Therefore, the driver doesn't support wavetable
-synthesis.
-
-
-No support from S3
-------------------
-
-I do not get any support from S3. Therefore, the driver
-still has many problems. For example, although the manual
-states that the chip should be able to access the sample
-buffer anywhere in 32bit address space, I haven't managed to
-get it working with buffers above 16M. Therefore, the card
-has the same disadvantages as ISA soundcards.
-
-Given that the card is also very noisy, and if you haven't
-already bought it, you should strongly opt for one of the
-comparatively priced Ensoniq products.

- Because most/all of the sample data we pass in via pointers has

- So, we need a way of specifying which channel to use (the WaveFront

- wavefront_sample:

- 0 no channel selection (use channel 1, sample is MONO)
- 1 use first channel, and skip one
- 2 use second channel, and skip one
- 3 use third channel, and skip two
- 4 use fourth channel, skip three
- 5 use fifth channel, skip four
- 6 use six channel, skip five
-
-
- This can handle up to 4 channels, and anyone downloading >4 channels
- of sample data just to select one of them needs to find some tools
- like sox ...
-
- NOTE: values 0, 1 and 2 correspond to WF_CH_* above. This is

- * ALI ali5455 and friends ICH driver for Linux
- * LEI HU <Lei_Hu@ali.com.tw>
- *
- * Built from:
- * drivers/sound/i810_audio
- *
- * The ALi 5455 is similar but not quite identical to the Intel ICH
- * series of controllers. Its easier to keep the driver separated from
- * the i810 driver.

- * ALi 5455 theory of operation
- *
- * The chipset provides three DMA channels that talk to an AC97
- * CODEC (AC97 is a digital/analog mixer standard). At its simplest
- * you get 48Khz audio with basic volume and mixer controls. At the
- * best you get rate adaption in the codec. We set the card up so
- * that we never take completion interrupts but instead keep the card
- * chasing its tail around a ring buffer. This is needed for mmap
- * mode audio and happens to work rather well for non-mmap modes too.
- *
- * The board has one output channel for PCM audio (supported) and
- * a stereo line in and mono microphone input. Again these are normally
- * locked to 48Khz only. Right now recording is not finished.
- *
- * There is no midi support, no synth support. Use timidity. To get
- * esd working you need to use esd -r 48000 as it won't probe 48KHz
- * by default. mpg123 can't handle 48Khz only audio so use xmms.
- *
- * If you need to force a specific rate set the clocking= option
- *

- *
- * Special thanks to David C. Niemi, Jan Pfeifer
- *
- *
- * Module command line parameters:
- * none so far
- *
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * The card has both an FM and a Wavetable synth, but I have to figure
- * out first how to drive them...
- *
- * Revision history
- * 06.05.98 0.1 Initial release
- * 10.05.98 0.2 Fixed many bugs, esp. ADC rate calculation
- * First stab at a simple midi interface (no bells&whistles)
- * 13.05.98 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
- * set_dac_rate in the FMODE_WRITE case in cm_open
- * Fix hwptr out of bounds (now mpg123 works)
- * 14.05.98 0.4 Don't allow excessive interrupt rates
- * 08.06.98 0.5 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.98 0.6 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.98 0.7 Fix realplayer problems - dac.count issues
- * 10.12.98 0.8 Fix drain_dac trying to wait on not yet initialized DMA
- * 16.12.98 0.9 Fix a few f_file & FMODE_ bugs
- * 06.01.99 0.10 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.99 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.99 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 18.08.99 1.5 Only deallocate DMA buffer when unloading.
- * 02.09.99 1.6 Enable SPDIF LOOP
- * Change the mixer read back
- * 21.09.99 2.33 Use RCS version as driver version.
- * Add support for modem, S/PDIF loop and 4 channels.
- * (8738 only)
- * Fix bug cause x11amp cannot play.
- *
- * Fixes:
- * Arnaldo Carvalho de Melo <acme@conectiva.com.br>
- * 18/05/2001 - .bss nitpicks, fix a bug in set_dac_channels where it
- * was calling prog_dmabuf with s->lock held, call missing
- * unlock_kernel in cm_midi_release
- * 08/10/2001 - use set_current_state in some more places
- *
- * Carlos Eduardo Gorges <carlos@techlinux.com.br>
- * Fri May 25 2001
- * - SMP support ( spin[un]lock* revision )
- * - speaker mixer support
- * Mon Aug 13 2001
- * - optimizations and cleanups
- *
- * 03/01/2003 - open_mode fixes from Georg Acher <acher@in.tum.de>
- * Simon Braunschmidt <brasimon@web.de>
- * Sat Jan 31 2004
- * - provide support for opl3 FM by releasing IO range after initialization
- *
- * ChenLi Tien <cltien@cmedia.com.tw>
- * Mar 9 2004
- * - Fix S/PDIF out if spdif_loop enabled
- * - Load opl3 driver if enabled (fmio in proper range)
- * - Load mpu401 if enabled (mpuio in proper range)
- * Apr 5 2004
- * - Fix DUAL_DAC dma synchronization bug
- * - Check exist FM/MPU401 I/O before activate.
- * - Add AFTM_S16_BE format support, so MPlayer/Xine can play AC3/mutlichannel
- * on Mac
- * - Change to support kernel 2.6 so only small patch needed
- * - All parameters default to 0
- * - Add spdif_out to send PCM through S/PDIF out jack
- * - Add hw_copy to get 4-spaker output for general PCM/analog output
- *
- * Stefan Thater <stefan.thaeter@gmx.de>
- * Apr 5 2004
- * - Fix mute single channel for CD/Line-in/AUX-in

-*
-* Modification History
-* 08/20/00 trw - silence and no stopping DAC until release
-* 08/23/00 trw - added CS_DBG statements, fix interrupt hang issue on DAC stop.
-* 09/18/00 trw - added 16bit only record with conversion
-* 09/24/00 trw - added Enhanced Full duplex (separate simultaneous
-* capture/playback rates)
-* 10/03/00 trw - fixed mmap (fixed GRECORD and the XMMS mmap test plugin
-* libOSSm.so)
-* 10/11/00 trw - modified for 2.4.0-test9 kernel enhancements (NR_MAP removal)
-* 11/03/00 trw - fixed interrupt loss/stutter, added debug.
-* 11/10/00 bkz - added __devinit to cs4281_hw_init()
-* 11/10/00 trw - fixed SMP and capture spinlock hang.
-* 12/04/00 trw - cleaned up CSDEBUG flags and added "defaultorder" moduleparm.
-* 12/05/00 trw - fixed polling (myth2), and added underrun swptr fix.
-* 12/08/00 trw - added PM support.
-* 12/14/00 trw - added wrapper code, builds under 2.4.0, 2.2.17-20, 2.2.17-8
-* (RH/Dell base), 2.2.18, 2.2.12. cleaned up code mods by ident.
-* 12/19/00 trw - added PM support for 2.2 base (apm_callback). other PM cleanup.
-* 12/21/00 trw - added fractional "defaultorder" inputs. if >100 then use
-* defaultorder-100 as power of 2 for the buffer size. example:
-* 106 = 2^(106-100) = 2^6 = 64 bytes for the buffer size.

- * Special thanks to David C. Niemi
- *
- *
- * Module command line parameters:
- * lineout if 1 the LINE jack is used as an output instead of an input.
- * LINE then contains the unmixed dsp output. This can be used
- * to make the card a four channel one: use dsp to output two
- * channels to LINE and dac to output the other two channels to
- * SPKR. Set the mixer to only output synth to SPKR.
- * micbias sets the +5V bias to the mic if using an electretmic.
- *
- *
- * Note: sync mode is not yet supported (i.e. running dsp and dac from the same
- * clock source)
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/dsp1 additional DAC, like /dev/dsp, but output only,
- * only 5512, 11025, 22050 and 44100 samples/s,
- * outputs to mixer "SYNTH" setting
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
- * to be done in software. That is what /dev/dac is for. By now (Q2 1998)
- * there are several MIDI to PCM (WAV) packages, one of them is timidity.
- *
- * Revision history
- * 26.03.1998 0.1 Initial release
- * 31.03.1998 0.2 Fix bug in GETOSPACE
- * 04.04.1998 0.3 Make it work (again) under 2.0.33
- * Fix mixer write operation not returning the actual
- * settings
- * 05.04.1998 0.4 First attempt at using the new PCI stuff
- * 29.04.1998 0.5 Fix hang when ^C is pressed on amp
- * 07.05.1998 0.6 Don't double lock around stop_*() in *_release()
- * 10.05.1998 0.7 First stab at a simple midi interface (no bells&whistles)
- * 14.05.1998 0.8 Don't allow excessive interrupt rates
- * 08.06.1998 0.9 First release using Alan Cox' soundcore instead of
- * miscdevice
- * 05.07.1998 0.10 Fixed the driver to correctly maintin OSS style volume
- * settings (not sure if this should be standard)
- * Fixed many references: f_flags should be f_mode
- * -- Gerald Britton <gbritton@mit.edu>
- * 03.08.1998 0.11 Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * Fixed mixer table thanks to Hakan.Lennestal@lu.erisoft.se
- * On module startup, set DAC2 to 11kSPS instead of 5.5kSPS,
- * as it produces an annoying ssssh in the lower sampling rate
- * Do not include modversions.h
- * 22.08.1998 0.12 Mixer registers actually have 5 instead of 4 bits
- * pointed out by Itai Nahshon
- * 31.08.1998 0.13 Fix realplayer problems - dac.count issues
- * 08.10.1998 0.14 Joystick support fixed
- * -- Oliver Neukum <c188@org.chemie.uni-muenchen.de>
- * 10.12.1998 0.15 Fix drain_dac trying to wait on not yet initialized DMA
- * 16.12.1998 0.16 Don't wake up app until there are fragsize bytes to read/write
- * 06.01.1999 0.17 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.1999 0.18 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.1999 0.19 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 07.04.1999 0.20 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * Note: joystick address handling might still be wrong on archs
- * other than i386
- * 10.05.1999 0.21 Added support for an electret mic for SB PCI64
- * to the Linux kernel sound driver. This mod also straighten
- * out the question marks around the mic impedance setting
- * (micz). From Kim.Berts@fisub.mail.abb.com
- * 11.05.1999 0.22 Implemented the IMIX call to mute recording monitor.
- * Guenter Geiger <geiger@epy.co.at>
- * 15.06.1999 0.23 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.24 Add pci_set_master
- * 02.08.1999 0.25 Added workaround for the "phantom write" bug first
- * documented by Dave Sharpless from Anchor Games
- * 03.08.1999 0.26 adapt to Linus' new __setup/__initcall
- * added kernel command line option "es1370=joystick[,lineout[,micbias]]"
- * removed CONFIG_SOUND_ES1370_JOYPORT_BOOT kludge
- * 12.08.1999 0.27 module_init/__setup fixes
- * 19.08.1999 0.28 SOUND_MIXER_IMIX fixes, reported by Gianluca <gialluca@mail.tiscalinet.it>
- * 31.08.1999 0.29 add spin_lock_init
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.30 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 28.10.1999 0.31 More waitqueue races fixed
- * 08.01.2000 0.32 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * 07.02.2000 0.33 Use pci_alloc_consistent and pci_register_driver
- * 21.11.2000 0.34 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.35 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 07.01.2001 0.36 Timeout change in wrcodec as requested by Frank Klemm <pfk@fuchs.offl.uni-jena.de>
- * 31.01.2001 0.37 Register/Unregister gameport
- * Fix SETTRIGGER non OSS API conformity
- * 03.01.2003 0.38 open_mode fixes from Georg Acher <acher@in.tum.de>
- *
- * some important things missing in Ensoniq documentation:
- *
- * Experimental PCLKDIV results: play the same waveforms on both DAC1 and DAC2
- * and vary PCLKDIV to obtain zero beat.
- * 5512sps: 254
- * 44100sps: 30
- * seems to be fs = 1411200/(PCLKDIV+2)
- *
- * should find out when curr_sample_ct is cleared and
- * where exactly the CCB fetches data
- *
- * The card uses a 22.5792 MHz crystal.
- * The LINEIN jack may be converted to an AOUT jack by
- * setting pin 47 (XCTL0) of the ES1370 to high.
- * Pin 48 (XCTL1) of the ES1370 sets the +5V bias for an electretmic
- *

- * Module command line parameters:
- * none so far
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * Revision history
- * 10.11.1998 0.1 Initial release (without any hardware)
- * 22.03.1999 0.2 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 07.04.1999 0.3 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * 15.06.1999 0.4 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.5 Add pci_set_master
- * 12.08.1999 0.6 Fix MIDI UART crashing the driver
- * Changed mixer semantics from OSS documented
- * behaviour to OSS "code behaviour".
- * Recording might actually work now.
- * The real DDMA controller address register is at PCI config
- * 0x60, while the register at 0x18 is used as a placeholder
- * register for BIOS address allocation. This register
- * is supposed to be copied into 0x60, according
- * to the Solo1 datasheet. When I do that, I can access
- * the DDMA registers except the mask bit, which
- * is stuck at 1. When I copy the contents of 0x18 +0x10
- * to the DDMA base register, everything seems to work.
- * The fun part is that the Windows Solo1 driver doesn't
- * seem to do these tricks.
- * Bugs remaining: plops and clicks when starting/stopping playback
- * 31.08.1999 0.7 add spin_lock_init
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.8 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 07.10.1999 0.9 Fix initialization; complain if sequencer writes time out
- * Revised resource grabbing for the FM synthesizer
- * 28.10.1999 0.10 More waitqueue races fixed
- * 09.12.1999 0.11 Work around stupid Alpha port issue (virt_to_bus(kmalloc(GFP_DMA)) > 16M)
- * Disabling recording on Alpha
- * 12.01.2000 0.12 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * Integrated (aka redid 8-)) APM support patch by Zach Brown
- * 07.02.2000 0.13 Use pci_alloc_consistent and pci_register_driver
- * 19.02.2000 0.14 Use pci_dma_supported to determine if recording should be disabled
- * 13.03.2000 0.15 Reintroduce initialization of a couple of PCI config space registers
- * 21.11.2000 0.16 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.17 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 31.01.2001 0.18 Register/Unregister gameport, original patch from
- * Nathaniel Daw <daw@cs.cmu.edu>
- * Fix SETTRIGGER non OSS API conformity
- * 10.03.2001 provide abs function, prevent picking up a bogus kernel macro
- * for abs. Bug report by Andrew Morton <andrewm@uow.edu.au>
- * 15.05.2001 pci_enable_device moved, return values in probe cleaned
- * up. Marcus Meissner <mm@caldera.de>
- * 22.05.2001 0.19 more cleanups, changed PM to PCI 2.4 style, got rid
- * of global list of devices, using pci device data.
- * Marcus Meissner <mm@caldera.de>
- * 03.01.2003 0.20 open_mode fixes from Georg Acher <acher@in.tum.de>

- This is a sound driver for ASP's and Lasi's Harmony sound chip
- and is unlikely to be used for anything other than on a HP PA-RISC.
-
- Harmony is found in HP 712s, 715/new and many other GSC based machines.
- On older 715 machines you'll find the technically identical chip
- called 'Vivace'. Both Harmony and Vicace are supported by this driver.

- *
- * Based heavily on SonicVibes.c:
- * Copyright (C) 1998-1999 Thomas Sailer (sailer@ife.ee.ethz.ch)
- *
- * Heavily modified by Zach Brown <zab@zabbo.net> based on lunch
- * with ESS engineers. Many thanks to Howard Kim for providing
- * contacts and hardware. Honorable mention goes to Eric
- * Brombaugh for all sorts of things. Best regards to the
- * proprietors of Hack Central for fine lodging.
- *
- * Supported devices:
- * /dev/dsp0-3 standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- *
- * Hardware Description
- *
- * A working Maestro setup contains the Maestro chip wired to a
- * codec or 2. In the Maestro we have the APUs, the ASSP, and the
- * Wavecache. The APUs can be though of as virtual audio routing
- * channels. They can take data from a number of sources and perform
- * basic encodings of the data. The wavecache is a storehouse for
- * PCM data. Typically it deals with PCI and interracts with the
- * APUs. The ASSP is a wacky DSP like device that ESS is loth
- * to release docs on. Thankfully it isn't required on the Maestro
- * until you start doing insane things like FM emulation and surround
- * encoding. The codecs are almost always AC-97 compliant codecs,
- * but it appears that early Maestros may have had PT101 (an ESS
- * part?) wired to them. The only real difference in the Maestro
- * families is external goop like docking capability, memory for
- * the ASSP, and initialization differences.
- *
- * Driver Operation
- *
- * We only drive the APU/Wavecache as typical DACs and drive the
- * mixers in the codecs. There are 64 APUs. We assign 6 to each
- * /dev/dsp? device. 2 channels for output, and 4 channels for
- * input.
- *
- * Each APU can do a number of things, but we only really use
- * 3 basic functions. For playback we use them to convert PCM
- * data fetched over PCI by the wavecahche into analog data that
- * is handed to the codec. One APU for mono, and a pair for stereo.
- * When in stereo, the combination of smarts in the APU and Wavecache
- * decide which wavecache gets the left or right channel.
- *
- * For record we still use the old overly mono system. For each in
- * coming channel the data comes in from the codec, through a 'input'
- * APU, through another rate converter APU, and then into memory via
- * the wavecache and PCI. If its stereo, we mash it back into LRLR in
- * software. The pass between the 2 APUs is supposedly what requires us
- * to have a 512 byte buffer sitting around in wavecache/memory.
- *
- * The wavecache makes our life even more fun. First off, it can
- * only address the first 28 bits of PCI address space, making it
- * useless on quite a few architectures. Secondly, its insane.
- * It claims to fetch from 4 regions of PCI space, each 4 meg in length.
- * But that doesn't really work. You can only use 1 region. So all our
- * allocations have to be in 4meg of each other. Booo. Hiss.
- * So we have a module parameter, dsps_order, that is the order of
- * the number of dsps to provide. All their buffer space is allocated
- * on open time. The sonicvibes OSS routines we inherited really want
- * power of 2 buffers, so we have all those next to each other, then
- * 512 byte regions for the recording wavecaches. This ends up
- * wasting quite a bit of memory. The only fixes I can see would be
- * getting a kernel allocator that could work in zones, or figuring out
- * just how to coerce the WP into doing what we want.
- *
- * The indirection of the various registers means we have to spinlock
- * nearly all register accesses. We have the main register indirection
- * like the wave cache, maestro registers, etc. Then we have beasts
- * like the APU interface that is indirect registers gotten at through
- * the main maestro indirection. Ouch. We spinlock around the actual
- * ports on a per card basis. This means spinlock activity at each IO
- * operation, but the only IO operation clusters are in non critical
- * paths and it makes the code far easier to follow. Interrupts are
- * blocked while holding the locks because the int handler has to
- * get at some of them :(. The mixer interface doesn't, however.
- * We also have an OSS state lock that is thrown around in a few
- * places.
- *
- * This driver has brute force APM suspend support. We catch suspend
- * notifications and stop all work being done on the chip. Any people
- * that try between this shutdown and the real suspend operation will
- * be put to sleep. When we resume we restore our software state on
- * the chip and wake up the people that were using it. The code thats
- * being used now is quite dirty and assumes we're on a uni-processor
- * machine. Much of it will need to be cleaned up for SMP ACPI or
- * similar.
- *
- * We also pay attention to PCI power management now. The driver
- * will power down units of the chip that it knows aren't needed.
- * The WaveProcessor and company are only powered on when people
- * have /dev/dsp*s open. On removal the driver will
- * power down the maestro entirely. There could still be
- * trouble with BIOSen that magically change power states
- * themselves, but we'll see.
- *
- * History
- * v0.15 - May 21 2001 - Marcus Meissner <mm@caldera.de>

- * I need to thank many people for helping make this driver happen.
- * As always, Eric Brombaugh was a hacking machine and killed many bugs
- * that I was too dumb to notice. Howard Kim at ESS provided reference boards
- * and as much docs as he could. Todd and Mick at Dell tested snapshots on
- * an army of laptops. msw and deviant at Red Hat also humoured me by hanging
- * their laptops every few hours in the name of science.
- *
- * Shouts go out to Mike "DJ XPCom" Ang.
- *
- * History
- * v1.23 - Jun 5 2002 - Michael Olson <olson@cs.odu.edu>
- * added a module option to allow selection of GPIO pin number
- * for external amp
- * v1.22 - Feb 28 2001 - Zach Brown <zab@zabbo.net>
- * allocate mem at insmod/setup, rather than open
- * limit pci dma addresses to 28bit, thanks guys.
- * v1.21 - Feb 04 2001 - Zach Brown <zab@zabbo.net>
- * fix up really dumb notifier -> suspend oops
- * v1.20 - Jan 30 2001 - Zach Brown <zab@zabbo.net>
- * get rid of pm callback and use pci_dev suspend/resume instead
- * m3_probe cleanups, including pm oops think-o
- * v1.10 - Jan 6 2001 - Zach Brown <zab@zabbo.net>
- * revert to lame remap_page_range mmap() just to make it work
- * record mmap fixed.
- * fix up incredibly broken open/release resource management
- * duh. fix record format setting.
- * add SMP locking and cleanup formatting here and there
- * v1.00 - Dec 16 2000 - Zach Brown <zab@zabbo.net>
- * port to sexy 2.4 interfaces
- * properly align instance allocations so recording works
- * clean up function namespace a little :/
- * update PCI IDs based on mail from ESS
- * arbitrarily bump version number to show its 2.4 now,
- * 2.2 will stay 0., oss_audio port gets 2.
- * v0.03 - Nov 05 2000 - Zach Brown <zab@zabbo.net>
- * disable recording but allow dsp to be opened read
- * pull out most silly compat defines
- * v0.02 - Nov 04 2000 - Zach Brown <zab@zabbo.net>
- * changed clocking setup for m3, slowdown fixed.
- * codec reset is hopefully reliable now
- * rudimentary apm/power management makes suspend/resume work
- * v0.01 - Oct 31 2000 - Zach Brown <zab@zabbo.net>
- * first release
- * v0.00 - Sep 09 2000 - Zach Brown <zab@zabbo.net>
- * first pass derivation from maestro.c
- *
- * TODO
- * in/out allocated contiguously so fullduplex mmap will work?
- * no beep on init (mute)
- * resetup msrc data memory if freq changes?
- *
- * --
- *
- * Allow me to ramble a bit about the m3 architecture. The core of the
- * chip is the 'assp', the custom ESS dsp that runs the show. It has
- * a small amount of code and data ram. ESS drops binary dsp code images
- * on our heads, but we don't get to see specs on the dsp.
- *
- * The constant piece of code on the dsp is the 'kernel'. It also has a
- * chunk of the dsp memory that is statically set aside for its control
- * info. This is the KDATA defines in maestro3.h. Part of its core
- * data is a list of code addresses that point to the pieces of DSP code
- * that it should walk through in its loop. These other pieces of code
- * do the real work. The kernel presumably jumps into each of them in turn.
- * These code images tend to have their own data area, and one can have
- * multiple data areas representing different states for each of the 'client
- * instance' code portions. There is generally a list in the kernel data
- * that points to the data instances for a given piece of code.
- *
- * We've only been given the binary image for the 'minisrc', mini sample
- * rate converter. This is rather annoying because it limits the work
- * we can do on the dsp, but it also greatly simplifies the job of managing
- * dsp data memory for the code and data for our playing streams :). We
- * statically allocate the minisrc code into a region we 'know' to be free
- * based on the map of the binary kernel image we're loading. We also
- * statically allocate the data areas for the maximum number of pcm streams
- * we can be dealing with. This max is set by the length of the static list
- * in the kernel data that records the number of minisrc data regions we
- * can have. Thats right, all software dsp mixing with static code list
- * limits. Rock.
- *
- * How sound goes in and out is still a relative mystery. It appears
- * that the dsp has the ability to get input and output through various
- * 'connections'. To do IO from or to a connection, you put the address
- * of the minisrc client area in the static kernel data lists for that
- * input or output. so for pcm -> dsp -> mixer, we put the minisrc data
- * instance in the DMA list and also in the list for the mixer. I guess
- * it Just Knows which is in/out, and we give some dma control info that
- * helps. There are all sorts of cool inputs/outputs that it seems we can't
- * use without dsp code images that know how to use them.
- *
- * So at init time we preload all the memory allocation stuff and set some
- * system wide parameters. When we really get a sound to play we build
- * up its minisrc header (stream parameters, buffer addresses, input/output
- * settings). Then we throw its header on the various lists. We also
- * tickle some KDATA settings that ask the assp to raise clock interrupts
- * and do some amount of software mixing before handing data to the ac97.
- *
- * Sorry for the vague details. Feel free to ask Eric or myself if you
- * happen to be trying to use this driver elsewhere. Please accept my
- * apologies for the quality of the OSS support code, its passed through
- * too many hands now and desperately wants to be rethought.

- * 27 Apr 2001: 0.3 more than one card usable
- * 11 May 2001: 0.4 fixed for SMP, included into kernel source tree
- * 17 May 2001: 0.5 draining code didn't work on new cards
- * 18 May 2001: 0.6 remove synchronize_irq() call
- * 17 Jul 2001: 0.7 updated xrmectrl to make it work for newer cards
- * 2 feb 2002: 0.8 fixed pci device handling, see below for patches from Heiko (Thanks!)
- Marcus Meissner <Marcus.Meissner@caldera.de>
-
- Modifications - Heiko Purnhagen <purnhage@tnt.uni-hannover.de>
- HP20020108 fixed handling of "large" read()
- HP20020116 towards REV 1.5 support, based on ALSA's card-rme9652.c
- HP20020118 made mixer ioctl and handling of devices>1 more safe
- HP20020201 fixed handling of "large" read() properly
- added REV 1.5 S/P-DIF receiver support
- SNDCTL_DSP_SPEED now returns the actual speed
- * 10 Aug 2002: added synchronize_irq() again
-
-TODO:
- - test more than one card --- done
- - check for pci IOREGION (see es1370) in rme96xx_probe ??
- - error detection
- - mmap interface
- - mixer mmap interface
- - mixer ioctl
- - get rid of noise upon first open (why ??)
- - allow multiple open (at least for read)
- - allow multiple open for non overlapping regions
- - recheck the multiple devices part (offsets of different devices, etc)
- - do decent draining in _release --- done
- - SMP support
- - what about using fragstotal>2 for small fragsize? (HP20020118)
- - add support for AFMT_S32_LE

- *
- * Special thanks to David C. Niemi
- *
- *
- * Module command line parameters:
- * none so far
- *
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * The card has both an FM and a Wavetable synth, but I have to figure
- * out first how to drive them...
- *
- * Revision history
- * 06.05.1998 0.1 Initial release
- * 10.05.1998 0.2 Fixed many bugs, esp. ADC rate calculation
- * First stab at a simple midi interface (no bells&whistles)
- * 13.05.1998 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
- * set_dac_rate in the FMODE_WRITE case in sv_open
- * Fix hwptr out of bounds (now mpg123 works)
- * 14.05.1998 0.4 Don't allow excessive interrupt rates
- * 08.06.1998 0.5 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.1998 0.6 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.1998 0.7 Fix realplayer problems - dac.count issues
- * 10.12.1998 0.8 Fix drain_dac trying to wait on not yet initialized DMA
- * 16.12.1998 0.9 Fix a few f_file & FMODE_ bugs
- * 06.01.1999 0.10 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.1999 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.1999 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 05.04.1999 0.13 added code to sv_read and sv_write which should detect
- * lockups of the sound chip and revive it. This is basically
- * an ugly hack, but at least applications using this driver
- * won't hang forever. I don't know why these lockups happen,
- * it might well be the motherboard chipset (an early 486 PCI
- * board with ALI chipset), since every busmastering 100MB
- * ethernet card I've tried (Realtek 8139 and Macronix tulip clone)
- * exhibit similar behaviour (they work for a couple of packets
- * and then lock up and can be revived by ifconfig down/up).
- * 07.04.1999 0.14 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * Note: dmaio hack might still be wrong on archs other than i386
- * 15.06.1999 0.15 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.16 Add pci_set_master
- * 03.08.1999 0.17 adapt to Linus' new __setup/__initcall
- * added kernel command line options "sonicvibes=reverb" and "sonicvibesdmaio=dmaioaddr"
- * 12.08.1999 0.18 module_init/__setup fixes
- * 24.08.1999 0.19 get rid of the dmaio kludge, replace with allocate_resource
- * 31.08.1999 0.20 add spin_lock_init
- * use new resource allocation to allocate DDMA IO space
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.21 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 28.10.1999 0.22 More waitqueue races fixed
- * 01.12.1999 0.23 New argument to allocate_resource
- * 07.12.1999 0.24 More allocate_resource semantics change
- * 08.01.2000 0.25 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * use Martin Mares' pci_assign_resource
- * 07.02.2000 0.26 Use pci_alloc_consistent and pci_register_driver
- * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask

- *
- * sound/wavfront.c
- *
- * A Linux driver for Turtle Beach WaveFront Series (Maui, Tropez, Tropez Plus)
- *
- * This driver supports the onboard wavetable synthesizer (an ICS2115),
- * including patch, sample and program loading and unloading, conversion
- * of GUS patches during loading, and full user-level access to all
- * WaveFront commands. It tries to provide semi-intelligent patch and
- * sample management as well.
- *
- * It also provides support for the ICS emulation of an MPU-401. Full
- * support for the ICS emulation's "virtual MIDI mode" is provided in
- * wf_midi.c.
- *
- * Support is also provided for the Tropez Plus' onboard FX processor,
- * a Yamaha YSS225. Currently, code exists to configure the YSS225,
- * and there is an interface allowing tweaking of any of its memory
- * addresses. However, I have been unable to decipher the logical
- * positioning of the configuration info for various effects, so for
- * now, you just get the YSS225 in the same state as Turtle Beach's
- * "SETUPSND.EXE" utility leaves it.
- *
- * The boards' DAC/ADC (a Crystal CS4232) is supported by cs4232.[co],
- * This chip also controls the configuration of the card: the wavefront
- * synth is logical unit 4.
- *
- *
- * Supported devices:
- *
- * /dev/dsp - using cs4232+ad1848 modules, OSS compatible
- * /dev/midiNN and /dev/midiNN+1 - using wf_midi code, OSS compatible
- * /dev/synth00 - raw synth interface
- *

-Sometimes, we need to munge numeric values that are represented on

- * sound/oss/wf_midi.c
- *
- * The low level driver for the WaveFront ICS2115 MIDI interface(s)
- * Note that there is also an MPU-401 emulation (actually, a UART-401
- * emulation) on the CS4232 on the Tropez Plus. This code has nothing
- * to do with that interface at all.
- *
- * The interface is essentially just a UART-401, but is has the
- * interesting property of supporting what Turtle Beach called
- * "Virtual MIDI" mode. In this mode, there are effectively *two*
- * MIDI buses accessible via the interface, one that is routed
- * solely to/from the external WaveFront synthesizer and the other
- * corresponding to the pin/socket connector used to link external
- * MIDI devices to the board.
- *
- * This driver fully supports this mode, allowing two distinct
- * midi devices (/dev/midiNN and /dev/midiNN+1) to be used
- * completely independently, giving 32 channels of MIDI routing,
- * 16 to the WaveFront synth and 16 to the external MIDI bus.
- *
- * Switching between the two is accomplished externally by the driver
- * using the two otherwise unused MIDI bytes. See the code for more details.
- *
- * NOTE: VIRTUAL MIDI MODE IS ON BY DEFAULT (see wavefront.c)
- *
- * The main reason to turn off Virtual MIDI mode is when you want to
- * tightly couple the WaveFront synth with an external MIDI
- * device. You won't be able to distinguish the source of any MIDI
- * data except via SysEx ID, but thats probably OK, since for the most
- * part, the WaveFront won't be sending any MIDI data at all.
- *
- * The main reason to turn on Virtual MIDI Mode is to provide two
- * completely independent 16-channel MIDI buses, one to the
- * WaveFront and one to any external MIDI devices. Given the 32
- * voice nature of the WaveFront, its pretty easy to find a use
- * for all 16 channels driving just that synth.
- *

- * TODO:
- * - Use P44Slot for 44.1 playback (beware of idle buzzing in P44Slot).
- * - 96KHz playback for DVD - use pitch of 2.0.
- * - Retain DMA buffer on close, do not wait the end of frame.
- * - Resolve XXX tagged questions.
- * - Cannot play 5133Hz.
- * - 2001/01/07 Consider if we can remove voice_lock, like so:
- * : Allocate/deallocate voices in open/close under semafore.
- * : We access voices in interrupt, that only for pcms that open.
- * voice_lock around playback_prepare closes interrupts for insane duration.
- * - Revisit the way voice_alloc is done - too confusing, overcomplicated.
- * Should support various channel types, however.
- * - Remove prog_dmabuf from read/write, leave it in open.
- * - 2001/01/07 Replace the OPL3 part of CONFIG_SOUND_YMFPCI_LEGACY code with
- * native synthesizer through a playback slot.
- * - 2001/11/29 ac97_save_state
- * Talk to Kai to remove ac97_save_state before it's too late!
- * - Second AC97
- * - Restore S/PDIF - Toshibas have it.
- *
- * Kai used pci_alloc_consistent for DMA buffer, which sounds a little
- * unconventional. However, given how small our fragments can be,
- * a little uncached access is perhaps better than endless flushing.
- * On i386 and other I/O-coherent architectures pci_alloc_consistent
- * is entirely harmless.
