-        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.

-
-STEPS TO BUILD DRIVER
-================================================================================
-
-  1. Backup the Config.in and Makefile in the sound driver directory
-     (/usr/src/linux/driver/sound).
-     The Configure.help provide help when you config driver in step
-     4, please backup the original one (/usr/src/linux/Document) and
-     copy this file.
-     The cmpci is document for the driver in detail, please copy it
-     to /usr/src/linux/Document/sound so you can refer it. Backup if
-     there is already one.
-
-  2. Extract the tar file by 'tar xvzf cmpci-xx.tar.gz' in the above
-     directory.
-
-  3. Change directory to /usr/src/linux
-
-  4. Config cm8338 driver by 'make menuconfig', 'make config' or
-     'make xconfig' command.
-
-  5. Please select Sound Card (CONFIG_SOUND=m) support and CMPCI
-     driver (CONFIG_SOUND_CMPCI=m) as modules. Resident mode not tested.
-     For driver option, please refer 'DRIVER PARAMETER'
-
-  6. Compile the kernel if necessary.
-
-  7. Compile the modules by 'make modules'.
-
-  8. Install the modules by 'make modules_install'
-
-
-INSTALL DRIVER
-================================================================================
-
-  1. Before first time to run the driver, create module dependency by
-     'depmod -a'
-
-  2. To install the driver manually, enter 'modprobe cmpci'.
-
-  3. Driver installation for various distributions:
-
-    a. Slackware 4.0
-       Add the 'modprobe cmpci' command in your /etc/rc.d/rc.modules
-       file.so you can start the driver automatically each time booting.
-
-    b. Caldera OpenLinux 2.2
-       Use LISA to load the cmpci module.
-
-    c. RedHat 6.0 and S.u.S.E. 6.1
-       Add following command in /etc/conf.modules:
-
-       alias sound cmpci
-
-        also visit http://www.cmedia.com.tw for installation instruction.
-
-DRIVER PARAMETER
-================================================================================
-
-  Some functions for the cm8738 can be configured in Kernel Configuration
-  or modules parameters. Set these parameters to 1 to enable.
-
-  mpuio:        I/O ports base for MPU-401, 0 if disabled.
-  fmio:         I/O ports base for OPL-3, 0 if disabled.
-  spdif_inverse:Inverse the S/PDIF-in signal, this depends on your
-                CD-ROM or DVD-ROM.
-  spdif_loop:   Enable S/PDIF loop, this route S/PDIF-in to S/PDIF-out
-                directly.
-  speakers:     Number of speakers used.
-  use_line_as_rear:Enable this if you want to use line-in as
-                rear-out.
-  use_line_as_bass:Enable this if you want to use line-in as
-                bass-out.
-  joystick:     Enable joystick. You will need to install Linux joystick
-                driver.

-        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.
-
-.. more details ..

-
-drivers/sound/maestro.c contains comments that hopefully explain
-the maestro implementation.

-        An OSS/Lite Driver for the ESS Maestro3 family of sound chips
-
-                        Zach Brown, January 2001
-
-Driver Status and Availability

-
-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.

-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.
-
-
-* ACKNOWLEDGMENTS

-                          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.

-**********************************************************************
-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
-   .
-   .

-************************************************************
-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)

-/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.

-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.

----------
-
-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
-  never been copied (just mmap-ed into user space straight from the
-  disk), it would be nice to allow handling of multi-channel sample
-  data without forcing user-level extraction of the relevant bytes.
-  
-  So, we need a way of specifying which channel to use (the WaveFront
-  only handles mono samples in a given slot), and the only way to do
-  this without using some struct other than wavefront_sample as the
-  interface is the awful hack of using the unused bits in a
-  wavefront_sample:
-  
-  Val      Meaning
-  ---      -------
-  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 ...

- *      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

- *
- *  Revision history
- *    06.27.2001  Initial version
- *    03.20.2002  Added mutex locks around read/write methods, to prevent
- *                simultaneous access on SMP or preemptible kernels. Also
- *                removed the counter/pointer fragment aligning at the end
- *                of read/write methods [stevel].
- *    03.21.2002  Add support for coherent DMA on the audio read/write DMA
- *                channels [stevel].

- * 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

- *      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

-*
-*  Supported devices:

-*
-* 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.

- *
- * 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

- * 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

- *
- *  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>

-
-        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.

-                return the real values
-        - add private ioctl for selecting line- or microphone input
-                (only one of them is available at the same time)
-        - add module parameters
-        - implement mmap functionality
-        - implement gain meter ?

- *      OAK OTI-601D    Mozart

- *      OPTi 82C929     MAD16 Pro
- *      OPTi 82C930
- *      OPTi 82C924
- *
- * These audio interface chips don't produce sound themselves. They just
- * connect some other components (OPL-[234] and a WSS compatible codec)
- * to the PC bus and perform I/O, DMA and IRQ address decoding. There is
- * also a UART for the MPU-401 mode (not 82C928/Mozart).
- * The Mozart chip appears to be compatible with the 82C928, although later
- * issues of the card, using the OTI-605 chip, have an MPU-401 compatible Midi
- * port. This port is configured differently to that of the OPTi audio chips.
- *
- *      Changes
- *      
- *      Alan Cox                Clean up, added module selections.
- *
- *      A. Wik                  Added support for Opti924 PnP.
- *                              Improved debugging support.     16-May-1998
- *                              Fixed bug.                      16-Jun-1998
- *
- *      Torsten Duwe            Made Opti924 PnP support non-destructive

- *
- *      Paul Grayson            Added support for Midi on later Mozart cards.
- *                                                              25-Nov-1999
- *      Christoph Hellwig       Adapted to module_init/module_exit.

- *  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>
- *      Ported to Linux 2.4 PCI API. Some clean ups, global devs list
- *      removed (now using pci device driver data).
- *      PM needs to be polished still. Bumped version.
- *  (still kind of v0.14) May 13 2001 - Ben Pfaff <pfaffben@msu.edu>
- *      Add support for 978 docking and basic hardware volume control
- *  (still kind of v0.14) Nov 23 - Alan Cox <alan@redhat.com>
- *      Add clocking= for people with seriously warped hardware
- *  (still v0.14) Nov 10 2000 - Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
- *      add __init to maestro_ac97_init() and maestro_install()
- *  (still based on v0.14) Mar 29 2000 - Zach Brown <zab@redhat.com>
- *      move to 2.3 power management interface, which
- *              required hacking some suspend/resume/check paths 
- *      make static compilation work
- *  v0.14 - Jan 28 2000 - Zach Brown <zab@redhat.com>
- *      add PCI power management through ACPI regs.
- *      we now shut down on machine reboot/halt
- *      leave scary PCI config items alone (isa stuff, mostly)
- *      enable 1921s, it seems only mine was broke.
- *      fix swapped left/right pcm dac.  har har.
- *      up bob freq, increase buffers, fix pointers at underflow
- *      silly compilation problems
- *  v0.13 - Nov 18 1999 - Zach Brown <zab@redhat.com>
- *      fix nec Versas?  man would that be cool.
- *  v0.12 - Nov 12 1999 - Zach Brown <zab@redhat.com>
- *      brown bag volume max fix..
- *  v0.11 - Nov 11 1999 - Zach Brown <zab@redhat.com>
- *      use proper stereo apu decoding, mmap/write should work.
- *      make volume sliders more useful, tweak rate calculation.
- *      fix lame 8bit format reporting bug.  duh. apm apu saving buglet also
- *      fix maestro 1 clock freq "bug", remove pt101 support
- *  v0.10 - Oct 28 1999 - Zach Brown <zab@redhat.com>
- *      aha, so, sometimes the WP writes a status word to offset 0
- *        from one of the PCMBARs.  rearrange allocation accordingly..
- *        cheers again to Eric for being a good hacker in investigating this.
- *      Jeroen Hoogervorst submits 7500 fix out of nowhere.  yay.  :)
- *  v0.09 - Oct 23 1999 - Zach Brown <zab@redhat.com>
- *      added APM support.
- *      re-order something such that some 2Es now work.  Magic!
- *      new codec reset routine.  made some codecs come to life.
- *      fix clear_advance, sync some control with ESS.
- *      now write to all base regs to be paranoid.
- *  v0.08 - Oct 20 1999 - Zach Brown <zab@redhat.com>
- *      Fix initial buflen bug.  I am so smart.  also smp compiling..

- *      tweak adc/dac, formating, and stuff to allow full duplex
- *      allocate dsps memory at open() so we can fit in the wavecache window
- *      fix wavecache braindamage.  again.  no more scribbling?
- *      fix ess 1921 codec bug on some laptops.
- *      fix dumb pci scanning bug
- *      started 2.3 cleanup, redid spinlocks, little cleanups
- *  v0.06 - Sep 20 1999 - Zach Brown <zab@redhat.com>
- *      fix wavecache thinkos.  limit to 1 /dev/dsp.
- *      eric is wearing his thinking toque this week.
- *              spotted apu mode bugs and gain ramping problem
- *      don't touch weird mixer regs, make recmask optional
- *      fixed igain inversion, defaults for mixers, clean up rec_start
- *      make mono recording work.
- *      report subsystem stuff, please send reports.
- *      littles: parallel out, amp now
- *  v0.05 - Sep 17 1999 - Zach Brown <zab@redhat.com>
- *      merged and fixed up Eric's initial recording code
- *      munged format handling to catch misuse, needs rewrite.
- *      revert ring bus init, fixup shared int, add pci busmaster setting
- *      fix mixer oss interface, fix mic mute and recmask
- *      mask off unsupported mixers, reset with all 1s, modularize defaults
- *      make sure bob is running while we need it
- *      got rid of device limit, initial minimal apm hooks
- *      pull out dead code/includes, only allow multimedia/audio maestros
- *  v0.04 - Sep 01 1999 - Zach Brown <zab@redhat.com>
- *      copied memory leak fix from sonicvibes driver
- *      different ac97 reset, play with 2.0 ac97, simplify ring bus setup
- *      bob freq code, region sanity, jitter sync fix; all from Eric 
- *
- * TODO
- *      fix bob frequency
- *      endianness
- *      do smart things with ac97 2.0 bits.
- *      dual codecs
- *      leave 54->61 open
- *
- *      it also would be fun to have a mode that would not use pci dma at all
- *      but would copy into the wavecache on board memory and use that 
- *      on architectures that don't like the maestro's pci dma ickiness.

- * 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.

-                       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

- *
- *
- *  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
- *    12.12.2000   0.28  More dma buffer initializations, patch from
- *                       Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- *    31.01.2001   0.29  Register/Unregister gameport
- *                       Fix SETTRIGGER non OSS API conformity
- *    18.05.2001   0.30  PCI probing and error values cleaned up by Marcus
- *                       Meissner <mm@caldera.de>
- *    03.01.2003   0.31  open_mode fixes from Georg Acher <acher@in.tum.de>

-/*  -*- linux-c -*-
- *
- * 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
- *

-WaveFront: data munging   
-
-Things here are weird. All data written to the board cannot 
-have its most significant bit set. Any data item with values 
-potentially > 0x7F (127) must be split across multiple bytes.
-
-Sometimes, we need to munge numeric values that are represented on
-the x86 side as 8-32 bit values. Sometimes, we need to munge data
-that is represented on the x86 side as an array of bytes. The most
-efficient approach to handling both cases seems to be to use 2
-different functions for munging and 2 for de-munging. This avoids
-weird casting and worrying about bit-level offsets.

-                   so anyone is free at all times to rewrite sample headers.
-
-                   My reason for this is that we have the sample headers
-                   available in the WFB file for General MIDI, and so these
-                   can always be reset if needed. The sample data, however,
-                   cannot be recovered without a complete reset and firmware
-                   reload of the ICS2115, which is a very expensive operation.
-
-                   So, doing things this way allows us to honor the notion of
-                   "RESETSAMPLES" reasonably cheaply. Note however, that this
-                   is done purely at user level: there is no WFB parser in
-                   this driver, and so a complete reset (back to General MIDI,
-                   or theoretically some other configuration) is the
-                   responsibility of the user level library. 
-
-                   To try to do this in the kernel would be a little
-                   crazy: we'd need 158K of kernel space just to hold
-                   a copy of the patch/program/sample header data.

-           doing busy and/or sleep-waiting. Alas, it appears that once
-           the Motorola firmware is downloaded, the card *never*
-           generates an RX interrupt. These are successfully generated
-           during firmware loading, and after that wavefront_status()
-           reports that an interrupt is pending on the card from time
-           to time, but it never seems to be delivered to this
-           driver. Note also that wavefront_status() continues to
-           report that RX interrupts are enabled, suggesting that I
-           didn't goof up and disable them by mistake.
-
-           Thus, I stepped back to a prior version of
-           wavefront_wait(), the only place where this really
-           matters. Its sad, but I've looked through the code to check
-           on things, and I really feel certain that the Motorola
-           firmware prevents RX-ready interrupts.

-   to add more logic to the code. Its really pretty weird.

-   There was an alternative approach of just dumping the whole I/O
-   sequence as a series of port/value pairs and a simple loop

- * 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.
