|
|
|
|
* 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

I consider /dev/sequencer to be an anachronism, but given its
|
|
|
|
|
|
widespread usage by various Linux MIDI software, it seems worth
|
|
|
|
|
|
offering support to it if it's not too painful. Instead of using
|
|
|
|
|
|
/dev/sequencer, I recommend:
|
|
|
|
|
|
|
|
|
|
|
|
for synth programming and patch loading: /dev/synthNN
|
|
|
|
|
|
for kernel-synchronized MIDI sequencing: the ALSA sequencer
|
|
|
|
|
|
for direct MIDI control: /dev/midiNN
|
|
|
|
|
|
|
|
|
|
|
|
I have never tried static compilation into the kernel. The #if's
|
|
|
|
|
|
for this are really just notes to myself about what the code is
|
|
|
|
|
|
for.

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.

|
|
|
|
|
|
on the ROM samples should cover just the sample data or
|
|
|
|
|
|
the sample header. For now, it only covers the sample data,
|
|
|
|
|
|
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.

Some comments on interrupts. I attempted a version of this
|
|
|
|
|
|
driver that used interrupts throughout the code instead of
|
|
|
|
|
|
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.

interrupt. This can take a *long* time after a cold boot,

while the ISC ROM does its RAM test. The SDK says up to 4

seconds - with 12MB of RAM on a Tropez+, it takes a lot

longer than that (~16secs). Note that the card understands

the difference between a warm and a cold boot, so

subsequent ISC2115 reboots (say, caused by module

reloading) will get through this much faster.

/* YSS225 initialization.
|
|
|
|
|
|
|
|
|
|
|
|
This code was developed using DOSEMU. The Turtle Beach SETUPSND
|
|
|
|
|
|
utility was run with I/O tracing in DOSEMU enabled, and a reconstruction
|
|
|
|
|
|
of the port I/O done, using the Yamaha faxback document as a guide
|
|
|
|
|
|
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
|
|
|
|
|
|
that output it. However, I hope that eventually I'll get more
|
|
|
|
|
|
control over what this code does, and so I tried to stick with
|
|
|
|
|
|
a somewhat "algorithmic" approach.
