*
|
||
* 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.

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.
