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

656 Things here are weird. All data written to the board cannot

658 potentially > 0x7F (127) must be split across multiple bytes.
660 Sometimes, we need to munge numeric values that are represented on

662 that is represented on the x86 side as an array of bytes. The most
663 efficient approach to handling both cases seems to be to use 2
664 different functions for munging and 2 for de-munging. This avoids

1052 My reason for this is that we have the sample headers
1053 available in the WFB file for General MIDI, and so these
1054 can always be reset if needed. The sample data, however,
1055 cannot be recovered without a complete reset and firmware
1056 reload of the ICS2115, which is a very expensive operation.
1058 So, doing things this way allows us to honor the notion of
1059 "RESETSAMPLES" reasonably cheaply. Note however, that this
1060 is done purely at user level: there is no WFB parser in
1061 this driver, and so a complete reset (back to General MIDI,
1062 or theoretically some other configuration) is the
1063 responsibility of the user level library.
1065 To try to do this in the kernel would be a little
1066 crazy: we'd need 158K of kernel space just to hold

2143 Some comments on interrupts. I attempted a version of this
2144 driver that used interrupts throughout the code instead of
2145 doing busy and/or sleep-waiting. Alas, it appears that once
2146 the Motorola firmware is downloaded, the card *never*
2147 generates an RX interrupt. These are successfully generated
2148 during firmware loading, and after that wavefront_status()
2149 reports that an interrupt is pending on the card from time
2150 to time, but it never seems to be delivered to this
2151 driver. Note also that wavefront_status() continues to
2152 report that RX interrupts are enabled, suggesting that I
2153 didn't goof up and disable them by mistake.
2155 Thus, I stepped back to a prior version of
2156 wavefront_wait(), the only place where this really
2157 matters. Its sad, but I've looked through the code to check
2158 on things, and I really feel certain that the Motorola
2159 firmware prevents RX-ready interrupts.

3045 of the port I/O done, using the Yamaha faxback document as a guide
3046 to add more logic to the code. Its really pretty weird.

3049 sequence as a series of port/value pairs and a simple loop
3050 that output it. However, I hope that eventually I'll get more
