| 3 | * sound/wavfront.c |
| 4 | * |
| 5 | * A Linux driver for Turtle Beach WaveFront Series (Maui, Tropez, Tropez Plus) |
| 6 | * |
| 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. |
| 12 | * |
| 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 |
| 15 | * wf_midi.c. |
| 16 | * |
| 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. |
| 24 | * |
| 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. |
| 28 | * |
| 29 | * |
| 30 | * Supported devices: |
| 31 | * |
| 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 |

| 43 | * Although the relevant code here is all new, the handling of |

| 47 | * unaltered by me, except to fit formatting and function names in the |
| 48 | * rest of the file. Many thanks to them. |
| 49 | * |
| 50 | * Appreciation and thanks to Hannu Savolainen for his early work on the Maui |
| 51 | * driver, and answering a few questions while this one was developed. |
| 52 | * |
| 53 | * Absolutely NO thanks to Turtle Beach/Voyetra and Yamaha for their |
| 54 | * complete lack of help in developing this driver, and in particular |
| 55 | * for their utter silence in response to questions about undocumented |
| 56 | * aspects of configuring a WaveFront soundcard, particularly the |
| 57 | * effects processor. |

| 653 | WaveFront: data munging |
| 654 | |
| 655 | Things here are weird. All data written to the board cannot |
| 656 | have its most significant bit set. Any data item with values |
| 657 | potentially > 0x7F (127) must be split across multiple bytes. |
| 658 | |
| 659 | Sometimes, we need to munge numeric values that are represented on |
| 660 | the x86 side as 8-32 bit values. Sometimes, we need to munge data |
| 661 | that is represented on the x86 side as an array of bytes. The most |
| 662 | efficient approach to handling both cases seems to be to use 2 |
| 663 | different functions for munging and 2 for de-munging. This avoids |
| 664 | weird casting and worrying about bit-level offsets. |

| 1050 | |
| 1051 | My reason for this is that we have the sample headers |
| 1052 | available in the WFB file for General MIDI, and so these |
| 1053 | can always be reset if needed. The sample data, however, |
| 1054 | cannot be recovered without a complete reset and firmware |
| 1055 | reload of the ICS2115, which is a very expensive operation. |
| 1056 | |
| 1057 | So, doing things this way allows us to honor the notion of |
| 1058 | "RESETSAMPLES" reasonably cheaply. Note however, that this |
| 1059 | is done purely at user level: there is no WFB parser in |
| 1060 | this driver, and so a complete reset (back to General MIDI, |
| 1061 | or theoretically some other configuration) is the |
| 1062 | responsibility of the user level library. |
| 1063 | |
| 1064 | To try to do this in the kernel would be a little |
| 1065 | crazy: we'd need 158K of kernel space just to hold |
| 1066 | a copy of the patch/program/sample header data. |
