12 | * An ALSA lowlevel driver for Turtle Beach ICS2115 wavetable synth | |
13 | * (Maui, Tropez, Tropez Plus) | |
14 | * | |
15 | * This driver supports the onboard wavetable synthesizer (an ICS2115), | |
16 | * including patch, sample and program loading and unloading, conversion | |
17 | * of GUS patches during loading, and full user-level access to all | |
18 | * WaveFront commands. It tries to provide semi-intelligent patch and | |
19 | * sample management as well. | |

511 | WaveFront data munging | |
512 | ||
513 | Things here are weird. All data written to the board cannot | |
514 | have its most significant bit set. Any data item with values | |
515 | potentially > 0x7F (127) must be split across multiple bytes. | |
516 | ||
517 | Sometimes, we need to munge numeric values that are represented on | |
518 | the x86 side as 8-32 bit values. Sometimes, we need to munge data | |
519 | that is represented on the x86 side as an array of bytes. The most | |
520 | efficient approach to handling both cases seems to be to use 2 | |
521 | different functions for munging and 2 for de-munging. This avoids | |
522 | weird casting and worrying about bit-level offsets. | |

912 | So, doing things this way allows us to honor the notion of | |
913 | "RESETSAMPLES" reasonably cheaply. Note however, that this | |
914 | is done purely at user level: there is no WFB parser in | |
915 | this driver, and so a complete reset (back to General MIDI, | |
916 | or theoretically some other configuration) is the | |
917 | responsibility of the user level library. | |
918 | ||

920 | crazy: we'd need 158K of kernel space just to hold | |
