/*
|
|
* Software state, per SoundBlaster card.
|
|
* The soundblaster has multiple functionality, which we must demultiplex.
|
|
* One approach is to have one major device number for the soundblaster card,
|
|
* and use different minor numbers to indicate which hardware function
|
|
* we want. This would make for one large driver. Instead our approach
|
|
* is to partition the design into a set of drivers that share an underlying
|
|
* piece of hardware. Most things are hard to share, for example, the audio
|
|
* and midi ports. For audio, we might want to mix two processes' signals,
|
|
* and for midi we might want to merge streams (this is hard due to
|
|
* running status). Moreover, we should be able to re-use the high-level
|
|
* modules with other kinds of hardware. In this module, we only handle the
|
|
* most basic communications with the sb card.
