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