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