This would make for one large driver. Instead our approach 86 * is to partition the design into a set of drivers that share an underlying 87 * piece of hardware. Most things are hard to share, for example, the audio 88 * and midi ports. For audio, we might want to mix two processes' signals, 89 * and for midi we might want to merge streams (this is hard due to 90 * running status). Moreover, we should be able to re-use the high-level 91 * modules with other kinds of hardware. In this module, we only handle the 92 * most basic communications with the sb card. 93 */ 94 struct sbdsp_softc { 95 device_t sc_dev; /* base device */ 96 isa_chipset_tag_t sc_ic; 97 bus_space_tag_t sc_iot;
