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. 96 */ 97struct sbdsp_softc { 98 struct device sc_dev; /* base device */ 99 struct isadev sc_id; /* ISA device */ 100 isa_chipset_tag_t sc_ic;
