This would make for one large driver. Instead our approach 65 * is to partition the design into a set of drivers that share an underlying 66 * piece of hardware. Most things are hard to share, for example, the audio 67 * and midi ports. For audio, we might want to mix two processes' signals, 68 * and for midi we might want to merge streams (this is hard due to 69 * running status). Moreover, we should be able to re-use the high-level 70 * modules with other kinds of hardware. In this module, we only handle the 71 * most basic communications with the sb card. 72 */ 73 struct sbdsp_softc { 74 struct device sc_dev; /* base device */ 75 struct isadev sc_id; /* ISA device */ 76 isa_chipset_tag_t sc_ic;
