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 */ 73struct sbdsp_softc { 74 struct device sc_dev; /* base device */ 75 struct isadev sc_id; /* ISA device */ 76 isa_chipset_tag_t sc_ic; 77 bus_space_tag_t sc_iot; /* tag */ 78 bus_space_handle_t sc_ioh; /* handle */ 79 void *sc_ih; /* interrupt vectoring */ 80 81 int sc_iobase; /* I/O port base address */ 82 int sc_irq; /* interrupt */ 83 int sc_drq8; /* DMA (8-bit) */ 84 int sc_drq16; /* DMA (16-bit) */ 85 86 struct device *sc_isa; /* pointer to ISA parent */ 87 88 u_short sc_open; /* reference count of open calls */ 89 90 u_char gain[SB_NDEVS][2]; /* kept in input levels */ 91#define SB_LEFT 0 92#define SB_RIGHT 1 93 94 u_int out_port; /* output port */ 95 u_int in_mask; /* input ports */ 96 u_int in_port; /* XXX needed for MI interface */ 97 u_int in_filter; /* one of SB_TREBLE_EQ, SB_BASS_EQ, 0 */ 98 99 u_int spkr_state; /* non-null is on */ 100 101 u_int sc_irate; /* Sample rate for input */ 102 u_int sc_orate; /* ...and output */ 103 u_char sc_itc; 104 u_char sc_otc; 105 106 struct sbmode *sc_imodep; 107 struct sbmode *sc_omodep; 108 u_char sc_ibmode; 109 u_char sc_obmode; 110 111 u_long sc_interrupts; /* number of interrupts taken */ 112 void (*sc_intr)(void*); /* dma completion intr handler */ 113 void (*sc_mintr)(void*, int);/* midi input intr handler */ 114 void *sc_arg; /* arg for sc_intr() */ 115 116 int dmaflags; 117 caddr_t dmaaddr; 118 vm_size_t dmacnt; 119 int dmachan; /* active DMA channel */ 120 121 int sc_dmadir; /* DMA direction */ 122#define SB_DMA_NONE 0 123#define SB_DMA_IN 1 124#define SB_DMA_OUT 2 125 126 u_int sc_mixer_model; 127#define SBM_NONE 0 128#define SBM_CT1335 1 129#define SBM_CT1345 2 130#define SBM_CT1745 3 131 132 u_int sc_model; /* DSP model */ 133#define SB_UNK -1 134#define SB_1 0 /* original SB */ 135#define SB_20 1 /* SB 2 */ 136#define SB_2x 2 /* SB 2, new version */ 137#define SB_PRO 3 /* SB Pro */ 138#define SB_JAZZ 4 /* Jazz 16 */ 139#define SB_16 5 /* SB 16 */ 140 141 u_int sc_version; /* DSP version */ 142#define SBVER_MAJOR(v) (((v)>>8) & 0xff) 143#define SBVER_MINOR(v) ((v)&0xff) 144}; 145 146#define ISSBPRO(sc) ((sc)->sc_model == SB_PRO || (sc)->sc_model == SB_JAZZ) 147#define ISSBPROCLASS(sc) ((sc)->sc_model >= SB_PRO) 148#define ISSB16CLASS(sc) ((sc)->sc_model == SB_16) 149 150#ifdef _KERNEL 151int sbdsp_open __P((struct sbdsp_softc *, dev_t, int)); 152void sbdsp_close __P((void *)); 153 154int sbdsp_probe __P((struct sbdsp_softc *)); 155void sbdsp_attach __P((struct sbdsp_softc *)); 156 157int sbdsp_set_in_gain __P((void *, u_int, u_char)); 158int sbdsp_set_in_gain_real __P((void *, u_int, u_char)); 159int sbdsp_get_in_gain __P((void *)); 160int sbdsp_set_out_gain __P((void *, u_int, u_char)); 161int sbdsp_set_out_gain_real __P((void *, u_int, u_char)); 162int sbdsp_get_out_gain __P((void *)); 163int sbdsp_set_monitor_gain __P((void *, u_int)); 164int sbdsp_get_monitor_gain __P((void *)); 165int sbdsp_query_encoding __P((void *, struct audio_encoding *)); 166int sbdsp_set_params __P((void *, int, struct audio_params *, struct audio_params *)); 167int sbdsp_round_blocksize __P((void *, int)); 168int sbdsp_set_out_port __P((void *, int)); 169int sbdsp_get_out_port __P((void *)); 170int sbdsp_set_in_port __P((void *, int)); 171int sbdsp_get_in_port __P((void *)); 172int sbdsp_get_avail_in_ports __P((void *)); 173int sbdsp_get_avail_out_ports __P((void *)); 174int sbdsp_speaker_ctl __P((void *, int)); 175int sbdsp_commit_settings __P((void *)); 176 177int sbdsp_dma_init_input __P((void *, void *, int)); 178int sbdsp_dma_init_output __P((void *, void *, int)); 179int sbdsp_dma_output __P((void *, void *, int, void (*)(void *), void*)); 180int sbdsp_dma_input __P((void *, void *, int, void (*)(void *), void*)); 181 182int sbdsp_haltdma __P((void *)); 183int sbdsp_contdma __P((void *)); 184 185void sbdsp_compress __P((int, u_char *, int)); 186void sbdsp_expand __P((int, u_char *, int)); 187 188int sbdsp_reset __P((struct sbdsp_softc *)); 189void sbdsp_spkron __P((struct sbdsp_softc *)); 190void sbdsp_spkroff __P((struct sbdsp_softc *)); 191 192int sbdsp_wdsp __P((struct sbdsp_softc *, int v)); 193int sbdsp_rdsp __P((struct sbdsp_softc *)); 194 195int sbdsp_intr __P((void *)); 196 197int sbdsp_set_sr __P((struct sbdsp_softc *, u_long *, int)); 198int sbdsp_setfd __P((void *, int)); 199 200void sbdsp_mix_write __P((struct sbdsp_softc *, int, int)); 201int sbdsp_mix_read __P((struct sbdsp_softc *, int)); 202 203int sbdsp_mixer_set_port __P((void *, mixer_ctrl_t *)); 204int sbdsp_mixer_get_port __P((void *, mixer_ctrl_t *)); 205int sbdsp_mixer_query_devinfo __P((void *, mixer_devinfo_t *)); 206 207void *sb_malloc __P((void *, unsigned long, int, int)); 208void sb_free __P((void *, void *, int)); 209unsigned long sb_round __P((void *, unsigned long)); 210 211 212#endif 213
