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 u_short sc_open; /* reference count of open calls */ 87 88 u_char gain[SB_NDEVS][2]; /* kept in input levels */ 89#define SB_LEFT 0 90#define SB_RIGHT 1 91 92 u_int out_port; /* output port */ 93 u_int in_mask; /* input ports */ 94 u_int in_port; /* XXX needed for MI interface */ 95 u_int in_filter; /* one of SB_TREBLE_EQ, SB_BASS_EQ, 0 */ 96 97 u_int spkr_state; /* non-null is on */ 98 99 int sc_irate, sc_itc; /* Sample rate for input */ 100 int sc_orate, sc_otc; /* ...and output */ 101 102 int sc_imode; 103 int sc_omode; 104#define SB_ADAC_LS 0 105#define SB_ADAC_HS 1 106 107 u_long sc_interrupts; /* number of interrupts taken */ 108 void (*sc_intr)(void*); /* dma completion intr handler */ 109 void (*sc_mintr)(void*, int);/* midi input intr handler */ 110 void *sc_arg; /* arg for sc_intr() */ 111 112 int dmaflags; 113 caddr_t dmaaddr; 114 vm_size_t dmacnt; 115 int dmachan; /* active DMA channel */ 116 int sc_last_hs_size; /* last HS dma size */ 117 118 u_int sc_precision; /* size of samples */ 119 int sc_channels; /* # of channels */ 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_model; /* DSP model */ 127#define SBVER_MAJOR(v) (((v)>>8) & 0xff) 128#define SBVER_MINOR(v) ((v)&0xff) 129 130#define MODEL_JAZZ16 0x80000000 131 132 u_int sc_mixer_model; 133#define SBM_NONE 0 134#define SBM_CT1335 1 135#define SBM_CT1345 2 136#define SBM_CT1745 3 137}; 138 139#define ISSB2CLASS(sc) \ 140 (SBVER_MAJOR((sc)->sc_model) >= 2) 141 142#define ISSBPROCLASS(sc) \ 143 (SBVER_MAJOR((sc)->sc_model) > 2) 144 145#define ISSBPRO(sc) \ 146 (SBVER_MAJOR((sc)->sc_model) == 3) 147 148#define ISSB16CLASS(sc) \ 149 (SBVER_MAJOR((sc)->sc_model) > 3) 150 151#define ISJAZZ16(sc) \ 152 ((sc)->sc_model & MODEL_JAZZ16) 153 154 155#ifdef _KERNEL 156int sbdsp_open __P((struct sbdsp_softc *, dev_t, int)); 157void sbdsp_close __P((void *)); 158 159int sbdsp_probe __P((struct sbdsp_softc *)); 160void sbdsp_attach __P((struct sbdsp_softc *)); 161 162int sbdsp_set_in_gain __P((void *, u_int, u_char)); 163int sbdsp_set_in_gain_real __P((void *, u_int, u_char)); 164int sbdsp_get_in_gain __P((void *)); 165int sbdsp_set_out_gain __P((void *, u_int, u_char)); 166int sbdsp_set_out_gain_real __P((void *, u_int, u_char)); 167int sbdsp_get_out_gain __P((void *)); 168int sbdsp_set_monitor_gain __P((void *, u_int)); 169int sbdsp_get_monitor_gain __P((void *)); 170int sbdsp_query_encoding __P((void *, struct audio_encoding *)); 171int sbdsp_set_params __P((void *, int, struct audio_params *, struct audio_params *)); 172int sbdsp_round_blocksize __P((void *, int)); 173int sbdsp_set_out_port __P((void *, int)); 174int sbdsp_get_out_port __P((void *)); 175int sbdsp_set_in_port __P((void *, int)); 176int sbdsp_get_in_port __P((void *)); 177int sbdsp_get_avail_in_ports __P((void *)); 178int sbdsp_get_avail_out_ports __P((void *)); 179int sbdsp_speaker_ctl __P((void *, int)); 180int sbdsp_commit_settings __P((void *)); 181 182int sbdsp_dma_output __P((void *, void *, int, void (*)(void *), void*)); 183int sbdsp_dma_input __P((void *, void *, int, void (*)(void *), void*)); 184 185int sbdsp_haltdma __P((void *)); 186int sbdsp_contdma __P((void *)); 187 188void sbdsp_compress __P((int, u_char *, int)); 189void sbdsp_expand __P((int, u_char *, int)); 190 191int sbdsp_reset __P((struct sbdsp_softc *)); 192void sbdsp_spkron __P((struct sbdsp_softc *)); 193void sbdsp_spkroff __P((struct sbdsp_softc *)); 194 195int sbdsp_wdsp __P((struct sbdsp_softc *, int v)); 196int sbdsp_rdsp __P((struct sbdsp_softc *)); 197 198int sbdsp_intr __P((void *)); 199short sbversion __P((struct sbdsp_softc *)); 200 201int sbdsp_set_sr __P((struct sbdsp_softc *, u_long *, int)); 202int sbdsp_setfd __P((void *, int)); 203 204void sbdsp_mix_write __P((struct sbdsp_softc *, int, int)); 205int sbdsp_mix_read __P((struct sbdsp_softc *, int)); 206 207int sbdsp_mixer_set_port __P((void *, mixer_ctrl_t *)); 208int sbdsp_mixer_get_port __P((void *, mixer_ctrl_t *)); 209int sbdsp_mixer_query_devinfo __P((void *, mixer_devinfo_t *)); 210 211#endif 212
