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 void *sc_ih; /* interrupt vectoring */ 77 78 int sc_iobase; /* I/O port base address */ 79 int sc_irq; /* interrupt */ 80 int sc_drq; /* DMA */ 81 82 u_short sc_open; /* reference count of open calls */ 83 u_short sc_adacmode; /* low/high speed mode indicator */ 84 85 u_long sc_irate; /* Sample rate for input */ 86 u_long sc_orate; /* ...and output */ 87 88 u_int gain[SB_NDEVS]; /* kept in SB levels: right/left each 89 in a nibble */ 90 91 u_int encoding; /* ulaw/linear -- keep track */ 92 93 u_int out_port; /* output port */ 94 u_int in_port; /* input port */ 95 96 u_int spkr_state; /* non-null is on */ 97 98#define SB_ADAC_LS 0 99#define SB_ADAC_HS 1 100 u_short sc_adactc; /* current adac time constant */ 101 u_long sc_interrupts; /* number of interrupts taken */ 102 void (*sc_intr)(void*); /* dma completion intr handler */ 103 void (*sc_mintr)(void*, int);/* midi input intr handler */ 104 void *sc_arg; /* arg for sc_intr() */ 105 106 int dmaflags; 107 caddr_t dmaaddr; 108 vm_size_t dmacnt; 109 int sc_last_hs_size; /* last HS dma size */ 110 int sc_chans; /* # of channels */ 111 int sc_dmadir; /* DMA direction */ 112#define SBP_DMA_NONE 0 113#define SBP_DMA_IN 1 114#define SBP_DMA_OUT 2 115 116 u_int sc_model; /* DSP model */ 117#define SBVER_MAJOR(v) ((v)>>8) 118#define SBVER_MINOR(v) ((v)&0xff) 119}; 120 121#define ISSBPRO(sc) \ 122 (SBVER_MAJOR((sc)->sc_model) == 3) 123 124#define ISSBPROCLASS(sc) \ 125 (SBVER_MAJOR((sc)->sc_model) > 2) 126 127#define ISSB16CLASS(sc) \ 128 (SBVER_MAJOR((sc)->sc_model) > 3) 129 130 131#ifdef _KERNEL 132int sbdsp_open __P((struct sbdsp_softc *, dev_t, int)); 133void sbdsp_close __P((void *)); 134 135int sbdsp_probe __P((struct sbdsp_softc *)); 136void sbdsp_attach __P((struct sbdsp_softc *)); 137 138int sbdsp_set_in_gain __P((void *, u_int, u_char)); 139int sbdsp_set_in_gain_real __P((void *, u_int, u_char)); 140int sbdsp_get_in_gain __P((void *)); 141int sbdsp_set_out_gain __P((void *, u_int, u_char)); 142int sbdsp_set_out_gain_real __P((void *, u_int, u_char)); 143int sbdsp_get_out_gain __P((void *)); 144int sbdsp_set_monitor_gain __P((void *, u_int)); 145int sbdsp_get_monitor_gain __P((void *)); 146int sbdsp_set_in_sr __P((void *, u_long)); 147int sbdsp_set_in_sr_real __P((void *, u_long)); 148u_long sbdsp_get_in_sr __P((void *)); 149int sbdsp_set_out_sr __P((void *, u_long)); 150int sbdsp_set_out_sr_real __P((void *, u_long)); 151u_long sbdsp_get_out_sr __P((void *)); 152int sbdsp_query_encoding __P((void *, struct audio_encoding *)); 153int sbdsp_set_encoding __P((void *, u_int)); 154int sbdsp_get_encoding __P((void *)); 155int sbdsp_set_precision __P((void *, u_int)); 156int sbdsp_get_precision __P((void *)); 157int sbdsp_set_channels __P((void *, int)); 158int sbdsp_get_channels __P((void *)); 159int sbdsp_round_blocksize __P((void *, int)); 160int sbdsp_set_out_port __P((void *, int)); 161int sbdsp_get_out_port __P((void *)); 162int sbdsp_set_in_port __P((void *, int)); 163int sbdsp_get_in_port __P((void *)); 164int sbdsp_get_avail_in_ports __P((void *)); 165int sbdsp_get_avail_out_ports __P((void *)); 166int sbdsp_speaker_ctl __P((void *, int)); 167int sbdsp_commit_settings __P((void *)); 168 169int sbdsp_dma_output __P((void *, void *, int, void (*)(), void*)); 170int sbdsp_dma_input __P((void *, void *, int, void (*)(), void*)); 171 172int sbdsp_haltdma __P((void *)); 173int sbdsp_contdma __P((void *)); 174 175u_int sbdsp_get_silence __P((int)); 176void sbdsp_compress __P((int, u_char *, int)); 177void sbdsp_expand __P((int, u_char *, int)); 178 179int sbdsp_reset __P((struct sbdsp_softc *)); 180void sbdsp_spkron __P((struct sbdsp_softc *)); 181void sbdsp_spkroff __P((struct sbdsp_softc *)); 182 183int sbdsp_wdsp(int iobase, int v); 184int sbdsp_rdsp(int iobase); 185 186int sbdsp_intr __P((void *)); 187short sbversion __P((struct sbdsp_softc *)); 188 189int sbdsp_set_sr __P((struct sbdsp_softc *, u_long *, int)); 190int sbdsp_setfd __P((void *, int)); 191 192void sbdsp_mix_write __P((struct sbdsp_softc *, int, int)); 193int sbdsp_mix_read __P((struct sbdsp_softc *, int)); 194 195int sbdsp_mixer_set_port __P((void *, mixer_ctrl_t *)); 196int sbdsp_mixer_get_port __P((void *, mixer_ctrl_t *)); 197int sbdsp_mixer_query_devinfo __P((void *, mixer_devinfo_t *)); 198 199#endif 200
