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 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_locked; /* true when doing HS DMA */ 84 u_short sc_adacmode; /* low/high speed mode indicator */ 85 86 u_long sc_irate; /* Sample rate for input */ 87 u_long sc_orate; /* ...and output */ 88 89 u_int gain[SB_NDEVS]; /* kept in SB levels: right/left each 90 in a nibble */ 91 92 u_int encoding; /* ulaw/linear -- keep track */ 93 94 u_int out_port; /* output port */ 95 u_int in_port; /* input port */ 96 97 u_int spkr_state; /* non-null is on */ 98 99 #define SB_ADAC_LS 0 100 #define SB_ADAC_HS 1 101 u_short sc_adactc; /* current adac time constant */ 102 u_long sc_interrupts; /* number of interrupts taken */ 103 void (*sc_intr)(void*); /* dma completion intr handler */ 104 void (*sc_mintr)(void*, int);/* midi input intr handler */ 105 void *sc_arg; /* arg for sc_intr() */ 106 107 int dmaflags; 108 caddr_t dmaaddr; 109 vm_size_t dmacnt; 110 int sc_last_hsw_size; /* last HS dma size */ 111 int sc_last_hsr_size; /* last HS dma size */ 112 int sc_chans; /* # of channels */ 113 char sc_dmain_inprogress; /* DMA input in progress? */ 114 char sc_dmaout_inprogress; /* DMA output in progress? */ 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 132 int sbdsp_open __P((struct sbdsp_softc *, dev_t, int)); 133 void sbdsp_close __P((void *)); 134 135 int sbdsp_probe __P((struct sbdsp_softc *)); 136 void sbdsp_attach __P((struct sbdsp_softc *)); 137 138 int sbdsp_set_in_gain __P((void *, u_int, u_char)); 139 int sbdsp_set_in_gain_real __P((void *, u_int, u_char)); 140 int sbdsp_get_in_gain __P((void *)); 141 int sbdsp_set_out_gain __P((void *, u_int, u_char)); 142 int sbdsp_set_out_gain_real __P((void *, u_int, u_char)); 143 int sbdsp_get_out_gain __P((void *)); 144 int sbdsp_set_monitor_gain __P((void *, u_int)); 145 int sbdsp_get_monitor_gain __P((void *)); 146 int sbdsp_set_in_sr __P((void *, u_long)); 147 int sbdsp_set_in_sr_real __P((void *, u_long)); 148 u_long sbdsp_get_in_sr __P((void *)); 149 int sbdsp_set_out_sr __P((void *, u_long)); 150 int sbdsp_set_out_sr_real __P((void *, u_long)); 151 u_long sbdsp_get_out_sr __P((void *)); 152 int sbdsp_query_encoding __P((void *, struct audio_encoding *)); 153 int sbdsp_set_encoding __P((void *, u_int)); 154 int sbdsp_get_encoding __P((void *)); 155 int sbdsp_set_precision __P((void *, u_int)); 156 int sbdsp_get_precision __P((void *)); 157 int sbdsp_set_channels __P((void *, int)); 158 int sbdsp_get_channels __P((void *)); 159 int sbdsp_round_blocksize __P((void *, int)); 160 int sbdsp_set_out_port __P((void *, int)); 161 int sbdsp_get_out_port __P((void *)); 162 int sbdsp_set_in_port __P((void *, int)); 163 int sbdsp_get_in_port __P((void *)); 164 int sbdsp_get_avail_in_ports __P((void *)); 165 int sbdsp_get_avail_out_ports __P((void *)); 166 int sbdsp_speaker_ctl __P((void *, int)); 167 int sbdsp_commit_settings __P((void *)); 168 169 int sbdsp_dma_output __P((void *, void *, int, void (*)(), void*)); 170 int sbdsp_dma_input __P((void *, void *, int, void (*)(), void*)); 171 172 int sbdsp_haltdma __P((void *)); 173 int sbdsp_contdma __P((void *)); 174 175 u_int sbdsp_get_silence __P((int)); 176 void sbdsp_compress __P((int, u_char *, int)); 177 void sbdsp_expand __P((int, u_char *, int)); 178 179 int sbdsp_reset __P((struct sbdsp_softc *)); 180 void sbdsp_spkron __P((struct sbdsp_softc *)); 181 void sbdsp_spkroff __P((struct sbdsp_softc *)); 182 183 int sbdsp_wdsp(int iobase, int v); 184 int sbdsp_rdsp(int iobase); 185 186 int sbdsp_intr __P((void *)); 187 short sbversion __P((struct sbdsp_softc *)); 188 189 int sbdsp_set_sr __P((struct sbdsp_softc *, u_long *, int)); 190 int sbdsp_setfd __P((void *, int)); 191 192 void sbdsp_mix_write __P((struct sbdsp_softc *, int, int)); 193 int sbdsp_mix_read __P((struct sbdsp_softc *, int)); 194 195 int sbdsp_mixer_set_port __P((void *, mixer_ctrl_t *)); 196 int sbdsp_mixer_get_port __P((void *, mixer_ctrl_t *)); 197 int sbdsp_mixer_query_devinfo __P((void *, mixer_devinfo_t *)); 198 199 #endif 200
