It accomplishes its goal by * direct IO at the moment. * o Different programs should be able to open the device * with O_RDONLY and O_WRONLY at the same time. But I * do not see support for this in /sys/dev/audio.c, so * I cannot effectively code it. * o We should nicely deal with the cards that can do mulaw * and alaw output. * o Rework the mixer interface. * o Deal with the lvls better. We need to do better mapping * between logarithmic scales and the one byte that * we are passed. * o Deal better with cards that have no mixer. */ #include "aria.h" #if NARIA > 0 #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #define FREAD 1 #define FWRITE 2 #ifdef AUDIO_DEBUG #define DPRINTF(x) printf x int ariadebug = 0; #else #define DPRINTF(x) #endif struct aria_mixdev_info { u_char num_channels; u_char level[2]; u_char mute; }; struct aria_mixmaster { u_char num_channels; u_char level[2]; u_char treble[2]; u_char bass[2]; }; struct aria_softc { struct device sc_dev; /* base device */ void *sc_ih; /* interrupt vectoring */ bus_space_tag_t sc_iot; /* Tag on 'da bus. */ bus_space_handle_t sc_ioh; /* Handle of iospace */ isa_chipset_tag_t sc_ic; /* ISA chipset info */ u_short sc_open; /* reference count of open calls */ u_short sc_play; /* non-paused play chans 2**chan */ u_short sc_record; /* non-paused record chans 2**chan */ /* XXX -- keep this?
