SND_AC97_BUS(9)                         Control/Mixer API                         SND_AC97_BUS(9)



NAME
       snd_ac97_bus - create an AC97 bus component

SYNOPSIS
       int snd_ac97_bus(struct snd_card * card, int num, struct snd_ac97_bus_ops * ops,
                        void * private_data, struct snd_ac97_bus ** rbus);

ARGUMENTS
       card
           the card instance

       num
           the bus number

       ops
           the bus callbacks table

       private_data
           private data pointer for the new instance

       rbus
           the pointer to store the new AC97 bus instance.

DESCRIPTION
       Creates an AC97 bus component. An struct snd_ac97_bus instance is newly allocated and
       initialized.

       The ops table must include valid callbacks (at least read and write). The other callbacks,
       wait and reset, are not mandatory.

       The clock is set to 48000. If another clock is needed, set (*rbus)->clock manually.

       The AC97 bus instance is registered as a low-level device, so you don't have to release it
       manually.

RETURN
       Zero if successful, or a negative error code on failure.
