Function Documentation

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

snd_ac97_bus - create an AC97 bus component : the card instance : the bus number : the bus callbacks table : private data pointer for the new instance : the pointer to store the new AC97 bus instance.

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.

Returns zero if successful, or a negative error code on failure.

Definition at line 1915 of file ac97_codec.c.

const char* snd_ac97_get_short_name ( struct snd_ac97 * ac97 )

snd_ac97_get_short_name - retrieve codec name : the codec instance

Returns the short identifying name of the codec.

Definition at line 1841 of file ac97_codec.c.

int snd_ac97_mixer	(	struct snd_ac97_bus *	bus,
		struct snd_ac97_template *	template,
		struct snd_ac97 **	rac97
	)

snd_ac97_mixer - create an Codec97 component : the AC97 bus which codec is attached to : the template of ac97, including index, callbacks and the private data. : the pointer to store the new ac97 instance.

Creates an Codec97 component. An struct snd_ac97 instance is newly allocated and initialized from the template. The codec is then initialized by the standard procedure.

The template must include the codec number (num) and address (addr), and the private data (private_data).

The ac97 instance is registered as a low-level device, so you don't have to release it manually.

Returns zero if successful, or a negative error code on failure.

Definition at line 2011 of file ac97_codec.c.

int snd_ac97_pcm_assign	(	struct snd_ac97_bus *	bus,
		unsigned short	pcms_count,
		const struct ac97_pcm *	pcms
	)

snd_ac97_pcm_assign - assign AC97 slots to given PCM streams : the ac97 bus instance : count of PCMs to be assigned : PCMs to be assigned

It assigns available AC97 slots for given PCMs. If none or only some slots are available, pcm->xxx.slots and pcm->xxx.rslots[] members are reduced and might be zero.

int snd_ac97_pcm_close ( struct ac97_pcm * pcm )

snd_ac97_pcm_close - closes the given AC97 pcm : the ac97 pcm instance

It frees the locked AC97 slots.

int snd_ac97_pcm_double_rate_rules ( struct snd_pcm_runtime * runtime )

snd_ac97_pcm_double_rate_rules - set double rate constraints : the runtime of the ac97 front playback pcm

Installs the hardware constraint rules to prevent using double rates and more than two channels at the same time.

int snd_ac97_pcm_open	(	struct ac97_pcm *	pcm,
		unsigned int	rate,
		enum ac97_pcm_cfg	cfg,
		unsigned short	slots
	)

snd_ac97_pcm_open - opens the given AC97 pcm : the ac97 pcm instance : rate in Hz, if codec does not support VRA, this value must be 48000Hz : output stream characteristics : a subset of allocated slots (snd_ac97_pcm_assign) for this pcm

It locks the specified slots and sets the given rate to AC97 registers.

unsigned short snd_ac97_read	(	struct snd_ac97 *	ac97,
		unsigned short	reg
	)

snd_ac97_read - read a value from the given register

: the ac97 instance : the register to read

Reads a value from the given register. This will invoke the read callback directly after the register check.

Returns the read value.

Definition at line 304 of file ac97_codec.c.

int snd_ac97_set_rate	(	struct snd_ac97 *	ac97,
		int	reg,
		unsigned int	rate
	)

snd_ac97_set_rate - change the rate of the given input/output. : the ac97 instance : the register to change : the sample rate to set

Changes the rate of the given input/output on the codec. If the codec doesn't support VAR, the rate must be 48000 (except for SPDIF).

The valid registers are AC97_PMC_MIC_ADC_RATE, AC97_PCM_FRONT_DAC_RATE, AC97_PCM_LR_ADC_RATE. AC97_PCM_SURR_DAC_RATE and AC97_PCM_LFE_DAC_RATE are accepted if the codec supports them. AC97_SPDIF is accepted as a pseudo register to modify the SPDIF status bits.

Returns zero if successful, or a negative error code on failure.

int snd_ac97_tune_hardware	(	struct snd_ac97 *	ac97,
		struct ac97_quirk *	quirk,
		const char *	override
	)

snd_ac97_tune_hardware - tune up the hardware : the ac97 instance : quirk list : explicit quirk value (overrides the list if non-NULL)

Do some workaround for each pci device, such as renaming of the headphone (true line-out) control as "Master". The quirk-list must be terminated with a zero-filled entry.

Returns zero if successful, or a negative error code on failure.

Definition at line 2891 of file ac97_codec.c.

int snd_ac97_update	(	struct snd_ac97 *	ac97,
		unsigned short	reg,
		unsigned short	value
	)

snd_ac97_update - update the value on the given register : the ac97 instance : the register to change : the value to set

Compares the value with the register cache and updates the value only when the value is changed.

Returns 1 if the value is changed, 0 if no change, or a negative code on failure.

Definition at line 358 of file ac97_codec.c.

int snd_ac97_update_bits	(	struct snd_ac97 *	ac97,
		unsigned short	reg,
		unsigned short	mask,
		unsigned short	value
	)

snd_ac97_update_bits - update the bits on the given register : the ac97 instance : the register to change : the bit-mask to change : the value to set

Updates the masked-bits on the given register only when the value is changed.

Returns 1 if the bits are changed, 0 if no change, or a negative code on failure.

Definition at line 390 of file ac97_codec.c.

void snd_ac97_write	(	struct snd_ac97 *	ac97,
		unsigned short	reg,
		unsigned short	value
	)

snd_ac97_write - write a value on the given register : the ac97 instance : the register to change : the value to set

Writes a value on the given register. This will invoke the write callback directly after the register check. This function doesn't change the register cache unlike #snd_ca97_write_cache(), so use this only when you don't want to reflect the change to the suspend/resume state.

Definition at line 279 of file ac97_codec.c.

void snd_ac97_write_cache	(	struct snd_ac97 *	ac97,
		unsigned short	reg,
		unsigned short	value
	)

snd_ac97_write_cache - write a value on the given register and update the cache : the ac97 instance : the register to change : the value to set

Writes a value on the given register and updates the register cache. The cached values are used for the cached-read and the suspend/resume.
