struct hpi_control_cache* hpi_alloc_control_cache ( const u32  control_count, const u32  size_in_bytes, u8 *  p_dsp_control_buffer  )

read

Allocate control cache.

Returns

Cache pointer, or NULL if allocation fails.

short hpi_check_control_cache	(	struct hpi_control_cache *	p_cache,
		struct hpi_message *	phm,
		struct hpi_response *	phr
	)

CheckControlCache checks the cache and fills the struct hpi_response accordingly. It returns one if a cache hit occurred, zero otherwise.

void hpi_cmn_control_cache_sync_to_msg	(	struct hpi_control_cache *	p_cache,
		struct hpi_message *	phm,
		struct hpi_response *	phr
	)

Updates the cache with Set values.

Only update if no error. Volume and Level return the limited values in the response, so use these Multiplexer does so use sent values

Definition at line 105 of file hpicmn.c.

struct hpi_adapter_obj* hpi_find_adapter ( u16  adapter_index )

read

FindAdapter returns a pointer to the struct hpi_adapter_obj with index wAdapterIndex in an HPI_ADAPTERS_LIST structure.

Definition at line 653 of file hpicmn.c.

u16 hpi_validate_response	(	struct hpi_message *	phm,
		struct hpi_response *	phr
	)

Given an HPI Message that was sent out and a response that was received, validate that the response has the correct fields filled in, i.e ObjectType, Function etc
