2.26. Hauppauge TV EEPROM functions and data structures¶

enum tveeprom_audio_processor¶: Specifies the type of audio processor used on a Hauppauge device.

Constants

TVEEPROM_AUDPROC_NONE: No audio processor present
TVEEPROM_AUDPROC_INTERNAL: The audio processor is internal to the video processor
TVEEPROM_AUDPROC_MSP: The audio processor is a MSPXXXX device
TVEEPROM_AUDPROC_OTHER: The audio processor is another device

struct tveeprom¶: Contains the fields parsed from Hauppauge eeproms

Definition

struct tveeprom {
  u32 has_radio;
  u32 has_ir;
  u32 has_MAC_address;
  u32 tuner_type;
  u32 tuner_formats;
  u32 tuner_hauppauge_model;
  u32 tuner2_type;
  u32 tuner2_formats;
  u32 tuner2_hauppauge_model;
  u32 audio_processor;
  u32 decoder_processor;
  u32 model;
  u32 revision;
  u32 serial_number;
  char rev_str[5];
  u8 MAC_address[ETH_ALEN];
};

Members

has_radio: 1 if the device has radio; 0 otherwise.
has_ir: If has_ir == 0, then it is unknown what the IR capabilities are. Otherwise: bit 0) 1 (= IR capabilities are known); bit 1) IR receiver present; bit 2) IR transmitter (blaster) present.
has_MAC_address: 0: no MAC, 1: MAC present, 2: unknown.
tuner_type: type of the tuner (TUNER_*, as defined at include/media/tuner.h).
tuner_formats: Supported analog TV standards (V4L2_STD_*).
tuner_hauppauge_model: Hauppauge’s code for the device model number.
tuner2_type: type of the second tuner (TUNER_*, as defined at include/media/tuner.h).
tuner2_formats: Tuner 2 supported analog TV standards (V4L2_STD_*).
tuner2_hauppauge_model: tuner 2 Hauppauge’s code for the device model number.
audio_processor: analog audio decoder, as defined by enum tveeprom_audio_processor.
decoder_processor: Hauppauge’s code for the decoder chipset. Unused by the drivers, as they probe the decoder based on the PCI or USB ID.
model: Hauppauge’s model number
revision: Card revision number
serial_number: Card’s serial number
rev_str: Card revision converted to number
MAC_address: MAC address for the network interface

void tveeprom_hauppauge_analog(struct tveeprom *tvee, unsigned char *eeprom_data)¶: Fill struct tveeprom using the contents of the eeprom previously filled at eeprom_data field.

Parameters

struct tveeprom *tvee: Struct to where the eeprom parsed data will be filled;
unsigned char *eeprom_data: Array with the contents of the eeprom_data. It should contain 256 bytes filled with the contents of the eeprom read from the Hauppauge device.

int tveeprom_read(struct i2c_client *c, unsigned char *eedata, int len)¶: Reads the contents of the eeprom found at the Hauppauge devices.

Parameters

struct i2c_client *c: I2C client struct
unsigned char *eedata: Array where the eeprom content will be stored.
int len: Size of eedata array. If the eeprom content will be latter be parsed by tveeprom_hauppauge_analog(), len should be, at least, 256.
