STRUCT TVEEPROM(9)

🎀 NAME 🎀

struct tveeprom — okay bestie, this is literally the struct that holds all the fields parsed out of Hauppauge eeproms 💖 it's giving "haute couture data container" and we're obsessed.

✨ SYNOPSIS ✨

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];
 };

no cap, that's the whole vibe right there 👑

🌸 Members 🌸

okay so now we go field by field, and yes I'm gonna hype each one up because they all ate 💅

• has_radio — 1 if the device has radio, 0 if it doesn't. that's it, that's the whole field, she's simple and she knows it ✨
• has_ir — lowkey the messiest one, so listen up 🫶 If has_ir == 0, then it's literally unknown what the IR capabilities are — we simply do not know, bestie. Otherwise the bits go like this:
  • bit 0) 1 (which means the 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. three whole moods 😭
• tuner_type — the type of the tuner, as TUNER_*, exactly as defined at include/media/tuner.h. iconic pointer to the truth 📍
• tuner_formats — the supported analog TV standards (V4L2_STD_*). slay, standards 🦋
• tuner_hauppauge_model — Hauppauge's code for the device model number. it's giving corporate but make it cute 💜
• tuner2_type — the type of the second tuner (TUNER_*, as defined at include/media/tuner.h). yes she has a sequel 🌈
• tuner2_formats — tuner 2's supported analog TV standards (V4L2_STD_*). twin energy fr fr ⭐
• tuner2_hauppauge_model — tuner 2's Hauppauge code for the device model number. matching set, we love to see it 🎀
• audio_processor — the analog audio decoder, as defined by enum tveeprom_audio_processor. audiophile queen 🍓
• decoder_processor — Hauppauge's code for the decoder chipset. important: it's unused by the drivers, because they probe the decoder based on the PCI or USB ID instead. so she's pretty but she's sitting this one out 💀
• model — Hauppauge's model number. the name on the birth certificate 📜
• revision — the card revision number. glow-up tracker 🌸
• serial_number — the card's serial number. everyone's favorite unique identifier 👑
• rev_str — the card revision, converted to a number. yeah, that's what it says, don't come for me 🙈
• MAC_address — the MAC address for the network interface. networking baddie behavior 💅

🦋 SEE ALSO 🦋

go read the kernel file ./include/media/tveeprom.h, plus enum tveeprom_audio_processor(9), tveeprom_hauppauge_analog(9), and tveeprom_read(9). iykyk, they're all linked in the group chat 🔥

and that's the tea, bestie 🫶 this whole page lives in ./include/media, dated October 2026, and honestly? iconic of it. mwah 💋
