STRUCT HELENE_CONFIG(9)

💅 struct helene_config(9) — the Kernel API Manual, but make it make sense 🎀

okay so bestie, you're looking at a page from the Kernel API Manual (section 9, the big-league kernel interface section, iykyk). Buckle up 🦋

---

✨ NAME ✨

struct helene_config — literally just the configuration of the 'Helene' tuner driver. that's the whole vibe. no cap. 💖

---

🌸 SYNOPSIS 🌸

here's the struct, copied exactly, do NOT come for me:

struct helene_config {
    u8 i2c_address;
    u8 xtal_freq_mhz;
    void *set_tuner_priv;
    int (*set_tuner_callback)(void *, int);
    enum helene_xtal xtal;
    struct dvb_frontend *fe;
 };

like... look at her. main character struct energy fr fr 👑

🫶 Members 🫶

the individual members, one by one, because every single one of them matters:

• i2c_address — the I2C address of the tuner. where you find her on the bus. that's her address, respect it 🏠
• xtal_freq_mhz — the oscillator frequency, in MHz. the heartbeat, basically 💓
• set_tuner_priv — the private context for the callback function. it's giving "plus one, but for data" 🙈
• set_tuner_callback — a callback function that notifies the parent driver which tuner is active right now. she's a gossip, she tells the parent everything 💬
• xtal — the crystal frequency, as described by enum helene_xtal. (the original page spells it "Cristal" and honestly? iconic spelling, we stan a typo 💀). anyway it's the oscillator vibe expressed as an enum ✨
• fe — the frontend that this tuner connects to. the link-up. the situationship 🔗

go read these next, bestie, no skipping:

• Kernel file ./drivers/media/dvb-frontends/helene.h

• helene_attach_s(9)

lowkey reminder: this is kernel driver territory — get the members right or nothing tunes. highkey respect the hardware 🌈

okay that's the whole page, you ate that 🍓 this masterpiece lives in ./drivers/media/dvb-frontends, brought to you by the October 2026 era of the Kernel API Manual, and it's struct helene_config(9) forever and always 💅⭐
