STRUCT DVB_TUNER_INFO(9)

💖 struct dvb_tuner_info(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're in the kernel docs today and honestly? it's giving main character energy. this whole page is about struct dvb_tuner_info, aka the lil glow-up card where your frontend writes down its name and all its min/max ranges and bandwidths. 🎀

✨ NAME ✨

struct dvb_tuner_info — Frontend name and min/max ranges/bandwidths 🦋

like, it's literally the frontend's little ID badge plus its whole flexibility range, no cap.

---

🌸 SYNOPSIS 🌸

struct dvb_tuner_info {
    char name[128];
    u32 frequency_min_hz;
    u32 frequency_max_hz;
    u32 frequency_step_hz;
    u32 bandwidth_min;
    u32 bandwidth_max;
    u32 bandwidth_step;
 };

look at her. seven fields. perfect. iconic. 💅

👑 Members 👑

• name — name of the Frontend 🫶 (it's a char name[128], so be normal about it, there's room but not infinite room)
• frequency_min_hz — minimal frequency supported in Hz. the floor, the lowercase limit, the "don't go below this" vibes 📉
• frequency_max_hz — maximum frequency supported in Hz. the ceiling, the absolute most, the top-tier limit ✨📈
• frequency_step_hz — frequency step in Hz. like how big each lil hop is when you're tuning around 👟
• bandwidth_min — minimal frontend bandwidth supported. smallest bandwidth, tiny and cute 🌸
• bandwidth_max — maximum frontend bandwidth supported. biggest bandwidth, going full send 🔥
• bandwidth_step — frontend bandwidth step. the step size between bandwidth values, the increments bestie 🎀

ngl the whole page is basically "here's my name and here's my range", which is honestly the most relatable thing a struct has ever done 🙈

okay that's the whole page, mwah 💋 — this was brought to you by the ./include/media girlies, October 2026 era, living in the Kernel API Manual, page 9, section 9, struct dvb_tuner_info(9). slay and goodbye bestie! 🧚💖⭐
