tuner_status(9)

💅 tuner_status(9)

okay so first things first, bestie: this is tuner_status, and it lives in the Kernel API Manual — yes, that's the manual we're in, we're literally inside it rn. 🫶

---

✨ NAME ✨

tuner_status — dumps the current tuner status at dmesg

like, it just spills the tea straight into your kernel log. iconic behavior honestly. 🎀

---

🦋 SYNOPSIS 🦋

void tuner_status (struct dvb_frontend *fe );

---

🌸 ARGUMENTS 🌸

• fe — pointer to struct dvb_frontend. that's it, that's the whole argument list. one (1) pointer. she's lowkey minimal and I respect it. 💜

---

👑 DESCRIPTION 👑

so here's the vibe check: this callback is only for driver debug purposes. literally nothing else. it exists to answer to VIDIOC_LOG_STATUS, which is the ioctl that goes "hey bestie, what's the tuner doing rn?" and this function answers by dumping stuff into dmesg.

⚠️ and listen — no changes should happen on this call. it's a read-only gossip session, not a makeover. no state gets touched, no configs get rearranged, nothing moves. it looks and it tells. periodt. 💀
