💖 dvb_frontend_resume(9) 💖

okay so bestie, welcome to the kernel API manual section 9, where we talk about <pink>dvb_frontend_resume</pink> — the little function that wakes your Digital TV frontend back up after a lil nap 😴➡️✨ No cap, it's giving "rise and shine bestie, we're retuning."

---

✨ NAME ✨

dvb_frontend_resume — resumes a Digital TV frontend 🫶 she's back and she's slaying.

---

🌸 SYNOPSIS 🌸

int dvb_frontend_resume (struct dvb_frontend *fe );

---

🎀 ARGUMENTS 🎀

• fe — a pointer to struct dvb_frontend 💅 that's it, that's the argument, one (1) whole pointer, iconic.

---

🦋 DESCRIPTION 🦋

so the whole vibe of this function is: resume the usual operation of the tuner after resume. like, the tuner was asleep, now it's awake, we love that for it 💖

To actually do the resume thing, it calls the demod's dvb_frontend_ops.resume if available. Otherwise? It calls dvb_frontend_ops.init instead. two paths, same goal, we love a fallback 😌

Then, if dvb_frontend_ops.tuner_ops.resume is available, it calls it. Otherwise, it will call dvb_frontend_ops.tuner_ops.init, if available. (yeah the original says "It, it calls it" and "Otherwise,t will call" — the function is valid even if the manpage had a little typo moment 💀 we still ate, fr fr.)

Once tuner and demods are resumed, she gets very serious about one thing: it will enforce that the SEC voltage and tone are restored to their previous values 🔥 and then it wakes up the frontend's kthread so it can retune the frontend ⭐ like a little alarm clock for hardware.

💡 extra note for the driver girlies: drivers should also call dvb_frontend_resume as part of their handler for the device_driver.resume. don't leave it out, bestie, that's the whole point 🙈
