💤 dvb_frontend_suspend(9) 💤

okay so this is a page from the Kernel API Manual bestie, and it's all about dvb_frontend_suspend — the little function that tucks your Digital TV frontend into bed 😴✨

---

🌸 NAME 🌸

dvb_frontend_suspend — Suspends a Digital TV frontend

like literally, it puts the frontend to sleep. nap time. no cap 💅

---

✨ SYNOPSIS ✨

int dvb_frontend_suspend (struct dvb_frontend *fe );

that's the whole signature, character for character, don't come for me 🫶

---

🎀 ARGUMENTS 🎀

• fe — pointer to struct dvb_frontend 💖 that's the frontend you're putting to sleep, bestie. the main character of this whole operation.

---

🦋 DESCRIPTION 🦋

so! this function prepares a Digital TV frontend to suspend. it's giving "go to bed sweetie" energy 🌙

here's the tea on the order of operations — in order to prepare the tuner to suspend, if dvb_frontend_ops.tuner_ops.suspend is available, it calls it. Otherwise, it will call dvb_frontend_ops.tuner_ops.sleep, if available. so like, suspend is the first choice, sleep is the backup plan 😌

it will also call dvb_frontend_ops.suspend to put the demod to suspend, if available. Otherwise it will call dvb_frontend_ops.sleep. same deal, different struct member 👑

real talk: the drivers should also call dvb_frontend_suspend as part of their handler for the device_driver.suspend. so like, don't forget that step or the vibe check fails fr fr 💀
