dvb_attach(9)

💅 dvb_attach(9) — from the Kernel API Manual, bestie

okay so welcome to the glow-up era of dvb_attach, a lil kernel API manual page that's about to become your new hyperfixation. this one lives in the DVB corner of the kernel and it's giving "tiny function, big responsibilities." let's get into it 🎀

---

✨ NAME ✨

dvb_attach — the function that attaches a DVB frontend into the DVB core. that's it, that's the whole vibe. it's the matchmaker, the wingman, the "you two should meet" of the DVB world 🫶

---

🌸 SYNOPSIS 🌸

dvb_attach (FUNCTION , ARGS... );

---

🦋 ARGUMENTS 🦋

• FUNCTION — a function that lives on a frontend module and needs to be called. this is the main character of the whole operation 👑
• ARGS — the arguments you're passing to FUNCTION. yes, all of them. it's ARGS... for a reason, she takes what she takes 💅

---

🌈 DESCRIPTION 🌈

so here's the tea, bestie: this ancillary function loads a frontend module at runtime and then runs your FUNCTION function right there inside it, with your ARGS. lowkey iconic. ✨

because it bumps the symbol usage count, you must call dvb_detach at unregister time. that's not optional, that's the rule. no cap. if you skip the detach you're gonna have a bad time 😭

NOTE: 💀 ok so storytime — in the past, DVB modules (mainly frontends) were bound via the dvb_attach macro, which does an ugly hack using I2C low level functions. yeah. we don't do that anymore. such usage is deprecated and will be removed soon. instead, you should use dvb_module_probe. periodt. 🫶
