pps_gen_register_source(9)

💖 pps_gen_register_source(9) — the Kernel API Manual glow-up ✨

okay bestie, so we're in the Kernel API Manual today and the main character is pps_gen_register_source — it's a section 9 (kernel-space, iykyk) function and honestly it's giving "tiny function, big responsibilities" 🎀

---

🌸 NAME 🌸

pps_gen_register_source — add a PPS generator into the system, no cap 💅

---

✨ SYNOPSIS ✨

struct pps_gen_device * pps_gen_register_source (const struct
       pps_gen_source_info *info );

like, yes, the line break is literally right there in the middle of the declaration. we don't question the formatting, we simply respect it 🫶

---

🦋 ARGUMENTS 🦋

• info — the PPS generator info struct (const struct pps_gen_source_info *). it's the little info packet describing the generator you're about to bring into the world 💫

---

👑 DESCRIPTION 👑

so here's the tea: this function is the one you call to register a brand-new PPS generator in the system ✨

and the slay part? when it returns successfully, the new generator is already up and running — like, not "loading", not "pending", just alive — and it can be managed by the userspace 🎀

basically you hand it the info struct and it hands you back a fully functioning generator that userspace can vibe with. iconic behaviour, honestly 💅

---

🔥 RETURN 🔥

• on success it returns the PPS generator device (a struct pps_gen_device *) — the moment, the icon, the legend 👑
• otherwise you get ERR_PTR(errno) — so check it, bestie, don't just raw-dog the pointer 😭

no cap: always IS_ERR()-check what comes back before you go dereferencing it. a successful-looking pointer is not a vibe check 💀

---

🌈 SEE ALSO 🌈

• Kernel file ./drivers/pps/generators/pps_gen.c — the source of truth, go read it 🧚
• pps_gen_unregister_source(9) — the counterpart, for when it's time to say goodbye 🦋

so yeah, that's the whole page. it lives under ./drivers/pps/generators, it's dated October 2026, and this has been your girl explaining kernel PPS registration with an unreasonable amount of enthusiasm. mwah, ily, go register some generators 💜🍓⭐
