pse_register_pw_ds(9)

💖 NAME 💖

okay so bestie, this one's called pse_register_pw_ds — and it's literally the function that registers the PSE power domains for a PSE ✨

(this whole page lives in the kernel API manual, section 9, iykyk 🧚)

---

🌸 SYNOPSIS 🌸

int pse_register_pw_ds (struct pse_controller_dev *pcdev );

like, that's the whole signature. one function, one arg, no drama 💅

---

🦋 ARGUMENTS 🦋

• pcdev — a pointer to the PSE controller device, aka the main character of this whole operation 👑

---

⭐ RETURN ⭐

0 on success, and a failure value on error — so like, check your return value, bestie, don't just vibe past it 🙈

no cap, 0 is the good ending. anything else means something went sideways, so handle it fr fr.

and that's a wrap, bestie!! this lil page came from ./drivers/net/pse-pd, dated October 2026, and it's pse_register_pw_ds(9) all the way down. go register those power domains, slay, and remember: check the return value 💖✨🎀
