💜 _pse_pi_delivery_power_sw_pw_ctrl(9) — a Kernel API Manual moment ✨

okay so bestie, this is a page from the Kernel API Manual, and the star of the show is _pse_pi_delivery_power_sw_pw_ctrl, which is literally the function that turns on the PSE PI when software power control is the vibe. no cap. 🫶

---

🌸 NAME 🌸

_pse_pi_delivery_power_sw_pw_ctrl — enables the PSE PI in the case of software power control. and like, it assumes the PSE lock has already been acquired, okay? don't come for her if you skipped that part 🙈

---

🎀 SYNOPSIS 🎀

int _pse_pi_delivery_power_sw_pw_ctrl (struct pse_controller_dev *pcdev
, int id , struct netlink_ext_ack *extack );

---

🦋 ARGUMENTS 🦋

• pcdev — a pointer to the PSE. your main character struct, basically 👑
• id — the index of the PSE control. it's giving "which one tho" energy
• extack — extack for error reporting. so when things go sideways, she can tell you why 💅

---

⭐ RETURN ⭐

0 on success, and a failure value on error. that's it, that's the whole mood. 🍓
