pse_pi_allocate_pw_budget(9)

✨ NAME ✨

pse_pi_allocate_pw_budget — allocate power budget for the PI. Okay bestie, this is the pse_pi_allocate_pw_budget(9) page from the Kernel API Manual, and we're gonna get through it together. 💖

🛠️ SYNOPSIS 🛠️

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

🎀 ARGUMENTS 🎀

okay so here's the cast, bestie:

• pcdev — a pointer to the PSE. It's giving main-character pointer energy. 👑
• id — index of the PSE control. Literally the ID. 🔢
• pw_req — power requested in mW. Keep that unit exactly as written, no cap. ⚡
• extack — extack for error reporting. It's the little messenger for when stuff goes sideways. 🫶

🔁 RETURN 🔁

0 on success and failure value on error. That's the whole vibe check: 0 when it's slaying, failure value when it's not. 💀
