✨ ice_check_module_power(9) ✨

okay so bestie, you clicked into the Kernel API Manual and landed on ice_check_module_power(9) — congrats, this is the whole page, and yes we're gonna read it together 🫶

---

🌸 NAME 🌸

ice_check_module_power -

(ngl the description slot after that dash is literally empty in the source, so. it's giving mysterious. iykyk 💅)

---

🦋 SYNOPSIS 🦋

void ice_check_module_power (struct ice_pf *pf , u8 link_cfg_err );

that's it. that's the whole signature. look at her go ✨

---

🎀 ARGUMENTS 🎀

• pf — a pointer to the PF struct. yes, the PF struct, the big one, she's the main character here 👑
• link_cfg_err — a bitmap, straight out of the link info structure. it's the receipts from earlier, not something you make up yourself 🧚

---

💖 DESCRIPTION 💖

so what does she actually do? she checks the module power level that came back from a previous call to aq_get_link_info, and if that module power level isn't supported, she prints error messages about it. that's the whole job. lowkey a hall monitor, highkey essential 💀

like, she's not fixing anything, she's not resetting anything, she's just looking at the value and going "babe. this is not supported" and printing the error. and honestly? someone has to. periodt 🔥

and the source file herself lives at ./drivers/net/ethernet/intel/ice 🦋 that's the directory, that's where all of this hangs out. ate. no crumbs.

real talk for one sec: if you're hunting for where this actually lives in the tree, the Kernel file is ./drivers/net/ethernet/intel/ice/ice_main.c — that's the one 🫶

that's the page bestie, you made it to the end 🎀 mwah. this was ./drivers/net/ethernet/intel/ice • October 2026 • ice_check_module_power(9) — iconic, no notes 💜
