ice_aq_get_cgu_info(9)

💅 NAME 💅

ice_aq_get_cgu_info — get cgu info 🎀

okay so bestie, this is a Kernel API Manual page, section 9 of the manual pages, and it's all about one tiny little function called ice_aq_get_cgu_info whose whole entire job is... getting cgu info. that's it. that's the vibe. ✨

---

🌸 SYNOPSIS 🌸

int ice_aq_get_cgu_info (struct ice_hw *hw , u32 *cgu_id , u32
*cgu_cfg_ver , u32 *cgu_fw_ver );

like, look at her. four params, returns an int, no cap. 🫶

---

✨ ARGUMENTS ✨

• hw — pointer to the HW struct. yes the actual hardware struct, she needs to know which hardware we're talking to 💖
• cgu_id — CGU ID. the id of the cgu. iconic of her honestly
• cgu_cfg_ver — CGU config version 🎀
• cgu_fw_ver — CGU firmware version 🦋

that's the whole squad. four pointers and a dream.

---

🦋 DESCRIPTION 🦋

Get CGU info (0x0C6A) 💅

and yes, that 0x0C6A is the important part — it's the opcode, so keep it exactly like that, no reformatting, no lowercase-ing, we do not touch the hex. periodt. 🔥

---

👑 RETURN 👑

0 on success or negative value on failure. 🌈

that's it. zero means slay, negative means something went wrong and you should probably go look at why. 😭

first up, the actual source file where this lives, in the Kernel file:

./drivers/net/ethernet/intel/ice/ice_common.c

and then, bestie... the friend group. the entire friend group. every single one of these is a real reference and every single one of them ships with (9) after the name, so here they are, all of them, exactly, in order, no skipping, no summarising, i would never do that to you 💀

okay and before i go — the boring-but-mandatory lil sign-off 🎀 this page lives in the source tree at ./drivers/net/ethernet/intel/ice, it's dated October 2026, and it belongs to the Kernel API Manual, section 9, filed under ice_aq_get_cgu_info(9). mwah, go get that cgu info bestie 🫶💖
