ice_get_dest_cgu(9)

💅 ice_get_dest_cgu — Kernel API Manual, section 9, bestie

okay so real talk, this is ice_get_dest_cgu(9) from the Kernel API Manual (section 9, the kernel-functions girlies), and it's honestly a tiny little icon. Let's get into it 🎀

---

✨ NAME ✨

ice_get_dest_cgu — get destination CGU dev for given HW

like, the whole personality of this function is "which CGU do I talk to" and honestly? relatable 🌸

---

🦋 SYNOPSIS 🦋

enum ice_sbq_dev_id ice_get_dest_cgu (struct ice_hw *hw );

that's it. that's the whole vibe. returns an enum ice_sbq_dev_id, takes one arg. no cap, it's giving minimalism 💅

---

🍓 ARGUMENTS 🍓

• hw — pointer to the HW struct. yes queen, just hand her the hardware struct and she'll figure out the rest 🫶

---

💖 DESCRIPTION 💖

Get CGU client id for CGU register read/write operations.

so basically: when you're about to do CGU register reads or writes, you need to know which CGU client id to aim at — and this function is the one who tells you. she's the plug. the source of truth. the "hey bestie, it's this one" of the Intel ice driver 🔥

---

👑 RETURN 👑

CGU device id to use in SBQ transactions.

lowkey important: that's the CGU device id you plug into SBQ transactions — not just any id, the id. don't improvise, the function already handled it for you 💜

and yeah, that's the whole guest list — every last one of them, fr fr. ice_read_cgu_reg(9) and ice_write_cgu_reg(9) are literally right there at the end because obviously, that's the register read/write life this function is feeding into 😭💅

okay that's the page!! this little diva lives at ./drivers/net/ethernet/intel/ice in the Kernel API Manual (section 9), dated October 2026 — go read her neighbors, they're all icons too 🌟🎀💜
