💅 ufshcd_confi..._eq_settings(9) 💅

okay so this is a page from the Kernel API Manual bestie, and the function name is lowkey so long that the header had to abbreviate it 😭 — it's giving "we ran out of room on the title line" energy. but we move! let's get into it ✨

---

🌸 NAME 🌸

ufshcd_config_tx_eq_settings — Configure TX Equalization settings 🎀

that's it, that's the vibe. it configures TX EQ settings. slay.

---

✨ SYNOPSIS ✨

int ufshcd_config_tx_eq_settings (struct ufs_hba *hba , struct
       ufs_pa_layer_attr *pwr_mode , bool force_tx_eqtr );

look at that signature, it's honestly iconic 🔥 three args, one int return, no cap.

---

🦋 ARGUMENTS 🦋

• hba — per adapter instance. like, the one adapter you're working on, your main character ✨
• pwr_mode — target power mode containing gear and rate information. it literally carries the gear + rate info, iykyk 👑
• force_tx_eqtr — execute the TX EQTR procedure. it's a bool, so it's giving "yes do the thing / no don't" 🌈

---

💖 DESCRIPTION 💖

This function finds and sets the TX Equalization settings for the given target power mode. literally that's the whole job and it ate 💅

Returns 0 on success, error code otherwise. so like, check your return value bestie, fr fr 🙈

kisses and see-you-laters, this page lives in ./drivers/ufs/core, dated October 2026, and it's still filed under ufshcd_confi..._eq_settings(9) because apparently we're still abbreviating it 💜✨
