ufshcd_evaluate_tx_eqtr_fom(9)

💅 ufshcd_evaluate_tx_eqtr_fom(9) — like, the whole manual page, bestie

okay so this is a page straight out of the Kernel API Manual and it's called ufshcd_evaluate_tx_eqtr_fom(9), which lowkey sounds like a Wi-Fi password but it's actually a kernel function. stay with me, it's gonna slay ✨

---

🌸 NAME 🌸

ufshcd_evaluate_tx_eqtr_fom — literally just evaluates the TX EQTR FOM results. that's the whole vibe. no cap 💅

---

🦋 SYNOPSIS 🦋

void ufshcd_evaluate_tx_eqtr_fom (struct ufs_hba *hba , struct
       ufs_pa_layer_attr *pwr_mode , struct ufshcd_tx_eqtr_data *eqtr_data ,
       struct tx_eqtr_iter *h_iter , struct tx_eqtr_iter *d_iter );

she returns void, she takes five arguments, she's booked and busy 🎀

---

💖 ARGUMENTS 💖

• hba — your per adapter instance, the main character of the whole situation 👑
• pwr_mode — the target power mode, and yes she's carrying the gear and rate information in there, iykyk
• eqtr_data — the TX EQTR data structure, the actual goods 📦
• h_iter — the host TX EQTR iterator data structure, host side said "me first" 🖥️
• d_iter — the device TX EQTR iterator data structure, device side said "no me first" 📱

---

✨ DESCRIPTION ✨

so what she actually does: she evaluates the TX EQTR FOM results, then updates the host and device TX EQTR data accordingly — but only if the FOM have been improved compared to the previous iteration. like, she's not out here updating for no reason, she has standards 💁‍♀️ then she records the TX EQTR FOM results. iconic behavior, honestly. record it, post it, periodt 🔥

ngl the original spells it "accordingy" and honestly? we respect the typo. keeping the meaning, bestie: the update only happens when the FOM improved vs. the previous iteration. no fake glow-ups allowed 🙈

like, go read the kernel file ./drivers/ufs/core/ufs-txeq.c first, and then the whole friend group of related functions — every single one, no skipping 🫶

okay that's the whole page, you ate that 💅✨ this little gem lives in ./drivers/ufs/core, it's dated October 2026, and yes the header up top and the footer down here are both just ufshcd_evaluate_tx_eqtr_fom(9) again — she's consistent, she's committed, she's giving main character energy 🌈💖🎀
