ufshcd_update_tx_eq_settings_attrs(9)

okay bestie, welcome to the Kernel API Manual entry for ufshcd_update_tx_eq_settings_attrs — yes, that long iconic function name ate and left no crumbs 💅✨.

✨ NAME ✨

ufshcd_update_tx_eq_settings_attrs — update TX EQ settings in UFS attributes. That's literally the whole name, no cap 🎀.

🌸 SYNOPSIS 🌸

void ufshcd_update_tx_eq_settings_attrs (struct ufs_hba *hba , u8 gear );

🦋 ARGUMENTS 🦋

• hba — per adapter instance 🫶.
• gear — target gear ⭐.

💖 DESCRIPTION 💖

okay so this function is the little record-keeper of the UFS world 🎀. It stores the optimal TX Equalization settings obtained from the TX EQTR procedure into UFS device attributes for future fast-path retrieval. The settings are stored in two complementary attributes:

1. qTxEQGnSettings (64-bit): main attribute containing PreShoot and DeEmphasis values for both host and device TX lanes 🔥.
2. wTxEQGnSettingsExt (16-bit): extended attribute containing PreCoding enable flags and validity indicator 🌈.
