STRUCT UFSHCD_TX_EQTR_RECORD(9)

💖 struct ufshcd_tx_eqtr_record(9) — Kernel API Manual 💖

okay bestie, welcome to the Kernel API Manual page for struct ufshcd_tx_eqtr_record(9). This is the TX Equalization Training record, and it is literally right here for you. 🦋

🌸 NAME 🌸

struct ufshcd_tx_eqtr_record — TX Equalization Training record. That's the name, that's the vibe, periodt. ✨

✨ SYNOPSIS ✨

okay so the struct is giving exactly this, no edits, no cap:

struct ufshcd_tx_eqtr_record {
    u8 host_fom[UFS_MAX_LANES][TX_HS_NUM_PRESHOOT][TX_HS_NUM_DEEMPHASIS];
    u8 device_fom[UFS_MAX_LANES][TX_HS_NUM_PRESHOOT][TX_HS_NUM_DEEMPHASIS];
    ktime_t last_record_ts;
    u16 last_record_index;
    u16 saved_adapt_eqtr;
};

🫶 Members 🫶

• host_fom — the Host TX EQTR FOM record. That's the host-side entry, bestie.
• device_fom — the Device TX EQTR FOM record. Matching energy, device side.
• last_record_ts — Timestamp of the most recent TX EQTR record. It's a ktime_t, so it's timestamping properly.
• last_record_index — Index of the most recent TX EQTR record. A lil u16 index moment.
• saved_adapt_eqtr — Saved Adaptation length setting for TX EQTR. A u16 keeping that saved setting safe.
