STRUCT ONFI_PARAMS(9)

💖 struct onfi_params(9) 💖

okay so this is a page from the Kernel API Manual bestie, and we're talking about struct onfi_params — literally the ONFI-specific parameters that will be reused 🫶 no cap, that's the whole vibe.

✨ NAME ✨

struct onfi_params — ONFI specific parameters that will be reused 💅

---

🌸 SYNOPSIS 🌸

struct onfi_params {
    int version;
    u16 tPROG;
    u16 tBERS;
    u16 tR;
    u16 tCCS;
    bool fast_tCAD;
    u16 sdr_timing_modes;
    u16 nvddr_timing_modes;
    u16 vendor_revision;
    u8 vendor[88];
 };

periodt. that's the struct, character for character, don't touch it 🎀

🦋 Members 🦋

okay so here's the cast of characters, main character energy one by one 👑

• version — the ONFI version, BCD encoded. and like… it's 0 if ONFI is not supported 💀 so if you see a zero, that's your sign bestie.
• tPROG — page program time ⏱️
• tBERS — block erase time 🧹
• tR — page read time 📖
• tCCS — change column setup time 🔧
• fast_tCAD — command/address/data slow or fast delay — and listen, this one is NV-DDR only ⚠️ iykyk
• sdr_timing_modes — supported asynchronous/SDR timing modes 🌈
• nvddr_timing_modes — supported source synchronous/NV-DDR timing modes ⭐
• vendor_revision — vendor specific revision number 🏷️
• vendor — vendor specific data 📦

🔥 SEE ALSO 🔥

• Kernel file ./include/linux/mtd/onfi.h — go read it, it's giving required reading 💜

not me ending the page but like… that's genuinely everything, no notes 🙈

okay so you made it to the end, slay 🎉 this was struct onfi_params(9) from ./include/linux/mtd, dated October 2026 — iconique, obsessed, see you in the next manpage bestie 💅✨🍓
