STRUCT SE_FW_HDR(9)

✨ struct se_fw_hdr — Serial Engine firmware configuration header ✨

okay bestie, so this page is from the Kernel API Manual (that's <manpage> in fancy speak, but like… it's the Kernel API Manual, mwah 💅) and it's all about struct se_fw_hdr, aka the Serial Engine firmware configuration header. she's a header struct. she's iconic. let's get into it 🫶

🌸 NAME 🌸

struct se_fw_hdr — Serial Engine firmware configuration header 💖

---

🦋 SYNOPSIS 🦋

here's the whole shape of her, literally copy-paste this energy:

struct se_fw_hdr {
    __le32 magic;
    __le32 version;
    __le32 core_version;
    __le16 serial_protocol;
    __le16 fw_version;
    __le16 cfg_version;
    __le16 fw_size_in_items;
    __le16 fw_offset;
    __le16 cfg_size_in_items;
    __le16 cfg_idx_offset;
    __le16 cfg_val_offset;
 };

🎀 Members 🎀

bestie, let's go field by field, no skipping, we do not skip in this house 👑

• magic — set to 'SEFW'. that's the vibe check, no cap ✨
• version — the structure version number. which era of the struct are we in 💅
• core_version — QUPV3 hardware version. the actual hardware era, not the struct era 🧚
• serial_protocol — encoded in GENI_FW_REVISION. ikyky 🌈
• fw_version — firmware version, straight out of GENI_FW_REVISION 💖
• cfg_version — configuration version, from GENI_INIT_CFG_REVISION 🔥
• fw_size_in_items — the number of 32-bit words in GENI_FW_RAM. items, not bytes, don't come for me 🍓
• fw_offset — byte offset to the GENI_FW_RAM array 📍
• cfg_size_in_items — the number of GENI_FW_CFG index/value pairs 🎀
• cfg_idx_offset — byte offset to the GENI_FW_CFG index array 🦋
• cfg_val_offset — byte offset to the GENI_FW_CFG values array 💜

🧚 Description 🧚

so basically, this structure defines the SE firmware header. together with the firmware payload (her plus-one 🫶), she lives inside individual ELF segments. that's the whole deal. lowkey elegant honestly 😭
