STRUCT CYCX_FIRMWARE(9)

👑 struct cycx_firmware(9) — the Kernel API Manual glow-up 👑

okay bestie, so this is a page about struct cycx_firmware, from the Kernel API Manual. It's the firmware file structure for CYCX, and the whole point is that this struct is the literal blueprint of a .cfm file — like the skeleton of the firmware blob, laid out field by field. Main character energy, honestly. 🫶

✨ NAME ✨

struct cycx_firmware — the CYCX firmware file structure 💖

Here's the field-by-field breakdown, and yes we're doing all of them, no skipping:

• signature — the CFM file signature (it's the thing that says "hi, I'm a CFM file" 😌)
• version — the file format version
• checksum — the checksum over info + image
• reserved — reserved, so like… don't touch it 🙈
• descr — the description string
• info — the firmware module info
• image — the code image, and it's variable size, so it's built different

🦋 SYNOPSIS 🦋

okay so here's the actual shape of it, copy it exactly bestie, char for char:

struct cycx_firmware {
    char signature[80];
    unsigned short      version;
    unsigned short      checksum;
    unsigned short      reserved[6];
    char descr[CFM_DESCR_LEN];
    struct cycx_fw_info info;
    unsigned char       image[];
 };

signature[80]? iconic. image[] with no size in the brackets? that's a flexible array member and she is variable size, we respect her 💀✨

💅 Members 💅

So this page has a Members section and ngl, it's giving empty. There's nothing listed under it here — the actual member rundown lives up in the NAME section above, which we already did in full. No secrets hidden down here, no cap. 🎀

🎀 SEE ALSO 🎀

• Kernel file ./include/uapi/linux/cycx_cfm.h — go read the actual header bestie, it's right there 🦋
• struct cycx_fw_info(9) — her sister page, the info field's whole personality 🔥

---

fr fr, if you're poking at this struct, keep the field order and the exact types — the layout is the file format, and the file format is not gonna vibe-check itself. 💀

okay that's the whole page, mwah 💜 — this was served fresh from the source ./include/uapi/linux, dated October 2026, and the page itself answers to struct cycx_firmware(9). go slay your firmware parsing bestie, ily, bye! 🌈✨
