STRUCT PANTHOR_FW_BINARY_HDR(9)

💖 struct panthor_fw_binary_hdr(9) — Kernel API Manual, bestie edition 💖

okay so this page is from the Kernel API Manual, and it's literally all about struct panthor_fw_binary_hdr — the firmware binary header. iconic little struct, honestly. let's get into it 🫶

---

✨ NAME ✨

struct panthor_fw_binary_hdr — the Firmware binary header. that's it, that's the vibe. 🎀

---

🌸 SYNOPSIS 🌸

the whole struct, laid out exactly, no cap:

struct panthor_fw_binary_hdr {
    u32 magic;
  #define CSF_FW_BINARY_HEADER_MAGIC              0xc3f13a6e;
    u8 minor;
    u8 major;
  #define CSF_FW_BINARY_HEADER_MAJOR_MAX          0;
    u16 padding1;
    u32 version_hash;
    u32 padding2;
    u32 size;
 };

like… it's giving "small struct, big responsibilities" and i'm obsessed 💅

🧚 Members 🧚

• magic — the magic value you check to make sure the binary is actually valid. it's the vibe check of the whole struct, fr fr. ⭐
• minor — the Minor FW version. the lil one. 🍓
• major — the Major FW version. the main character energy one. 👑
• padding1 — MBZ. (that's "must be zero", bestie — keep it clean 💜)
• version_hash — the FW version hash. 🔥
• padding2 — MBZ again. same rules. 🙈
• size — the FW binary size. how big is the whole thing? this tells you. 🌈

lowkey important: padding1 and padding2 are both marked MBZ, so don't be putting random stuff in there, okay? 💀
