STRUCT HL_COMPONENT_VERSIONS(9)

💖 struct hl_component_versions — Kernel API Manual, but make it cute

okay so bestie, pull up a chair 🎀 this is the 9th section of the manual (kernel API vibes) and it's literally just one struct, but she's an iconic struct, so let's get into it.

✨ NAME ✨

struct hl_component_versions — the versions associated with an hl component. that's it, that's the whole name. short, sweet, slay 💅

🌸 SYNOPSIS 🌸

struct hl_component_versions {
    __le16 struct_size;
    __le16 modules_offset;
    __u8 component[VERSION_MAX_LEN];
    __u8 fw_os[VERSION_MAX_LEN];
    __u8 comp_name[NAME_MAX_LEN];
    __u8 modules_counter;
    __u8 reserved[3];
    struct hl_module_data modules[];
};

look at her. all fields, no notes. copy it exactly if you're typing it out, bestie — no "fixing" the names, i'm watching 👀

🦋 Members 🦋

• struct_size — the size of all the struct ✨ and yes, that includes the dynamic size of modules. she's not just the fixed part, she's the whole package 💖
• modules_offset — where the modules field sits inside this struct, as an offset. so you know exactly where to find her 🧚
• component — the version of the component itself. main character energy, honestly 👑
• fw_os — the Firmware OS Version. firmware but make it fashion 💅
• comp_name — the name of the component. hi, what's your name, what's your sign 🌈
• modules_counter — the number of set bits in modules_mask. count 'em, bestie 🔥
• reserved — reserved for future use. she's saving space for later, we respect the hustle 🙈
• modules — the versions of the component's modules 🍓 the elaborated explanation lives over in struct cpucp_versions, so go read that one if you want the full lore, iykyk

• Kernel file ./include/linux/habanalabs/hl_boot_if.h — go read the source, it's giving ✨

ngl, this whole page is basically a love letter to one header file. no cap, if you're touching habanalabs boot stuff, that's your girl 🫶

and that's the tea 💜 this beauty lives in ./include/linux/habanalabs, dated October 2026, and she's filed under struct hl_component_versions(9) in the Kernel API Manual. mwah, go forth and version responsibly 😭💖
