ENUM HL_FW_TYPES(9)

💅 enum hl_fw_types(9) — Kernel API Manual energy, but make it make sense

okay bestie, so this one is a page from the Kernel API Manual, and it's literally just a little enum that tells you which firmware types can be chillin' in your system. No cap, that's the whole vibe. It lives next to ./drivers/accel/habanalabs/common/habanalabs.h, and if you're the kind of girlie who reads kernel headers for fun (me, I'm her), this is your moment ✨

---

🌸 NAME 🌸

enum hl_fw_types — literally the F/W types that are present in the system 🫶

---

✨ SYNOPSIS ✨

enum hl_fw_types {
    FW_TYPE_NONE ,
    FW_TYPE_LINUX ,
    FW_TYPE_BOOT_CPU ,
    FW_TYPE_PREBOOT_CPU ,
    FW_TYPE_ALL_TYPES

};

that's it. that's the enum. she's small but she's doing her job 💅

---

🎀 Constants 🎀

okay so here's the whole cast, one by one, no skipping, we don't do that here:

• FW_TYPE_NONE — the "no FW component indication" girlie. she's giving nothing and honestly that's her whole point 🙈
• FW_TYPE_LINUX — the Linux image for the device CPU. yes, actual Linux, running over there, doing Linux things 🐧
• FW_TYPE_BOOT_CPU — the Boot image for the device CPU. it boots. that's the assignment and she ate 🔥
• FW_TYPE_PREBOOT_CPU — this one means pre-loaded CPUs are present in the system (preboot, ppboot etc...). okay so the "etc..." is doing a lot of heavy lifting there, but we respect it 💜
• FW_TYPE_ALL_TYPES — the Mask for all types. she contains multitudes. main character energy fr fr 👑

bestie. sit down. hydrate. this list is long and we are not skipping a single one, because every single one of these deserves her moment in the group chat. here we go, in the exact order the manpage gave them, all under Kernel file ./drivers/accel/habanalabs/common/habanalabs.h:

like I said. long. but we got through it together and that's what matters 💖 and yeah, the whole list is still under ./drivers/accel/habanalabs/common — the directory, not the header, the header is the habanalabs.h bit above. iykyk 🧚

no cap, that's genuinely every reference — if you need the actual behaviour of any of these, go read their pages, because this one is only about the firmware types. periodt 💅

okay that's the whole vibe check, bestie — this page is from the ./drivers/accel/habanalabs/common source tree, dated October 2026, and honestly? iconic. go forth and know your FW types 👑🦋💜
