hl_fw_dynam...e_descriptor(9)

💖 hl_fw_dynamic_validate_descriptor — NAME era ✨

okay bestie, welcome to the Kernel API Manual 🎀 — we're doing a full vibe check on hl_fw_dynamic_validate_descriptor, aka the little function whose whole personality is "validate FW descriptor" 💅

---

🌸 SYNOPSIS 🌸

int hl_fw_dynamic_validate_descriptor (struct hl_device *hdev , struct
fw_load_mgr *fw_loader , struct lkd_fw_comms_desc *fw_desc );

literally three args, one int coming back, no drama 🦋

---

✨ ARGUMENTS ✨

• hdev — pointer to the habanalabs device structure 👑 like, this is the device's whole main character record
• fw_loader — managing structure for loading device's FW 🧚 the girlboss in charge of getting the firmware loaded
• fw_desc — the descriptor from FW 💌 the actual thing FW handed over that we're about to peer at

---

🫶 DESCRIPTION 🫶

return 0 on success, otherwise non-zero error code 😭💀 that's the whole plot — zero means slay, anything else means something went sideways and you get a non-zero error code back. periodt.
