hl_fw_dynami...e_fw_version(9)

💅 NAME ✨

Okay bestie, gather round — this is hl_fw_dynamic_read_device_fw_version, and it's literally right there in the Kernel API Manual (section 9, the truncated-title icon hl_fw_dynami...e_fw_version(9) herself 👑). What does she do? She reads the FW version and puts it into exposed properties. That's the whole vibe. Short, sweet, ate. 🎀

🦋 SYNOPSIS 🦋

int hl_fw_dynamic_read_device_fw_version (struct hl_device *hdev , enum
hl_fw_component fwc , const char *fw_version );

That's the signature, character for character, no notes. 💖

🌸 ARGUMENTS 🌸

• hdev — pointer to the habanalabs device structure, aka the whole main character. She's the device you're working with. 🫶
• fwc — the firmware component. Like, which firmware are we talking about here. 👀
• fw_version — the fw component's version string. The string itself, bestie. 💅

🔥 SEE ALSO 🔥

Lowkey the most important part, because this function does not exist in a vacuum, she has a whole friend group:

Ngl there's no RETURN VALUE section in this one and no OPTIONS, no env vars, no exit statuses — so don't @ me, that's the whole page. Everything above is everything she gave us. 🙈

And that's a wrap, bestie!! 🧚💜 This little gem comes to you straight out of ./drivers/accel/habanalabs/common, dated October 2026, and it was brought to you by the hl_fw_dynami...e_fw_version(9) page herself — truncation and all, and we stan a mysterious queen. 🌈⭐
