hl_fw_dynamic_copy_msg(9)

✨ hl_fw_dynamic_copy_msg — Kernel API Manual ✨

okay so real talk bestie, we're in the Kernel API Manual today and this is legit one of those tiny-but-load-bearing functions, iykyk 🎀

🌸 NAME 🌸

hl_fw_dynamic_copy_msg — copies a msg into memory that was allocated by the FW 💅

✨ SYNOPSIS ✨

int hl_fw_dynamic_copy_msg (struct hl_device *hdev , struct
lkd_msg_comms *msg , struct fw_load_mgr *fw_loader );

it's giving "returns an int, takes three things" — that's the whole syllabus 🦋

💖 ARGUMENTS 💖

three besties walk into a function:

• hdev — pointer to the habanalabs device structure. your main character device struct, the one everything else is orbiting 🌈
• msg — the message. that's it, that's the whole description, she's literally just the message 💀
• fw_loader — the managing structure for loading the device's FW. the girlboss in charge of the firmware-loading situation 👑

🔥 SEE ALSO 🔥

okay buckle up because this list is LONG and every single one of these is a real function, no cap. she has so many mutuals:

fr fr bestie, that's the entire page — no hidden options, no env vars, no exit statuses to memorise. she's short, she's sweet, she's iconic 💜

and that's a wrap! this little gem lives in ./drivers/accel/habanalabs/common and the page is dated October 2026 — periodt, go read the source, mwah 🧚💖
