bdx_fw_load(9)

Bestie, welcome to bdx_fw_load(9) from the Kernel API Manual 💖 this page is literally about loading firmware to a NIC, and it's giving “delivery driver, but make it kernel” 🚚✨. No cap.

🌸 NAME 🌸

• bdx_fw_load — loads firmware to NIC. That's it, that's the name section, periodt 💅

✨ SYNOPSIS ✨

The function signature is right here, copy it exactly:

int bdx_fw_load (struct bdx_priv *priv );

🎀 ARGUMENTS 🎀

• priv — NIC private structure. aka her little state bag 👜

🦋 DESCRIPTION 🦋

Okay so the tea ☕: firmware is loaded via the TXD fifo, so it must be initialized first. No TXD fifo init, no firmware delivery — that's the vibe.

Firware must be loaded once per NIC, not per PCI device provided by NIC (NIC can have few of them). Yes, keep the spelling “Firware” — I'm not touching it, bestie 😭.

So all drivers use the semaphore register to choose one that will actually load FW to NIC. It's literally a little driver election, and only the chosen one gets to do the firmware-loading main character moment 👑.

💅 SEE ALSO 💅

Kernel file: ./drivers/net/ethernet/tehuti/tehuti.c — yes, that's the exact path, go look 👀.
