mei_me_fw_type_nm(9)

🌸 NAME 🌸

Hey bestie, you're on the mei_me_fw_type_nm(9) page from the Kernel API Manual 🫶. The NAME is literally: mei_me_fw_type_nm — check for nm sku. Yes, lowercase nm and lowercase sku, we respect the source 💅.

✨ SYNOPSIS ✨

Signature time, copied exactly because code is sacred 🎀:

bool mei_me_fw_type_nm (const struct pci_dev *pdev );

🎀 ARGUMENTS 🎀

• pdev — pci device 💻. That's the whole argument, no cap.

💅 DESCRIPTION 💅

Okay so this function reads the ME FW Status register to check for the Node Manager (NM) Firmware 👑.

The NM FW is only signaled in PCI function 0. That's the important bit, fr fr ✨.

Note: Deprecated by PCH8 and newer 👵💀. Like, she's iconic, but she's old news on PCH8 and newer.

🦋 RETURN 🦋

Returns true in case of NM firmware 💖. That's it, that's the return vibe check 🎀.
