💖 enable_ecrc_checking(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a little function with a big job — it's all about turning on ECRC checking for a PCIe device, and honestly? she's iconic for it 💅

---

🌸 NAME 🌸

enable_ecrc_checking — enable PCIe ECRC checking for a device 🧚

---

🎀 SYNOPSIS 🎀

int enable_ecrc_checking (struct pci_dev *dev );

like, that's the whole vibe. one function, one arg, no cap 🫶

---

🦋 ARGUMENTS 🦋

• dev — the PCI device 💻 that's it, that's the argument. she's the main character here 👑

---

⭐ RETURN ⭐

Returns 0 on success, or a negative value on failure 😭 so like, check it, fr fr — if it comes back negative something went sideways and you should probably pay attention 🙈
