get_gnr_mdev(9)

💖 NAME 💖

okay so bestie, welcome to the get_gnr_mdev(9) page in the Kernel API Manual 💅 this is literally the manual for get_gnr_mdev — Get the PCI device of the @logical_idx-th DDR memory controller. no cap, that's the whole name vibe. 🦋

✨ SYNOPSIS ✨

struct pci_dev * get_gnr_mdev (struct skx_dev *d , int logical_idx , int *physical_idx );

🌸 ARGUMENTS 🌸

• d — the pointer to the structure of CPU socket EDAC device. like, the CPU socket EDAC device struct pointer, periodt. 💜
• logical_idx — the logical index of the present memory controller (0 ~ max present MC# - 1). so it's the logical index of a present MC, and the range is literally 0 through max present MC# - 1. ✨
• physical_idx — to store the corresponding physical index of logical_idx. this is your spot to store the matching physical index, bestie. 🎀

🔥 RETURN 🔥

The PCI device of the logical_idx-th DDR memory controller, and NULL on failure. so if it works you get the PCI device; if it fails you get NULL — that's the whole return tea. 😭
