xe_tile_sri...gfs_populate(9)

💅 NAME 💅

xe_tile_sriov_pf_debugfs_populate — okay so this one populates the SR-IOV debugfs tree with tile files, bestie. That's the whole vibe. ✨

So this is page xe_tile_sri...gfs_populate(9) from the Kernel API Manual, and we're gonna get into it.

🌸 SYNOPSIS 🌸

void xe_tile_sriov_pf_debugfs_populate (struct xe_tile *tile , struct dentry *parent , unsigned int vfid );

🎀 ARGUMENTS 🎀

• tile — the xe_tile to register. this is the little guy we're setting up 💖
• parent — the parent dentry that represents the SR-IOV vfid function. it's giving "the folder we're about to decorate" energy 🗂️
• vfid — the VF identifier. literally just the VF's id, no cap 🪪

🦋 DESCRIPTION 🦋

okay so here's what it does: it adds a new debugfs directory to the parent directory — that new directory is gonna represent a tile — and then it populates that directory with files that are related to the SR-IOV vfid function. iconic behavior honestly 👑

⚠️ big important note: this function can only be called on PF. like, PF only, periodt. don't come at it with anything else 🙈
