✨ xe_gt_sriov_vf_gmdid ✨

okay so bestie, welcome to the <pink>xe_gt_sriov_vf_gmdid(9)</pink> page from the Kernel API Manual 📖💖 — it's a tiny little function but it's got main character energy in the VF world, and we're gonna get you comfy with it fr fr.

🎀 NAME 🎀

xe_gt_sriov_vf_gmdid — it queries the GMDID over MMIO 💅 like, that's the whole vibe.

🌸 SYNOPSIS 🌸

u32 xe_gt_sriov_vf_gmdid (struct xe_gt *gt );

That's it. One arg. One u32 back. Slay. ✨

🦋 ARGUMENTS 🦋

  • gt — the xe_gt 🫶 (that's the graphics tile bestie, you're handing it over)

💜 DESCRIPTION 💜

So here's the tea ☕ — this function is for VF use only 👑. Like, VF-only. Nobody else gets in. That's the entire description, no cap 😭💀 (short and iconic, honestly).

🌈 RETURN 🌈

On success you get the value of the GMDID KLV 🎀✨ — and if it fails? You get 0 🙈. That's it, that's the whole deal.

⭐ heads up bestie: 0 means failure here, so don't be out here treating a zero like it's a real value, okay? 💅
