xe_gt_sriov...rol_wait_flr(9)

💅 xe_gt_sriov_pf_control_wait_flr — like, the whole vibe ✨

Okay bestie, so this page lives in the Kernel API Manual (yes, that manual, the one all the kernel girlies use), and it's all about one little function that literally just sits there and waits for a VF FLR to finish. Iconic. Lowkey underrated. Let's get into it 🫶

---

🌸 NAME 🌸

xe_gt_sriov_pf_control_wait_flr — wait for a VF FLR to complete. That's it. That's the whole job. It waits. It completes. Slay.

---

✨ SYNOPSIS ✨

int xe_gt_sriov_pf_control_wait_flr (struct xe_gt *gt , unsigned int
vfid );

So you hand it a gt and a vfid, and it gives you back an int. Simple. Clean. No cap 💖

---

🎀 ARGUMENTS 🎀

• gt — the xe_gt. Your graphics tile. Your main character. You know her, you love her 💫
• vfid — the VF identifier. Like a little name tag so the function knows which VF we're talking about. iykyk 🏷️

---

🦋 DESCRIPTION 🦋

So the one thing you literally cannot miss here: this function is for PF only. Periodt. Not VF. PF. If you're a VF bestie, this is not your moment, sorry not sorry 🙈

For the PF girlies, though? It's giving "wait for a VF FLR to complete," and it does exactly what it says on the tin. No plot twists. No surprises. Just vibes and patience ⏳

---

🔥 RETURN 🔥

• 0 on success — we love a happy ending 💚
• a negative error code on failure — and honestly? 😭 at least it tells you

Ngl, if you're a VF reading this hoping for a little something — this page isn't for you. PF only. That's the rule. 💀

Okay that's the whole page bestie, hope it ate 🍓💜 Mwah! This lil' beauty comes from ./drivers/gpu/drm/xe and it's dated October 2026 — mark your calendars, the future is now, and the manual name is still xe_gt_sriov...rol_wait_flr(9) in case you forgot ✨🧚‍♀️
