xe_gt_sriov...licy_restart(9)

🌸 NAME 🌸

xe_gt_sriov_pf_policy_restart — bestie, this one reprovisions your policy settings. That's the whole job. It resets the policy config back into place, and honestly? It ate. 💅

(Also hi, welcome to the Kernel API Manual 💖 — yes, the page title up top got chopped to xe_gt_sriov...licy_restart(9) because terminal headers are dramatic like that, but the real full name is the one right above, no cap.)

---

✨ SYNOPSIS ✨

int xe_gt_sriov_pf_policy_restart (struct xe_gt *gt );

That's it. One function, one argument, returns an int. Clean. Minimal. Main character energy. 🎀

---

🦋 ARGUMENTS 🦋

• gt — the xe_gt. Like, the GT struct. That's the thing you're handing over. 🫶

---

💜 DESCRIPTION 💜

Okay so here's the one thing you cannot miss, bestie:

This function can only be called on PF.

That's it, that's the description. Only on PF. Not VF. PF. Periodt. If you're not on a PF, this is not your moment, and the vibes will be immaculate but the function will not be for you. 🙈

---

⭐ RETURN ⭐

• 0 on success 🎉 — slay, it worked.
• a negative error code on failure 😭 — not slay, but at least it's honest about it.
