💅 xe_sriov_pf..._query_vf_pt(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — we're talking about xe_sriov_pf_provision_query_vf_pt, and the whole vibe is “PF, please go ask the provisioning bits what the VF’s preemption timeout is.” No cap. 🫶

---

🌸 NAME 🌸

xe_sriov_pf_provision_query_vf_pt — Query VF's preemption timeout. 💖

---

✨ SYNOPSIS ✨

       int xe_sriov_pf_provision_query_vf_pt (struct xe_device *xe , unsigned
       int vfid , u32 *pt );

---

🫶 ARGUMENTS 🫶

• xe — the PF xe_device, bestie. That's the device arg, and it’s giving PF main character energy. 💜
• vfid — the VF identifier. Which VF are we talking about? This one. 🎀
• pt — placeholder for the returned preemption timeout in [us]. It’s literally where the returned value goes, ngl. 🙈

---

💖 DESCRIPTION 💖

So this function queries the VF's preemption timeout (PT) provisioning from all tiles/GTs — all of them, no cherry-picking. 🍓

If the values across tiles/GTs are inconsistent, then -EUCLEAN error will be returned. 😭 That’s the vibe check, and it did not pass.

And the big important thing: this function can only be called on PF. PF only. Periodt. 👑

---

🎀 RETURN 🎀

0 on success or a negative error code on failure — that's the whole return situation, bestie. 💫
