xe_gt_sriov_...trol_restart(9)

✨ NAME ✨

xe_gt_sriov_pf_control_restart — bestie, this is the one that restarts the SR-IOV control data after a GT reset 💅 (this page lives in the Kernel API Manual, section 9, so you know it's the real deal).

---

🌸 SYNOPSIS 🌸

void xe_gt_sriov_pf_control_restart (struct xe_gt *gt );

---

🎀 ARGUMENTS 🎀

• gt — the xe_gt 🦋 (yes, that's the whole description, she's a woman of few words and honestly? iconic)

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — any per-VF status that the PF is holding onto, and any ongoing VF control activity the PF is doing, must be reset or cancelled when the GT gets reset. No exceptions, no "but I was almost done", nothing. It all gets wiped 🧹✨

This function is for PF only, periodt. Don't come at it from the VF side, it's not for you 🙈
