🌸 NAME 🌸

xe_gt_sriov_pf_control_stop_vf — Stop a VF. that's it. that's the whole vibe. 💅

🦋 SYNOPSIS 🦋

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

like, that's the whole signature, no cap — one struct xe_gt * and one unsigned int, and it hands you back an int. iconic behavior honestly 🎀

---

✨ ARGUMENTS ✨

• gt — the xe_gt 👑 this is the graphics tile you're working with, the main character of the whole operation.
• vfid — the VF identifier 🔥 aka which virtual function we're talking about. gotta know who you're stopping, bestie.

---

💜 DESCRIPTION 💜

so here's the tea ☕ this function is for PF only. like, PF only. don't come at it as a VF, it's not gonna happen for you, periodt. 🙈

(PF = the Physical Function, the one actually running the show. iykyk.)
