xe_gt_sriov_...t_fair_sched(9)

💖 xe_gt_sriov_...t_fair_sched(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this little cutie is a section 9 page and honestly it's giving "gatekeeper of fairness" energy. sit down, hydrate, let's go 🫶

---

🌸 NAME 🌸

xe_gt_sriov_pf_config_set_fair_sched — provision PF and VFs with fair scheduling 💅

like… it's the function that makes sure everybody gets their lil slice of the scheduler pie. no cap, it's giving equal-share icon.

---

✨ SYNOPSIS ✨

int xe_gt_sriov_pf_config_set_fair_sched (struct xe_gt *gt , unsigned
       int num_vfs );

---

🎀 ARGUMENTS 🎀

• gt — the xe_gt, aka the graphics tile in question. your main character struct, lowkey 🦋
• num_vfs — how many VFs you wanna provision. and listen: it can't be 0 🚫 zero VFs is not a thing here, don't even try it. that's the rule, periodt.

---

💜 DESCRIPTION 💜

This function can only be called on PF. that's it, that's the whole description, bestie — short and iconic 🙈 like it literally says nothing else. so yeah, PF only, no VF sneaky business, iykyk.

---

🌈 RETURN 🌈

• 0 on success 🎉 slay
• a negative error code on failure 😭 (you'll know, it'll tell you)

💀 reminder bestie: PF only. do not come at this from a VF, it will not end cute.

okay that's the page, mwah 🍓 this little legend ships out of ./drivers/gpu/drm/xe and was dated October 2026, filed under xe_gt_sriov_...t_fair_sched(9) — go forth and schedule fairly, queen 👑💖
