xe_gt_sriov...ority_locked(9)

💅 xe_gt_sriov...ority_locked(9) — bestie edition

okay so this is from the Kernel API Manual, and the function's full government name is xe_gt_sriov_pf_config_force_sched_priority_locked (the header up top just abbreviates it because even the manpage was like "girl that's long"). sit down, hydrate, let's go 🍓

---

✨ NAME ✨

xe_gt_sriov_pf_config_force_sched_priority_locked — force update scheduling priority. that's it. that's the whole vibe. it forces, it updates, it's about priority, and yes it's locked (the name says so, respect it) 👑

---

🌸 SYNOPSIS 🌸

void xe_gt_sriov_pf_config_force_sched_priority_locked (struct xe_gt *gt
, u32 priority );

returns void btw — so like, no return value, it just Does The Thing and leaves. main character energy fr fr ✨

---

🎀 ARGUMENTS 🎀

• gt — the xe_gt. the gt in question. your gt. handle with care 🫶
• priority — the new scheduling priority to set. brand new value, who dis 💅

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function lets you update the cached values of the scheduling priorities of all the VFs and the PF too, and it happens as a result of applying the GUC_KLV_VGT_POLICY_SCHED_IF_IDLE_ policy. every single one of them gets the glow-up, no VF left behind 💖

⚠️ and listen — this function can only be called on PF. not VF. PF. that's the rule, that's the boundary, do not test it 😭
