xe_gt_sriov...antum_locked(9)

✨ xe_gt_sriov...antum_locked(9) — like, the abbreviated-but-iconic title 💅

okay so real quick bestie: this is a page from the Kernel API Manual, and the full function name is a whole mouthful so the title up there got truncated (iykyk). the actual star of the show is xe_gt_sriov_pf_config_get_exec_quantum_locked. yes it's long. yes it's giving "my password is my birthday" energy. we move. 🫶

🌸 NAME 🌸

xe_gt_sriov_pf_config_get_exec_quantum_locked — literally just go get the PF/VF execution quantum, bestie. that's the whole job. 🎀

---

🦋 SYNOPSIS 🦋

u32 xe_gt_sriov_pf_config_get_exec_quantum_locked (struct xe_gt *gt ,
unsigned int vfid );

look at that. two arguments. a u32 coming back at you. clean, minimal, main character energy. 🔥

---

💖 ARGUMENTS 💖

• gt — the xe_gt. that's your graphics tile, your little guy, your whole reason for being here. ⭐
• vfid — the PF or VF identifier. yes, PF or VF, both are valid, don't @ me. this tells the function whose quantum you're asking about. 👑

---

🧚 DESCRIPTION 🧚

okay so here's the vibe check that actually matters: this function can only be called on PF with the master mutex hold. like, that's not a suggestion, that's the rule. it's a _locked function, babes — the lock is your job, and if you show up without it, that's not a slay, that's a problem. 🙈

(also: PF only. not VF. read it again. PF. 💅)

---

🌈 RETURN 🌈

it hands you back the execution quantum in milliseconds, which is very demure, very mindful of it. 🕐

and if the quantum is infinity? you get 0. yeah. 0 means infinity here. i don't make the rules, i just think they're iconic. 🌀

⚠️ so like, do not see a 0 and assume "no quantum, nothing happening." 0 is infinity. write that down. fr fr. 🍓

💀 one more time for the people in the back: only on PF. master mutex held. the _locked in the name is a promise, not a decoration. 🧚

and that's the whole page, bestie! 🎉 sourced straight from ./drivers/gpu/drm/xe, dated October 2026, and yeah — the footer says xe_gt_sriov...antum_locked(9) again because the title is nothing if not consistent. 💅✨slay
