✨ xe_gt_sriov_...meout_locked(9) ✨

okay so bestie, we're deep in the Kernel API Manual today — like, deep deep, the ./drivers/gpu/drm/xe corner of the kernel where the SR-IOV PF config girlies live 💅 don't worry, I got you, this one's actually a chill little getter, let's go 🫶

---

🌸 NAME 🌸

xe_gt_sriov_pf_config_get_preempt_timeout_locked — bestie. it literally just gets the PF/VF preemption timeout. that's the whole vibe. no cap 🎀

---

⭐ SYNOPSIS ⭐

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

like look at her. two args. returns a u32. iconic, unbothered, hydrated 💖

---

🦋 ARGUMENTS 🦋

• gt — the xe_gt, aka the GT we're talking about. the main character of the operation, fr fr 👑
• vfid — the PF or VF identifier — so, which PF, or which VF, you're asking about. pick your fighter 🎀

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕ — this function can only be called on a PF, and you gotta be holding the master mutex. like, _locked is literally in the name bestie, the universe is telling you something 😭 obviously 🙈

not me calling this without the master mutex... that's a vibe check you will FAIL 💀

---

🔥 RETURN 🔥

the preemption timeout, in microseconds. periodt. 💅

and if it's infinity? you get 0. yeah, zero means infinity here, don't ask, it's giving off-by-void, but that's what the docs say so we're rolling with it ✨
