xe_gt_sriov..._lmem_locked(9)

💖 xe_gt_sriov..._lmem_locked(9) — a Kernel API Manual moment ✨

okay bestie, welcome to the Kernel API Manual, we're doing a deep dive on one very specific little function and honestly? it's giving "tiny but powerful." no preamble, let's go 🫶

---

🌸 NAME 🌸

xe_gt_sriov_pf_config_get_lmem_locked — Get VF's LMEM quota. that's it, that's the whole thing. lowkey iconic 💅

---

⭐ SYNOPSIS ⭐

u64 xe_gt_sriov_pf_config_get_lmem_locked (struct xe_gt *gt , unsigned
int vfid );

yup, returns a u64. the locked in the name is not a vibe, it's a contract — iykyk 🔒

---

🎀 ARGUMENTS 🎀

• gt — the xe_gt. that's the graphics tile you're poking at, bestie, it's right there in the type name ✨
• vfid — the VF identifier. and listen, it can't be 0 == PFID. zero means Physical Function, which is a whole different thing, so don't even try it 🙈

---

🦋 DESCRIPTION 🦋

This function can only be called on PF. like, that's the entire description. no extra lore, no hidden chapters. if you're not on the Physical Function, this is not your function, periodt 💀

---

💜 RETURN 💜

VF's LMEM quota. that's the number you get back, that's the whole vibe, go spend it wisely 👑

also, the kernel file it lives in: ./drivers/gpu/drm/xe/xe_gt_sriov_pf_config.c — that's home base, that's where she resides 🏠

and that's the whole page, bestie!! you ate that. source is ./drivers/gpu/drm/xe, dated October 2026, and it's all filed under xe_gt_sriov..._lmem_locked(9) — mwah 💋✨
