💅 xe_gt_sriov_pf_config_bulk_set_lmem — bestie's own Kernel API Manual moment ✨

okay so this is a page from the Kernel API Manual, and it's about one (1) function that does one (1) thing: handing out LMEM to a whole squad of VFs at once. no cap, it's lowkey iconic 🫶

🌸 NAME 🌸

xe_gt_sriov_pf_config_bulk_set_lmem — Provision many VFs with LMEM.

like, many. not one. that's the whole point, bestie 💖

✨ SYNOPSIS ✨

int xe_gt_sriov_pf_config_bulk_set_lmem(struct xe_gt *gt, unsigned int vfid, unsigned int num_vfs, u64 size);

🎀 ARGUMENTS 🎀

  • gt — the xe_gt (can't be media). sorry media girlies, this one's not for you 🙈
  • vfid — starting VF identifier (can't be 0). zero is right out, fr fr
  • num_vfs — number of VFs to provision. yes, this is the "bulk" part ✨
  • size — requested LMEM size. it's a u64, it's chonky, it's giving main character energy 🔥

💜 DESCRIPTION 💜

This function can only be called on PF.

that's it. that's the whole description. short king 👑 — and honestly it's a hard boundary, not a suggestion, so don't try it anywhere else or the vibe check will not go your way 💀

🌈 RETURN 🌈

0 on success or a negative error code on failure.

so: 0 = slay ✅, anything negative = 😭

🦋 SEE ALSO 🦋

the kernel file lives right here, bestie:

  • ./drivers/gpu/drm/xe/xe_gt_sriov_pf_config.c

and the whole extended friend group, in order:

iykyk — that's a lot of cousins at this family reunion 💀 but every single one is invited, no gatekeeping here 💖

cute little reminder from your girl: vfid can't be 0 and gt can't be media. those are the rules, and we respect the rules 🎀

and that's the page, bestie!! 🧚‍♀️ this one ships out of ./drivers/gpu/drm/xe and it's dated October 2026 — so like, future-era slay ⭐ mwah, go provision responsibly 💅✨
