💅 xe_sriov_pf...uery_vf_vram(9)

okay bestie, welcome to the Kernel API Manual — yes this is a real manual page name, yes it's lowkey cursed, and yes the title got truncated with ... and we're just gonna vibe with it 🫶

✨ NAME ✨

xe_sriov_pf_provision_query_vf_vram — the function that queries a VF's VRAM allocation. that's it, that's the whole name, it ate 💅

🌸 SYNOPSIS 🌸

int xe_sriov_pf_provision_query_vf_vram (struct xe_device *xe , unsigned
int vfid , u64 *size );

literally just three args and an int return, no cap. copy it exactly, don't be cute with it 🎀

🦋 ARGUMENTS 🦋

  • xe — the PF xe_device. the main character itself 👑
  • vfid — the VF identifier. and nope, it can't be 0 because 0 == PFID, so don't even try it 🙈
  • size — a placeholder where the returned VRAM size gets dropped. hand it over empty, it comes back iconic ✨

💖 DESCRIPTION 💖

So what does it actually do? It queries the VF's VRAM provisioning from all tiles/GTs — like, all of them, not just one, we're thorough here 💯

⚠️ important vibe check: this function can only be called on PF. PF only. do not come at it from anywhere else, it's giving "members only" energy 🚫

🌈 RETURN 🌈

  • 0 on success 🎉
  • a negative error code on failure 😭

that's the whole contract, bestie. no in-between, no "kinda worked", fr fr.

🎀 SEE ALSO 🎀
