📦 version 7.3.1, in nixpkgs unstable

✨ xe_sriov_pf..._query_vf_eq(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's all about peeking at a VF's execution quantum, and honestly? it's giving "short but iconic." let's get into it 🎀

🌸 NAME 🌸

xe_sriov_pf_provision_query_vf_eq — literally just Query VF's execution quantum. that's it. that's the whole vibe. 🦋

🫶 SYNOPSIS 🫶

int xe_sriov_pf_provision_query_vf_eq (struct xe_device *xe , unsigned
int vfid , u32 *eq );

she takes three things and returns an int, periodt. 💅

💜 ARGUMENTS 💜

  • xe — the PF xe_device. like, the whole device bestie, not a VF. 🖥️
  • vfid — the VF identifier. which VF are we talking about, girlie? 🔢
  • eq — placeholder for the returned execution quantum, measured in [ms]. yes, milliseconds, keep up 💅 ⏱️

⭐ DESCRIPTION ⭐

so what does she do? she queries the VF's execution quantum (EQ) provisioning from all tiles/GTs. all of them. no cap. 🌈

and here's the tea 🍵 — if the values across those tiles/GTs are inconsistent, you get a -EUCLEAN error back. not a vibe, but forewarned is forearmed fr fr.

⚠️ important bestie: this function can only be called on PF. don't try it anywhere else, it's not that girl. 🙈

🔥 RETURN 🔥

  • 0 on success 🎉 slay
  • a negative error code on failure 😭 that's it, that's the contract
