xe_gt_sriov_vf_bootstrap(9)

💅 xe_gt_sriov_vf_bootstrap — the Kernel API Manual, but make it cute

okay so bestie, welcome to xe_gt_sriov_vf_bootstrap(9) — yes that's a whole mouthful, we're saying it together, don't worry 🫶. It lives in the Kernel API Manual and it's literally gonna query and set up the GuC ABI interface version. main character behaviour tbh ✨

---

🌸 NAME 🌸

xe_gt_sriov_vf_bootstrap — queries the GuC ABI interface version and sets it up. Both. She does it all 💅

✨ SYNOPSIS ✨

int xe_gt_sriov_vf_bootstrap (struct xe_gt *gt);

🎀 ARGUMENTS 🎀

• gt — the xe_gt, obviously 💖 that's the whole thing she gets handed.

🦋 DESCRIPTION 🦋

okay so real talk: this function is for VF use only. Like, not for everyone, it's exclusive, iykyk 🙈.

It requires a functional GuC MMIO based communication to be up and running — no MMIO chat, no bootstrap, periodt.

🌈 RETURN 🌈

• 0 on success 🎉 slay
• a negative error code on failure 😭 so like, vibe check failed

💀 friendly reminder bestie: if you're not a VF, this is not your function. and if the GuC MMIO based communication isn't functional, she's not bootstrapping anything. no cap.
