💅 xe_sriov_vfio_error 💅

okay so bestie, welcome to the Kernel API Manual page for xe_sriov_vfio_error — yes it's a 9-section kernel page, yes we're reading it, and yes it's actually kind of iconic.

---

✨ NAME ✨

xe_sriov_vfio_error — literally just yeets a VF device into the error state. that's the whole job. 🫶

---

🌸 SYNOPSIS 🌸

int xe_sriov_vfio_error (struct xe_device *xe , unsigned int vfid );

---

🎀 ARGUMENTS 🎀

• xe — the PF xe_device, and no you can't just make one up: you get it by calling xe_sriov_vfio_get_pf. go get it properly, bestie. 💖
• vfid — the VF identifier. important: it can't be 0. zero is not invited to this party 🙅‍♀️

---

🦋 DESCRIPTION 🦋

so like… reset is needed to move it out of error state. that's it, that's the lore. no cap. ✨

note to self: this thing puts the device INTO error state — getting it back OUT is a whole separate reset moment. don't forget the second part 💀

---

🔥 RETURN 🔥

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