💅 xe_sriov_pf_migration_restore_produce 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a whole function, xe_sriov_pf_migration_restore_produce, and it's basically the little messenger that hands a VF migration data packet over to the device 🎀 no cap.

🌸 NAME 🌸

xe_sriov_pf_migration_restore_produce — produce a VF migration data packet to the device 💌

🦋 SYNOPSIS 🦋

int xe_sriov_pf_migration_restore_produce(struct xe_device *xe,
                                          unsigned int vfid,
                                          struct xe_sriov_packet *data);

🎀 ARGUMENTS 🎀

  • xe — the xe_device 👑 like, the whole device, that's the main character here
  • vfid — the VF identifier 🔢 tells you which VF we're talking about
  • data — pointer to xe_sriov_packet 📦 the actual packet, the payload, the whole point

✨ DESCRIPTION ✨

So here's the vibe 🫶 this gets called by the restore migration data producer (that's userspace, btw) when it's processing migration data 💖

and if the underlying data structure is full? it just waits until there's space 🧚 no error, no drama, it sits there patiently like a good little function 😭 literally the chillest behavior.

lowkey important: this is the "wait for room" situation, not a "bail out" situation — it holds until space frees up 💅

⭐ RETURN ⭐

  • 0 on success 🌈 slay
  • a negative error code on failure 💀 not slay, but at least it's honest
