🎀 NAME 🎀

okay so bestie, welcome to the Kernel API Manual page for xe_sriov_packet_read_single(9) — it's lowkey iconic and it's here to read migration data from a single packet ✨💅

xe_sriov_packet_read_single — Read migration data from a single packet.

✨ SYNOPSIS ✨

here's the signature, bestie — copy it exactly, no autocorrect energy 🙈:

       ssize_t xe_sriov_packet_read_single (struct xe_device *xe , unsigned int
       vfid , char __user *buf , size_t len );

🧚 ARGUMENTS 🧚

• xe — the xe_device, obvi 💖
• vfid — the VF identifier, periodt.
• buf — start address of userspace buffer, iykyk 🦋
• len — requested read size from userspace, no cap.

🔥 RETURN 🔥

• the number of bytes that has been successfully read — slay, that's your data right there 💖
• 0 if no more migration data is available — the "we're done here" moment ✨
• -errno on failure — not iconic, but that's how the error shows up 😭
