xe_gt_sriov...gration_size(9)

okay bestie, welcome to the Kernel API Manual glow-up for xe_gt_sriov_pf_migration_size (section 9) — this one is lowkey the group-chat summary of migration data. ✨

🌸 NAME 🌸

xe_gt_sriov_pf_migration_size — total size of migration data from all components within a GT. 💅

✨ SYNOPSIS ✨

ssize_t xe_gt_sriov_pf_migration_size (struct xe_gt *gt , unsigned int
       vfid );

🎀 ARGUMENTS 🎀

• gt — the xe_gt. that's the whole vibe. 🦋
• vfid — the VF identifier (can't be 0, so zero is literally not allowed to sit with us 🙅‍♀️).

💖 DESCRIPTION 💖

This function is for PF only. periodt. that's the entire description, bestie. 💀

🫶 RETURN 🫶

It returns the total migration data size in bytes, or a negative error code on failure. so either a byte count or a sad little negative number. 😭
