✨ xe_gt_sriov_pf_control_sync_flr(9) ✨

okay bestie, you’re in the Kernel API Manual and this header is literally xe_gt_sriov...rol_sync_flr(9) — the full main-character function is xe_gt_sriov_pf_control_sync_flr, and it’s here to synchronize on the VF FLR checkpoint. short page, iconic energy, every detail stays 🫶

🎀 SYNOPSIS 🎀

int xe_gt_sriov_pf_control_sync_flr (struct xe_gt *gt , unsigned int
vfid , bool sync );

---

🦋 ARGUMENTS 🦋

• gt — the xe_gt. literally the GT in question 💅
• vfid — the VF identifier. the VF’s lil ID 🫶
• sync — if true it will allow to exit the checkpoint. that’s the toggle, bestie 🎚️
