xe_gt_sriov_...ss_save_data(9)

💖 xe_gt_sriov_pf_control_process_save_data — a Kernel API Manual moment 💖

okay so this is a page from the Kernel API Manual (yes, that's the manual name, we're being fancy today ✨) and it's all about one little function that queues up VF save migration data processing. bestie, it's giving "small function, big job" energy and i'm obsessed 🎀

---

🌸 NAME 🌸

xe_gt_sriov_pf_control_process_save_data — queue VF save migration data processing. that's the whole vibe. it queues. the data gets processed. slay 💅

---

✨ SYNOPSIS ✨

int xe_gt_sriov_pf_control_process_save_data (struct xe_gt *gt ,
unsigned int vfid );

look at her. two args, one int return. iconic, no notes 🫶

---

🦋 ARGUMENTS 🦋

• gt — the xe_gt. that's it. that's the whole description. it's the gt. the graphics tile. the main character of this parameter list 👑
• vfid — the VF identifier. the little number that tells you which virtual function we're talking about 💫

---

🌈 DESCRIPTION 🌈

okay so real talk: this function is for PF only. like, Physical Function only, periodt. don't come at it from anywhere else, it is simply not that girl 🙈

---

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code on failure 😭 (yes, negative, we're in kernel land, everything's a negative errno and that's just how it is fr fr)

lowkey a reminder that this one is PF only — if you're not the Physical Function, this page is not for you and the function will not be either 💀

okay that's the page!! mwah 💋 this little baby comes to you from the source path ./drivers/gpu/drm/xe, dated October 2026, and you can find her filed under xe_gt_sriov_...ss_save_data(9). drink some water, go call your mom, ily bye 🍓💖
