💅 xe_gt_sriov_pf_config_bulk_set_ctxs — Kernel API Manual energy ✨

Okay so bestie, picture this: you're the Physical Function and you've got a whole squad of Virtual Functions sitting there with no GuC context IDs and honestly? Tragic. This function is the group-chat invite that hands out context IDs to a whole batch of VFs at once, no cap. 🎀

---

✨ NAME ✨

xe_gt_sriov_pf_config_bulk_set_ctxs — Provision many VFs with GuC context IDs. Like, many many. Bulk mode. Group project but everyone actually shows up. 🫶

---

🌸 SYNOPSIS 🌸

int xe_gt_sriov_pf_config_bulk_set_ctxs (struct xe_gt *gt , unsigned int
vfid , unsigned int num_vfs , u32 num_ctxs );

---

🦋 ARGUMENTS 🦋

• gt — the xe_gt. Your Graphics Tile. The main character of this whole situation, lowkey.
• vfid — starting VF identifier. Where the parade begins, bestie. 🎉
• num_vfs — number of VFs to provision. How many besties are getting a gift in this round.
• num_ctxs — requested number of GuC contexts IDs, and here's the kicker: 0 to release. Zero means "actually, take it back," and that's iconic of it. 💅

---

💖 DESCRIPTION 💖

This function can only be called on PF. That's the whole rule, fr fr — no sneaky VF behavior allowed, this is PF-only territory, periodt.

---

🔥 RETURN 🔥

0 on success, or a negative error code on failure. That's it, that's the vibe check. 😭
