💅 xe_gt_sriov_pf_config_set_fair_lmem — Kernel API Manual energy, but make it make sense

okay so bestie, welcome to the Kernel API Manual ✨ and today's main character is xe_gt_sriov_pf_config_set_fair_lmem(9). she provisions a whole squad of VFs with fair LMEM. it's giving "everyone gets a slice, nobody gets to monopolize the snack table." 🍓

---

✨ NAME ✨

xe_gt_sriov_pf_config_set_fair_lmem — provision many VFs with fair LMEM, no cap 🎀

---

🌸 SYNOPSIS 🌸

int xe_gt_sriov_pf_config_set_fair_lmem (struct xe_gt *gt , unsigned int
vfid , unsigned int num_vfs );

---

🦋 ARGUMENTS 🦋

• gt — the xe_gt. and bestie, listen: this one can't be media. like, at all. 🚫
• vfid — the starting VF identifier. can't be 0, iykyk 🙈
• num_vfs — how many VFs you're provisioning. also can't be 0, periodt 💅

---

👑 DESCRIPTION 👑

This function can only be called on PF. that's the whole vibe check — if you're not the PF, this is not your moment, and honestly? iconic boundary-setting. 🔥

---

⭐ RETURN ⭐

0 on success, or a negative error code on failure. simple. clean. slay. ✨
