xe_sriov_pf...k_apply_vram(9)

💅 xe_sriov_pf_provision_bulk_apply_vram(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel docs, the manual name is Kernel API Manual, and this one function is about to be your new obsession. it's giving "one call to rule all the VFs" energy. let's get into it 🫶

✨ NAME ✨

xe_sriov_pf_provision_bulk_apply_vram — literally just changes the VRAM provisioning for all the VFs at once. no cap, all of them. 🎀

---

🌸 SYNOPSIS 🌸

int xe_sriov_pf_provision_bulk_apply_vram (struct xe_device *xe , u64
size );

---

🦋 ARGUMENTS 🦋

• xe — the PF xe_device. yeah, the Physical Function one. it's the main character here 👑
• size — the VRAM size in [bytes] you want to set. bytes, bestie, so bring your calculator 💀

---

💖 DESCRIPTION 💖

So what it actually does: it changes all VFs' VRAM (that's LMEM, for the uninitiated) provisioning — across all tiles. every tile. all of them. 🌈

🚨 real talk though: this function can only be called on PF. like, don't even try it anywhere else. iykyk.

🔥 RETURN 🔥

• 0 on success — slay, we ate 💅
• a negative error code on failure — not slay, go read the error 😭
