amdgpu_vm_update_shared(9)

💖 amdgpu_vm_update_shared(9) 💖

okay bestie, welcome to the Kernel API Manual page for amdgpu_vm_update_shared(9) — it's giving tiny helper with big lock energy 💅✨

---

✨ NAME ✨

amdgpu_vm_update_shared — helper to update shared memory stat 🫶

---

🌸 SYNOPSIS 🌸

void amdgpu_vm_update_shared (struct amdgpu_vm_bo_base *base );

---

🎀 ARGUMENTS 🎀

• base — base structure for tracking BO usage in a VM 👑

---

💅 DESCRIPTION 💅

so the way this works: it takes the vm stats_lock and updates the shared memory stat 🔒✨

and listen, if the basic stat changed (e.g. a buffer was moved), then amdgpu_vm_update_stats also needs to be called as well — no skipping that step, bestie 😭🫶
