amdgpu_driver_open_kms — the drm callback for open. that's it, that's the whole vibe. it's the function that gets called when somebody opens the device 🫶

---

🌸 SYNOPSIS 🌸

int amdgpu_driver_open_kms (struct drm_device *dev , struct drm_file
       *file_priv );

literally takes two pointers and hands you back an int. simple, iconic, no cap ✨

💜 DESCRIPTION 💜

so when the device gets opened, this function inits vm on cayman+ (and that's all asics, fr fr — not just the fancy new ones). then it reports back: it returns 0 on success, and an error on failure. no drama, just return codes 😭
