🫶 ARGUMENTS 🫶

• p — this one's the whole personality tbh, it's a struct amdgpu_vm_update_params * and you gotta see the amdgpu_vm_update_params definition to know what's inside. she's a "go read the struct bestie" situation 💀
• fence — it's a struct dma_fence ** and... it's unused 🙈 like, it's literally just sitting there. not doing anything. main character energy but no lines iykyk 🌸

🌈 DESCRIPTION 🌈

okay so here's the vibe: this function makes sure that the hardware sees the page table updates. that's it. that's the whole thing. she commits the page table update to the HW, and she doesn't gatekeep, she doesn't overexplain, she just makes sure the hardware is caught up ✨🔥

lowkey iconic. no cap. 👑
