reg , uint32_t acc_flags , uint32_t xcc_id );

🫶 ARGUMENTS 🫶

• adev — amdgpu_device pointer, literally the main character of this call 🦋
• reg — dword aligned register offset, so keep it aligned bestie 📏✨
• acc_flags — access flags which require special behavior, iykyk 💅
• xcc_id — xcc accelerated compute core id, gotta specify which one 🌸
