🦋 SYNOPSIS 🦋

uint64_t amdgpu_ttm_domain_start (struct amdgpu_device *adev , uint32_t
type );

like, yes, that's the whole signature, no cap ✨

💖 ARGUMENTS 💖

• adev — amdgpu device object 👑 this is the device you're asking about, the main character of the operation
• type — type of the memory 🧚 literally which kind of memory you mean, bestie
