int vcn_v1_0_sw_init (struct amdgpu_ip_block *ip_block );

🎀 ARGUMENTS 🎀

• ip_block — a pointer to the amdgpu_ip_block for this hw instance. that's it, that's the whole argument, she's lowkey simple like that 💅

🦋 DESCRIPTION 🦋

okay so what this does is literally just: load firmware and do the sw initialization. that's the vibe. firmware gets loaded, software gets init'd, main character energy all around 👑
