🌸 NAME 🌸

vcn_v4_0_resume — literally the function that resumes the VCN block. that's it, that's the vibe. 💅

🦋 SYNOPSIS 🦋

int vcn_v4_0_resume (struct amdgpu_ip_block *ip_block );

she takes one thing and returns an int, periodt. ✨

💜 ARGUMENTS 💜

  • ip_block — a pointer to the amdgpu_ip_block for this hw instance. like, the specific one, not a random other one, iykyk. 👑

🔥 DESCRIPTION 🔥

so what does she actually do? she resumes the firmware and does the hw init for the VCN block. that's the whole assignment and she ate. 💅 no cap, that's genuinely the entire description — firmware resume plus hardware init, together, one function, main character energy. 🌈
