amdgpu_debugfs_regs_init(9)

✨ amdgpu_debugfs_regs_init 💅

okay so bestie, we're in the Kernel API Manual today, and this is the function that sets up your debugfs register-access situation for an AMD GPU. yes it's a kernel thing. yes it's iconic. let's go 🫶

---

🌸 NAME 🌸

amdgpu_debugfs_regs_init — the one that initializes the debugfs entries that give you register access. that's it, that's the whole vibe. it's literally giving "let me peek at your registers" ✨

---

🎀 SYNOPSIS 🎀

int amdgpu_debugfs_regs_init (struct amdgpu_device *adev );

like, one arg, returns an int. clean. minimal. main character energy fr fr 💅

---

🦋 ARGUMENTS 🦋

• adev — the device you're attaching these debugfs entries to. that's your struct amdgpu_device *, your GPU-in-code-form, the whole reason we're here 💖
