amdgpu_atombios_init(9)

💖 NAME 💖

amdgpu_atombios_init — init the driver info and callbacks for atombios. Okay bestie, this is amdgpu_atombios_init(9) from the Kernel API Manual, and it's literally here to set up the driver info and callbacks for atombios 💅

📜 SYNOPSIS 📜

int amdgpu_atombios_init (struct amdgpu_device *adev );

🧡 ARGUMENTS 🧡

• adev — an amdgpu_device pointer. That's the device struct you're handing over 🫶

✨ DESCRIPTION ✨

okay so here's the tea: this function initializes the driver info and register access callbacks for the ATOM interpreter (r4xx+). It returns 0 on sucess — yes, “sucess,” that's the manpage's spelling, not me 😭 — and -ENOMEM on failure. It's called at driver startup, so it's giving first-day-of-school energy 👑
