✨ gfx_v7_0_cp_gfx_start(9) ✨

okay so bestie, welcome to the Kernel API Manual page for gfx_v7_0_cp_gfx_start(9) — yes the whole thing is named after the function, iconic behavior, we love a self-titled moment 💅

---

🌸 NAME 🌸

gfx_v7_0_cp_gfx_start — literally just here to start the gfx ring, that's it, that's the whole job 🎀

---

🦋 SYNOPSIS 🦋

int gfx_v7_0_cp_gfx_start (struct amdgpu_device *adev );

bestie it takes exactly one (1) argument and it returns an int, no cap 🫶

---

💖 ARGUMENTS 💖

• adev — an amdgpu_device pointer, i.e. the whole GPU device situation. hand it over, that's the vibe ✨

---

🔥 DESCRIPTION 🔥

so what does it do? it enables the ring, then it loads the clear state context, plus all the other packets you need to init the ring. that's the whole glow-up 🧚

and because we're responsible main characters: it returns 0 for success, and an error for failure. periodt 💀

ngl, if you get something other than 0 back, that's your vibe check failing — something went wrong, go look at it 🙈
