💅 ih_v7_0_set_rptr(9) 💅

okay so bestie, welcome to section 9 of the Kernel API Manual ✨ — this is ih_v7_0_set_rptr(9) and it's literally about to set your ring buffer's rptr for you. tiny function, big main character energy 👑

---

🎀 NAME 🎀

ih_v7_0_set_rptr — set the IH ring buffer rptr 🌀

like... that's it. that's the whole vibe. it sets the rptr on the IH ring buffer. slay 💅

---

✨ SYNOPSIS ✨

void ih_v7_0_set_rptr (struct amdgpu_device *adev , struct
amdgpu_ih_ring *ih );

no return value, no drama, she just does the thing 🫶 (yes the void is doing absolutely nothing and we respect her for it)

---

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer 🔥 like, the whole GPU device struct, the big one, the main character
• ih — the IH ring buffer whose rptr we're setting 🌸 (this is the one getting the little pointer update, iykyk)
