vi_srbm_select(9)

💅 vi_srbm_select(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — we're talking about vi_srbm_select, and honestly? it's giving "tiny function, big main character energy" 👑

---

🎀 NAME 🎀

vi_srbm_select — pick out exactly which register instances you're talking to 💖

---

✨ SYNOPSIS ✨

void vi_srbm_select (struct amdgpu_device *adev , u32 me , u32 pipe ,
u32 queue , u32 vmid );

---

🌸 ARGUMENTS 🌸

• adev — an amdgpu_device pointer, aka your ticket into the GPU's whole world 🫶
• me — the selected ME (micro engine) 👑
• pipe — the pipe, yes literally just "pipe" 💀
• queue — the queue 🧚
• vmid — the VMID 🌈

---

🦋 DESCRIPTION 🦋

So what does it actually do? It switches up which register instances are currently active — like changing the channel on the whole vibe of the hardware 📺✨

Some registers are instanced per VMID, and others are instanced per me/pipe/queue combination — so yeah, this little function is lowkey holding the whole "which one am I even talking to right now" situation together 💅 no cap.
