💖 vcn_v5_0_2_set_irq_funcs — bestie's guide to the Kernel API Manual ✨

okay so you opened the manpage for vcn_v5_0_2_set_irq_funcs(9) and honestly? good for you. this one's short and sweet, but i'm still gonna give you the full tour, no cap 💅

🌸 NAME 🌸

vcn_v5_0_2_set_irq_funcs — literally just: set the VCN block's interrupt irq functions 🎀

---

⭐ SYNOPSIS ⭐

void vcn_v5_0_2_set_irq_funcs (struct amdgpu_device *adev );

that's it. that's the whole vibe. returns void, takes one pointer, moves on with its life 💀

---

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer, bestie. that's the whole description. it's giving "trust me, you know what this is" 🙈

---

💅 DESCRIPTION 💅

so what does it do? it sets the VCN block's interrupt irq functions. periodt. that's the entire documented behaviour, and honestly the manpage is not gonna elaborate further, so neither am i 🫶

lowkey a "you either know the driver or you don't" situation — but now you know it exists, and that's what matters 💖
