💅 vcn_v2_0_hw_init — the kernel API glow-up you didn't know you needed

okay so bestie, we're in the Linux kernel API manual today and the page we're stanning is vcn_v2_0_hw_init(9) ✨ if you were looking for the header line, that's it — title vcn_v2_0_hw_init and manual name vcn_v2_0_hw_init(9), both right there, no cap 🎀

that's the whole vibe. returns an int, takes one pointer. slay 💅

so what does it actually do? three things, icon behavior only:

1. Initialize the hardware 🌈
2. boot up the VCPU 🔥
3. do some testing ⭐

that's it, that's the whole description. it's giving "load-bearing one-liner" and honestly? it ate 💀
