📦 version 7.3.1, in nixpkgs unstable

💖 pdc_pat_cpu_get_number(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function called pdc_pat_cpu_get_number, living its best life in section 9, and honestly? it does exactly one thing and it does it slayfully 💅

✨ NAME ✨

pdc_pat_cpu_get_number — retrieve the cpu number 🫶

🌸 SYNOPSIS 🌸

int pdc_pat_cpu_get_number (struct pdc_pat_cpu_num *cpu_info , unsigned
long hpa );

yeah that's the whole signature, no cap 💀 it takes a pointer and a unsigned long, returns an int, and honestly it's giving "small but mighty" 👑

🦋 ARGUMENTS 🦋

  • cpu_info — the return buffer 💌 like, this is where the answer gets dropped off. it literally says "the return buffer" and that's the whole vibe.
  • hpa — the Hard Physical Address of the CPU 🧚 this is not a regular address, it's the Hard Physical Address, so treat it with the respect it deserves.

💅 DESCRIPTION 💅

okay so here's the tea ☕: this function retrieves the cpu number for the cpu sitting at the specified HPA. that's it. that's the function. you hand it an HPA, it hooks you up with the matching cpu number 🔥

literally the most straightforward glow-up in the whole firmware file, and we respect that 🙈
