💅 eeh_pe_inject_err(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for eeh_pe_inject_err — yes that's a lot of letters, no I will not be pronouncing it out loud, but I will explain it because it's genuinely kinda iconic 🎀

🌸 NAME 🌸

eeh_pe_inject_err — injecting the specified PCI error to the indicated PE 🫶

⭐ SYNOPSIS ⭐

int eeh_pe_inject_err (struct eeh_pe *pe , int type , int func ,
unsigned long addr , unsigned long mask );

like, that's the whole vibe check right there. it returns an int, it takes five things, we move 💅

🦋 ARGUMENTS 🦋

  • pe — the indicated PE. that's the one getting the whole treatment 💖
  • type — error type. which flavor of oops are we serving today 🍓
  • func — error function. the specific function of the error, yk how it is
  • addr — address. where the drama happens 📍
  • mask — address mask. the address's little filter bestie 🌈

🔥 DESCRIPTION 🔥

so the way this works: this routine gets called to inject the specified PCI error — and which error that is? that's decided by type and func, no cap — straight into the indicated PE. and why?? for testing purpose, obviously 💀 like we're stress-testing the thing on purpose, main character energy fr fr.

ngl this is a "poke it and see what happens, but on purpose" situation — it's literally in the description that it's for testing, so don't come for me if you inject an error somewhere you didn't mean to 🙈
