💅 gmc_v7_0_vm_decode_fault — kernel API manual, but make it cute 🎀

okay so bestie, welcome to the gmc_v7_0_vm_decode_fault(9) page ✨ this one lives in the Kernel API Manual and honestly? it's a little icon and it knows it. the way this function just translates GPU fault register garbage into actual human words? main character energy fr fr 👑

🌸 NAME 🌸

gmc_v7_0_vm_decode_fault — print human readable fault info 💖

like yes, that's the whole job. it takes the scary numbers and turns them into something you can actually read. slay.

🦋 SYNOPSIS 🦋

void gmc_v7_0_vm_decode_fault (struct amdgpu_device *adev , u32 status ,
u32 addr , u32 mc_client , unsigned int pasid );

five arguments, no return value, no cap. it just does the thing and prints 💅

🎀 ARGUMENTS 🎀

  • adev — the amdgpu_device pointer 🫶 your little handle to the whole AMD GPU device situation.
  • status — the VM_CONTEXT1_PROTECTION_FAULT_STATUS register value. yes, all of that. it's the status register, bestie, keep up 😭
  • addr — the VM_CONTEXT1_PROTECTION_FAULT_ADDR register value ✨ the address part of the fault tea.
  • mc_client — the VM_CONTEXT1_PROTECTION_FAULT_MCCLIENT register value. another register value, another day 🌈
  • pasid — debug logging only — no functional use 🙈 literally just there for the logs. it does not do anything else. do not come for it.

💜 DESCRIPTION 💜

Print human readable fault information (CIK). 🔥

that's it, that's the vibe. it takes the fault info and makes it human readable, and the parenthetical is here to tell you this is the CIK flavor specifically 👑 iykyk.

ngl this one is a printer, not a fixer. it's giving "narrator", not "hero" — don't expect it to solve your fault, just to tell you about it 💀
