gmc_v8_0_vm_decode_fault(9)

🌸 NAME 🌸

okay so this is the gmc_v8_0_vm_decode_fault(9) page from the Kernel API Manual, and we are literally here for gmc_v8_0_vm_decode_fault — the function whose whole thing is: print human readable fault info. That’s the vibe. 💅✨

---

✨ SYNOPSIS ✨

void gmc_v8_0_vm_decode_fault (struct amdgpu_device *adev , u32 status ,
       u32 addr , u32 mc_client , unsigned int pasid );

the way this takes five arguments and returns void… very demure, very kernel-coded. 🎀

---

🎀 ARGUMENTS 🎀

• adev — amdgpu_device pointer. bestie, it’s the device pointer. 🫶
• status — VM_CONTEXT1_PROTECTION_FAULT_STATUS register value. yes, that exact register, no cap. ⭐
• addr — VM_CONTEXT1_PROTECTION_FAULT_ADDR register value. the address register value, slay. 🦋
• mc_client — VM_CONTEXT1_PROTECTION_FAULT_MCCLIENT register value. another exact register value, we love a consistent queen. 💜
• pasid — debug logging only - no functional use. literally just for debug logging, not functional use. 🙈

---

💖 DESCRIPTION 💖

It prints human readable fault information (VI). iconic behavior, honestly. 💅🔥
