amdgpu_gfx_h...e_priv_fault(9)

💖 NAME 💖

okay so bestie, you're looking at the amdgpu_gfx_h...e_priv_fault(9) page from the Kernel API Manual ✨ — and the main character is amdgpu_gfx_handle_priv_fault, the function that handles privileged instruction faults. 💅

✨ SYNOPSIS ✨

void amdgpu_gfx_handle_priv_fault (struct amdgpu_device *adev , struct
amdgpu_iv_entry *entry , u8 me_id , u8 pipe_id , u8 queue_id );

that's the whole signature, bestie — copy it exactly, no cap. 🫶

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. the device itself, periodt. 💻
• entry — the interrupt vector entry that contains the fault information. the tea is in here ☕
• me_id — micro-engine ID of the faulty ring. 🌀
• pipe_id — pipe ID of the faulty ring. 🧚
• queue_id — queue ID of the faulty ring. 🎯

💅 DESCRIPTION 💅

okay so this function handles privileged instruction faults. it does the detective work to identify the faulty ring — which can be gfx or compute, no cap — and then it triggers a scheduler fault, or it recovers the faulting user queue. basically: identify the messy ring, then either scheduler-fault or recover the user queue. periodt. 💖
