💅 amdgpu_vm_handle_fault(9) — Kernel API Manual ✨

okay so bestie, we're deep in the kernel today and the page we're vibing with is amdgpu_vm_handle_fault(9). yes that's a mouthful, no we're not scared of it 🫶

🌸 NAME 🌸

amdgpu_vm_handle_fault — graceful handling of VM faults 💖

like, when the VM trips and falls, this function catches it. gracefully. iconic behaviour honestly.

✨ SYNOPSIS ✨

bool amdgpu_vm_handle_fault (struct amdgpu_device *adev , u32 pasid ,
       u32 vmid , u32 node_id , uint64_t addr , uint64_t ts , bool write_fault
       );

it returns a bool, bestie. remember that, it's gonna matter in a sec 👀

🎀 ARGUMENTS 🎀

  • adev — the amdgpu device pointer. your main character device, fr fr.
  • pasid — the PASID of the VM. its little ID badge 🪪
  • vmid — the VMID. heads up: only used for GFX 9.4.3. everywhere else it's just sitting there being decorative 💅
  • node_id — the node_id received in the IH cookie. only applicable for GFX 9.4.3, so same energy — niche but valid 🍓
  • addr — the address of the fault. where the drama went down 📍
  • ts — the timestamp of the fault. for the record, for the receipts ⏰
  • write_fault — true means it's a write fault, false means it's a read fault. binary queen 👑

🦋 DESCRIPTION 🦋

so the whole point: try to gracefully handle a VM fault. that's it, that's the vibe 🧚

it returns true if the fault was handled and shouldn't be reported any more. so like — if you get a true back, the situation is handled, we are NOT reporting it again, move on, nothing to see here 💀

ngl the "graceful" part is doing a lot of work in that sentence — this function's whole personality is not making a scene about a fault ✨

🌈 SEE ALSO 🌈

the whole friend group, in kernel file ./drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c, plus:

like yes that's a long list but they're all important, don't skip them, i'm serious 😭🫶

and that's the page, bestie! this one lives at ./drivers/gpu/drm/amd/amdgpu, dated October 2026, under the name amdgpu_vm_handle_fault(9) — slay, go handle some faults gracefully, periodt 💜🌟
