The first patch creates a new module parameter to disable soft recoveries, ensuring every recovery go through the full device reset, making easier to generate resets from userspace tools like [0] and [1]. This is important to validate how the stack behaves on resets, from end-to-end. The second patch is a small addition to mark guilty jobs that causes soft recoveries for API consistency. The last patches are a rework to store more information at devcoredump files, making it more useful to be attached to bug reports. The new coredump content look like this: **** AMDGPU Device Coredump **** version: 1 kernel: 6.4.0-rc7-tony+ module: amdgpu time: 702.743534320 process_name: vulkan-triangle PID: 4561 IBs: [0] 0xffff800100545000 [1] 0xffff800100001000 ring name: gfx_0.0.0 Due to nested IBs, this may not be the one that really caused the hang, but it gives some direction.
