This patchset implements a request made by Xaver Hugl about wedge events: "I'd really like to have the PID of the client that triggered the GPU reset, so that we can kill it if multiple resets are triggered in a row (or switch to software rendering if it's KWin itself) and show a user-friendly notification about why their app(s) crashed, but that can be added later."
>From >https://lore.kernel.org/dri-devel/CAFZQkGwJ4qgHV8WTp2=svJ_VXhb-+Y8_VNtKB=jlsk6dqmy...@mail.gmail.com/ This patchset depends on https://lore.kernel.org/dri-devel/20250225010221.537059-1-andrealm...@igalia.com/ For testing, I've used amdgpu's debug_mask options debug_disable_soft_recovery and debug_disable_gpu_ring_reset to test both wedge event paths in the driver. To trigger a ring timeout, I used this app: https://gitlab.freedesktop.org/andrealmeid/gpu-timeout Thanks!
