[PATCH 1/4] drm/amdgpu: Add gpu_coredump parameter

Fri Aug 16 07:54:44 UTC 2024


From: Trigger Huang <Trigger.Huang at amd.com>

Add new separate parameter to control GPU coredump procedure. This can
be used to decouple the coredump procedure from gpu recovery procedure

V2: enable gpu_coredump by default (Alex)
