[PATCH v4 5/5] drm/amdgpu: do not resume device in thaw for normal hibernation

2025-07-08 Thread Samuel Zhang
For normal hibernation, GPU do not need to be resumed in thaw since it is not involved in writing the hibernation image. Skip resume in this case can reduce the hibernation time. On VM with 8 * 192GB VRAM dGPUs, 98% VRAM usage and 1.7TB system memory, this can save 50 minutes. Signed-off-by: Samu
