During gpu reset, all GPU-related resources are
inaccessible. To avoid affecting ras functionality,
suspend ras module before gpu reset and resume
it after gpu reset is complete.
V2:
Rename functions to avoid misunderstanding.
V3:
Move flush_delayed_work to amdgpu_ras_process_pause,
Move schedule_delayed_work to amdgpu_ras_process_unpause.
V4:
Rename functions.
V5:
Move the function to amdgpu_ras.c.

drm/amdgpu: Improve ras fatal error handling function2025-10-20T22:18:35+00:00YiPeng ChaiYiPeng.Chai@amd.com2025-07-21T07:14:03+00:00urn:sha1:408bd841ad24fd9891a1cd9ca11cf4f48d9667dc
In multi-gpu case, a fatal error will generate several
fatal error interrupts. After improving this function,
the ras module can reuse this function to only
handle the first interrupt.
V3:
Initialize event_id using RAS_EVENT_INVALID_ID.
