[Tao] add warning? Or you can add it in amdgpu_ras_mark_ras_event.
[Kevin]:
Thanks suggestion, I will update v2 and add a warn log in function internal.

[Tao] I don't think it's necessary to mark it both in amdgpu_ras_interrupt_poison_consumption_handler and here.
Another question is, event_interrupt_poison_consumption_v9 is used by several ASICs, are you sure the event id code doesn't affect old ASICs?
[Kevin]:
The event id is only used for format the RAS event log, and it won't affect the code logic for old Asics.
