The series is to enable GPU retirement feature, which is trigged when bad pages detected by RAS ECC exceed the threshold value. When the saved bad pages written to eeprom reach the threshold, one ras recovery will be issued immediately and the recovery will fail to tell user that the GPU is BAD and needs to be retired for further check. During bootup, similar BAD GPU check is conducted as well when eeprom get initialized, and it will break boot up for user's awareness. User could set bad_page_threshold=0 when probing amdgpu driver to disable this feature and bring up GPU as usual.
