Abstract
A processing device in a host system detecting a failure of a memory sub-system coupled to the host system and collects debug information from the memory sub-system via a memory sub-system interface. Responsive to determining that the debug information is not sufficient to correct the failure of the memory sub-system, the processing device performing an authentication process to authenticate the system to the memory sub-system, collects enhanced debug information from the memory sub-system via the memory sub-system interface, and performs one or more corrective actions based on the enhanced debug information to correct the failure of the memory sub-system.
Claims20
A memory sub-system comprising:
- a memory sub-system interface;
- and
- a processing device, operatively coupled with the memory sub-system interface, to perform operations comprising:
- receiving a request from a requestor for debug information related to a failure of the memory sub-system;
- providing the requested debug information to the requestor via a memory sub-system interface;
- receiving a request from the requestor for enhanced debug information related to the failure;
- determining whether the requestor has been properly authenticated;
- and
- responsive to determining that the requestor has been properly authenticated, providing the requested enhanced debug information to the requestor via the memory sub-system interface.
A method comprising:
- receiving a request from a requestor for debug information related to a failure of a memory sub-system;
- providing the requested debug information to the requestor via a memory sub-system interface;
- receiving a request from the requestor for enhanced debug information related to the failure;
- determining whether the requestor has been properly authenticated;
- and
- responsive to determining that the requestor has been properly authenticated, providing the requested enhanced debug information to the requestor via the memory sub-system interface.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- receiving a request from a requestor for debug information related to a failure of a memory sub-system;
- providing the requested debug information to the requestor via a memory sub-system interface;
- receiving a request from the requestor for enhanced debug information related to the failure;
- determining whether the requestor has been properly authenticated;
- and
- responsive to determining that the requestor has been properly authenticated, providing the requested enhanced debug information to the requestor via the memory sub-system interface.
