Hardware unit for reverse translation in a processor

A method comprising:

• detecting a trigger condition associated with reverse translation, wherein the trigger condition comprises at least one selected from a system start-up, a reboot, a request from an operating system, a request from platform firmware, a request from a driver, and a user command;
• in response to detecting the trigger condition:
• determining, by a reverse translation circuit included in a processor, a module address of a corrupt portion of a memory module;
• determining, by the reverse translation circuit, a range of system physical address (SPA) addresses associated with the memory module;
• performing, by the reverse translation circuit, a plurality of iterations based on the range of SPA addresses, each iteration comprising:
• translating a unique SPA address into a translated module address;
• and
• in response to a determination that the translated module address matches the module address of the corrupt portion of the memory module, identifying the unique SPA address as a current address of the corrupt portion of the memory module.

A system comprising:

• a processor comprising a plurality of processing engines and a memory controller, the memory controller to:
• read, from a non-volatile storage included in a memory module, a module address of a corrupt portion of a memory module;
• and
• determine a plurality of system physical address (SPA) addresses associated with the memory module;
• translate the plurality of SPA addresses into a plurality of translated module addresses, wherein a mapping between the plurality of SPA addresses and the plurality of translated module addresses is changed by one or more system events;
• determine whether a first translated module address of the plurality of translated module addresses matches the module address of the corrupt portion of the memory module, wherein the first translated module address was translated from a first SPA address;
• and
• in response to a determination that the first translated module address matches the module address of the corrupt portion of the memory module, identify the first SPA address as a current address of the corrupt portion of the memory module;
• and
• a system memory coupled to the processor.
