Error reporting for non-volatile memory modules

A method, comprising:

• receiving a plurality of memory access requests including volatile memory reads, volatile memory writes, non-volatile memory reads, and non-volatile memory writes;
• placing memory access commands for fulfilling the memory access requests in a memory interface queue and transmitting the memory access commands from the memory interface queue to a memory channel coupled to a non-volatile storage class memory (SCM) module;
• based on information received over the memory channel, identifying error conditions associated with the memory channel;
• mapping the error conditions from a first number of possible error conditions associated with the non-volatile SCM module to a second, smaller number of virtual error types for reporting to an error monitoring module of a host operating system, the mapping based at least on a classification that the error condition will or will not have a deleterious effect on an executable process running on the host operating system.

A data processing system, comprising:

• a central processing unit;
• a data fabric coupled to the central processing unit;
• and
• a memory controller coupled to the data fabric for fulfilling memory access requests made through the data fabric, the memory controller comprising:
• a command queue having a first input for receiving memory access commands including volatile reads, volatile writes, non-volatile reads, and non-volatile writes, and an output, and having a plurality of entries;
• a memory interface queue having an input coupled to the output of the command queue, and an output for coupling to a non-volatile storage class memory (SCM) module;
• a non-volatile error reporting circuit operable to identify error conditions associated with the non-volatile SCM module and map the error conditions from a first number of possible error conditions associated with the non-volatile SCM module to a second, smaller number of virtual error types for reporting to an error monitoring module of a host operating system, the mapping based at least on a classification that the error condition will or will not have a deleterious effect on an executable process running on the host operating system.
