Different vendors have different error sets defined by Hardware. If we always define the new bits when we cannot find an exact 1:1 mapping in the core the 64 bits would soon be used out. Also, it's hard to understand the mixture of different error sets. To address these issues updated the status interface to handle the vendor-specific messages in a generic way. With the updated status interface the vendor-specific driver files can independently handle the error messages.I think we don't have to provide the vendor specific HW errors in a generic way, maybe the vendor specific drivers could handle them by its own device attributes. Since the output value set of the interface is specific to each driver, users should still interpret them in specific manners. So doesn't see much value for a class interface.
Agree, vendor specific drivers could handle them by its own device attributes. If it is the case, can we remove the existing status interface relevant changes from the core?
