Not sure how good this kind of approach is for an end user. The Ids won't necessarily the stay the same across multiple generations. Users will generally be interested in specific IP blocks.

The query is used to know what all errors exists on a platform and userspace can process the IDs of IP block of interest. I believe even if we list block wise a query will be needed without which userspace wouldn't know which blocks exist on a platform.

What I meant is - assigning an id for every combination of IP block/ 
instance number/error type is not maintainable across different SOCs.

Instead, can we have  something like -
	Query -> returns IP block ids, number of instances, error types 
supported by each IP block.
	Read Error -> IP block id | Instance number /Instance ALL | Error type 
id/Error type ALL.

Or, users have to figure out the ids of HBM stack instance (whose capacity can change depending on the SOC and within a single family multiple configurations can exist) errors and do multiple READ_ONE calls. Both don't look good.

Also, listing individual errors helps if userspace wants to read a particular error at regular intervals. The intention is also to keep KMD logic simple, userspace can build required model on top of flat enumeration.
