The commands used seems very limited. In AMD SOCs, IP blocks, instances
of IP blocks, block types which support RAS will change across generations.
This series has a single command to query the counters supported. Within
that it seems to assign unique ids for every combination of error type,
IP block type and then another for each instance. 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.
For ex: to get HBM errors, it looks like the current patch series
supports READALL which dumps the whole set of errors. 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.
It would be better if the command argument format can be well defined so
that it can be queried based on IP block type, instance, and error types
supported (CE/UE/fatal/parity/deferred etc.).
