In the present series it registers only one genl family per device, but genl framework shouldn't impose any restriction on multiple family registration as along as the family names are unique, but what is the purpose of it?
for the second part of the question IIUC an error can have different severity, like hbm-ss0-0 can be of fatal or non fatal, so then we could have two entries
for each like how it is done in this series for the same error type which can have different severities, so for hbm-ss0-0 it would enumerate error-gt0-soc-fatal-hbm-ss0-0
and error-gt0-soc-nonfatal-hbm-ss0-0 counters as our HW reports both of these kinds.
Also, to highlight the error management is left to the driver, the drm_netlink doesn't handle any of those it just reports whatever the driver exposes.
please let me know if I didn't get your question right.
Thanks,
Aravind.

Mixing severity and error type in a single array may not be the best practice. for example, error-gt0-soc-fatal-hbm-ss0-0 might be converted to non-fatal or deferred error, so driver doesn't need to be response immediately.
