Yes, the same was tested using devlink health test interface by injecting errors.
The dump gets generated automatically and the counters do get out of sync,
in case of continuous error.
That wouldn't be much of an issue as the user could manually trigger a dump clear and
Re-dump the counters to get the exact status of the counters at any point of time.

Now that recover op is added the devlink error counter and recover counter will be
proper. The internal counter for each event is needed just to understand within a specific reporter, how
many such events occurred.
Following is the log snippet of the devlink health test being done on hw_nix reporter.
# for i in `seq 1 33` ; do devlink health test pci/0002:01:00.0 reporter hw_nix; done
//Inject 33 errors (16 of NIX_AF_RVU and 17 of NIX_AF_RAS and NIX_AF_GENERAL errors)

Also, note that auto_dump is something which can be turned off by user.
# devlink health set pci/0002:01:00.0 reporter hw_nix auto_dump false
So that user can dump whenever required, which will always return the correct counter values.

for 250 error injections)

I thought it'd be better to just add each error as its own reporter
rather than combining them and abusing context for reporting detailed
stats.
This seems to be harder to get done than I thought. Maybe just go back
to the prints and we can move on.

Why the weird date? Is this something on your system?

You seem to have missed the feedback Saeed and I gave you on v2.
Did you test this with the errors actually triggering? Devlink should
store only one dump, are the counters not going to get out of sync
unless something clears the dump every time it triggers?

Add health reporters for RVU NPA block.
NPA Health reporters handle following HW event groups
- GENERAL events
- ERROR events
- RAS events
- RVU event
An event counter per event is maintained in SW.
Output:
# devlink health
pci/0002:01:00.0:
reporter hw_npa
state healthy error 0 recover 0
# devlink health dump show pci/0002:01:00.0 reporter hw_npa
