Asynchronous Event Reporting

Asynchronous Event Reporting

[Michael Heinz]

I'd like to do a quick sanity check here...

I've been asked to make sure I support async event reporting in the 
driver I'm working on (which will eventually be GPL! Honest! :-P).

 From reviewing the code in 2.4 scsi/drivers it appears that the best I 
can do is log that I got the event, but then ignore it - sd.c does not 
support AER.

Is this correct?

Hi,

is there any transfer mechanism which allows an HBA driver to push
its AER data to the mid layer?

Mit freundlichen Grüßen / with kind regards

Well, the fact that no one has answered either one of us would indicate
that, no, there is no way to pass AER data to the mid layer...

Now, where is that clue? I know I had one a minute ago....

Michael,
Yes I believe you are correct.

Sounds like an interesting challange, though.

LoL. Yup. Looks like a real "opportunity to excel" :-P

Seriously, from the current structure of the code I think anything doing
with AER would  be a major hack. It probably makes more sense to hold
off and deal with it as part of a complete rework of the scsi drivers.
