Hi!

A driver for the HP iLO/iLO2 management processor, which allows
userspace programs to query the management processor. Programs can
open a channel to the device (/dev/hpilo/dXccbN), and use this to
send/receive queries.

What kind of queries? Is there documentation somewhere?

Generally, it can get data out of the management processor - things
like basic iLO configuration (users, nic, etc), handle SNMP traffic,
flashing iLO, and some others.

Unfortunately, there isn't yet any available documenation.

Ok, I guess we should have documentation "what does it do" and "what
protocol does it speak" before we can think about merging.

I really hope that isn't the case.

The message packets and documention are owned by hardware teams,
and they currently do not want to make that documentation public.

umm, by merging the code a you reveal a lot of what they are attempting to keep secret. what's to stop someone from reading the code and writing the documentation?

that really should be someone at HP if you don't want to publish the exising documentation (since you are submitting the code)

However, I do think there is value in merging the driver without docs.
Having drivers in tree is often stated as a goal, because of the obvious
security and API/ABI disadvantages to out of tree drivers.

If this can't be merged, then we continue to ship an out of tree driver,
which no one (us, distros, customers) likes. We pester our partners to
support this driver, or include it, or what have you. We get slowly
out of date, and bugs creep in, or our package breaks on upstream kernels.
To me, it seems like merging the driver is the better path.

correct, it's a far better path for you and your users, but it gets even better if there is some documentation to go with it.
