Enough with this debugfs madness.

Expose this stuff through standard interfaces.

They are simple statistics for crying out loud!

I'm not applying this, and I'm really getting irritated about how much
garbage people put into debugfs when it has _NO_ business being there.

Sorry.

They are simple statistics. But they does not fit into any existing
interface. This is about EMAD packets. They are not per-netdevice, but
per-pcidevice. So I cannot put them into ethtool.

I see no other iface to expose this other than debugfs. Please suggest
some other way, I don't see it :/

Thanks.

I think that is the primary purpose of this iface, To put arbitrary
debugging garbage there. Am I missing something?

Then create one, instead of crapping up the driver with debugfs
craziness.

It's not garbage if it's useful for someone.

If it's not useful, why even bother?

This is why I hate debugfs, it's a fundamentally flawed facility.

I'm not sure it is possible to come up with a generic interface for
arbitraty statistics for some generic PCI device.

I can imagine the pushback saying "hey, put that statistics into subtree
specific area, like netdev etc". And that is correct. In vast majority
of cases, that can be done.

In mlxsw case however, 36 netdevices are sharing 1 pci device. And the
stuff related to that pci device cannot be exposed via netdev.

I don't think that are much more cases like this. Therefore I think that
for this cases, debugfs might be a good way to expose debugging stats.

Scott wanted to do similar things in rocker.  DSA guys too.

Every switch device is going to have some kind of hierarchy like
this, it's not a unique situation.

So I don't buy the "this is a special situation" thing at all.

We've been able to get buy so far without a user-visible device for
the switch.  The switch ports are represented by netdevs, so that's
easy.  How can we create an object for the switch itself, so we can
attach common interfaces for the user to dump switch-level stats or
tables?   Using another netdev doesn't seem right.  Do we need a new
device class for switches, and then create some common tool/interfaces
for switch device class?

I agree this is something crucially missing. If we try to list what
could be missing currently, there is mostly:

* switch-wide statistics, tables, databases
* controlling a firmware agent running on the switch
* restarting/re-configuring the switch hardware

All of these already have proper ethtool control interfaces, so using
something that understands a specialized net_device might be the easiest
way to go, but we would need a way to put it in the non network device
name space so tools and users to do not get confused?

We could also have a specific SET_NETDEV_DEVTYPE() which helps make that
specific device be part of a "switch-mgmt" class for instance?

This is probably what we will need to do.

There has also been a discussion lately about making light weight
netdev objects, of which these new switch things can be a super-class
of.

Switch object itselt would not help you to expose rocker internals. I
don't think that you can find generic way, same for all drivers, to
expose internal tables and stuff. That is hw specific.

Tables are datastructures with names and types.

Is it not possible to describe datastructures and their types with
user visible interfaces?

Anyone against what I am saying right now is simply lazy.

I'm not saying it is not possible, it certainly is. But I think that for
example rocker internals have no value to default user, he should not
care and he cannot find out what is going on there without knowledge or
rocker.c code. The question is, do we need some standard interface to
expose random debugging data? I don't think so, I think that debugfs is
exactly the tool to be used in that case.

If it is only interesting to rocker.c maintainer, he can keep a local
patch he applies when he needs such a facility.

This discussion is becomming circular.

If it's useful, it needs a well defined interface.

If it's not useful, it doesn't belong in the tree.

Therefore, debugfs is useless.

Late reply, sorry, but another idea is to leave the stats in place (as
they were going to be calculated even with debugfs unmounted) and (for
now at least) fetch them with systemtap, perf or something like that.
Then the stats are there for when you need them and with an interface as
flexible as it can get. Even if you happen to do a post-mortem analysis,
the info would at least be there.
