[patch 00/28] RFC/RFT: Input - sysfs integration

[patch 00/28] RFC/RFT: Input - sysfs integration

[Dmitry Torokhov]

[Argh, resending with subjects and proper CCs]

Hi,

The following set of patches deals with converting input subsystem
to the driver model and intergrate it with sysfs. This allows us
to remove custom-made input hotplug handler and finally have an
option of netlink-only hotplug notifier.

Some changes to the driver core were required. I decided that I did
not want to add an additional class to /sys/class directory; instead
class code was changed to allow nesting several classes. This way
we can have:

/sys/class/input/
|-- devices
|   |-- input0
|   |-- input1
|   `-- input2
`-- interfaces
    |-- event0
    ...
    |-- mouse1
    `-- ts0

and not clutter the top-level directory. Top-level classes define
individual subsystems, lower-level classes define individual parts.
In this particular case 'devices' directory contains class devices
corresponding to input_dev structures whereas 'interfaces' has
class devices produced by input interfaces (handlers), such as
evdev, mousedev, tsdev and joydev.

I believe that other subsystems, such as firewire, SCSI, USB and
I2C could also be moved to a hierarchy of classes to make /sys
tree more organized.

Although all this compatible with pre-udev hotplug scripts I was
advised that having sub-classes will require some changes to udev.

Class interface code was slightly changed to pass interface to
add/remove methods. This way subsystem can have a generic handler
and still call individual interfaces's methods if needed. There are
couple if I2O patches that deal with class interface code, these are
not directly related to this series, but required for compiling.
The maintainer acked them and will push with the rest of I2O
updates.

When registering class devices hotplug event is now sent before
adding interfaces, otherwise children's hotplug events would reach
userspace (udev) first.

The full sysfs input hierarchy on by laptop is the following:
[dtor@core ~]$ tree /sys/class/input/
/sys/class/input/

[patch 01/28] I2O: remove class interface

[Dmitry Torokhov]

[-- Attachment #1: i2o-remove-class-interface.patch --]
[-- Type: text/plain, Size: 11795 bytes --]

I2O: remove i2o_device_class_interface misuse

The intent of class interfaces was to provide different
'views' at the same object, not just run some code every
time a new class device is registered. Kill interface
structure, make class core register default attributes
and set up sysfs links right when registering class
devices.

I've applied this.  I've also cleaned up the class stuff some more and
converted the drivers/message/i2o/iop.c code to use the easier class and
class_device interfaces, as you should not have 2 refcounted structures
trying to control the same overall structure.  The i2o device structure
is still like this and remains to be fixed up.  If no one does it soon,
I'll clean it up too.

thanks,

Could you please wait until i supply the patch, if everyone applies 
patches it's very hard to get those changes and mine together...

And i really don't see that this change is highly critical...

Thank you very much for your understanding...

I2O: cleanup - remove i2o_device_class

I2O devices reside on their own bus so there should be no reason
to also have i2c_device class that mirros i2o bus.

Ok, nice, this is good.  But it doesn't apply at all, somethings odd.
What tree is this diffed against, Linus's or -mm?

methods. This way a subsystem can implement generic add/remove
handlers and then call interface-specific ones.

Ok, I've applied this one, and the other "convert the input drivers to
be dynamic" to my tree, as this is all great work.

I'll work on the last few patches that you have, with regard to how to
tie it into sysfs "properly" now, and get back to you, just wanted to
apply all of these, so we have a common base to work on.

Oh, I did change one thing in this patch:

I made that EXPORT_SYMBOL_GPL().  Let me know if you object to this.

Greg,

Could you please drop these patches for a while? Or maybe just don't
push them to Linus yet. The reason is that I want to change
input_allocate_device to take bitmap of supported events. This way I
could allocate ABS tables dynamically at the same time I allocate
input_dev itself and it will simplify error handling logic in drivers
and it will save I think 1260 bytes per input_dev structure which is
nice. And I don't want to go through all subsystems yet again soI want
to fold into my input dynalloc patch...

How about I hold on to them, until you send me replacements for them?
I'm using quilt so I can just drop them and add your new ones very
easily.  I will not push them to Linus until you and Vojtech say it's ok
for me to do so.

Well, I tried implementing the proposal above and interface came out
pretty awkward to use. My next option is to move abs table into
"->private" structure, much like keytable was moved, or (for HID-like
devices) allocate it when actually needed and adjust individual
drivers. So I guess the patches that you have right now are good after
all.

The problem is that the ->abs tables are accessed in the input core and
in the handlers, too, which means they have to share the lifetime rules
with the input_dev struct itself.

That means we probably have a problem with the drivers deallocating the
keytable, while the device still exists, because there is a reference to
it from say sysfs, and keyboard.c tries to access the keytable because
of an ioctl.

Not necessarily, you just need to make sure that you don't try to access
these fields when input_dev is "half-dead". But we have many issues with
locking/lifetime rules in input core so that's just another item that
needs to be considered.

I wanted to get basic sysfs support in and then work on locking...

... when the first one to fix should be the lifetime rules.  Both sysfs
stuff and locking depend on those...

FWIW for me it is easier to think about lifetime rules when I already have
sysfs support. I mean sysfs itself dictates basic lifetime rules, additional
constraints are just that - additional constraints.

I was planning on getting patch 8 (preparation patch) into kernel ASAP
and then just sending individual subsystem patches to maintainers and
Andrew so they can merge at their leisure (but don't wait for too long
;))

I have no problem with you submitting the changes. If Vojtech is fine
with the proposed way, I would say that we get all of these changes into
mainline now. The device model integration is long overdue.

I'm fine with it, yes. I'm not completely convinced that an input device
is really a class and not a device. ;) But I can understand that view.

They are devices - class devices :). I have the following distinction
in my head - "normal" devices (bus devices) are real hardware devices
and their drivers need to do resource and/or power management. Class
devices represent virtual devices - some kind of abstraction - that
unify and combine "real" devices from several buses into one class.
And of course nothing shoudl stop us from building class devices on
top of other class devices, if needed.

Anyway, I think if Greg gives up and agrees on nesting classes all of
it can go in -mm for now and I will contact other maintainers to
verify that changes work. IIRC video/dvb mainatiners prefered all
changes to go through them.

In any case I don't expect it reach Linus until after 2.6.14 released
- do you agree?

No, I don't agree with this.  Give me a day to write up what I think we
should do instead (something along the lines of "subclasses")

Oh, I agree this isn't 2.6.14 material :)

Hmm.. nested class _is_ a subclass. It is just not a separate object
structure (like you don't have sub-devices either). But I guess I
better wait fro your write-up...

Yes. While input drivers do need to care about power management usually,
the input device abstraction itself doesn't have to, which makes it
indeed a special kind of a device.

I was always wondering whether the distinction between bus/class was
needed, as the border isn't very clear.

Right. They just signal to underlying hardware driver when they are in
use (open), but the actual power management is left to the specific
bus/driver, not input core.

Classes combine devices which are logically the same, i.e. they
perform similar functions. Buses combine devices that are perform
different functions but have similar hardware interface. For example a
network cards - it is a class. You can have network card sit on a PCI,
USB, ISA buses but for the rest of the kernel they are accesses
through netdev abstraction. At least this is my understanding of our
device model ;)

Especially with things like Ethernet - there is not much difference
between it and other busses like SCSI. Both the Ethernet card and the
SCSI card give access to a bus behind them, they're in fact just
bridges.

You can have a harddrive sitting on both SCSI and Ethernet (iSCSI), and
there even is an IP-over-SCSI patch somewhere that allows connecting two
machines with a SCSI cable.

Similarly, you can have USB on PCI and on ISA. There will be two
different USB controllers in different places in the bus hierarchy. Yet
they can be accessed through the same means, something that would make
them a class.

[I'm playing a bit of a devil's advocate here - I see what the
distinction is trying to achieve.]

[patch 25/28] input core: implement class hierachy

[Dmitry Torokhov]

[-- Attachment #1: input-subclass.patch --]
[-- Type: text/plain, Size: 19208 bytes --]

Input: create 'input' class hierarchy

Make 'input' a root class and add 'devices' and 'interfaces'
subclasses. 'devices' subclass will contain input_dev class
devices whereas 'interfaces' will have devices created by
input handlers, such as evdev, mousedev, etc.

[patch 26/28] input core: remove custom-made hotplug handler

[Dmitry Torokhov]

[-- Attachment #1: input-sysfs-hotplug.patch --]
[-- Type: text/plain, Size: 9772 bytes --]

Input: remove custom-made hotplug handler

Now that all input devices are registered with sysfs we can remove
old custom-made hotplug handler and crate a standard one.

do you have a GIT tree with all that changes that I can simply pull in
for testing?

Not yet, but I think I will set one up if there is a general approval
of the direction of the series.

The absfuzz initialisation in kbtab_probe() got lost.

Looks fine here:

+       input_set_abs_params(input_dev, ABS_X, 0, 0x2000, 4, 0);
+       input_set_abs_params(input_dev, ABS_X, 0, 0x1750, 4, 0);
                                                         ^^^

Is there something in your tree that not in Linus's yet?

Oh.  You mean they replace these?

-	kbtab->dev.absfuzz[ABS_X] = 4;
-	kbtab->dev.absfuzz[ABS_Y] = 4;

Not a step forward in readability?

Yeah, some stuff, that's why I noticed.

Depends... It's much more compact so quite often you can see entire
device specification on one screen which is nice IMHO. Just remeber
"min, max, fuzz, flat" ;)
