[Qemu-devel] [PATCH 01/23] usb-hid: simplify class initialization a bit

[Qemu-devel] [PATCH 01/23] usb-hid: simplify class initialization a bit

[Anthony Liguori]

We can probably model USBHidDevice as a base class to get even better code
sharing but for now, just use a common function to initialize the common class
members.

NACK. This introduces broken code, see below.

Minor nit: I'd find object_class_by_name(name) != NULL easier to read
than double negation.

...and this is broken, as pointed out before:

http://patchwork.ozlabs.org/patch/138396/

Easiest would be to reorder 11/23 before this one so that we don't
introduce a broken, bloated user of foreach in the first place.

Otherwise looking good.

[Qemu-devel] [PATCH 08/23] qdev: register all types natively through QEMU Object Model

[Anthony Liguori]

This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

Can you document this process in enough detail so that those of us with
trees/branches not yet upstream can use it to ease the process of
rebasing after this lands, please?

Replace DeviceInfo with TypeInfo, mapping:

TypeInfo::name = DeviceInfo::name
TypeInfo::parent = subclass argument to qdev_register_subclass
TypeInfo::instance_size = DeviceInfo::size
TypeInfo::class_init = DeviceInfo::class_init

Any remaining DeviceInfo members being initialized should be moved to the 
class_init function as assignment to DeviceClass.  Use DEVICE_CLASS() to case 
the ObjectClass in the argument to DeviceClass *dc and then assign the members.

Replace qdev_register_subclass calls with type_register_static.

Regards,

Anthony Liguori

It is no longer used in the tree since everything is done natively through
QEMU Object Model.

[Qemu-devel] [PATCH 10/23] qdev: remove baked in notion of aliases

[Anthony Liguori]

Limit them to the device_add functionality.  Device aliases were a hack based
on the fact that virtio was modeled the wrong way.  The mechanism for aliasing
is very limited in that only one alias can exist for any device.

We have to support it for the purposes of compatibility but we only need to
support it in device_add so restrict it to that piece of code.

Yes, because s390 doesn't have PCI.

Please change this to a table so that you can have:

     if (object_class_by_name(table[i].name) &&
         strcmp(alias, table[i].alias) == 0) {
         return table[i].name;
     }

and for the other direction

     if (object_class_by_name(table[i].name) &&
         strcmp(name, table[i].name) == 0) {
         return table[i].alias;
     }

If you reordered this patch before 07/23 then you could apply it right
away, unbreaking object_class_foreach().

[Qemu-devel] [PATCH 12/23] qom: add new command to search for types

[Anthony Liguori]

This adds a command that allows searching for types that implement a property.
This allows you to do things like search for all available PCIDevices.  In the
future, we'll also have a standard interface for things with a BlockDriverState
property that a PCIDevice could implement.

This will enable search queries like, "any type that implements the BlockDevice
interface" which would allow management tools to present available block devices
without having to hard code device names.  Since an object can implement
multiple interfaces, one device could act both as a BlockDevice and a
NetworkDevice.

[Qemu-devel] [PATCH 14/23] qdev: refactor away qdev_create_from_info

[Anthony Liguori]

Note that the FIXME gets fixed in series 4/4.  We need to convert BusState to
QOM before we can make parent_bus a link.

[Qemu-devel] [PATCH 16/23] qdev: nuke qdev_init_chardev()

[Anthony Liguori]

I'm sure the intentions were good here, but there's no reason this should be in
qdev.  Move it to qemu-char where it belongs.

[Qemu-devel] [PATCH 17/23] qom: move properties from qdev to object

[Anthony Liguori]

This is mostly code movement although not entirely.  This makes properties part
of the Object base class which means that we can now start using Object in a
meaningful way outside of qdev.

Re: [Qemu-devel] [PATCH 17/23] qom: move properties from qdev to object

Can we move them to an intermediate base class?  I would like to use QOM 
refcounting for other objects, such as SCSIRequest, so it is important 
to have Object as a pretty light-weight class.  Also (and perhaps more 
importantly), interface implementations are Objects too and they do not 
need properties.

I cannot think of any better name than IntrospectableObject, which is 
quite a mouthful.  I suppose that we could have the base class but still 
pass the objects to the function as Object * and use the OBJECT macro.

I'm just not sure how I feel about this.

The overhead of properties are small in terms of object size.  It's just 
sizeof(void *).

I think that read-only properties could be interesting for SCSIRequest.  For 
instance, I can imagine having SCSIRequest is-a BlockRequest and having an error 
property associated with it.  That would provide a nice way to have an info io 
operation that returned a list of failed I/O requests or something like that.

SCSIRequests can have a BlockRequest as a child; not all SCSIRequests 
have I/O attached to them, but I see the general concept.  I'm not sure 
we'll be able to optimize enough, but we can certainly try...

[Qemu-devel] [PATCH 18/23] qom: accept any compatible type when setting a link property

[Anthony Liguori]

Links had limited utility before as they only allowed a concrete type to be
specified.  Now we can support abstract types and interfaces which means it's
now possible to have a link<PCIDevice>.

[Qemu-devel] [PATCH 21/23] object: sure up reference counting

[Anthony Liguori]

Now we have the following behavior:

1) object_new() returns an object with ref = 1
2) object_initialize() does not increase the reference count (ref may be 0).
3) object_deref() will finalize the object when ref = 0.  it does not free the
   memory associated with the object.
4) both link and child properties correctly set the reference count.

The expected usage is the following:

1) child devices should generally be created via object_initialize() using
   memory from the parent device.  Adding the object as a child property will
   take ownership of the object and tie the child's life cycle to the parent.

2) If a child device is created via qdev_create() or some other form of
   object_new(), there must be an object_delete() call in the parent device's
   finalize function.

We might want to fix this by adding a special "created as child" 
refcount value, so that the object_delete can still be automatic. 
Adding floating references as they have them in GObject is also 
possible.  I agree that it can be left for later, though.

After a few weeks of repetitive code conversion and rebasing the same series a 
million and a half times, I'm surprised I'm not speaking entirely in tongues :-)

Given that object.c is GPLv2+, I've sticked with that license myself;
but was that choice of license intentional? Effectively means we can't
really have any liberally-licensed device emulation. (But same holds for
MemoryAPI.)

Actually you can.  It's the combination that cannot be released 
liberally, but that's already the case without QOM or MemoryRegion.

If somebody wishes to port such a module to a proprietary platform 
(which doesn't have QOM or other GPL bits), they can.

This needs to be carefully merged back but I'm not 100% confident the problem is
solved by this commit.

[Qemu-devel] [PATCH 00/23] qom: use Type system to register all devices

[Anthony Liguori]

(Sorry for not posting this correctly, I didn't want to spam the list with a 
second submission)

This is the 3rd QOM series.  I decided to post this even though there's a known 
issue with device_del as I wanted to give people more time to review what's 
going on here.

The goal of this series is to make DeviceState a first class QOM base class. 
The result is that you can object_new(TYPE_E1000) and have a functioning device. 
  qdev_create() and qdev_free() are now trivialized as QOM wrappers.

Patch 8/23 is an automated touch everything patch.  I decided to leave it as one 
big patch because this is entirely programmatic.  There's no intelligence in 
this patch so I think it's easier to review quickly as one big change.

The other notable feature of this series it that properties have been moved to 
the Object base class.  This means that other subsystems can begin using QOM.

This is the last touch every file in the tree series.

Re: [Qemu-devel] [PATCH 00/23] qom: use Type system to register all devices

I think the "lingering issue with device_del" is that my broken battery is 
causing my laptop to overheat...  So I'll fold patch 23 into the right spot and 
repost tomorrow.

Could use another set of eyes to walk through the reference counting stuff 
though.  It's a bit nastier than I would like it to be.  I really dislike the 
notion of having an object_unparent in the unplug path.

Re: [Qemu-devel] [PATCH 00/23] qom: use Type system to register all devices

It's kind of awkward having a patch series that is both long (number
of patches) and wide (patches that require touching/conversion of
every device in the tree), because the length means it needs a long
review time on the list, and the width means it's going to conflict
with lots of other changes (and especially newly arriving device
models).

I could certainly split this into three parts.

But patches 0-8 aren't terribly meaningful outside of the context of patch 9.

And patch 9 by itself leaves the old infrastructure around which means that you 
would potentially need more patches like patch 9 in a future series.

So I don't think this series could really be trimmed by anything more than a 
couple patches and I don't see a huge advantage in doing that.

This sort of changes are the exception, not the common thing.  Once this series 
is merged, things will go back to normal patch series wise.
