Hi,
This patch is a repost of the patch series posted last friday.
What is in there?
First the qdev property rework. Quite big one, but as it puts the way
properties work upside down it can hardly be split into smaller pieces.
Support for property default values added since I posted it last time.
The patch description is much better too. Otherwise it is unchanged.
The other patches are building on top of the properties. They are a
bunch of little, self-contained and friendly patches. They bring:
* A new, generic -device switch to add devices to your VM.
* Support for attaching user-specified ids to devices.
* A few more devices being switched to qdev.
v2 brings some minor changes:
* rebased, resolved some conflicts.
* picked up the *_dev name convention for bus_info methods.
* folded in the two incremental fixes posted earlier this week.
cheers,
Gerd

This patch is a major overhaul of the device properties. The properties
are saved directly in the device state struct now, the linked list of
property values is gone.
Advantages:
* We don't have to maintain the list with the property values.
* The value in the property list and the value actually used by
the device can't go out of sync any more (used to happen for
the pci.devfn == -1 case) because there is only one place where
the value is stored.
* A record describing the property is required now, you can't set
random properties any more.
There are bus-specific and device-specific properties. The former
should be used for properties common to all bus drivers. Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.
Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties. A few common property
types have PropertyInfos defined in qdev-properties.c. Drivers are free
to implement their own very special property parsers if needed.
Properties can have default values. If unset they are zero-filled.

Use it for the new -device and for the -usbdevice and -bt switches.

no_user: prevent users from adding certain devices.
desc: description of the device.
alias: to allow user friendly shortcuts on the command line, i.e.
-device usbmouse instead of -device "QEMU USB Mouse" or
-device lsi instead of -device lsi53c895a

Add id field to DeviceState. Make qdev_device_add() fill it if supplied
on the command line (i.e. -device foo,id=bar). Make "info qtree" print it.
This helps users and management apps identifying devices in monitor
output, which is especially useful with otherwise identical devices
such as two virtio disks.

With that patch applied "-balloon virtio,args" becomes a shortcut for
"-device virtio-balloon-pci,args".
Side effects:
- ballon device gains support for id=<tag>.
- ballon device is off by default now.
- initialization order changes, which may in different pci slot
assignment depending on the VM configuration.

I think this is going in the wrong direction. The device tree provides us with
a standard way of identifying which bus to add a device to. We should be
removing uses of pci_create, not adding new ones.

Why?
There are properties which tend to be specified as decimal numbers
(counts, sizes, ...) and some which tend to be specified in hex
(adresses, ioports, ...). I think it is useful to have separate
parse/print functions for them, although they both end up being an uint32_t.

I think I can make defval a string instead, then go through
PropertyInfo->parse(). OK?

It checks the size. Which will miss some type mismatches. I'll fix it.

It can fail if the size check (soon to be type check) mentioned above
failed. Such a failure would be a clear qemu bug though, so maybe
abort() instead?

I think this is the wrong distinction. Whether you specify something in hex or
decimal (or even binary/octal) is personal user preference. Distinguishing
between integers and addresses may make sense, as those actually have
different types.

I don't think that's really any better. I guess it may just be something we
have to put up with. Possibly have a helper macro that sets all the fields.
Something like:
.properties = (Property[]) {
DEFINE_PROPERTY_UINT32("fifo-size", SyborgPointerState, fifo_size, 16)
}
Ideally we'd have a single DEFINE_PROPERTY macro and the type would be figured
out from typeof(fifo_size), but I can't think how to do that.

Yes. Returning a status code then never checking it is completely pointless.

Hmm. hex32 will accept/print hex numbers only. uint32 should accept
0x<hexnumber> though. I'll double-check it actually does.

I'll have a look whenever I can work out some macro+typeof magic. Would
be great if we can catch type mismatches at compile time.

Why?
Let me guess: Because pci bus numbers are guest-changeable and thus not
stable?
How about using user-specified ids to specify busses then?
PCI example:
instead of -device $name,addr=$bus:$slot.$fn
use -device $name,bus=root,addr=$slot.$fn
SCSI example:
host adapter: -device lsi,id=foo
scsi disk: -device scsi-disk,bus=foo,addr=$lun

Because I don't think this code need to be bus specific.

I was thinking something a bit more like
-device lsi,bus=/i440fx/pci
-device scsi-disk,bus=/i440fx/pci/lsi/scsi
This example is maybe slightly unclear because the i440fx and lsi child busses
happen to be called "pci" and "scsi". For devices with multiple child busses
they may have different names.
Adding some form of aliases may be convenient. For example the pci machine
could alias "pci0" to "/i440fx/pci", which would give
-device lsi,bus=pci0
-device scsi-disk,bus=pci0/lsi/scsi
We also need to figure out the naming of multiple similar devices on the same
bus. Possibly your "device id" could be used to identify devices on a bus.
e.g. if we wanted two scsi adapters:
-device lsi,bus=pci0,id=foo
-device lsi,bus=pci0,id=bar
-device scsi-disk,bus=pci0/foo/scsi
-device scsi-disk,bus=pci0/bar/scsi

I think what we will see used in practice is:
- either go with the defaults (i.e. don't specify a bus at all
-> device is attached to the first (and often only)
pci/scsi/usb/whatever bus.
- or usage of ids to identify devices and busses.
I think nobody will use stuff like
-device scsi-disk,bus=/main-system-bus/i440FX-pcihost/pci/lsi/scsi
in practice.

Yes.
Provide a bus method to parse the addr property?

Why foo/scsi? Is there a node "scsi" between the lsi device and the
disk? If yes, why?
What's the namespace for ids?
A single, flat namespace would do just fine for me. Then I could do
-device lsi,bus=pci0,id=scsi0
-device lsi,bus=pci0,id=scsi1
-device scsi-disk,bus=scsi0
-device scsi-disk,bus=scsi1

I figure I wouldn't. Still, using tree path names to identify nodes
feels natural. The more convenient id property fits in easily, just
treat is as abbreviation mechanism.
So, I'd be fine with
-device DEVNAME,bus=TREE-PATH,addr=ADDR
where TREE-PATH can start either with / (root node) or an id (start
there instead of at the root), and ADDR is interpreted according to the
bus.

Got it: because qdev distinguishes between device nodes and bus nodes,
there is a scsi bus node between the lsi device node and the scsi-disk
device node.

Would be an option, yes.
I plan to sort bus= first, then look how to solve the addr= puzzle.
>>> -device lsi,bus=pci0,id=foo

scsi bus (and we can't skip it as a scsi adapter might have more than
one bus).
Have hacked up something yesterday, will post RfC patch later today.

2009-07-03 10:22 [Qemu-devel] [PATCH 0/13] qdev patches: properties, -device switch, id=<tag> & more Gerd Hoffmann

This patch is a major overhaul of the device properties. The properties
are saved directly in the device state struct now, the linked list of
property values is gone.
Advantages:
* We don't have to maintain the list with the property values.
* The value in the property list and the value actually used by
the device can't go out of sync any more (used to happen for
the pci.devfn == -1 case) because there is only one place where
the value is stored.
* A record describing the property is required now, you can't set
random properties any more.
There are bus-specific and device-specific properties. The former
should be used for properties common to all bus drivers. Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.
Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties. A few common property
types have PropertyInfos defined in qdev-properties.c. Drivers are free
to implement their own very special property parsers if needed.
Properties can have default values. If unset they are zero-filled.
