Hi,
This is a respin of my qdev patches. They are rebased to the latest
master.
The first two patches are almost unmodified since the last time I posted
them, I think they are ready to be merged. The pci registration patch
addresses the pci config space access issue, which must be fixed because
otherwise some PCI drivers can't be converted to qdev.
The other patches switch over various drivers and busses to qdev. They
depend on the first two patches. The conversion work is far from being
completed. Currently my main focus is on getting all devices into the
qdev tree. Most drivers are not (yet) in a state where creating them
from a fdt can actually work though. IMHO the patches are useful
nevertheless. YMMV, feel free to cherry-pick some of the patches only.
Open issues:
usb: The way qemu manages usb ports, hubs and busses needs fixing.
Right now qemu manages ports only.
scsi: linking host-devs + guest-devs isn't solved yet.
Needed for bdrv + scsi-disk to complete scsi conversion.
ide: not even started yet.
The patches can also be pulled from
git://git.et.redhat.com/qemu-kraxel.git (branch qdev.v4).
Note: the git tree also has the alsa warning fix so the tree actually
builds ...
cheers,
Gerd

Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch
of parameters. Also adds config_read and config_write callbacks to
PCIDeviceInfo, so drivers needing these can be converted to the qdev
device API too.

BusInfo is filled with name and size (pretty much like I did for
DeviceInfo as well). There is also a function pointer to print
bus-specific device information to the monitor. sysbus is hooked
up there, I've also added a print function for PCI.
Device creation is slightly modified as well: The device type search
loop now also checks the bus type while scanning the list instead of
complaining thereafter in case of a mismatch. This effectively gives
each bus a private namespace for device names.

The only purpose DeviceType serves is creating a linked list of
DeviceInfo structs. This removes DeviceType and add a next field to
DeviceInfo instead, so the DeviceInfo structs can be changed that way.
Elimitates a pointless extra level of indirection.

Hi,
> The patches can also be pulled from

Updated patch queue pushed to qdev.v5. Not posting to avoid spamming
the list too much. Online viewable via gitweb here:
http://git.et.redhat.com/?p=qemu-kraxel.git;a=shortlog;h=refs/heads/qdev.v5
Changes:
* bunch of minor fixes and improvements.
* more verbose commit messages.
* more usb work, teach qemu about busses, it can deal with more
than one usb bus now.
enjoy,
Gerd

Todays update pushed to qdev.v6.
http://git.et.redhat.com/?p=qemu-kraxel.git;a=shortlog;h=refs/heads/qdev.v6
Changes:
* Reordered patches:
- First the patches with the core changes.
- Then conversion of some PCI drivers.
- Next USB.
- Next SCSI.
- Finally some test patches I've used to play with multiple
USB busses.
The core patches are needed for all others. The usb-related
patches build on each other and must be applied in order.
SCSI goes after USB because of usb-storage. Otherwise the
patches should be independent on each other.
* Converted VGA drivers and ac97/es1370 to qdev.
* Minor tweaks.
cheers,
Gerd

I'm not so convinced. I don't see much value in "dummy" conversion that still
requires use of the old APIs to create devices.

A few comments on specific patches:
* qdev: update pci device registration
I dislike passing an {array,length} pair. Especially when it requires every
user to manually get the right length.
* qdev/core: bus list
I don't seen any good reason for this. In fact I think it is a major step
backwards. A bus is uniquely identified by its name and parent device.
* qdev/pci: misc fixes.
All uses of the second argument to savevm should go away, not introduce new
ones. I'm unconvinced by the dev->name change. If we're using the same value
then why does it exist at all?
* qdev/pci: hook up i440fx
i440fx_init should not exist. c.f. versatile_pci.c
* qdev: update pci device registration
This is exactly the sort of fake conversion that I don't like, because you
still require use of the old hardcoded initialization functions.
Convenience wrappers like smc91c111_init are fine (and will naturally
disappear when we have a machine config), but you shouldn't be poking directly
at device state.
In practice there's no way for the user to have more than one set of IDE
busses, so I don't see much point pretending we allow this. i.e. remove the
hd_table argument altogether and use drive_get_index directly.
* qdev: convert all vga
Likewise, pci_vga_init needs to go away.
* qdev/scsi: add scsi bus support to qdev, convert drivers
This still feels wrong, probably because you're using the same thing for both
a parallel scsi bus, and for devices (usb-msd) that incorporate scsi
functionality directly. The current qemu scsi API is actually a set of point
to point links with individual devices. All the bus emulation is local to the
host controller.
* qdev/usb*
I have not looked at these patches.

qemu has a ARRAY_SIZE macro which can be used like this:
(from uhci patch):
pci_qdev_register(uhci_info, ARRAY_SIZE(uhci_info));
to get the right length, so I don't see this as a problem.
I can create pci_qdev_register_{single,array} macros to hide the length
parameter. I can also just drop the length argument and just use
multiple calls in the (few) places where multiple drivers are registered
at once. What do you prefer?

For a static device tree you don't need that indeed. I've added the
patch recently while hacking usb, the reason is hotplugging devices.
When adding devices to busses using monitor commands you'll need some
way to specify the bus and to find it. This gets the job done without
having to walk the whole device tree.

This just maintains current behavior (PCI busses are numbered starting
zero).

It is redundant indeed. I've considered dropping it right away, then
decided to better wait with that step until all PCI drivers are
converted to qdev.

Indeed. That is the long-term plan, I'm just not there yet.

Guess this was supposed to say "qdev: convert piix-ide." ?

I'd prefer to call them "incomplete" instead of "fake". I know that
more work needs to be done to get the drivers into shape for a dt-driven
machine creation.
> Convenience wrappers like smc91c111_init are fine
Yes, that is the plan for all drivers. So the old, hardcoded way of
doing things keeps working while we are busy making the dt-driven
machine creation work.
I'm just not there yet in all cases. Basically every old *_init() call
which has more than a single $bus_create_simple(...) call needs more work.
cheers,
Gerd

There's a third alternative, zero terminating the array.
If most calls register one qdev, I'd prefer pci_qdev_register() and
pci_qdev_register_many().

Where register() takes a single instance and register_many() a
zero-terminated array I guess? Sounds good.

i.e. something like the attached patch (incremental to the whole patch
series).

I tend to kill the drives_table[] completely. It mixes host and guest
state, we need to separate them.
For the host side I think about a linked list built from stripped down
DriveInfo which contains the hostside info only (BlockDriverState +
friends) and a name to reference it.
The guest side will link to the host side state using the name, probably
passed as attribute.
cheers,
Gerd

To followup with some more backgroud on that on that: These are cases
where additional arguments are passed to the *_init() function.
Partly the reason is irq windup (i.e. passing around qemu_irqs), which
must be adapted. Didn't investigate that one yet. Probably non-trivial
to the way interrupts work (pic, lapic, ioapic, ...) in PCs.
Partly the arguments carry extra configutation info. In that case the
info should probably come as attributes from the the device tree.
Didn't look (yet) into using attributes, one of the reasons being that
the API for them is still quite unclear.
cheers,
Gerd

What's wrong with merging an intermediate step, as long as it doesn't
break anything, clearly moves in the right direction, and the developer
can be trusted to go the rest of the way?
Forcing him to keep his substantial patches out of tree until they're
perfectly complete just creates merging & rebasing hassle for him, which
can only slow him down. Moreover, it keeps his work less visible, and
thus risks duplicated effort.
