      qdev: Decouple qdev_prop_drive from DriveInfo · f8b6cc00
      由 Markus Armbruster 提交于 
      Make the property point to BlockDriverState, cutting out the DriveInfo
middleman.  This prepares the ground for block devices that don't have
a DriveInfo.

Currently all user-defined ones have a DriveInfo, because the only way
to define one is -drive & friends (they go through drive_init()).
DriveInfo is closely tied to -drive, and like -drive, it mixes
information about host and guest part of the block device.  I'm
working towards a new way to define block devices, with clean
host/guest separation, and I need to get DriveInfo out of the way for
that.

Fortunately, the device models are perfectly happy with
BlockDriverState, except for two places: ide_drive_initfn() and
scsi_disk_initfn() need to check the DriveInfo for a serial number set
with legacy -drive serial=...  Use drive_get_by_blockdev() there.

Device model code should now use DriveInfo only when explicitly
dealing with drives defined the old way, i.e. without -device.

      vmstate: Add support for alias ID · 4d2ffa08
      由 Jan Kiszka 提交于 
      Some legacy users (mostly PC devices) of vmstate_register manage
instance IDs on their own, and that unfortunately in a way that is
incompatible with automatically generated ones. This so far prevents
switching those users to vmstates that are registered by qdev.

To establish a migration path, this patch introduces the concept of
alias IDs. They can be passed to an extended vmstate registration
service, and qdev provides a set service to be used during device init.
find_se will consider the alias in addition to the default ID. We can
then start generating the default ID automatically and writing it on
vmsave, thus converting that format without breaking support for upward
migration.

The user is required specify the highest vmstate version for which the
alias is required. Once this version falls behind the minimum required
for a specific vmstate, an assertion triggers to motivate cleaning up
the obsolete alias.

      usb core: use qdev for -usbdevice · 0958b4cc
      由 Gerd Hoffmann 提交于 
      This patchs adds infrastructure to handle -usbdevice via qdev callbacks.
USBDeviceInfo gets a name field (for the -usbdevice driver name) and a
callback for -usbdevice parameter parsing.

The new usbdevice_create() function walks the qdev driver list and looks
for a usb driver with a matching name.  When a parameter parsing
callback is present it is called, otherwise the device is created via
usb_create_simple().

      Fix sys-queue.h conflict for good · 72cf2d4f
      由 Blue Swirl 提交于 
      Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc9235,
f40d7537,
96555a96 and
3990d09a but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.
