      hw/sysbus: Add sysbus_mmio_get_region() · 46c305ef
      由 Peter Maydell 提交于 
      Add a sysbus_mmio_get_region() which allows users of sysbus
devices to turn a (SysBusDevice*, mmioidx) tuple into a
MemoryRegion*. This enables some useful simplifications of
devices which pass through another device's mmio region
(either directly or by implementing some kind of memory
controller device).

      New qdev_init_nofail() · e23a1b33
      由 Markus Armbruster 提交于 
      Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.

Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because
we know that failure can't happen.

Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling.  I'm leaving
that for another day, because it involves making sure that error
values are properly checked by all callers.

      qdev: add return value to init() callbacks. · 81a322d4
      由 Gerd Hoffmann 提交于 
      Sorry folks, but it has to be.  One more of these invasive qdev patches.

We have a serious design bug in the qdev interface:  device init
callbacks can't signal failure because the init() callback has no
return value.  This patch fixes it.

We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault.  This patch fixes it.

With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.

      qdev: replace bus_type enum with bus_info struct. · 10c4c98a
      由 Gerd Hoffmann 提交于 
      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.

      Add common BusState · 02e2da45
      由 Paul Brook 提交于 
      Implement and use a common device bus state.  The main side-effect is
that creating a bus and attaching it to a parent device are no longer
separate operations.  For legacy code we allow a NULL parent, but that
should go away eventually.

Also tweak creation code to veriry theat a device in on the right bus.
