      GPIO I2C rework · 3cd035d8
      由 Paul Brook 提交于 
      Reqrite bitbanging I2C implementation.  New code improves stop/start
condition handling, and gives more accurate input line level.

Introduce intermediate abstraction layer for I2C bitbanging that
is not connected via a GPIO port.

      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.

      kill drives_table · 751c6a17
      由 Gerd Hoffmann 提交于 
      First step cleaning up the drives handling.  This one does nothing but
removing drives_table[], still it became seriously big.

drive_get_index() is gone and is replaced by drives_get() which hands
out DriveInfo pointers instead of a table index.  This needs adaption in
*tons* of places all over.

The drives are now maintained as linked list.

      qdev: rework device properties. · ee6847d1
      由 Gerd Hoffmann 提交于 
      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.

      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.

      Introduce reset notifier order · 8217606e
      由 Jan Kiszka 提交于 
      Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.

Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

      Remove vga_ram_size · fbe1b595
      由 Paul Brook 提交于 
      The vga_ram_size argument to machine init functions always has the same
value, and is ignored by many machines (including SPARC32 which has an
obsolete ifdef for VGA_RAM_SIZE).

Remove it and push VGA_RAM_SIZE into vga_int.h.

      Make AUD_init failure fatal · 0d9acba8
      由 Paul Brook 提交于 
      Failure to initialize the audio subsystem is not handled consistently.
Where it is handled it has guest visible effects, which is wrong.
We already have a "nosound" audio driver as a last resort, so trying to
proceed without an audio backend seems pointless.

Also protect against multiple calls to AUD_init so that this can be
pushed down into individual devices.
