2014-10-20hw: Convert from BlockDriverState to BlockBackend, mostlyMarkus Armbruster
Device models should access their block backends only through the block-backend.h API. Convert them, and drop direct includes of inappropriate headers. Just four uses of BlockDriverState are left: * The Xen paravirtual block device backend (xen_disk.c) opens images itself when set up via xenbus, bypassing blockdev.c. I figure it should go through qmp_blockdev_add() instead. * Device model "usb-storage" prompts for keys. No other device model does, and this one probably shouldn't do it, either. * ide_issue_trim_cb() uses bdrv_aio_discard() instead of blk_aio_discard() because it fishes its backend out of a BlockAIOCB, which has only the BlockDriverState. * PC87312State has an unused BlockDriverState[] member. The next two commits take care of the latter two. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2014-10-20block: Eliminate DriveInfo member bdrv, use blk_by_legacy_dinfo()Markus Armbruster
The patch is big, but all it really does is replacing dinfo->bdrv by blk_bs(blk_by_legacy_dinfo(dinfo)) The replacement is repetitive, but the conversion of device models to BlockBackend is imminent, and will shorten it to just blk_legacy_dinfo(dinfo). Line wrapping muddies the waters a bit. I also omit tests whether dinfo->bdrv is null, because it never is.

2014-10-15qdev: HotplugHandler: Rename unplug callback to unplug_requestIgor Mammedov
'HotplugHandler.unplug' callback is currently used as async call to issue unplug request for device that implements it. Renaming 'unplug' callback to 'unplug_request' should help to avoid confusion about what callback does and would allow to introduce 'unplug' callback that would perform actual device removal when guest is ready for it.

2014-05-05PortioList: Store PortioList in device stateKirill Batuzov
PortioList is an abstraction used for construction of MemoryRegionPortioList from MemoryRegionPortio. It can be used later to unmap created memory regions. It also requires proper cleanup because some of the memory inside is allocated dynamically. By moving PortioList ot device state we make it possible to cleanup later and avoid leaking memory. This change spans several target platforms.

2013-12-23sysbus: Set cannot_instantiate_with_device_add_yetMarkus Armbruster
device_add plugs devices into suitable bus. For "real" buses, that actually connects the device. For sysbus, the connections need to be made separately, and device_add can't do that. The device would be left unconnected, and could not possibly work. Quite a few, but not all sysbus devices already set cannot_instantiate_with_device_add_yet in their class init function. Set it in their abstract base's class init function sysbus_device_class_init(), and remove the now redundant assignments from device class init functions.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.
