acpi.pci,pc,memory core fixes Most notably this includes changes to exec to support full 64 bit addresses. This also flushes out patches that got queued during 1.7 freeze. There are new tests, and a bunch of bug fixes all over the place. There are also some changes mostly useful for downstreams. I'm also listing myself as pc co-maintainer. I'm doing this reluctantly, but this seems to be necessary to make sure patches are not lost or delayed too much, and posting the MAINTAINERS patch did not seem to make anyone else volunteer.

2013-12-11hpet: enable to entitle more irq pins for hpetLiu Ping Fan
Owning to some different hardware design, piix and q35 need different compat. So making them diverge. On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23 can be assigned to hpet as guest chooses. So we introduce intcap property to do that. Consider the compat and piix/q35, we finally have the following value for intcap: For piix, hpet's intcap is hard coded as IRQ2. For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise IRQ2, IRQ8, and IRQ16~23 are allowed. Signed-off-by: Liu Ping Fan <pingfank@linux.vnet.ibm.com> Reviewed-by: Michael S.

2013-12-10smbios: Set system manufacturer, product & version by defaultMarkus Armbruster
Currently, we get SeaBIOS defaults: manufacturer Bochs, product Bochs, no version. Best SeaBIOS can do, but we can provide better defaults: manufacturer QEMU, product & version taken from QEMUMachine desc and name. Take care to do this only for new machine types, of course. Note: Michael Tsirkin doesn't trust us to keep values of QEMUMachine member product stable in the future. Use copies instead, and in a way that makes it obvious that they're guest ABI. Note that we can be trusted to keep values of member name, because that has always been ABI. Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S.

2013-12-10qtest: split configuration of qtest accelerator and chardevPaolo Bonzini
qtest uses the icount infrastructure to implement a test-driven vm_clock. This however is not necessary when using -qtest as a "probe" together with a normal TCG-, KVM- or Xen-based virtual machine. Hence, split out the call to configure_icount into a new function that is called only for "-machine accel=qtest"; and disable those commands when running with an accelerator other than qtest. This also fixes an assertion failure with "qemu-system-x86_64 -machine accel=qtest" but no -qtest option. This is a valid case, albeit somewhat weird; nothing will happen in the VM but you'll still be able to interact with the monitor or the GUI. Now that qtest_init is not limited to an int(void) function, change global variables that are not used outside qtest_init to arguments. And finally, cleanup useless parts of include/sysemu/qtest.h. The file is not used at all for user-only emulation, and qtest is not available on Win32 due to its usage of sigwait. Reported-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Michael S.

2013-12-09virtio-bus: cleanup plug/unplug interfacePaolo Bonzini
Right now we have these pairs: - virtio_bus_plug_device/virtio_bus_destroy_device. The first takes a VirtIODevice, the second takes a VirtioBusState - device_plugged/device_unplug callbacks in the VirtioBusClass (here it's just the naming that is inconsistent) - virtio_bus_destroy_device is not called by anyone (and since it calls qdev_free, it would be called by the proxies---but then the callback is useless since the proxies can do whatever they want before calling virtio_bus_destroy_device) And there is a k->init but no k->exit, hence virtio_device_exit is overwritten by subclasses (except virtio-9p). This cleans it up by: - renaming the device_unplug callback to device_unplugged - renaming virtio_bus_plug_device to virtio_bus_device_plugged, matching the callback name - renaming virtio_bus_destroy_device to virtio_bus_device_unplugged, removing the qdev_free, making it take a VirtIODevice and calling it from virtio_device_exit - adding a k->exit callback virtio_device_exit is still overwritten, the next patches will fix that.

Previously a BlockDriverState has only one dirty bitmap, so only one caller (e.g. a block job) can keep track of writing. This changes the dirty bitmap to a list and creates a BdrvDirtyBitmap for each caller, the lifecycle is managed with these new functions: bdrv_create_dirty_bitmap bdrv_release_dirty_bitmap Where BdrvDirtyBitmap is a linked list wrapper structure of HBitmap. In place of bdrv_set_dirty_tracking, a BdrvDirtyBitmap pointer argument is added to these functions, since each caller has its own dirty bitmap: bdrv_get_dirty bdrv_dirty_iter_init bdrv_get_dirty_count bdrv_set_dirty and bdrv_reset_dirty prototypes are unchanged but will internally walk the list of all dirty bitmaps and set them one by one.

2013-11-28block: introduce bdrv_make_zeroPeter Lieven
this patch adds a call to completely zero out a block device. the operation is sped up by checking the block status and only writing zeroes to the device if they currently do not return zeroes. optionally the zero writing can be sped up by setting the flag BDRV_REQ_MAY_UNMAP to emulate the zero write by unmapping if the driver supports it.
