2013-03-01hw: include hw header files with full pathsPaolo Bonzini
Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

2013-01-10Make all static TypeInfos constAndreas Färber
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr.

2012-10-03xen: Fix, no unplug of pt device by platform device.Anthony PERARD
The Xen platform device will unplug any NICs if requested by the guest (PVonHVM) including a NIC that would have been passthrough. This patch makes sure that a passthrough device will not be unplug.

2012-08-23qom: object_delete should unparent the object firstPaolo Bonzini
object_deinit is only called when the reference count goes to zero, and yet tries to do an object_unparent. Now, object_unparent either does nothing or it will decrease the reference count. Because we know the reference count is zero, the object_unparent call in object_deinit is useless. Instead, we need to disconnect the object from its parent just before we remove the last reference apart from the parent's. This happens in object_delete. Once we do this, all calls to object_unparent peppered through QEMU can go away. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-05-21xen: Fix PV-on-HVMAnthony PERARD
In the context of PV-on-HVM under Xen, the emulated nics are supposed to be unplug before the guest drivers are initialized, when the guest write to a specific IO port. Without this patch, the guest end up with two nics with the same MAC, the emulated nic and the PV nic.

2012-04-09qdev: qdev_unplug(): use error_set()Luiz Capitulino
It currently uses qerror_report(), but next commit will convert the drive_del command to the QAPI and this requires using error_set(). One particularity of qerror_report() is that it knows when it's running on monitor context or command-line context and prints the error message accordingly. error_set() doesn't do this, so we have to be careful not to drop error messages. qdev_unplug() has three kinds of usages: 1. It's called when hot adding a device fails, to undo anything that has been done before hitting the error 2. It's called by function monitor functions like device_del(), to unplug a device 3. It's used by xen_platform.c in a way that doesn't _seem_ to be in monitor context Only item 2 can print an error message to the user, this commit maintains that.

2012-02-15qom: Unify type registrationAndreas Färber
Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-12-05block: convert qemu_aio_flush() calls to bdrv_drain_all()Stefan Hajnoczi
Many places in QEMU call qemu_aio_flush() to complete all pending asynchronous I/O. Most of these places actually want to drain all block requests but there is no block layer API to do so. This patch introduces the bdrv_drain_all() API to wait for requests across all BlockDriverStates to complete. As a bonus we perform checks after qemu_aio_wait() to ensure that requests really have finished.

2011-07-26xen: implement unplug protocol in xen_platformStefano Stabellini
The unplug protocol is necessary to support PV drivers in the guest: the drivers expect to be able to "unplug" emulated disks and nics before initializing the Xen PV interfaces. It is responsibility of the guest to make sure that the unplug is done before the emulated devices or the PV interface start to be used. We use pci_for_each_device to walk the PCI bus, identify the devices and disks that we want to disable and dynamically unplug them. Changes in v2: - use PCI_CLASS constants; - replace pci_unplug_device with qdev_unplug; - do not import hw/ide/internal.h in xen_platform.c; Changes in v3: - introduce piix3-ide-xen, that support hot-unplug; - move the unplug code to hw/ide/piix.c; - just call qdev_unplug from xen_platform.c to unplug the IDE disks; Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Acked-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Alexander Graf <agraf@suse.de>
