2012-02-15device_add: don't add a /peripheral link until init is completeAnthony Liguori
Otherwise we end up with a dangling reference which causes qdev_free() to fail. Reported-by: Michael Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
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.

2012-02-14qdev: print error message before abortingPaolo Bonzini
qdev_prop_set_* functions are always called by machine init functions that should know what they're doing, so they abort on error. Still, an assert(!errp) does not aid debugging. Print an error before aborting. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-02-09AHCI: Masking of IRQs actually masks themAlexander Graf
When masking IRQ lines, we should actually mask them out and not declare them active anymore. Once we mask them in again, they are allowed to trigger again. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-02-09AHCI: Fix port reset raceAlexander Graf
bdrv_aio_cancel() can trigger bdrv_aio_flush() which makes all aio that is currently in flight finish. So what we do is: port reset detect ncq in flight cancel ncq delete ncq sg list at which point we have double freed the sg list. Instead, with this patch we do: port reset detect ncq in flight cancel ncq check if we are really still in flight delete ncq sg list which makes things work and gets rid of the race.

2012-02-09ARM devboards: Set arm_sysctl properties before init, not afterPeter Maydell
The ARM devboard models (vexpress-a9, realview, versatilepb, etc) were accidentally trying to set one of the arm_sysctl properties after device init. This has now become a fatal error; set the property before device init where it should be done instead. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2012-02-07qdev: initialize properties via QOMPaolo Bonzini
Similarly, use the object properties also to set the default values of the qdev properties. This requires reordering registration and initialization. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-02-07qdev: remove parse/print methods for pointer propertiesPaolo Bonzini
Pointer properties (except for PROP_PTR of course) should not need a legacy counterpart. In the future, relative paths will ensure that QEMU will support the same syntax as now for drives etc.. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-02-07qdev: make the non-legacy pci address property accept an integerPaolo Bonzini
PCI addresses are set with qdev_prop_uint32. Thus we make the QOM property accept a device and function encoded in an 8-bit integer, instead of the magic dd.f hex string. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-02-07qdev: remove parse method for string propertiesPaolo Bonzini

2012-02-07qdev: allow reusing get/set for legacy propertyPaolo Bonzini
In some cases, a legacy property does need a special print method but not a special parse method. In this case, we can reuse the get/set from the static (non-legacy) property. If neither parse nor print is needed, though, do not register the legacy property at all. The previous patch ensures that the right fallback will be used. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-02-07qdev: remove direct calls to print/parsePaolo Bonzini
There's no need to call into ->parse and ->print manually. The QOM legacy properties do that for us. Furthermore, in some cases legacy and static properties have exactly the same behavior, and we could drop the legacy properties right away. Add an appropriate fallback to prepare for this.

2012-02-03qom: move properties from qdev to objectAnthony Liguori
This is mostly code movement although not entirely. This makes properties part of the Object base class which means that we can now start using Object in a meaningful way outside of qdev. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03qdev: nuke qdev_init_chardev()Anthony Liguori

2012-02-03qdev: refactor away qdev_create_from_infoAnthony Liguori

2012-02-03qdev: split out common init to instance_initAnthony Liguori

2012-02-03qdev: remove baked in notion of aliases (v2)Anthony Liguori
Limit them to the device_add functionality. Device aliases were a hack based on the fact that virtio was modeled the wrong way. The mechanism for aliasing is very limited in that only one alias can exist for any device. We have to support it for the purposes of compatibility but we only need to support it in device_add so restrict it to that piece of code.

2012-02-03qdev: kill off DeviceInfoAnthony Liguori
It is no longer used in the tree since everything is done natively through QEMU Object Model. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
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>
