2012-02-03qom: move properties from qdev to objectAnthony Liguori1-1/+224
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: register all types natively through QEMU Object ModelAnthony Liguori1-0/+2
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>

2012-01-27qom: add the base Object class (v2)Anthony Liguori1-0/+436
This class provides the main building block for QEMU Object Model and is extensively documented in the header file. It is largely inspired by GObject. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> --- v1 -> v2 - remove printf() in type registration - fix typo in comment (Paolo) - make Interface private - move object into a new directory and move header into include/qemu/ - don't make object.h depend on qemu-common.h - remove Type and replace it with TypeImpl * (Paolo) - use hash table to store types (Paolo) - aggressively cache parent type (Paolo) - make a type_register and use it with interfaces (Paolo) - fix interface cast comment (Paolo) - add a few more functions required in later series
