2012-06-18qdev: Convert busses to QEMU Object ModelAnthony Liguori
This is far less interesting than it sounds. We simply add an Object to each BusState and then register the types appropriately. Most of the interesting refactoring will follow in the next patches. Since we're changing fundamental type names (BusInfo -> BusClass), it all needs to convert at once. Fortunately, not a lot of code is affected.

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>
2012-01-27sysbus: apic: ioapic: convert to QEMU Object ModelAnthony Liguori
This converts three devices because apic and ioapic are subclasses of sysbus. Converting subclasses independently of their base class is prohibitively hard. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-08-28hw/sysbus: Add sysbus_mmio_get_region()Peter Maydell
Add a sysbus_mmio_get_region() which allows users of sysbus devices to turn a (SysBusDevice*, mmioidx) tuple into a MemoryRegion*. This enables some useful simplifications of devices which pass through another device's mmio region (either directly or by implementing some kind of memory controller device).

2011-08-22sysbus: remove sysbus_init_mmio_cb()Avi Kivity
This problem with this function is that it is not reversible - it is impossible to know where things are registered and unregister them exactly. As there are no more users, we can remove it. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann
Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.
