Calculate the system clock period on reset; otherwise it remains set to the default value of zero and attempting to use it provokes a hang. This is one of the issues noted in LP:696094.

Remove some dependency rules which aren't necessary (the automatically generated .d files cover all these). These were leftovers from dyngen days, when the object files also had a dependency on some generated files.

This patch fixes a bug where child processes of launch_script() can misbehave due to SIGCHLD being blocked. In the case of `sudo`, this causes a permanent hang. Previously a SIGCHLD handler was added to reap fork_exec()'d zombie processes by calling waitpid(-1, ...). This required other fork()/waitpid() callers to temporarilly block SIGCHILD to avoid having the final wait status being intercepted by the SIGCHLD handler: 7c3370d4 Since then, the qemu_add_child_watch() interface was added to allow registration of such processes and reap only from that specific set of PIDs: 4d54ec78 As a result, we can now avoid blocking SIGCHLD in launch_script(), so drop that behavior.

Commit f462141f introduced clean up code when usb_qdev_init() fails. Unfortunately it calls .handle_destroy() when .init() was never invoked or failed. This can lead to crashes when .handle_destroy() tries to clean up things that were never initialized. This patch is careful to undo only those steps that completed along the usb_qdev_init() code path. It's not as pretty as the unified error handling in f462141f but it's necessary.

Commit 95c318f5 (Fix segfault in mmio subpage handling code.) prevented a segfault by making all subpage registrations over an existing memory page perform an unassigned access. Symptoms were writes not taking effect and reads returning zero. Very small page sizes are not currently supported either, so subpage memory areas cannot fully be avoided. Therefore change the previous fix to use a new IO_MEM_SUBPAGE_RAM instead of IO_MEM_UNASSIGNED. Suggested by Avi.

In help() we do what boils down to: printf("%s", "qemu"); This seems to be an artifact of be995c27 ("removed unused code"), which removed some ifdef'ery that used to print a different name depending on CONFIG_SOFTMMU.

This really shows the power of dynamic object properties compared to qdev static properties. This property represents a complex structure who's format is preserved over the wire. This is enabled by visitors. It also shows an entirely synthetic property that is not tied to device state. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This allows clients to read and write device model properties through QMP. QAPI doesn't support Visitor types yet and these commands are special in that they don't work with fixed types.

Links represent an ephemeral relationship between devices. They are meant to replace the qdev concept of busses by allowing more informal relationships between devices. Links are fairly limited in their usefulness without implementing QOM-style subclassing and interfaces. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

There are two types of supported paths--absolute paths and partial paths. Absolute paths are derived from the root device and can follow child<> or link<> properties. Since they can follow link<> properties, they can be arbitrarily long. Absolute paths look like absolute filenames and are prefixed with a leading slash. Partial paths are look like relative filenames. They do not begin with a prefix. The matching rules for partial paths are subtle but designed to make specifying devices easy. At each level of the composition tree, the partial path is matched as an absolute path. The first match is not returned. At least two matches are searched for. A successful result is only returned if only one match is founded. If more than one match is found, a flag is returned to indicate that the match was ambiguous. At the end of the day, partial path support means that if you create a device called 'ide0', you can just say 'ide0' as the path name and it will Just Work. If we internally create a device called 'i440fx', you can just say 'i440fx' and it will Just Work and long as you don't do anything silly. A management tool should probably always use absolute paths since then they don't have to deal with the possibility of ambiguity. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

The canonical path is the path in the composition tree from the root to the device. This is effectively the name of the device. This is an incredibly unefficient implementation that will be optimized in a future patch. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

qdev properties are settable only during construction and static to classes. This isn't flexible enough for QOM. This patch introduces a property interface for qdev that provides dynamic properties that are tied to objects, instead of classes. These properties are Visitor based instead of string based too.
