2014-02-28dump: const-qualify the buf of WriteCoreDumpFunctionqiaonuohan1-1/+2
WriteCoreDumpFunction is a function pointer that points to the function used to write content in "buf" into core file, so "buf" should be const-qualify.

2014-01-28add optional 2nd stage initialization to -object/object-add commandsIgor Mammedov1-0/+62
Introduces USER_CREATABLE interface that must be implemented by objects which are designed to created with -object CLI option or object-add QMP command. Interface provides an ability to do an optional second stage initialization of the object created with -object/object-add commands. By providing complete() callback, which is called after the object properties were set. It allows to: * prevents misusing of -object/object-add by filtering out objects that are not designed for it. * generalize second stage backend initialization instead of adding custom APIs to perform it * early error detection of backend initialization at -object/ object-add time rather than through a proxy DEVICE object that tries to use backend.

2013-12-24qom: Do not register interface "types" in the type table and fix namesPaolo Bonzini1-0/+1
There should be no need to look up nor enumerate the interface "types", whose "classes" are really just vtables. Just create the types and add them to the interface list of the parent type. Interfaces not registering their type anymore means that accessing superclass::interface by type name will fail when initializing subclass::interface. Thus, we need to pre-initialize the subclass's parent_type field before calling type_initialize. Apart from this, the interface "types" should never be used and thus it is harmless to leave them out of the hashtable. Further, the interface types had a bug with interfaces that are inherited from a superclass: The implementation type name was wrong (for example it was subclass::superclass::interface rather than just subclass::interface). This patch fixes this as well.

2013-12-24qom: Split out object and class cachesPeter Crosthwaite1-1/+2
The object-cast and class-cast caches cannot be shared because class caching is conditional on the target type not being an interface and object caching is unconditional. Leads to a bug when a class cast to an interface follows an object cast to the same interface type: FooObject = FOO(obj); FooClass = FOO_GET_CLASS(obj); Where TYPE_FOO is an interface. The first (object) cast will be successful and cache the casting result (i.e. TYPE_FOO will be cached). The second (class) cast will then check the shared cast cache and register a hit. The issue is, when a class cast hits in the cache it just returns a pointer cast of the input class (i.e. the concrete class). When casting to an interface, the cast itself must return the interface class, not the concrete class. The implementation of class cast caching already ensures that the returned cast result is only a pointer cast before caching. The object cast logic however does not have this check. Resolve by just splitting the object and class caches.

Commit a0e372f0c49ac01faeaeb73a6e8f50e8ac615f34 reorganized the register counting for GDB. While it seems correct not to let the total number of registers skyrocket in an SMP scenario through a static variable, the distinction between total register count and 'g' packet register count (last_reg vs. num_g_regs) got lost among the way. Fix this by introducing CPUState::gdb_num_g_regs and using that in gdb_handle_packet().

This patch adds a small typename cache to ObjectClass. This allows caching positive casts within each ObjectClass. Benchmarking a PPC workload provided by Aurelien, this patch eliminates every single g_hash_table_lookup() happening during the benchmark (which was about 2 million per-second). With this patch applied, I get exactly the same performance (within the margin of error) as with --disable-qom-cast-debug.
