2014-03-13cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber43-73/+94
Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>

2014-03-13cpu: Turn cpu_handle_mmu_fault() into a CPUClass hookAndreas Färber61-151/+238
Note that while such functions may exist both for *-user and softmmu, only *-user uses the CPUState hook, while softmmu reuses the prototype for calling it directly. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13target-m68k: Remove custom qemu_assert() functionPeter Maydell1-19/+9
Remove the custom qemu_assert() function defined by target-m68k/translate.c in favour of either using glib g_assert_not_reached() (for the genuinely can't-happen cases) or cpu_abort() (for the "this isn't implemented", in line with other unimplemented cases in the target). This has the benefit of silencing some clang warnings about variables used while uninitialized (which are emitted because clang can't figure out that qemu_assert(0, something) never returns.

2014-03-13cpu: Factor out cpu_generic_init()Andreas Färber10-103/+62
All targets using it gain the ability to set -cpu name,key=value,... options via the default TYPE_CPU CPUClass::parse_features() implementation. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13cpu: Implement CPUClass::parse_features() for the rest of CPUsAndreas Färber1-1/+30
CPUs who do not provide their own implementation of feature parsing will treat each option as a QOM property and set it to the supplied value. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13target-sparc: Defer SPARCCPU feature inference to QOM realizeAndreas Färber1-5/+8

2014-03-13target-sparc: Implement CPUClass::parse_features() for SPARCCPUAndreas Färber1-33/+49
Factor cpu_model parsing out of cpu_sparc_find_by_name() by passing cpu_sparc_find_by_name() the name portion only and calling CPUClass::parse_features() from cpu_sparc_register() afterwards.

2014-03-13cpu: Introduce CPUClass::parse_features() hookAndreas Färber2-15/+23
Adapt the X86CPU implementation to suit the generic hook. This involves a cleanup of error handling to cope with NULL errp. Reviewed-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13target-i386: X86CPU model subclassesEduardo Habkost2-73/+125
Register separate QOM types for each x86 CPU model. This will allow management code to more easily probe what each CPU model provides, by simply creating objects using the appropriate class name, without having to restart QEMU. This also allows us to eliminate the qdev_prop_set_globals_for_type() hack to set CPU-model-specific global properties. Instead of creating separate class_init functions for each class, I just used class_data to store a pointer to the X86CPUDefinition struct for each CPU model. This should make the patch shorter and easier to review. Later we can gradually convert each X86CPUDefinition field to lists of per-class property defaults. The "host" CPU model is special, as the feature flags depend on KVM being initialized. So it has its own class_init and instance_init function, and feature flags are set on instance_init instead of class_init.

2014-03-13target-i386: Enable x2apic by default on KVMEduardo Habkost3-0/+3
When on KVM mode, enable x2apic by default on all CPU models. Normally we try to keep the CPU model definitions as close as the real CPUs as possible, but x2apic can be emulated by KVM without host CPU support for x2apic, and it improves performance by reducing APIC access overhead. x2apic emulation is available on KVM since 2009 (Linux 2.6.32-rc1), there's no reason for not enabling x2apic by default when running KVM.

There isn't any kind of "registration" involved in cpu_x86_register() anymore: it is simply looking up a CPU model name and loading the model definition data into the X86CPU object.
