2015-01-20exec.c: Drop TARGET_HAS_ICE define and checksPeter Maydell1-2/+0
The TARGET_HAS_ICE #define is intended to indicate whether a target-* guest CPU implementation supports the breakpoint handling. However, all our guest CPUs have that support (the only two which do not define TARGET_HAS_ICE are unicore32 and openrisc, and in both those cases the bp support is present and the lack of the #define is just a bug). So remove the #define entirely: all new guest CPU support should include breakpoint handling as part of the basic implementation.

After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2013-07-29cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"Andreas Färber1-2/+3
Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code. This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed". The reason for the failure is that CPUClass::kvm_fd is not yet initialized in the following call graph: ->x86_cpu_realizefn ->x86_cpu_apic_realize ->qdev_init ->device_set_realized ->device_reset (hotplugged == 1) ->apic_reset_common ->vapic_base_update ->kvm_apic_vapic_base_update This causes attempted KVM vCPU ioctls to fail. By contrast, in the non-hotplug case the APIC is reset much later, when the vCPU is already initialized. As a quick and safe solution, move the qemu_init_vcpu() call back into the targets' realize functions.

Since commit 878096eeb278a8ac1ccd6667af73e026f29b4cf5 (cpu: Turn cpu_dump_{state,statistics}() into CPUState hooks) CPUArchState is no longer needed. Add documentation and make the functions available through qemu/log.h outside NEED_CPU_H to allow use in qom/cpu.c. Moving them to qom/cpu.h was not yet possible due to convoluted include paths, so that some devices grow an implicit and unneeded dependency on qom/cpu.h for now.

2013-07-09cpu: Drop unnecessary dynamic casts in *_env_get_cpu()Andreas Färber1-1/+1
A transition from CPUFooState to FooCPU can be considered safe, just like FooCPU::env access in the opposite direction. The only benefit of the FOO_CPU() casts would be protection against bogus CPUFooState pointers, but then surrounding code would likely break, too. This should slightly improve interrupt etc. performance when going from CPUFooState to FooCPU. For any additional CPU() casts see 3556c233d931ad5ffa46a35cb25cfc057732ebb8 (qom: allow turning cast debugging off).
