    Guest debugging support for KVM (Jan Kiszka) · e22a25c9
    aliguori 提交于
    This is a backport of the guest debugging support for the KVM
    accelerator that is now part of the KVM tree. It implements the reworked
    KVM kernel API for guest debugging (KVM_CAP_SET_GUEST_DEBUG) which is
    not yet part of any mainline kernel but will probably be 2.6.30 stuff.
    So far supported is x86, but PPC is expected to catch up soon.
    
    Core features are:
     - unlimited soft-breakpoints via code patching
     - hardware-assisted x86 breakpoints and watchpoints
    
    Changes in this version:
     - use generic hook cpu_synchronize_state to transfer registers between
       user space and kvm
     - push kvm_sw_breakpoints into KVMState
