      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

      Fix race condition on access to env->interrupt_request · be214e6c
      aurel32 提交于
      env->interrupt_request is accessed as the bit level from both main code
      and signal handler, making a race condition possible even on CISC CPU.
      This causes freeze of QEMU under high load when running the dyntick
      clock.
      
      The patch below move the bit corresponding to CPU_INTERRUPT_EXIT in a
      separate variable, declared as volatile sig_atomic_t, so it should be
      work even on RISC CPU.
      
      We may want to move the cpu_interrupt(env, CPU_INTERRUPT_EXIT) case in
      its own function and get rid of CPU_INTERRUPT_EXIT. That can be done
      later, I wanted to keep the patch short for easier review.
