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 Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6825 c046a42c-6fe2-441c-8c8c-71466251a162
