This patch makes use of the hw debugging support in kvm (provided by the guest's PER facility) on s390. It enables the following features, available using the gdbserver: - single-stepping - hw breakpoints - hw watchpoints Signed-off-by: David Hildenbrand <dahi@linux.vnet.ibm.com> Signed-off-by: Jens Freimann <jfrei@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
