Will kvm_openfiles fail for non-native > cores? or will kvm_read fail for non-native cores? kvm_openfiles() will fail. kvm_open2() will fail for a non-native core if a symbol resolving routine is not supplied. One API question I had is if it would be useful to allow a void * cookie to be passed to the symbol resolving routine (the same cookie would be passed to kvm_open2() and stored internally to be passed on each resolution request). I think in practice we don't need that level of complexity though (my kgdb changes did not). I will need to rebase this to port the arm64 minidump support over, but I also need people to test this. -- John Baldwin
