I started out looking at this to reduce divergence of TCG and KVM
machines with 2nd DAWR. The divergence already exists with first
DAWR, so I don't want to tie the KVM 2nd DAWR enablement to this,
but it would be nice to ensure the caps and such for the 2nd DAWR
will also work for TCG.
I don't know that we have great test cases for this, it does work
with some of the Linux selftests ptrace debug tests (although those
tests seem to have a few issues in upstream kernels), some basic
Linux xmon and gdb tests by hand, and I've started working on some
kvm unit tests.
Thanks,
Nick

I am preparing a PR with this series. It is time to take a look at it if you
haven't already !
Thanks,
C.
