[RFT] Rebased gdb/debug register patches

[RFT] Rebased gdb/debug register patches

[Jan Kiszka]

Hi,

this is not yet the official submission, but a request for testing:

I'm happy to announce the availability of a rebased patch series to
enhance KVM's guest debugging support as well as to add debug register
emulation. It was rebased because QEMU mainline recently accepted the
core of my corresponding bits and KVM has merged them over. A few
patches are still awaiting QEMU merge, and two of them are mandatory to
provide a clean foundation for the KVM changes - therefore this
intermediate step.

To test the series, checkout the kernel bits from

	git://git.kiszka.org/linux-kvm.git gdb-queue

and the user space part from

	git://git.kiszka.org/kvm-userspace.git gdb-queue

Early feedback welcome, also before the final submission. And if someone
could look into AMD/SVM implementation, this would also be great
(unfortunately, there is no customer need for it ATM, thus no resources).

Enjoy,
Jan

Would you mind posting the patches here, to make feedback easier for the
reviewers?

I was waiting for the first two of them getting merged into qemu, what
has happened yesterday, plus there was one open oddity that is
understood and fixed now as well. Will post them later today.
