Paolo or Radim,
Please do a pull from my kvm-ppc-next-4.17-1 tag to get a PPC KVM
update for the 4.17 merge window. What's in here is a series that
improves the radix page fault handler for POWER9 systems and makes it
use the generic __gfn_to_pfn_memslot() function. At this stage I am
just using that function as-is without the changes we discussed some
time ago; that can be optimized in future.
There are two other series that affect PPC KVM and also other powerpc
code. Michael Ellerman has put them in the topic/ppc-kvm branch in his
powerpc tree and merged them into his next branch. I have not merged
that topic branch into my kvm-ppc-next branch because there were no
conflicts to resolve and so those changes might as well just go in
through Michael's tree. There was a series that adds hypervisor
assistance for transactional memory, allowing KVM guests to use TM on
POWER9 systems, and a series that disables use of data watchpoints on
POWER9 because of hardware bugs.
Thanks,
Paul.

Paolo or Radim,
Please do a pull from my kvm-ppc-next-4.18-1 tag to get a PPC KVM
update for 4.18. This is a reasonably large update; it includes two
series from Simon Guo, to reimplement the MMIO instruction emulation
and to add transactional memory support to PR KVM, plus a series from
Nick Piggin to improve radix page table handing, plus quite a few
other patches.
I have merged in Michael Ellerman's topic/ppc-kvm branch to get some
commits that affect arch/powerpc and were needed as prerequisites for
the KVM patches here.
Thanks,
Paul.

Hi Paolo,
It seems my previous pull request of 4 June might have got missed, or
buried in your inbox. In any case, I have added some more fixes to my
kvm-ppc-next branch, and if you could pull the kvm-ppc-next-4.18-2 tag
and push that to Linus for 4.18, that would be very much appreciated.
I have checked that this branch merges cleanly with Linus' current
tree and boots and runs KVM successfully on POWER8 and POWER9.
This update is quite large; it includes a series to reimplement how we
do MMIO instruction emulation to use more of the common powerpc kernel
infrastructure, a series to improve radix page table handling on
POWER9, a series to add transactional memory support to PR KVM, plus
quite a few bug fixes.
Thanks,
Paul.

Paolo or Radim,
Please do a pull from my kvm-ppc-next-4.19-1 tag to get a PPC update
for 4.19. There is not much in there, just some code cleanups and bug
fixes.
Michael Ellerman also has some changes that touch arch/powerpc/kvm in
his topic/ppc-kvm branch, which he has merged into his next branch. I
have not pulled them into my tree since there are no conflicts with
the changes in my kvm-ppc-next branch.
Thanks,
Paul.

Paolo or Radim,
Please do a pull from my kvm-ppc-next-4.20-1 tag to get a PPC KVM
update for 4.20. There is one big new feature here, which is nested
virtualization support for radix guests on POWER9, plus a few other
fixes and improvements.
A lot of the commits here are also going to be merged in the powerpc
tree via the topic/ppc-kvm branch, in order to reduce conflicts
between the powerpc tree and the kvm tree.
Stephen Rothwell noted that there is a conflict between my
kvm-ppc-next tree and the kvm-arm tree, in that we have both allocated
the next free capability number (160). It would be nice to get a
stable allocation for the new capability that I need (one which
reports/enables nested virtualization support for the HV KVM module)
so that the necessary QEMU patches can be submitted.
Thanks,
Paul.

KVM: PPC: Book3S HV: Add NO_HASH flag to GET_SMMU_INFO ioctl result (2018-10-09 16:14:54 +1100)
----------------------------------------------------------------
PPC KVM update for 4.20.
The major new feature here is nested HV KVM support. This allows the
HV KVM module to load inside a radix guest on POWER9 and run radix
guests underneath it. These nested guests can run in supervisor mode
and don't require any additional instructions to be emulated, unlike
with PR KVM, and so performance is much better than with PR KVM, and
is very close to the performance of a non-nested guest. A nested
hypervisor (a guest with nested guests) can be migrated to another
host and will bring all its nested guests along with it. A nested
guest can also itself run guests, and so on down to any desired depth
of nesting.
Apart from that there are a series of updates for IOMMU handling from
Alexey Kardashevskiy, a "one VM per core" mode for HV KVM for
security-paranoid applications, and a small fix for PR KVM.

Since you sent the pull request first, you get to use 160. :)

Paolo or Radim,
Please do a pull from my kvm-ppc-next-4.20-2 tag to get a second
update for PPC KVM to go into 4.20. This is a very small update, with
only two commits. It turned out to be necessary to disable the new
nested HV KVM feature on early POWER9 chips that need a particular
hardware bug workaround which the new guest entry path doesn't
implement, so one commit does that. The other commit is an
optimization for clearing IOMMU tables when doing PCI pass-through.
The second commit touches drivers/vfio/vfio_iommu_spapr_tce.c as well
as arch/powerpc/kvm code. That should be OK, as Alexey Kardashevskiy
is pretty much the only person that touches that file. However, if
you would prefer that part of the change to go via another tree, let
me know and I'll re-do the pull request without that commit (or you
can just merge the other commit on its own).
Thanks,
Paul.

Paolo or Radim,
Please do a pull from my kvm-ppc-next-4.21-1 tag to get a PPC KVM
update for 4.21. The main new thing this time is an improvement to
the nested HV KVM code so that if you have a nested hypervisor that
has a PCI device which is actually emulated by the level 0 hypervisor,
level 1 can pass that through to level 2 using VFIO and the accesses
to the device by level 2 will be emulated by level 0 and the results
passed down to level 2 correctly.
Thanks,
Paul.

Paolo or Radim,
Thanks for pulling the previous set of commits for 4.21. Suraj
Jitindar Singh has just fixed several bugs in the page dirty tracking
for nested guests, and it seems worth while to try to get his series
in for 4.21. So please do a pull from my tree again to get this patch
series.
Thanks,
Paul.
