Paolo or Radim,

Please do a pull from my kvm-ppc-next-5.1-1 tag to get a PPC KVM
update for 5.1.  There is nothing major in there, just a collection of
bug fixes and minor improvements.

Thanks,
Paul.

Michael Ellerman already applied this
and I see it in linux-next, though.

Oh well, I didn't notice that, but it doesn't matter anyway because
the powerpc/next branch merges cleanly with my kvm-ppc-next branch
(and if it didn't, Stephen Rothwell would have let us know).

Yeah, git will merge it nicely, but
please let me state my two cents.

I like to see "applied" email from a maintainer.

Michael replied to me (and ML) when he applied my patch.

I noticed you had also picked it up only after I saw your pull request.

If you collect patches silently, nobody is given a chance to point out
when something not nice happens.

I normally do that too, though I do it manually (I think Michael has
an automated process), and this time my collecting of patches got
delayed because I was chasing a nasty memory corruption bug.

I have asked Michael to cc me when he applies a KVM patch to his
tree in future.

Paul.

[GIT PULL] Please pull my kvm-ppc-next-5.1-3 tag

[Paul Mackerras]

Paolo & Radim,

Immediately after I sent my previous pull request, I saw that Suraj
had posted a patch that advertises a new mitigation for one of the
spectre vulnerabilities to userspace.  The code for the host to know
about and use this new mitigation went into 4.19.  Since the patch is
low-risk and security-related, I would like to get it into 5.1.  With
this patch and a related QEMU patch, guests will be able to use this
new mitigation on machines that support it.

So, please do a pull from my kvm-ppc-next-5.1-3 tag to get this
commit.  (If you haven't already pulled the 5.1-2 tag then you will
get the compile fix as well, of course.)

Thanks,
Paul.

Ping?

Also, if you have sent a pull request to Linus for the 5.1 merge
window, I missed it.  Has that been sent?

Pulled now, thanks.

[GIT PULL] Please pull my kvm-ppc-next-5.2-1 tag

[Paul Mackerras]

Paolo or Radim,

Please do a pull from my kvm-ppc-next-5.2-1 tag to get a PPC update
for 5.2.  The main new feature here is that we can now let guests
access the POWER9 XIVE interrupt controller directly for things like
acknowledge, EOI, enable and disable on interrupts, rather than
requiring guests to do hypercalls for these operations.

I have merged in the topic/ppc-kvm branch from the powerpc tree
because one of the patches there is a prerequisite for the XIVE patch
series.  That's why there are changes to arch/powerpc/kernel in the
diffstat.

Stephen Rothwell noted a conflict between my tree and the kvm-arm tree
because we have both allocated new capability numbers.

The XIVE patch series also modifies generic KVM code to add mmap and
release methods on KVM devices.

Thanks,
Paul.

[GIT PULL] Please pull my kvm-ppc-next-5.2-1 tag

[Paul Mackerras]

Paolo or Radim,

Please do a pull from my kvm-ppc-next-5.2-1 tag to get a PPC update
for 5.2.  The main new feature here is that we can now let guests
access the POWER9 XIVE interrupt controller directly for things like
acknowledge, EOI, enable and disable on interrupts, rather than
requiring guests to do hypercalls for these operations.

I have merged in the topic/ppc-kvm branch from the powerpc tree
because one of the patches there is a prerequisite for the XIVE patch
series.  That's why there are changes to arch/powerpc/kernel in the
diffstat.

Stephen Rothwell noted a conflict between my tree and the kvm-arm tree
because we have both allocated new capability numbers.

The XIVE patch series also modifies generic KVM code to add mmap and
release methods on KVM devices.

Thanks,
Paul.

PPC KVM update for 5.2

* Support for guests to access the new POWER9 XIVE interrupt controller
  hardware directly, reducing interrupt latency and overhead for guests.

[GIT PULL] Please pull my kvm-ppc-next-5.2-2 tag

[Paul Mackerras]

Paolo, Radim,

I have added 3 more commits to my kvm-ppc-next tree, for various fixes
that have come in recently.  There is one bug fix, one spelling fix,
and one commit that removes some code that does nothing.  The net
result is 12 fewer lines of code in the kernel. :)

If you pull this tag and not the earlier kvm-ppc-next-5.2-1 tag, you
might want to include the text from that tag in the commit message.
That text is:

"
PPC KVM update for 5.2

* Support for guests to access the new POWER9 XIVE interrupt controller
  hardware directly, reducing interrupt latency and overhead for guests.

* In-kernel implementation of the H_PAGE_INIT hypercall.

* Reduce memory usage of sparsely-populated IOMMU tables.

* Several bug fixes.
"

Thanks,
Paul.

Pulled, thanks.  Sorry for not following up on this before, my
travelling schedule was horrible for this merge window.

[GIT PULL] Please pull my kvm-ppc-next-5.4-1 tag

[Paul Mackerras]

Paolo or Radim,

Please do a pull from my kvm-ppc-next-5.4-1 tag to get a PPC KVM
update for 5.4.  There is not a lot this time, mostly minor fixes and
some prep for future patch series, plus a series that fixes a race
condition in the XIVE interrupt controller code where interrupts could
arrive after free_irq() and cause hangs and crashes in the host.

The XIVE fix touches both PPC KVM and generic powerpc code, so Michael
Ellerman put it in his topic/ppc-kvm branch and I have merged that
branch into my kvm-ppc-next branch.

Thanks,
Paul.

Pushed to kvm/queue for now.  It may take a couple days after I get
back, before I test all the pending x86 patches and push out to kvm/next.

[Paul Mackerras]

Paolo,

Please do a pull from my kvm-ppc-next-5.5-2 tag to get two more
commits which should go upstream for 5.5.  Although they are in my
kvm-ppc-next branch, they are actually bug fixes, fixing host memory
leaks in the XIVE interrupt controller code, so they should be fine to
go into v5.5 even though the merge window is now open.

Thanks,
Paul.

Yes, of course (I have even accepted submaintainer pull request for new
features during the first week of the merge window, so not a problem at
all).

I'll send my pull request to Linus shortly.

In that case, I have a patchset from Bharata Rao which is just now
ready to go in.  It has been around for a while; Bharata posted v11
yesterday, and we would really like it to go in v5.5, but I thought we
were too late.  If you're OK with taking it at this stage then I'll
send you another pull request.

Thanks,
Paul.

This may take a couple days because I am running a lot of tests on a
very scary x86 5.6 update, but I have already pulled it locally.

[Paul Mackerras]

Paolo,

I have a second KVM PPC update for you.  I have added two more commits
which are both one-line fixes.  One is a compile warning fix and the
other fixes a locking error where we could incorrectly leave a mutex
locked when an error occurs.

Thanks,
Paul.

[GIT PULL] Please pull my kvm-ppc-next-5.8-1 tag

[Paul Mackerras]

Hi Paolo,

Please do a pull from my kvm-ppc-next-5.8-1 tag to get a PPC KVM
update for 5.8.  It's a relatively small update this time.  Michael
Ellerman also has some commits in his tree that touch
arch/powerpc/kvm, but I have not merged them here because there are no
merge conflicts, and so they can go to Linus via Michael's tree.

Thanks,
Paul.

Thanks.

Are you planning to send Linus another pull request for this merge
window, with this stuff in it?

[GIT PULL] Please pull my kvm-ppc-next-5.9-1 tag

[Paul Mackerras]

Paolo,

Please do a pull from my kvm-ppc-next-5.9-1 tag to get a PPC KVM
update for 5.9.  It's another relatively small update this time, the
main thing being a series to improve the startup time for secure VMs
and make memory hotplug work in secure VMs.

Thanks,
Paul.

More or less; I was on vacation so I did miss it.  But I was planning
anyway to send ARM and PPC on a second pull request, I would have
noticed it when preparing it (as I did now :)).

Paolo,

Please do a pull from my kvm-ppc-next-5.10-1 tag to get a PPC KVM
update for 5.10.  This is a small update with just some bug fixes and
no new features.

Thanks,

Paolo,

Please do a pull from my kvm-ppc-next-5.12-1 tag to get a PPC KVM

support for the second data watchpoint in POWER10.
