IBM business has changed focus and pseries/KVM will be less in
the spotlights. Nevertheless, there is a large code base we want
to keep running and not break. Migration compatibility is the
most complex part of it. I hope we will be able to automate some
of the non-regression tests RedHat/IBM have. Not an easy part
I admit.


There are plenty of contributors who help on very large parts
of QEMU-PPC.

Richard and the Eldorado team are watching closely instruction
implementation,
Mark is doing the same for MAC machines,
Balaton for 44x and 46x and associated machines.
Thomas showed he could bring back from the dead any forgotten board,
Alex Graf still admins the qemu-ppc mailin list.
It was nicely hooked to patchwork by the OzLabs recently :

    https://patchwork.ozlabs.org/project/qemu-ppc/list/

we might add some simple automation on the received patches,
"does the patch apply ?" for instance. Anyhow, it's an easy way
to share the review between people.

Daniel, Bharata, Fabiano, Nick, You and Greg for pseries, and
Alexey, for SLOF+VOF also. I am still around for PowerNV, XIVE, XICS.

Christophe is doing his best to keep alive Linux ppc405.

Michael does kernel CI testing on all these platforms :

    https://github.com/linuxppc/ci-scripts/tree/master/scripts/boot

Guenter also does :

    https://github.com/groeck/linux-build-test/tree/master/rootfs/ppc

and skiboot :

    https://github.com/open-power/skiboot/tree/master/opal-ci

GitLab does even more.

and we have Philippe, always here to make sure every grain of sand
has been examined.

We don't feel alone :)

Thanks for the time and assistance for all these years. Pseries
and PowerNV would not be in such a good shape without all the
efforts you have put into them.

I suppose emulation will take a larger part of our time now since
it is largely used for pseries/powernv development in IBM. We will
see how that goes.
