ppc/xive queue:

Is there anything in there which should be picked up for
stable qemu branches?
May be the IBM simulation team can say ?
I think this would also require some testing before applying.
Which stable branch are you targeting ? 7.2 to 10.0 ?
There are currently 2 active stable branches, 7.2 and 10.0.
Both are supposed to be long-term maintenance. I think 7.2
can be left behind already.

Michael T.,
All of the XIVE fixes/changes originating from myself were made in an
effort to get PowerVM firmware running on PowerNV with minimal testing
of OPAL firmware. However, even with those fixes, running PowerVM on
PowerNV is still pretty unstable. While backporting these fixes would
likely increase the stability of running PowerVM on PowerNV, I do think
it could pose significant risk to the stability of running OPAL on
PowerNV. With that in mind, I think it's probably best if we did not
backport any of my own XIVE changes.
These seem to be interesting to have :
ppc/xive2: Fix treatment of PIPR in CPPR update
ppc/xive2: Fix irq preempted by lower priority group irq
ppc/xive: Fix PHYS NSR ring matching
ppc/xive2: fix context push calculation of IPB priority
ppc/xive2: Remote VSDs need to match on forwarding address
ppc/xive2: Fix calculation of END queue sizes
ppc/xive: Report access size in XIVE TM operation error logs
ppc/xive: Fix xive trace event output
?
Thanks,
