This has taken quite a while to get right, but I think is getting
much better now.
There are several semi-related things here: multi-migration support,
bugfixing, adding powernv machine, expanding and adding test cases.
But I found it easiest to leave it as one series. Multi-migration I
added when testing and debugging time migration issues in QEMU, and
that has grown to quite a size, I can try to split that out if
preferred.
Since v4:
- Multi migration now seems quite solid, I haven't broken it. Arm64
migration regression reported by Shaoqin is fixed, it was due to an exit
status getting lost.
- Several other small migration fixes and cleanups that poppedup in
testing.
- More complete SMP support including IPI for pseries and powernv.
- Made powernv a first-class citizen that can do run_tests.sh unit
tests (with machine option).
- More polished, quiet warnings, skip unsupported tests, etc.
- Fix several powerpc bugs that got exposed (.got, stack backtrace,
stack alignment).
- Added a bunch more tests I've been accumulating, atomics, smp,
timebase, interrupts.
Note the arm64 psci cpu-on test is flakey with/without this series.
Thanks,
Nick
