[kvm-unit-tests PATCH 00/32] powerpc improvements

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is the same familiar set of powerpc patches, it's taken a
while to get them merged. And unfortunately they keep growing
with fixes and new tests.

This goes on top of the previous migration and other core
patches. Full tree can be found here.

I have tried to test all combinations of KVM and TCG for P8/9/10
and powernv. There are a small number of failures, some due to
bugs in TCG, QEMU, and KVM. I don't want to drop such test cases
but xfail doesn't quite work because it will start failing if we
fix implementation to now work AFAIKS. If there is concern about
that, then maybe we could add a known-failure type of report that
can document the reason and not fail the entire group of tests.

Since last posting, this adds several fixes to the start of the
series, fixes a bunch of bugs in the SPRs and other tests that
Joel and Thomas raised.  Tidied up the new new SMP support and
fixed a couple of issues there. Added MMU, usermode support,
add atomics, timebase, PMU tests, and removes the ppc64
subdirectories.

Thanks,
Nick
