Now that strange arm64 hang is found to be QEMU bug, I'll repost.
Since arm64 requires Thomas's uart patch and it is worse affected
by the QEMU bug, I will just not build it on arm. The QEMU bug
still affects powerpc (and presumably s390x) but it's not causing
so much trouble for this test case.
I have another test case that can hit it reliably and doesn't
cause crashes but that takes some harness and common lib work so
I'll send that another time.
Since v4:
- Don't build selftest-migration on arm.
- Reduce selftest-migration iterations from 100 to 30 to make the
test run faster (it's ~0.5s per migration).
Since v3:
- Addressed Thomas's review comments:
- Patch 2 initrd cleanup unset the old variable in the correct place.
- Patch 4 multi migration removed the extra wait for "Now migrate the
VM" message, and updated comments around it.
- Patch 6 fix typo and whitespace in quiet migration support.
- Patch 8 fix typo and whitespace in migration selftest.
Since v2:
- Rebase on riscv port and auxvinfo fix was merged.
- Clean up initrd cleanup moves more commands into the new cleanup
function from the trap handler comands (suggested by Thomas).
- "arch-run: Clean up temporary files properly" patch is now renamed
to "arch-run: Fix TRAP handler..."
- Fix TRAP handler patch has redone changelog to be more precise about
the problem and including recipe to recreate it.
- Fix TRAP handler patch reworked slightly to remove the theoretical
race rather than just adding a comment about it.
- Patch 3 was missing a couple of fixes that leaked into patch 4,
those are moved into patch 3.
Thanks,
Nick
