While debugging check-acceptance failures I found an instability in
the mips64el test case. Briefly the test case:

  retry.py -n 100 -c -- ./mips64el-softmmu/qemu-system-mips64el \
    -display none -vga none -serial mon:stdio \
    -machine malta -kernel ./vmlinux-4.7.0-rc1.I6400 \
    -cpu I6400 -smp 8 -vga std \
    -append "printk.time=0 clocksource=GIC console=tty0 console=ttyS0 panic=-1" \
    --no-reboot

Reports about a 9% failure rate:

  Results summary:
  0: 91 times (91.00%), avg time 5.547 (0.45 varience/0.67 deviation)
  -6: 9 times (9.00%), avg time 3.394 (0.02 varience/0.13 deviation)
  Ran command 100 times, 91 passes

When re-run with "--accel tcg,thread=single" the instability goes
away.

  Results summary:
  0: 100 times (100.00%), avg time 17.318 (249.76 varience/15.80 deviation)
  Ran command 100 times, 100 passes

Which seems to indicate there is some aspect of the MIPS MTTCG fixes
that has been missed. Ideally we would fix that but I'm afraid I don't
have time to investigate and am not super familiar with the
architecture anyway.

I've disabled all the mips guests as I assume it's a fundamental
synchronisation primitive that is broken but I haven't tested them all
(there are a lot!).

I confirm, in my notes I use this option with -smp with the following cpus:
- mips64dspr2
- I6400

I am not sure the 32-bit targets are affected.
Maybe we can keep it enabled here?

For code below for 5.0 (64-bit targets):

Alex, following up Philippe's hint, do you see failures while using
32-bit targets?

Thanks,

Thank for the findings!

Could you perhaps attach or link to "retry.py"?

Did you run this particular test for the first time now, or it used to
pass before?

Thanks,
Aleksandar

Sure - it's just a noddy python script which I use for repeated testing:

  https://github.com/stsquad/retry

I only noticed it since it was added to check-acceptance and has been
flakey since added I think.
