[Qemu-devel] [kvm-unit-tests PATCH v5 00/11] My current MTTCG tests

["Alex Bennée" <alex.bennee@linaro.org>]

Hi,

This is the current state of my MTTCG tests based on the KVM's unit
testing framework. The earlier patches in the series have already been
reviewed and will (with the exception of the emacs patch) be making
their way upstream.

There are a couple of addition to library functions:
  - printf %u suppport
  - flush_tlb_page for arm and arm64
  - a generic prng from CCAN

The two actual tests are:
  - tlbflush-test
  - barrier-test

The latter barrier test hangs the current -v6 MTTCG patch set in both
"excl" and "acqrel" modes and will make a good torture test for
Alvise's atomic patch set. I suspect the load/store ordering issues
will show up better once tested on a weak-ordered backend. I'm open to
suggestions for other tests worth adding to show up the issues.
