[kvm-unit-tests PATCH 0/3] tcg is becoming a first class citizen

[kvm-unit-tests PATCH 0/3] tcg is becoming a first class citizen

[Andrew Jones]

At least on the ARM side of things we're making sure unit tests can
be used for [MT]TCG, as well as for KVM. This series adds support to
unittests.cfg to allow us to specify kvm vs. tcg, as not all tests
will be able to run on both. The first patch is a repost of one of
Alex's pending patches, as the 3rd patch depends on it. The 3rd patch
obsoletes/replaces Alex's pending "arm/run: introduce usingkvm var
and use it" patch.

Alex Bennée (1):
  configure: emit HOST=$host to config.mak

Andrew Jones (2):
  run_tests: pass test name to run script
  arm/run: use ACCEL to choose between kvm and tcg

This is useful information for the run scripts to know, especially if
they want to drop to using TCG.

[kvm-unit-tests PATCH 3/3] arm/run: use ACCEL to choose between kvm and tcg

[Andrew Jones]

Inspired by a patch by Alex Bennée. This version uses a new
unittests.cfg variable and includes support for DRYRUN.

Signed-off-by: Andrew Jones <drjones@redhat.com>

Another difference with Alex's patch is we no longer output
'Running with TCG', as I don't think it's necessary. The
command line captures that, and the whole point of the patch
is to silence the '"kvm" accelerator not found.' messages
anyway.

I forgot to actually test mkstandlone... The dryrun stuff
in this patch isn't sufficient for the new unittests variable.
I've worked up a v2 and will post the series again shortly.

Yeah that makes sense.

I see your re-posting so I'll do a full review then. Is there a branch I
can re-base my stuff on top of for now?

OK, https://github.com/rhdrjones/kvm-unit-tests/commits/staging has been
updated. BTW, that branch is anything but stable. It'll get a rebase
anytime upstream master or next is updated, and iff neither of those are
a sufficient base (so not only is it unstable, but it could go stale...)
Hopefully atm it's useful for you to rebase on though.

Thanks,
