Subject: [kvm-unit-tests PATCH v2 4/4] arm64: split its-migrate-unmapped-collection into KVM and TCG variants
Date: Tue, 25 May 2021 18:26:28 +0100	[thread overview]
Message-ID: <20210525172628.2088-5-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210525172628.2088-1-alex.bennee@linaro.org>

When running the test in TCG we are basically running on bare metal so
don't rely on having a particular kernel errata applied.

You might wonder why we handle this with a totally new test name
instead of adjusting the append to take an extra parameter? Well the
run_migration shell script uses eval "$@" which unwraps the -append
leading to any second parameter being split and leaving QEMU very
confused and the test hanging. This seemed simpler than re-writing all
the test running logic in something sane ;-)
