[kvm-unit-tests PATCH v2 3/4] arm64: enable its-migration tests for TCG

With the support for TCG emulated GIC we can also test these now. Signed-off-by: Alex Bennée Cc: Shashi Mallela --- arm/unittests.cfg | 2 -- 1 file changed, 2 deletions(-) diff --git a/arm/unittests.cfg b/arm/unittests.cfg index f776b66..1a39428 100644 --- a/arm/unittests.cfg +++ b/arm/unitte

[kvm-unit-tests PATCH v2 0/4] enable LPI and ITS for TCG

This is a companion to Shashi's series enabling LPI and ITS features for QEMU's TCG emulation. This is part of our push for a sbsa-ref platform which needs a more modern set of features. Since the last posting this is now at v3: From: Shashi Mallela Subject: [PATCH v3 0/8] GICv3 LPI and ITS f

[kvm-unit-tests PATCH v2 2/4] scripts/arch-run: don't use deprecated server/nowait options

The very fact that QEMU drops the deprecation warning while running is enough to confuse the its-migration test into failing. The boolean options server and wait have accepted the long form options for a long time. Signed-off-by: Alex Bennée Cc: Shashi Mallela --- scripts/arch-run.bash | 4 ++--

[kvm-unit-tests PATCH v2 4/4] arm64: split its-migrate-unmapped-collection into KVM and TCG variants

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

[kvm-unit-tests PATCH v2 1/4] arm64: remove invalid check from its-trigger test

While an IRQ is not "guaranteed to be visible until an appropriate invalidation" it doesn't stop the actual implementation delivering it earlier if it wants to. This is the case for QEMU's TCG and as tests should only be checking architectural compliance this check is invalid. Signed-off-by: Alex

[kvm-unit-tests RFC PATCH] arm64: split pmu tests into tcg/kvm variants

QEMU is able to give a counter for instructions retired under TCG but you need to enable -icount for it to work. Split the tests into kvm/tcg variants to support this. [AJB: I wonder if the solution is to have a totally separate unittests.cfg for TCG mode here?] Signed-off-by: Alex Bennée --- a
