[Qemu-devel] target/arm: kvm-unit-tests gicv2 test failures on tcg

[Andrew Jones]

Hi TCG GIC developers,

There are a few gicv2 test failures when running over TCG that we don't
see when running over KVM. I don't believe these are regressions - I'm
pretty sure they've been failing since Andre first introduced the tests.
I'm just pointing them out now in case anybody would like to look into
them:

  $ git clone git://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
  $ cd kvm-unit-tests
  $ ./configure --arch=arm64 --cross-prefix=aarch64-linux-gnu-
  $ make -j
  $ export QEMU=/path/to/qemu-system-aarch64
  $ ./run_tests.sh -g gic
  $ grep FAIL logs/gic*
  logs/gicv2-mmio-3p.log:FAIL: gicv2: mmio: ITARGETSR: bits for 5 non-existent 
CPUs masked
