I'm afraid I don't understand what you are trying to say. This is the log for the
gicv3-ipi test:

$ cat logs/gicv3-ipi.log
timeout -k 1s --foreground 90s /usr/bin/qemu-system-aarch64 -nodefaults -machine
virt,gic-version=host,accel=kvm -cpu host -device virtio-serial-device -device
virtconsole,chardev=ctd -chardev testdev,id=ctd -device pci-testdev -display none
-serial stdio -kernel arm/gic.flat -smp 6 -machine gic-version=3 -append ipi #
-initrd /tmp/tmp.trk6aAcaZx
WARNING: early print support may not work. Found uart at 0x9000000, but early base
is 0x3f8.
PASS: gicv3: ipi: self: Interrupts received
PASS: gicv3: ipi: target-list: Interrupts received
PASS: gicv3: ipi: broadcast: Interrupts received
SUMMARY: 3 tests

The warning is because I forgot to reconfigure the tests with --vmm=qemu.

Would you mind pointing out what you think is ambiguous?

Thanks,

Alex
