Thank,

I've tried to build Linux (5.2.1) with the configuration found in
arch/arm64/configs/defconfig
and yes Symbol: ARM_PSCI_FW [=y] in this configuration.
But still "halt -f" (busybox v1.31.0) doesn't make QEMU
(qemu-systme-aarch64 version qemu-3.1.0-9.fc30) exit.
(and again machine=virt).

Best regards,
