Ah-ha! I wasn't seeing it mentioned in dmesg (it should appear along with PAN, etc, yes?) but I guess I need a newer QEMU: $ qemu-system-aarch64 --version QEMU emulator version 3.1.0 (Debian 1:3.1+dfsg-2ubuntu3.1) I will go build QEMU myself! :) -- = Kees Cook _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
