Use the following command to run: ./kvm.sh --qemu-cmd qemu-system-aarch64 Signed-off-by: Lihao Liang --- The max CPUs supported by qemu machine 'virt' is 8 so the value of CONFIG_NR_CPUS in some test configuration files needs to be adjusted. tools/testing/selftests/rcutorture/bin/functions.sh | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/rcutorture/bin/functions.sh b/tools/testing/selftests/rcutorture/bin/functions.sh index 07a1377..5ffe4fe 100644 --- a/tools/testing/selftests/rcutorture/bin/functions.sh +++ b/tools/testing/selftests/rcutorture/bin/functions.sh @@ -136,6 +136,9 @@ identify_boot_image () { qemu-system-x86_64|qemu-system-i386) echo arch/x86/boot/bzImage ;; + qemu-system-aarch64) + echo arch/arm64/boot/Image + ;; *) echo vmlinux ;; @@ -185,7 +188,14 @@ identify_qemu_append () { then echo root=/dev/sda else - echo console=ttyS0 + case "$1" in + qemu-system-aarch64) + echo console=ttyAMA0 + ;; + *) + echo console=ttyS0 + ;; + esac fi } @@ -197,6 +207,9 @@ identify_qemu_args () { case "$1" in qemu-system-x86_64|qemu-system-i386) ;; + qemu-system-aarch64) + echo -M virt -cpu host + ;; qemu-system-ppc64) echo -enable-kvm -M pseries -nodefaults echo -device spapr-vscsi @@ -257,6 +270,9 @@ specify_qemu_cpus () { qemu-system-x86_64|qemu-system-i386) echo $2 -smp $3 ;; + qemu-system-aarch64) + echo $2 -smp $3 + ;; qemu-system-ppc64) nt="`lscpu | grep '^NUMA node0' | sed -e 's/^[^,]*,\([0-9]*\),.*$/\1/'`" echo $2 -smp cores=`expr \( $3 + $nt - 1 \) / $nt`,threads=$nt -- 2.7.4
