Hi, I have studied the rcu torture test recently. I am also interested in this topic. But I can't open [1]: https://owww.molgen.mpg.de/~pmenzel/allmodconf-Make.out.txt [2]: https://owww.molgen.mpg.de/~pmenzel/rcutorture-log.txt >From your email, It seems that include/generated/autoconf.h is not generated in the early stage of kernel build. Could you try following one by one if you have time ;-) after invoking each of the following commands, we can examine if include/generated/autoconf.h is created in another terminal, and if it is created, we can try the next command. tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE01" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE02" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE03" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE04" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE05" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE06" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE07" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE08" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE09" tools/testing/selftests/rcutorture/bin/kvm.sh --buildonly --configs "TREE10" I am a beginner at learning RCU ;-) I may not be right. Apologize in advance if I am not right.
