It is caused by wrong finding in 2 cross tools for arm. And has been fixed. Thanks. Regarding to the vhost build issue itself, it has gone in latest vhost/linux-next. The cause is the code kbuild captured didn't have patch " vhost: factor out IOTLB " which introduce linux/vhost_iotlb.h at that moment. So just ignore this issue since the missed patch has been added in latest vhost/linux-next. > > >> >> If you fix the issue, kindly add following tag >> Reported-by: kbuild test robot <lkp@xxxxxxxxx> >> >> All errors (new ones prefixed by >>): >> >> In file included from include/linux/virtio.h:12, >> from include/linux/virtio_config.h:7, >> from include/uapi/linux/virtio_net.h:30, >> from include/linux/virtio_net.h:6, >> from net//packet/af_packet.c:82: >>>> include/linux/vringh.h:18:10: fatal error: linux/vhost_iotlb.h: No >>>> such file or directory >> 18 | #include <linux/vhost_iotlb.h> >> | ^~~~~~~~~~~~~~~~~~~~~ >> compilation terminated. >> >> vim +18 include/linux/vringh.h >> >> > 18 #include <linux/vhost_iotlb.h> >> 19 #include <asm/barrier.h> >> 20 > > >I can hardly believe it can't work. > >I get > ># file include/linux/vringh.h >include/linux/vringh.h: C source, ASCII text > >So this looks like a false positive to me? > >Thanks > > >> >> --- >> 0-DAY CI Kernel Test Service, Intel Corporation >> https://lists.01.org/hyperkitty/list/kbuild-all@xxxxxxxxxxxx
