| H A D | main.h | 57380fd1 Wed May 24 07:31:24 CDT 2023 Rong Tao <rongtao@cestc.cn> tools/virtio: Fix arm64 ringtest compilation error
Add cpu_relax() for arm64 instead of directly assert(), and add assert.h
header file. Also, add smp_wmb and smp_mb for arm64.
Compilation error as follows, avoid __always_inline undefined.
$ make
cc -Wall -pthread -O2 -ggdb -flto -fwhole-program -c -o ring.o ring.c
