tools/virtio: Fix arm64 ringtest compilation error

2023-06-08T19:43:08+00:00

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 In file included from ring.c:10: main.h: In function ‘busy_wait’: main.h:99:21: warning: implicit declaration of function ‘assert’ [-Wimplicit-function-declaration] 99 | #define cpu_relax() assert(0) | ^~~~~~ main.h:107:17: note: in expansion of macro ‘cpu_relax’ 107 | cpu_relax(); | ^~~~~~~~~ main.h:12:1: note: ‘assert’ is defined in header ‘’; did you forget to ‘#include ’? 11 | #include +++ |+#include 12 | main.h: At top level: main.h:143:23: error: expected ‘;’ before ‘void’ 143 | static __always_inline | ^ | ; 144 | void __read_once_size(const volatile void *p, void *res, int size) | ~~~~ main.h:158:23: error: expected ‘;’ before ‘void’ 158 | static __always_inline void __write_once_size(volatile void *p, void *res, int size) | ^~~~~ | ; make: *** [: ring.o] Error 1 Signed-off-by: Rong Tao Message-Id: Signed-off-by: Michael S.

tools/virtio: remove smp_read_barrier_depends()

2022-12-28T10:28:11+00:00

This gets rid of the last references to smp_read_barrier_depends() which for the kernel side was removed in v5.9. The serialization required for Alpha is done inside READ_ONCE() instead of having users deal with it. Simply use a full barrier, the architecture does not have rmb in the first place.
