io_uring not loadable in oralce arm kernel

[ppafan]

When I use fio with io_uring engine to test disk perfermance in Oracle Ampere server, it gives me error messages below, I think it's a kernel issue or something. Same install and usage on amd64 server works well.

fio: engine io_uring not loadable
fio: engine io_uring not loadable
fio: failed to load engine
fio: file:ioengines.c:89, func=dlopen, error=io_uring: cannot open shared object file: No such file or directory
