Description 苟浩 uniontech_group 2022-12-06 17:58:39 UTC 
复现步骤：
$ mount -t resctrl resctrl /sys/fs/resctrl/
$ cd /sys/fs/resctrl
$ mkdir newlock
$ echo pseudo-locksetup > newlock/mode
bash: echo: write error: Invalid argument
$ cat info/last_cmd_status 
Unknown or unsupported mode

正常情况下应该给mode写入成功，或者如果硬件不支持的话，应该显示如下：
$ echo pseudo-locksetup > newlock/mode
bash: echo: write error: Invalid argument
$ cat info/last_cmd_status 
Pseudo-locking not supported
