Hello, Rich,
Thanks a lot for your kind help, now I could insert modules with command
arguments.
Also, I am still wondering if I could change some parameters during the
kernel module is running, such as pthread's period time. I think I may use
shared memory to pass these parameters into kernel, but not sure if this
way is safe ? Thank you again.
Kind regards,
Yuhong
