Hi...
I'd like to know if there's a way to set a system-global flag in user
mode that can be read in kernel mode. Specifically, I'd like to know
if a NAPI poll function is being executed during a system call that I
wrote, so the idea is to set the flag before the system call is
invoked, clear it when it returns and test it during the poll function.
This is for testing purposes only, so any quick'n'dirty trick will do.
Other ideas for achieving the same functionality are also welcome (as
long as the overhead is low).
Ehm, since you implement your own syscall, I think it's possible to add
one more parameter to it, e.g:
my_syscall(param1, param2, myflag)
What do you think?
regards,
Mulyadi
