Hello,
I'm experiencing some issue trying to set block thread priorities.
I discovered that my USRP is not able to set thread priorities since the
function pthread_setschedparam(pthread_self(), policy, &sp); fails.
Therefore, I tryed to test a simple block (whatever), inserting the core
affinity to a processor (e.g. CPU 0) directly in the block GUI,
then, in the block constructor I set the thread priority with
gr::thread::set_thread_priority(gr::thread::get_current_thread_id(),99);
The priority value is retrieved in the work function, and tells that the
thread priority is set to 0 (wrong).
I suspect that there is a limitation somewhere (probably in the linux
kernel or in some configuration file), I tryed it on another machine
without problems (all works correctly).
Can you help me?
