Task Switching in Linux
Quoted 7 lines · Jaswinder Singh
In Linux , If we assume that there are only 2 tasks A and B and both are equal , this is correct or not :-
TASK A -> schedule ->
switch_to-> TASK B -> schedule ->switch_to-> schedule ->switch_to-> TASK A.
If you mean "->" as "specifically calls" then that looks like cooperative multi-tasking, which is what kernel threads AND the Linux userland scheduler do. If an in-kernel thread doesn't call schedule, it keeps the CPU. See the H3rL stuff in ftp://linux01.gwdg.de/pub/cLIeNUX/interim
