Node vs Threads in scheduling

Hi, How does the scheduling state of a thread differ from that of its corresponding node in a scheduler? How does thread helping work? Since a thread only has one node per scheduler instance, how do things happen? Also, can someone please explain how the thread could in the ready state while the

Thank you for your answer. The current SMP schedulers maintain a list of scheduled nodes. These are > nodes which have an allocated processors. Nodes which are ready (they > don't have an allocated processor) are maintained in chains, tables of > chains, or red-black trees depending on the impleme

Regarding idle thread in scheduling

Hi, Can someone please tell me what is the logic behind using functions like _Scheduler_Discard_idle_thread and _Scheduler_Release_idle_thread and other similar functions dealing with idle threads? Reading the code is hard without having an idea about the motivation of the functions. Thanks, Ric

[PATCH] rtems: Use unique option values

The RTEMS_BARRIER_AUTOMATIC_RELEASE and RTEMS_BINARY_SEMAPHORE options had the same value. In order to better detect a misuse of option values (for example using RTEMS_BINARY_SEMAPHORE for rtems_barrier_create()), the options should have unique values. Close #4054. --- cpukit/include/rtems/rtems
