Fw: Scheduling

[z f]

in RTEMS POSIX API User’s Guide says rtems support 4 policy .my question is: assume I want to use FIFO for thread scheduling in rtems .when and how I should make change during config.

rtems supports multithread and should have a policy to scheduling.is it right?

In 4.10 and older, there is one scheduling algorithm which
can be impacted by use of task/thread priority, preemption settings
and timeslice settings.

In the git head, you can select alternative scheduling algorithms
as documented here:
