Absolutely, the realtime priority is applicable to the RT policies FIFO and RR which varies from 0-99. We do have the 40 as a count of the non real time process priority for BATCH, OTHER policies which varies from 0-39 not from 100 to 139.
What is real-time priority in Linux?
Priority value — The priority value is the process’s actual priority which is used by the Linux kernel to schedule a task. In Linux system priorities are 0 to 139 in which 0 to 99 for real-time and 100 to 139 for users. Nice value — Nice values are user-space values that we can use to control the priority of a process.
Which processes have the highest priority?
A process’ priority can range between 0 (lowest priority) and 127 (highest priority). User mode processes run at lower priorities (lower values) than system mode processes. A user mode process can have a priority of 0 to 65, whereas a system mode process has a priority of 66 to 95.
