Hello Henry, Thank you for you reply! The reason I patch RT to colinux is I want to make a RTOS simulation using colinux. The real "real time" is not so critical, maybe an acceptable latecy is OK This is also why I use "SCHED_FIFO", because the "FIFO" mode most fit the RTOS scheduling . I used colinux just for a cross-compiling environment , The "RTOS simulation" is my new idea, I'm now sure whether it is possible to achieve a 50ms delay using colinux. I have some other questions: - what 's the kernel latecy of the "PREEMPT colinux kernel" in the worst case? - can colinux get an occupancy rate of 50% if the linux task reach the maximum level? Can the run time of the colinux kernel be guaranteed (50%) if the windows is busy? |
