What is time quota for each thread with same priority when using SCHED_PRIO or SCHED_RR in Xilkernel?
1 ms or configurable?

Check the documentation for systmr_interval:
PARAM name = systmr_interval, type = int, default = 10, desc = "Specify the time interval for each kernel tick (in milliseconds). This controls the CPU budget for each process. If the timer is fit_timer, then this parameter is automatically determined";

I have problem regarding this issue.
I use microblaze and FIT as the system timer device but the it seems like the system interrupt does not function. I used PIT before (with power pc) and the threads were switching well. I have connect the FIT interrupt to the microblaze interrupt input...but the ticks didn't occur. No context switching happen. What steps did I miss?

In Software Platform Setting> OS n Lib>systmr_spec.. Set the systmr_interval = 5. I think you have already done that. Then clean the software first, then generate the library again. It should works then.

I download the bitstream directly to FPGA (using the download bitstream icon on xps)... and the result appear on the hyperterminal. It should print 123456789.
For 10ms; it prints 1234567
For 2ms; it prints 1234
then it will switch to another thread..and continues back at where it stops.
