200us 500us 500us\n\nThe deadline and period from task P1 are less than 1ms.\n\nIn order to achieve microsecond precision, we need to enable HRTICK feature\nby the next command:\n\n PC#echo \"HRTICK\"

\u003d 0.002526(2.526ms)\n\nThe correct runtime should be less than or equal to 200us at some point.\n\nThe problem is caused by a conditional judgment \"delta \u003e 10000\"\nin function start_hrtick_dl().\n\nBecause no hrtimer start up to control the rest of runtime\nwhen the reset of runtime is less than 10us.\n\nSo the process will continue to run until tick-period is coming.\n\nMove the code with the limit of the least time slice\nfrom hrtick_start_fair() to hrtick_start() because the\nEDF schedule class also needs this function in start_hrtick_dl().\n\nTo fix this problem, we call hrtimer_start() unconditionally in\nstart_hrtick_dl(), and make sure the scheduling slice won\u0027t be smaller\nthan 10us in hrtimer_start().\n\nSigned-off-by: Xiaofeng Yan
