Experiments with J-5.15.0-1058-realtime on bos02 ARM64 shows it will take:
  * 5m4.261s
  * 5m8.267s
  * 5m9.418s
  * 5m11.923s
  * 5m4.715s
  * 5m17.411s
  * 5m11.225s
  * 5m7.947s
  * 5m16.900s
  * 5m28.553s

In this case we will need LTP_TIMEOUT_MUL=3 to bump the LTP timeout to 5m30s (or even set it to 4).
Thoughts?


BTW I have a hint added for F-5.15.0-102-generic-64k.

  New

Bug description:
  For the 2024.03.04 cycle and s2024.02.05 cycle, ubuntu_ltp
  sched:starvation failed on j/realtime on bos2 region. Switching it to
  bos1 region allowed it to pass during the s2024.02.05 cycle.

  Examples of failure from 2024.03.04:

  tst_test.c:1741: TINFO: LTP version: 20230929-407-g58aa31f55
  tst_test.c:1625: TINFO: Timeout per run is 0h 00m 30s
  starvation.c:57: TPASS: sched_setaffinity(0, sizeof(mask), &mask) returned 0
  tst_test.c:1633: TINFO: Updating max runtime to 0h 04m 00s
  tst_test.c:1625: TINFO: Timeout per run is 0h 04m 30s
