Bug Description
Scheduler test suite core_test_scn03.2a test case failed.
LSK Android build:
https:/
Linux version:
Linux version 3.10.16-
Scheduler test suite has latest patches dated Mon, 14 Oct 2013.
tasklibrary: Fix parsing priority token in case of interpolated load
root@vexpress:
Fast CPU 3,4 Slow CPU 0,1,2
Setting NODOWN_THRESHOLD to 65
Setting NOUP_THRESHOLD to 53
This starts with a heavy task however the task priority
is modified mid way through execution below cutoff. Since the
big domain is oversubscribed, the task stays on little domain
