FEAT: cpuscaling test should be run separately for each cpu
Last modified: 2014-03-25 20:55:38 EDT
Description of problem:
The cpuscaling test should be run separately for each cpu. It should
set governors and speeds for specific cpus, and set task affinity for
the workload to the cpu under test.
Version-Release number of selected component (if applicable):
HTS 5.2 R18
Created attachment 317490 [details]
This patch changes cpuscaling test planning to plan a separate test for each cpu. The test is also changed to test a specific cpu, including the use of task affinity via taskset to insure that the workload is run on the intended cpu.

This revised patch changes the planning logic. A test is scheduled for each cpu if ANY cpu reports can_throttle as True.
Verified "hts plan" in hts-5.3-12 setup separately for each cpu, so could run separately by specifying device or UDI for each cpu.
