    description: "Test CPU Isolation with NOHZ and CPUSETS on Linaro Ubuntu and OpenEmbedded builds.
                  The test can isolate upto (N-1) CPU's from list of N CPU's isolating it from other
                  background kernel activities and run user provided task (default 'stress') on the
                  isolated CPU(s) and figures out if CPU's are isolated or not by reading 'cat /proc/
                  interrupts' for all interrupts. ISOL_CPU, ITERATIONS and ISOL_MIN are set to 1, 5 and
                  10 respectively by default which can be changed via JSON file.
                  NOTE: Kernel configuration needed to run this test +CONFIG_NO_HZ_FULL=y
                  +CONFIG_NO_HZ_FULL_ALL=y +CONFIG_CGROUPS=y +CONFIG_CPUSETS=y"
