Hi Shuah, My two cents, The "cpupower" command is the pre-requirement of intel_pstate test case. Would it be a good idea to check, cpupower is pre-installed inside run.sh? If command not found exit gracefully. which cpupower if [ $? -eq 1 ]; then echo "cpupower: command not found" echo "intel_pstate: [SKIP]" exit 0 fi Test log: ------------ intel_pstate# ./run.sh ./run.sh: line 75: cpupower: command not found ./run.sh: line 76: / 1000: syntax error: operand expected (error token is "/ 1000") ./run.sh: line 77: cpupower: command not found ./run.sh: line 78: / 1000: syntax error: operand expected (error token is "/ 1000") ============================================================================== The marketing frequency of the cpu is 250 MHz The maximum frequency of the cpu is MHz The minimum frequency of the cpu is MHz Target Actual Difference MSR(0x199) max_perf_pct Best regards Naresh Kamboju -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
