LIN6-1168 : P-STATE is not supported on Atom C2000 processor family

Created: Oct 12, 2013    Updated: Apr 19, 2018
Resolved Date: Apr 17, 2018
Found In Version: 6.0
Severity: Severe
Applicable for: Wind River Linux 6
Component/s: BSP

Description

This could be re-produced with latest 3.12-rc4 kernel on mohon peak or tiger cove boards, I believe ATOM C2000 PSTATE is not supported yet, see the result of running BTS CPU_FREQ:

Not found the kernel fragment for testing CPU_FREQ, Continue test.
CPU_FREQ.pkg readable!
lmbench-3.0+a9-r9.0.x86_64
Found the lmbench package installed.
cat: /sys/devices/system/cpu/cpu7/cpufreq/scaling_available_governors: No such file or directory
NO supported governor available

Steps to Reproduce

1. build with BTS
2. cd /opt/wr-test
3. ./main_test.sh -s CPU_FREQ
