DVFS support on 8127

Terry Neill
Intellectual 600 points

Hi folks,

I'm trying to follow the instructions on this link:

http://processors.wiki.ti.com/index.php/TI81XX_PSP_PM_DVFS_User_Guide#Frequency_Scaling

Although I have followed the instructions here I'm not seeing any of the directories created as stated in the link, e.g,

/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
etc.
The only other message that I am seeing in dmesg is "omap_cpu_init:Regulatro get failed".
Is DVFS supported on the 8127?
I'm using EZSDK 5.05.
Thanks in advance,


Regards,




Terry

    Hi Terry,
    

    http://processors.wiki.ti.com/index.php/TI81XX_PSP_PM_DVFS_User_Guide#Introduction
    

    This wiki states that DM814x device supports DVFS, also the DM814x datasheet states the same.
    

    Thus I think you should check in the DM8127 datasheet whether DM8127 supports DVFS, AVS, etc.
    

    Regards,
    Pavel
