How to enable/disable Intel turbo boost technology


Jianjie Lin
 

Hello acrn project teams,

 

Here I would like to ask about the Enable and Disable feature of Intel turbo boost technology.

As I know that for a PC if I want to disable the intel turbo boost technology, I need to set the BIOS setting before booting the system.

But for the hypervisor type1, I would like to ask if it is possible to set the turbo boost technology for each UOSs individually.

 

For example, I have to UOSs: Uos1, Uos2.

I want to enable the turbo boost technology in the UOS1 but disable this feature in the UOS2.

 

I found the device model parameter offers a flag.

-B, --bootargs <bootargs>

    Set the User VM kernel command-line arguments. The maximum length is 1023. The bootargs string will be passed to the kernel as its cmdline.

    Example:

    -B "loglevel=7"

    specifies the kernel log level at 7

 

Therefore, I would like to ask if it is possible to use this flag for setting this parameter. If it is possible, how can I write the cmdline?

Thank you very much for your support.

 

Cheers

Jianjie Lin
