Hi,
I am planning to buy a Juno development board for my research on power management. Does it support idle cycle injection through the OS - as included in the latest kernel update (https://lwn.net/Articles/757393/) or like the powerclamp driver from Intel (https://www.kernel.org/doc/Documentation/thermal/intel_powerclamp.txt)
Thanks,
Raghavendra
Hi Raghavendra,
The default Juno software deliverables may not include the idle cycle injection and powerclamp driver. But it is easy for you to cherry-pick those patches and build / replace your own Linux kernel into the Juno board.
Juno software deliverables can be referred to at:

What'more, Juno board also support Arm Energy Awareness Scheduling (EAS) technology and Intelligent Power Allocation (IPA) technology
