LS1043A is a system used without FAN, and is looking for a way to reduce power consumption.
I first answered the question by answering the link below.
Two additional questions.
Does SWLPM20 mode disable all cores?
Or can I disable individual cores?
I want to run only one core. If you can do that, you would expect a saving of 0.2 x 3 = 0.6 watt.
Is there a way to do core-specific power gating?
