How to disable Powermanagement and how to map to memory-general Linux technology-Linux technology and application information is as follows. The younger brother is a cainiao and has just been in touch with linux for less than two months! If you have encountered some questions, please help me...
I am mainly engaged in high-precision clock, TSC and HPET.
But now I have a problem. I want to know if Powermanagement is disabled in the system (I have tried it in the bios, and there is very little information in the bios of many computers). If it is not disabled, how can I disable it. If any hero can know where this is in ACPI and how to map it to memory, I hope to be more detailed. Thank you!
