Over the past few years, the vast majority of notebook manufacturers have placed strong emphasis on power consumption,
requiring support for S0ix with very strict power efficiency targets.
As a result, we updated the driver to further reduce power consumption.
To address this issue, it seems necessary to provide a mechanism that allows games or user-mode applications to dynamically enable or disable the power-management (PM) functionality.
