      8		====================	========================================
      9		low-power		Low power consumption
     10		cool			Cooler operation
     11		quiet			Quieter operation
     12		balanced		Balance between low power consumption
     13					and performance
     14		balanced-performance	Balance between performance and low
     15					power consumption with a slight bias
     16					towards performance
     17		performance		High performance operation

     26Description:	Reading this file gives the current selected profile for this
     27		device. Writing this file with one of the strings from
     28		platform_profile_choices changes the profile to the new value.

     30		This file can be monitored for changes by polling for POLLPRI,
     31		POLLPRI will be signalled on any changes, independent of those
     32		changes coming from a userspace write; or coming from another
     33		source such as e.g. a hotkey triggered profile change handled
     34		either directly by the embedded-controller or fully handled
     35		inside the kernel.
