··· 1 + What: /sys/devices/platform/<platform>/tt_toggle 2 + Date: Jun 2023 3 + KernelVersion: 6.5 4 + Contact: "Antheas Kapenekakis" <lkml@antheas.dev> 5 + Description: 6 + Takeover TDP controls from the device. OneXPlayer devices have a 7 + turbo button that can be used to switch between two TDP modes 8 + (usually 15W and 25W). By setting this attribute to 1, this 9 + functionality is disabled, handing TDP control over to (Windows) 10 + userspace software and the Turbo button turns into a keyboard 11 + shortcut over the AT keyboard of the device. In addition, 12 + using this setting is a prerequisite for PWM control for most 13 + newer models (otherwise it NOOPs).
