Some devices, namely Lenovo Legion devices, have an "extreme" mode where power draw is at the maximum limit of the cooling hardware. Add a new "max-power" platform profile to properly reflect this operating mode. Reviewed-by: Mario Limonciello (AMD) <superm1@kernel.org> Acked-by: Rafael J.

==================== ========================================

balanced-performance Balance between performance and low

power consumption with a slight bias

|

|

max-power Higher performance operation that may exceed

internal battery draw limits when on AC power

Date: March 2025

|
KernelVersion: 6.14
|
|
Description: Reading this file gives the current selected profile for this
|
|
device. Writing this file with one of the strings from
|
|
platform_profile_choices changes the profile to the new value.
|
|
|
|
This file can be monitored for changes by polling for POLLPRI,
|
|
POLLPRI will be signaled on any changes, independent of those
|
|
changes coming from a userspace write; or coming from another
|
|
source such as e.g. a hotkey triggered profile change handled
|
|
either directly by the embedded-controller or fully handled
|
|
inside the kernel.
|
|
|
|
This file may also emit the string 'custom' to indicate
|
|
that the driver is using a driver defined custom profile.
