This is a script to manage the Switch GPU clock profiles. When shutting down, the current profile is lost -
|
|
therefore, this script must be called at each reboot to restore the default profile.
|
|
|
|
Written by natinusala for Lakka. See print_usage() for usage.
|
|
|
|
For now the profile is not retained and is set to default non-docked speed when rebooting.
|
|
|
|
L4T variant.
