The Raspberry Pi config.txt file is read by the GPU before the ARM core is initialised. It
can be used to set various system configuration parameters.
This file is an optional file on the boot partition. It would normally be accessible as /boot/
config.txt from Linux.
To edit the configuration file, see the instructions at R-Pi_ConfigurationFile.
You can get your current active settings with the following commands:
vcgencmd get_config - lists a specific config value. E.g. vcgencmd get_config arm_freq
vcgencmd get_config int - lists all the integer config options that are set (non-zero)
vcgencmd get_config str - lists all the string config options that are set (non-null)
