CONFIG_64BIT

(No prompt – not directly user assignable.)

Type: bool

Help

This option tells the build system that the target system is using a 64-bit address space, meaning that pointer and long types are 64 bits wide. This option is selected by arch/$ARCH/Kconfig, soc//Kconfig, or boards//Kconfig and the user should generally avoid modifying it.

Defaults

No defaults. Implicitly defaults to n.
