Kernel Configuration

Darwin includes configuration directories for each major component of the operating system, as listed here:

xnu/bsd/conf

Contains configuration files for the BSD portions of Darwin.

xnu/iokit/conf

Contains configuration files for IOKit, Darwin’s subsystem for device drivers.

xnu/libkern/conf

Contains configuration files for libkern, a set of base classes for kernel C++ code.

xnu/libsa/conf

Contains configuration files for implementations of standard C library functions that are used by the kernel.

xnu/osfmk/conf

Contains configuration files for the Mach portions of Darwin.

xnu/pexpert/conf

Contains configuration files for pexpert (platform expert). This is for low-level hardware support during the boot sequence.

libsa and pexpert are private to the xnu kernel and should not be used by kernel extensions.

To tweak machine-independent aspects of a Darwin kernel component, you can edit the MASTER file in each configuration directory. You can find machine-dependent configuration options in MASTER.i386 (for x86 systems) and MASTER.ppc (for PowerPC systems).
