help
If you need patches applied to your vanilla kernel
you can specify a series file here. A series file
is a textfile with one patch per line.
This file lies usually in your project directory,
so the default is $(PROJECTDIR)/series.
The patches given in the series file must be relative
to the series file
config KERNEL_CONFIG

Usually config files for the kernel live in $(PROJECTDIR), so
add something like

here.

Usually you want to compile your kernel. If not,
deselect this option.

Say yes if you intend to use an external already configured
kernel tree. You want this if you, for example, are currently
working in a kernel tree and don't want to generate patches
for each and every PTXdist run.
config KERNEL_DIR

Add a path to your external kernel here. The kernel must be
configured.

When compiling with NATIVE=1 it is possible that you build an
UML kernel which runs on the host as a virtual machine.

the host and the user mode linux machine.

This switch adds "ssl0=fd:0,fd:1" to the kernel command line,
which forwards /dev/ttyS0 of the user mode linux vm to the
host's stdin/stdout.

Add your custom kernel commandline for the user mode linux
kernel here.
