Introduction

To load some class kernel calls user code. User code supposed to find class by connecting to network repository (which is not ready yet for now), or by some other means (distribution disk, for example). Actually, there's just one way to bring class to system: kernel native class loader. In future it will be used for bootstrap only, to bring initial set of classes to OS, but for now it is all we have.

Initial kernel class loader

Kernel class loader can load class from:

• Class bundle brought by multiboot loader as kernel module. See run/fat/boot/classes file, made in plib/sys.
• From FAT disk /class directory, containing .pc files with compiled Phantom VM classes. See run/fat/class/*.pc. This way it is simpe to debug Phantom userland code - compiler can put a copy of binary to run/fat/class/ for kernel to pick up.

TODO

Some way for kernel to reload class implementation runtime.
