# Open Firmware for OF816
|
|
|
|
|
|
|
|
|
|
This directory contains Forth source implementing Open Firmware on top of
|
|
|
|
|
OF816. It is based on IBM's [Slimline Open Firmware](https://github.com/aik/SLOF)
|
|
|
|
|
that is notably used in IBM POWER systems and QEMU.
|
|

**There are Bugs**
|
2020-11-06 02:05:38 +00:00
|
|
|
* Package instances don't quite work right.
|
|
|
|
|
|
|
|
|
|
Working features:
|
|
|
|
|
* Device tree.
|
|
|
|
|
* Properties.
|
|
|
|
|
|
|
|
|
|
Unimplemented features:
|
|
|
|
|
* FCode additions (to-do).
|
|
|
|
|
* nvram (board-level addon).
|
|
|
|
|
* Framebuffer/display support (to-do).
|
|
|
|
|
* Device probing (to-do).
|
|
|
|
|
* Support packages (to-do).
|
|
|
|
|
* FCode debugging and Forth source-level debugging (probably won't do).
|
|
|
|
|
* Client interface.
|
|
|
|
|
* Other miscellania.
|
|
|
|
|
|
|
|
|
|
Difficulties:
|
|
|
|
|
* SLOF is based on a 64-bit system. The basic stuff ports to 32-bit
|
|
|
|
|
easily enough, but the cool stuff like FAT and ext2 support rely on
|
|
|
|
|
the 64-bit extensions.

|
|
|
|
|
|
|
The build script borrows tricks from SLOF to incorporate the C preprocessor
|
|
|
|
|
and remove comments and extra lines from the code, producing a single file
|
|
|
|
|
that can be used with EVALUATE.
