Want to Help?

Here is what you can do to help this project:

Documentation: We need the individual bits&pieces, for example from xboxhacker.net, nicely assembled into wiki pages, Howtos etc. This does not require coding skills!
Take a look at wiibrew.org: They have nice categories for the available software, features applications etc.
Tell more people about what you can do with Linux on the 360.
We need more applications so people have a reason to try out free Libxenon based code and Linux on 360.
Work to implement End User Requirements
Test and improve the Linux live CD images
Add useful ideas to this list.

Seeking Information On

Some documentation must already exist, though perhaps not in the wild. We are seeking:

CPU instruction set reference --> See VisualStudio 2005 Reference (Exact CPU instruction set reference)
Verification that the CPUs have a memory management unit (can do virtual memory)
Details of Multi-processor memory coherency and synchronization requirements

Documentation To Develop

Some documentation will either not exist, or won't be made available

Memory usage map for boot code
Hypervisor details. What is checked and how it is checked
Chain of trust: how execution integrity is designed to work
Chinks in the armor: Holes in the chain of trust
~~Hard drive locking (if any) and~~ filesystem details (Harddrive)
Wireless hardware and software protocol for controllers
Xbox1 software emulation details

XeLL / Libxenon

[Libxenon]: Improve Libxenon and write apps.
~~[Libxenon]/[XeLL]: Fix the usb driver so it gets proper speed and Power supply does not need to get replugged to get usb mass storage recognized~~ DONE
[Libxenon]/[XeLL]: Write a fatx/xtaf driver
[XeLL]: Implement parsing of a bootconfig + passing bootarguments to the linux kernel
~~[XeLL]: Fix non-workin XeLL-XeLL implementation (chainload XeLL from a "base XeLL")~~ DONE

Xenon linux kernel

Needs urgent fixing: Linux Kernel - a hardware CPU bug causes powerpc locking primitives to fail between hyper threads unless a special register is set properly
Fix usb driver (random freez under heavy usage)
Patch RTC driver for hardware clock access
Xenosfb: add support for mode switching
Audio driver
If possible: Modify the ATI 3D driver to work with the Xenos-Chip

Linux Live CD / Installer

Open a Boot Menu with the following options:
- Load [Linux Kernel] from HDD (default, 10s timeout? auto detection of valid Linux HDD?)
- Load [Linux Kernel] from CD and use root filesystem on HDD
- Load Rescue/Installer Linux LiveCD
- Load Linux over TFTP (optionally configuring the network)

The Menu can either be created in XeLL (requiring reading from CD, SATA, plus interactivity over serial / IR remote or USB controller), or possibly in a Linux initramfs (which is easier to implement, but locks the user in to one single kernel)

-Ideally, what we need is a binary patch for KK, resulting in a single DVD-DL doing the following:
-* Load KK shader exploit
-* Start [http://www.free60.org/XeLL XeLL] from the same disk (video partition?)
 * Open a Boot Menu with the following options:

-Such a disk would allow using one single DVD-DL for all tasks, from Linux installation to daily bootup and recovery. Packing everything on a single disk also allows booting Linux without disk swapping, serial console, etc., making it really convenient.
-There is a problem with the implementation though, we can only access around 200MB of the KK disk (the video partition), or only the game data, depending on the mode of the drive.
