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!
• Head over to here for a list of pages that need some work done on them.
• Or you can go here for a list of pages that need images uploaded.
• An archive of the old content is available here - if you see anything there that isn't here just use the re-formatter on the main page to turn it back into wikitext and copy it in!
• 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

- You can use the big-endian compatible 2.4.32 fatx patch from the xbox-linux project and port it to 2.6.3x - Thx zinga! http://xbox-linux.cvs.sourceforge.net/viewvc/xbox-linux/kernel/
- Probably even the freebsd patch will help - Thx Rene Ladan: http://file.libxenon.org/free60/bsd/freebsd_xtaf_module.zip

• [XeLL]: Implement parsing of a bootconfig + passing bootarguments to the linux kernel DONE
• [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)
