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) andfilesystem 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
- Libxenon/XeLL: Write a fatx/xtaf driver
- XeLL: Implement parsing of a bootconfig + passing bootarguments to the linux kernel
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
Ideally, what we need is a binary patch for KK, resulting in a single DVD-DL doing the following:
- Load KK shader exploit
- Start XeLL from the same disk (video partition?)
- 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)
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.
