Linux Kernel Development

Currently we have the following patches:

• PCI: adding PCI_VENDOR_ID_MICROSOFT (trivial)
• Xenon CPU: adding Xenon into cputable
• Xenon Platform: adding Interrupt controller, SMP support, setup
• Xenon SATA: adding the sata_xenon libata driver
• Xenon SMC: adding support for the SMC
• Xenon FB (ugly): adding support for tiled framebuffer

User:Tmbinc is currently working on them. Please contact him you want to help.

Currently missing are:

• Sound support (ALSA hda-intel module does not detect any codecs)
• A sane way for framebuffer support.
• Better graphics support (changing resolutions etc.). Might require SMC support for talking with the Ana.
• Maybe: patch to work around the samsung (and possibly hitachi) drive differences (plus: eject support over SMC).
• (Wireless) Xpad support in xpad.c
• IR remote support

The Samsung drive hangs the SATA device detection, a console dump with SATA debugging looks like this:

this requires someone with some more libata knowledge - GeorgLukas 12:43, 22 Apr 2007 (PDT)

New, experimental patches which should cure the samsung problem are available from http://op-co.de/xbox360/2.6.21/ . Tmbinc 15:53, 1 May 2007 (PDT)
