*Sound support (ALSA hda-intel module does not detect any codecs)
*A sane way for framebuffer support.  
*A sane way for framebuffer support.  
*Better graphics support (changing resolutions etc.). Might require SMC support for talking with the Ana.
*Better graphics support (changing resolutions etc.). We need to add the GPU to the Xell OF tree so Linux detects it correctly. We can probably reuse great part of the ATI/AMD open source drivers available.
*Maybe: patch to work around the samsung (and possibly hitachi) drive differences (plus: eject support over SMC).  
*IR remote support
*(Wireless) Xpad support in xpad.c
*IR remote support

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

Currently we have the following patches working against 2.6.33 kernel:

  • 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 , including RTC and communication with Ana.
  • Xenon FB (ugly): adding support for tiled framebuffer
  • Sound Support
  • Pad Support

User:Bertl is currently working on them. Please contact him you want to help on the IRC.

Currently missing are:

  • A sane way for framebuffer support.
  • Better graphics support (changing resolutions etc.). We need to add the GPU to the Xell OF tree so Linux detects it correctly. We can probably reuse great part of the ATI/AMD open source drivers available.
  • IR remote support
