I'm specifically interested in the Atom N2600 which has a GMA3600 > (0x8086:0x0be1 to be exact). I believe there are GMA600 and 3600 bits buried in the packages for Maemo/Meego/Tizen vaapi code but I've not looked. > I'm also not sure which kernel driver this was developed against.

I've been working on Cedartrail primarily at the moment so not had time to dig further into the video playback logic. I did get the decoder detected and mapped happily but haven't yet had time to persuade the firmware to upload. It'll also need the driver extending to support the overlay planes feature in the DRI/DRM layer. > Do you think that would be doable?
