Do you have a pointer to the OLPC tree?


They are working in the olpc-2.6.30 branch, currently.

Thanks. After having a look at it seems concerning viafb to be mostly Haralds patches with 1 or 2 extra ones.

I'd really like to see VX855/OLPC support in mainline as soon as possible as I consider it a good thing to support "new" hardware early. However even if I am capable to write such support based on Haralds work I don't want to see it in mainline as long as no one with that hardware tested it.

I do have the hardware, and I've taken on the responsibility for making
pieces of it work. In my mind, that includes being responsible for
mainlining things too. I will start to work in that direction; 2.6.33
should be a reasonable target for the bulk of it.

My thinking, FWIW, is to turn the viafb code into something more like a
regular multi-function device driver. I've already integrated Harald's i2c
stuff with the OLPC code; I need to add proper GPIO support next. Then
there will be the V4L2 chunk for the video capture engine. Along the way,
I may try to introduce some foreign concepts like locking.

Feel free to add the things you like. The main objective is probably to get things working and stable. I do not have an idea how good that will work out as I don't know how much code that requires. If you think that's the way to go, then we'll try it and see whether it leads to something usable and maintainable.

I have a tree on now, but it's against the 2.6.30 base. I will
try to bring things forward to a more current tree sometime soon and put it
up as, at least, a place where we can see the various lines of development
going on.

Sound good?

Jep, that's fine with me. I'll try to rebase&integrate the patches I consider interesting from Harald's tree in -mm. I guess that's a good thing to do as that's the latest used common base.
Any objections?
