No. That branch of mine is basd on linux-next, so whatever is in
linux-next is in my branch, and I certainly haven't applied the CDF
locally.
I believe the CDF has been posted to various mailing lists a few
times, but it isn't checked in yet since there isn't a final version.
I CC'd Alex; he might know the status better than me.
Current version is RFC v2 - I know Laurent is working on a v3, but it is
taking some time. It will probably differ considerably from v2, so be
warned if you use it.
Still, if you want to play around with the CDF, you can have a look at
the tegra-cdf branch of my github repo:
https://github.com/Gnurou/linux/commits/tegra-cdf
It was kind of old so I rebased it on top of 3.10rc1. It includes the
CDF v2 patch, adds CDF support to the tegra-drm driver, and also
implements a driver for the Tegra 2-based Ventana panel. It's pretty
straightforward to read so I guess you can use that as a guide.
I checked whether the rebase worked and it does - you just need to
enable host1x/tegradrm support on top of the default settings (Stephen,
why aren't these enabled by default?)
So long story short, CDF works well and is small enough to be easy to
maintain out-of-tree. A proper panel framework is desperately needed in
the kernel, so I hope it will move forward soon.
Hope this helps,
Alex.
