Hi,

I've upload a rebranded and cleaned up version of xf86-video-tegra to a
repository on gitorious[0]. Don't get too excited, since this is really
just a fork of the modesetting driver with some unnecessary pieces such
as PCI support removed.

Aaron had some reservations about calling this xf86-video-tegra because
it will clash with the binary tegra_drv.so provided by NVIDIA. However I
couldn't come up with anything more creative. Distributions will have to
deal with this in some way or another anyway and there really isn't a
way of running both drivers on top of the same kernel currently, so I
decided not to care.

You cannot run both drivers on top of the same kernel but the X server
could possibly load and probe both drivers in turn and keep the one
that can work with the current kernel.

Perhaps it could be named xf86-video-tegra-kms or something.

Thanks

exactly, don't shift the burden to maintain two name identical drivers for the 
same hw to the distributions.

or opentegra (to make clear that this driver is not the closed source one). I 
know this is a bit fanciless but it fits better IMHO.

Okay, those are good arguments.

I just remembered that back when I started working on Tegra DRM I wrote
some small utilities to help with the reverse engineering and some test
programs. At the time, some other projects were appearing and the trend
seemed to be to reverse the syllables of the original to obtain a new
name. So I went ahead and collectively named the utilities "grate". I'll
throw xf86-video-grate in as another potential candidate.

I actually like the name opentegra as it clearly states what's inside.

Now that we've heard some candidates for the naming, can we please come
to any conclusion?

I would like to start extending the DDX in the next days and it would be
really nice to have the naming thing out of the way for this.

Why not xf86-video-tegradrm, since tegradrm is the kernel driver it
talks to. It'd also help make it more obvious which user-space driver
to pick based on the kernel driver.
