Scott, All,

On 2015-07-28 22:15 +0800, Scott Fan spake thusly:
> Add the fbturbo video driver, which is based on xf86-video-fbdev (with
> none of the original features stripped), primarily optimized for the

I've tried to build this package, and all by itself, it is OK.

However, we do have a dependency issue in how we handle DRI2 in our Xorg
stack, which is triggered by this patch.

So, before we can integrate that patch, we need to fix the DRI2 stuff.
I have a series in my tree handling that dependency fix, so I'll drag
this fbturbo in my series.

In the meantime, I'm marking this patch as "Deferred" in our Patchwork.

No need to resend it, I'll be taking care of it carying this patch in
my tree now.

Thanks! :-)

Regards,
Yann E. MORIN.
