[Buildroot] questions about xdriver_xf86-video-imx-viv

[Thierry Bultel <tbultel@free.fr>]

Jerome,

I was also currently attempting to bring the work from yocto to 
buildroot. I do not have a working board, yet, since we are migrating 
our BSP from 3.0.35 to 3.10.17. Thus I am only preparing the 
integration, but cannot test at the moment.

There is something I do not understand.
With the previous version of xdriver_xf86-video-imx-viv ,
the build in the DRI directory was producing a libdri.so, which
was loaded by xserver.

For what I see, only $(@D)/EXA/src is built now.

libdri.so is not needed anymore ?


Also, when you say: " This driver should
+	  also be able to provide Desktop OpenGL implementation but, this
+	  feature seems broken for a while."

does that mean that windowed 3D does not work, but that only full screen 
does ?

Best regards
Thierry
