RobertCNelson: Or you could take Rob Clark's advice. http://lists.freedesktop.org/archives/dri-devel/2014-March/055477.html First it seems to complicated. Now I found some really nice examples of how to use drm. You're right, thats the way to go.

Re: [beagleboard] Re: FBIO_WAITFORVSYNC on BBB
RobertCNelson: Well the Sitara am335x use on the bone's doesn't have the omapfb display ip block. On mainline it uses the tilcd driver, based loosely of the same ip as the davanci da8x-fb driver. Hi, it seems the da8xx driver supports the FBIO_WAITFORVSYNC ioctl. I tried to use this driver with my bone. So I compiled a new kernel with da8xx support and removed the tilcdc driver. But now I have no output on hdmi. What did I forget? Do I have to change a dtb file or something like that?

Oh, I see. Any chance to get the vsync signal with that in userspace or i a kernel module?
