You won't get any nifty features, but you'll get a framebuffer. Hopefully we'll get a proper DRM video soon. The status is roughly as follows: LCDC: potentially supported by the Armada DRM driver. Patches sent to Russell King some months ago, not there yet. I'd prefer not to nag him. DCON: Russell dislikes the idea of a DRM bridge, DRM maintainers prefer if the driver was not a DRM encoder driver. This seems to require quite some work to fix [1]. [1] https://www.spinics.net/lists/dri-devel/msg201927.html GPU: supported by the etnaviv driver, good enough for 2D acceleration to work with xorg-x11-video-armada driver. 3D (weston and mutter alike) is broken. To add this to the device tree, the clock and power needs to be figured out. > Is there config somewhere I could use? > > Thanks a lot, > Pavel > -- > (english) http://www.livejournal.com/~pavelmachek > (cesky, pictures) > http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
