I'm currently running a 3.19-rc kernel with imx6 drm (fbdev emulation) and it works, but I'm seeing segfaults from Xfbdev. Presumably, theres a proper DRM/DRI X driver to go with the kernel bits? Where can I find that?

There is the xf86modesetting driver: http://cgit.freedesktop.org/xorg/driver/xf86-video-modesetting/ There's no dedicated i.MX X driver that works with imx-drm.

Im not currently "up" on how the whole stack works - is this driver generic to anything using kms? do I still need fbdev? Is there a good overview of things, particularly wrt. imx6? -Ian _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 4+ messages in thread

The xf86modesetting driver should work with any kms driver (though it's been some time since I last tested it with imx-drm) You won't need fbdev, but without it the kernel does not activate the display during boot, so it will just stay dark until X starts. > > Is there a good overview of things, particularly wrt. imx6? Not that I know of, at least there's no i.MX specific drm documentation.
