I didn't say make framebuffer depend on DRM, you can still unload DRM before suspend. It's the other way around DRM needs framebuffer. Suspend/resume are part of this. In the current model there is no way for the DRM driver to see the suspend/resume events. I haven't tried it but I suspect a suspend/resume with DRM running has a bad outcome right now. -- Jon Smirl jonsmirl@gmail.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
