The provided helpers are compatible with the requirements of most DRM drivers. The helpers handle support for VGA switcheroo automatically. With DRM drivers that don't implement VGA switcheroo, this does nothing. The helpers also support DRM drivers with non-atomic mode setting, which require additional steps to disable their modesetting pipeline. Compared to its current implementations in various drivers, there is one difference in drm_fbdev_helper_client_hotplug(). The custom functions perform hotpluging if struct drm_device.fb_helper has been set, while the custom helper tests for struct drm_fb_helper.info. Both fields signal the presence of an active fbdev emulation, but the former field is deprecated.
