Hi,

I am implementing HDMI hotplug feature for i.MX6 platform, the basic function has already been done and works

But there is is an "issue", When bootup system without HDMI cable attached, fbdev is initialised with fbsize: 1024x768, after plug-in HDMI cable, I can see in debug log, display's valid video_mode has been read via DDC, but in drm_fb_helper_hotplug_event(), only size lower than fb_helper->fb->width/fb_helper->fb->height, will be accepted,

So instead of the display's native mode, 1024x768 is displayed.

Is it correct DRM/fbdev behaviour? or is it possible to resize fbdev, to show bigger resolution after new monitor is plugged-in?

Thanks, Jiada
