    drm_fb_cma code has a nice helper function to display in the debugfs
    information about the underlying framebuffers used by HDLCD:
    
    $ cat /sys/kernel/debug/dri/0/fb
    fb: 1920x1200@XR24
       0: offset=0 pitch=7680, obj:  0 ( 2) 001011ba 0x00000000fc300000 ffffff800a27c000 9338880
