Hi, Jessa/Eric
How about this patch set?
In this patch set the default modes are added in user space. At the
same time I also use the LVDS panel limit to check whether the modeline
is valid.The modeline added by xrandr tool can also be validated.
Will you please review the patch set? Is something missing in my patch
set?
Now it seems that this is the KMS gap. Xrandr tool will get less modes
for LVDS output device than KMS mode.
Thanks.
