Yes, it will raise POST_BUF_EMPTY when set a mode, it needs some fix like [0]:
I still trying to find a appropriate way to do it with the upstream code, as it doesn't affect the
real display function(I must admit that the POST_BUF_EMPTY irq is very annoying), so l let it as
it is in the current version.
By the way, can you see the glmark2 rending on your HDMI monitor now?
