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?
