--- Comment #12 from HuangRan <huangran at iscas.ac.cn> ---
I found a link in OpenChrome:

https://www.freedesktop.org/wiki/Openchrome/TtmGemKms/

It is said that:

(kernel) KMS for VGA is working nicely.
(kernel) KMS for LVDS is mostly working.
(kernel) KMS for HDMI/DVI is in the works.
(kernel) KMS for DP is not started.

I think that can explain why HDMI has issue right now with current KMS driver.
Although I am not sure how it goes after this wiki page is edited, but till now
with latest drm code, the HDMI is still not working(by the way, DP is not
working too).

So next step should be reviewing current VIA's close driver KMS code and see
what has been done in that driver which can make HDMI working.

Thanks,
Frank
